With the iPhone 12, it is only a year away from a quarter. At this node, I was lucky to receive the Nelkin magnetic suction and lens painting protective case from ZEALER. Especially in the form of the Guangzhou epidemic, it is very happy to be able to sit quietly in the residence and experience the product slowly. Next, I will share the experience of the whole set of products under the shell film + wireless charging.

iPhone 12 magnetic + lens sliding cover protective shell & film:

Green

1. The skin-friendly is particularly strong, the patented sliding cover lens protection design is easy to use, and the lens ring has a unique heightening to prevent the lens from scratching and dusting.

2. The official display shows that there are 38 built-in magnets, which is convenient for magnetic charging, and the Magsafe is stable when it is sucked in.

3. The inner lining is soft fiber, which can better protect the body. The back is also very simple. 4. The body is surrounded in place, and a relatively protective layer can be felt almost all over the body. However, the same skin-friendly soft glue as the surface is used directly at the interface position and button position of the mobile phone, which is very good for the protection of the product. Will affect the use. 5. It feels a little tight to use. Black Mirror Pro sliding cover goggles: 1. The design is really steel. Looking at the business, it feels like a military industry when holding it. The gap between the sliding cover and the shell is tight, and there is a hidden buckle designed to prevent the lens cover from loosening. 2. The hand feeling is naturally a protective hand feeling. When I put it on my hand, the strong scratching feeling of the original iPhone 12 is gone, but the overall feeling is the kind of friction that is protected in place. It does not increase the friction of the hand and it is durable. Carefully on the ground, nothing happened when I picked it up. This picture was taken after I fell, and there is no trace of falling. 3. Looking at the material, the original side is TPU soft glue, which is very friendly to the button interface, etc., while the back is the PC back shell, which is still very good for product protection. 4. Magnetic attraction is also very powerful. Correspondingly, it will naturally be a little heavier if the material is full. Full screen privacy protection film 1. The packaging is very different. In addition to the film itself, it also brings a small thing similar to paper towels. More importantly, it is the gospel of a handicapped party-the film applicator, which can be applied directly, and it can be applied without too much effort. . 2. 28-degree side anti-peep, anti-fingerprint, full coverage, with dust-proof net, 0.33 slim, sensitive to the touch, very friendly to use, but face recognition occasionally affects. 3. Anti-peeping is really useful, you don’t have to worry about being peeked anymore in daily use 4. Tempering treatment adds another layer of protection for daily use. The official display is composed of oleophobic coating, explosion-proof film layer, Japanese AGC material, and silicone coating, which once again enhances the protection of mobile phones.

Magnetic wireless charger:

1. The casual black Magsafe magnetic charging, smooth arc edge, round and smooth, feels good to use, will not scratch your hands, is also very friendly to mobile phones, will not scratch the mobile phone. 2. It’s easy to stick in place, suck it up immediately, charge it up immediately, and quickly replenish energy. Supports up to 15W, which is very convenient for charging mobile phones. 3. The compact body is close to the original thickness, only 5.2mm. The front is a mirrored minimalist design, and there is only a NIILKIN LOGO on the back. Just simple and capable. 4. Over-temperature, over-voltage, short-circuit and over-current protection, as well as metal foreign body detection, which is particularly friendly when charging mobile phones. 5. Compatibility is particularly good. The mobile phone can be charged, and another interesting thing is that it comes out of the main body, it has a C port, and then another C2C cable, and at the same time I gave a small adapter from the C port to the A port. I like this very much. . to sum up: After a whole set, I found that Nelkin’s product idea is really good. It protects mobile phones in place, and then takes into account all aspects, and meticulously solves all aspects of mobile phone use. I personally recommend it

Internet capital’s routines have always been based on low prices or even free of charge. The widely-familiar online car-hailing and takeaway industries are all like this. They enclose land at low prices. After they have a monopoly market share, they have increased their prices significantly. Now the price of online car-hailing It is already more expensive than taxis, and the takeaway industry has forced catering businesses to go nowhere, leading to the consequences of bad money driving out good money. A considerable proportion of takeaways directly turn factory-supplied food bags into fast food boxes.

After the capital has gradually harvested many industries, now it has begun to target the last outlet of the middle-aged and elderly-the vegetable vendor. The routine is still so familiar, and it grabs the market at a low price, with the intention of killing the vegetable vendor and waits for the vegetable market. All were forced to close and then raise prices drastically, and this process is still in progress.

For public services such as the power grid, there have been similar cases at home and abroad where capital seized the market and then maliciously increased prices. In the 1990s, Britain promoted privatization and the British gas company was privatized. After the privatization, the British gas company increased its expenses year after year. As a result, the British could not consume fuel. In desperation, they could not turn on the heating in the cold. Cold Bird”.

In the domestic market, foreign capital structures such as Veolia and Suez have successively acquired water supply networks in more than 10 cities. Before the acquisition, they painted a beautiful picture. However, after the acquisition, they did not invest heavily in improving the water supply network. Prices have been raised year after year. In 2014, many cities across the country had odor incidents of tap water, and almost all of the water supply networks in these cities were acquired by foreign capital, which made people rethink the pros and cons of privatizing public services.

Today’s charging services that capital intends to intervene will undoubtedly be similar to previous capital stories. They try to seize the market at low prices or even for free. After occupying the market, they will inevitably increase prices. After all, the ultimate goal of capital is to obtain huge profits. .

However, this time the capital is facing the giant State Grid. State Grid has built the largest charging network in the country, comparable to Sinopec and PetroChina in the era of fuel vehicles. State Grid can quickly build a huge charging network and its own National Grid. It is inseparable as a solid foundation, and this has become its confidence.

As the State Grid has issued a warning to some charging operators, it cannot be ruled out that it will take other measures in the future. After all, with the State Grid as the foundation and power resources in its hands, these vicious competitors will face penalties at any time.

The author supports State Grid’s punishment of these vicious competitors, because it has repeatedly proved that private capital has no bottom line for profit after monopolizing an industry, and State Grid, as a non-private entity, is better able to ensure service quality due to more supervision. And provide reasonable prices.

Internet capital has received a lot of praise for a long time, but as they have achieved monopoly status in multiple industries, the people are disgusted by the people. All parties are becoming more familiar with the behavior of these capitals. There are just a few routines back and forth. I don’t believe in the beautiful vision they portray, but I believe that the ultimate purpose of capital is to make money.

LTS: Working at the first newspaper to charge readers in Vietnam, journalist Tran Tien Duan, Editor-in-Chief of VietnamPlus e-newspaper said that charging readers is a trend of the world’s press. To collect fees effectively, newsrooms must orient the production of content for paying readers that specialize in specific areas and must make a worthy investment to improve the quality of articles. Big, hot issues are at the forefront. VietNamNet would like to introduce the following article of Mr. For online newspapers, revenue is mainly from advertising and media contracts. However, now, there is a big shift when businesses choose advertising media through social media more instead of advertising on electronic newspapers. The transformation of advertising methods and the reduction of revenue is a really challenging economic problem for newspaper leaders. E-newspapers want to survive and develop, they need to find new forms of journalism economy, in which fee collection can be a solution for electronic newspapers in Vietnam. Editor-in-Chief of VietnamPlus Online Newspaper Tran Tien Duan Fee collection at VietnamPlus e-Newspaper There are many newspapers in the world such as Wall Street Journal, New York Times, Washington Post (USA), Financial Times, The Economist (UK), Svenska Dagbladet and Aftonbladet New Media (Sweden), Folha de São Paulo (Brazil). .. had early success with the digital-based fee model, before the growth of online advertising revenue slowed down and even declined in recent years. In addition, a harsh reality that has emerged in recent years is that up to 75-80% of digital advertising revenue flows into the pockets of two giants Google and Facebook. Because of that, newspapers found that they could no longer depend on advertising revenue, so charging readers really became a trend of the world press. On June 20, 2018, VNA’s online newspaper VietnamPlus became the first and only Vietnamese press agency to collect fees for reading content on digital platforms. Every day, VietnamPlus only distributes about 5-10 fee-based articles, including in-depth analysis articles, exclusive interviews, etc., produced by the newsroom itself, or translated under the franchise of major press units. In the world. Because the quantity of news sold is small, it does not affect the provision of essential information to serve readers and still ensures the principles and orientation of the VNA. VietnamPlus is the national foreign affairs electronic newspaper under the VNA. Therefore, the newspaper has many advantages due to the information system of the VNA and from 90 resident agencies at home and abroad. Therefore, VietnamPlus has more advantages when it comes to building specialized and in-depth content for its premium products, creating “commodity” products of high value and use value. Target a wide audience willing to pay to own that unique article or news. Interface of fee collection page of VietnamPlus newspaper The content that VietnamPlus has been collecting fees for focuses on 4 main areas: Politics – society, world, economy – technology and culture – sport. These articles are analyzed from multiple perspectives, and more importantly, have a lot of exclusive information because they are provided quickly, timely, and attractively by resident correspondents abroad. public interest. Regarding access organization, while The Straits Times and other fee-based online newspapers often put both paid and free content on the same website, Vietnam Plus separates the fee to https: //pay.vietnamplus.vn and free at https://vietnamplus.vn. This is to avoid offending readers who are not used to paying for e-newspapers, but will also affect the ability to cross-promote for subscriptions. In the near future, the newsroom is also planning to change it to allow partial reading, creating an incentive for users to be willing to pay. Taking the first step on a new path, VietnamPlus e-newspaper has constantly learned from the electronic newspaper fee models in the world, researched the information needs of domestic readers to build and develop this model. in your own newspaper. Currently, VietnamPlus uses many strategies to achieve its goals: Periodical newsletters, information on specific topics (politics, economics, culture, science) to attract subscribers to target each audience. customers and targeting each specific customer group on Facebook, Google does not use advertising to bring its posted content to potential new customers. Vietnamplus aims to continue to produce high-quality, long-form content such as mega-story, long-form, and not only restrict the content to economic, financial, strategic, and business secrets, but also open it up. other fields such as technology, sports, entertainment, politics, new trends, forecast information… and collect fees from these articles. Some problems raised in electronic newspaper fee collection In the economic activities of journalism, in order to collect fees effectively, newsrooms must orient the production of content for paying readers to specialize in specific areas and must make worthy investments to improve the quality. posts. Big, hot issues come first, otherwise there would be no reason to convince people to subscribe. Because the readers who can afford to pay are often businesses, researchers, press agencies, people with high income and qualifications, they need information from experts, managers, comment on a topics that are important to them. A newsletter from the VietnamPlus e-newspaper Through polling and surveying the groups and individuals that buy information from VietnamPlus, they found that the news sold has a high content of information, going deep into a field or issue that public opinion and society are interested in. Such news they accept to pay for the source of information they are using. Through this, VietnamPlus also determined, selling news must focus on readers, must find a way to determine what their readers need. Readers will spend money when they really believe that they have valuable, quality sources. And the question is: how can we create many “goods” that are attractive enough to users, making them “pickpocket” to pay? Payers buy high-quality content, not cheap. Readers pay for content because it helps them stay informed and post about issues they care about. And readers appreciate the exclusive content they have access to more than ancillary benefits like promotional giveaways when they sign up. Paid readers send a clear signal that news outlets that want growth cannot cut costs. Acquiring a paid audience requires an investment in high-quality content and a focus on meeting the needs of the audience. It is not easy to convince readers to pay when they are used to free information, so VietnamPlus’s pioneering in this field is also to help readers get used to reading paid newspapers. money. Must-know content turns free readers into paying readers. Informative, insightful, specialized content motivates readers to withdraw, which is the key to retaining readers. It is also about turning the habits of readers into our habits, understandable that when readers accept to pay for an information, it means that it is the act of paying for their own habits. Therefore, VietnamPlus e-newspaper also focuses on the habits of its readers. Habits are the best way to increase engagement. In addition, a difficulty in selling news is due to technology limitations. When it was newly built to collect fees, VietnamPlus’s method was still limited to only using mobile phones from a network operator. Currently, payment gateways have been expanded, allowing a variety of other payment methods such as bank cards, e-wallets, QR codes… VietnamPlus is planning to upgrade the payment system. Moreover, the fact that copyright in Vietnam has been a difficult problem to solve for many years. A good article just published in a certain newspaper will immediately be copied in its entirety. If a newspaper has a lock on its special articles and only provides them to paying readers, it is also difficult, because a website that aggregates information only needs to spend a little money to read and ” collage”, then this information will no longer be “poisonous”. Because of these reasons, it is understandable that the trend of charging readers to read e-newspapers in Vietnam is prone to failure right from the start. Collecting money from online readers in Vietnam is very difficult nowadays, but if they want to change the revenue structure, press agencies have to start working. The most important thing is to protect copyright, not to let a good article be cut and pasted by dozens of other websites on your site comfortably. The locking of articles and invitations to buy online newspapers need to be carried out simultaneously in many newspapers to create a positive effect. In 2019, Vietnam’s online advertising revenue was estimated at 648 million USD, of which Facebook accounted for 275 million USD, Google 174.9 million USD, domestic units accounted for only 180.9 million USD.

By Christoph Arnowski, BR A high proportion of electricity from coal, insufficient range, too few charging points – all this makes many people doubt the electric car. Also the Ingolstadt engineer Roland Gumpert. That is why he has developed a completely new electric drive concept that works without a charging cable and still enables a long range – and with which the car can be refueled as easily and quickly as a petrol or diesel. The technical core is a methanol fuel cell. If these are fed with climate-neutral methanol, their cars will run without greenhouse gas emissions, says Gumpert: “We can install this concept in any car, in a Polo with 50 hp or in a long-haul truck with 40 tons,” says the engineer. “We are vastly superior to normal battery cars.”

“Father” of the Audi Quattro

Gumpert isn’t just anyone in the automotive industry. For decades he worked successfully for Audi – most recently as Marketing Director for the joint venture between VW and Audi in China. At the beginning of the 1980s, as head of Audi Sport, he and his rally drivers brought four world championship titles to Ingolstadt. The basis was the Quattro drive, which was considered a technical sensation in 1980. For the first time, an automobile manufacturer built a permanent four-wheel drive into its street car. Gumpert is considered one of the fathers of the Quattro drive.

Billions invested in electromobility

Now, at the age of 76, Gumpert wants to show it to the entire industry again – with his own small company. He wants to prove that his car with a methanol fuel cell is better than any electric car with a large battery and charging cable. But politics and industry are so far not interested in Gumpert’s idea. Is it because you have agreed on battery-electric e-mobility and have invested billions in developing it? “Germany can only achieve the EU’s 2030 climate target with a high proportion of electric cars,” the Association of the Automotive Industry VDA shares BR policy magazine controversial on request with. All other options are “not available in ‘mass production’ until then”. Audi expresses itself similarly. The Ingolstadt-based carmaker did not even respond to Gumpert’s invitation to take a look at his concept. Compared to the BR explains a company spokesman: “Electromobility is by far the most efficient way to decarbonise and achieve CO2 fleet targets. Audi is therefore concentrating on battery-electric mobility.”

This is how the methanol fuel cell works With the drive concept, cars do not fill up with hydrogen, which is technically complex and expensive. Instead, a mixture of methanol and water is put into the tank. This is as uncomplicated and quick as possible with gasoline or diesel. This mixture is only heated and broken down into its components in the car itself. The oxygen and carbon dioxide escape into the air. Because climate-neutral methanol is used, there are no additional greenhouse gas emissions. The fuel cell converts the hydrogen from the methanol into electricity, which runs the electric motor.

For the first time, engineer Roland Gumpert implemented his drive concept in the Nathalie sports car – a two-seater coupé with 550 hp and a top speed of 300 kilometers per hour. The fuel cell produces enough electricity in the car to be able to travel at speeds of up to 130 kilometers per hour. If you want to drive faster, the battery supplies the electric motor with the additional energy required. If the speed drops below 130 km / h, the fuel cell not only supplies the driving current, but also recharges the battery at the same time. In this phase, the car drive needs less electricity than the fuel cell produces. If the vehicle comes to a complete stop, all the electricity from the methanol fuel cell flows into the battery.

If the battery is empty, the car can continue to drive, but at a maximum of 130 km / h – and as long as there is methanol in the tank. Gumpert specifies the range of the car as around 800 kilometers.

“The train left”

The Ulm management consultant Arnold Lamm also believes that the battery-electric car will prevail. “The train has left, you can’t stop it,” says Lamm. As an engineer, he worked for Daimler for more than twenty years. At the end of the 1990s, the Stuttgart-based car manufacturer opted for a drive with a methanol fuel cell, but the company did not achieve the breakthrough it had hoped for at the time. Lamm’s conclusion today: “Technically it works, but then as now I consider this system to be far too complex, too expensive and too time-consuming for a mass market.” Engineer Gumpert disagrees. His drive works: in the prototype of the “Nathalie” he built, a 400,000 euro super sports car that he plans to produce in a small series next year. And the same in an E-Smart that he has converted. His system is competitive: “We know for sure that we can get there with mass-produced products in terms of cost. Our system, including the battery, is ultimately no more expensive than a battery-powered car,” says Gumpert.

Advantages especially on long journeys?

Also from the point of view of the car expert Lamm, the technology “in this configuration is definitely worthwhile to be further promoted”. However, he sees opportunities above all in trucks that have to cover long distances. Here it could have advantages over pure hydrogen vehicles and electric trucks. So should the federal government be interested in e-cars with methanol fuel cells? At least Transport Minister Andreas Scheuer knows the concept. Gumpert was already in Berlin two years ago with his “Nathalie”. Scheuer seemed pleased. But does a 400,000 euro sports car really help in the fight against climate change? The minister sent engineer Gumpert back to Ingolstadt with homework: he was supposed to prove that his drive concept also worked in a small car.

Political tailwind for converted Smart?

In fact, Gumpert converted an E-Smart on behalf of the ministry. Since then, the car has driven 15,000 kilometers – without any problems, without a charging cable, just refueled with green methanol. However, all attempts to inform Scheuer about this failed for months. Emails from the company with the request to present the Smart in Berlin initially went unanswered. Upon request from Controversial said the ministry that methanol fuel cell systems were “not a mass-market solution”. In the meantime, the Federal Ministry of Transport has also contacted Gumpert. “We’re finally out of the drawer,” says the engineer. “We have been forgotten and apologized and will soon give us an appointment for a video conference.” So is the small company from Ingolstadt still getting some political tailwind? Engineer Gumpert continues to hope so. So far he has been pretty much alone with his vision of an electric car with a methanol fuel cell that can be refueled very easily and that continues to drive even with an empty battery.

There are many products that need to be charged when traveling or going out, so several charging heads will occupy a lot of backpack space. Even if it is used on a table, the bulky charging head is extremely unfriendly to the socket design. Obviously there are two socket positions, but often after one is plugged in, the other cannot be plugged in properly. I believe that many friends will have some adverse reactions to the picture below.

In response to the strong demand for small-size and high-power charging heads, GaN charging head technology emerged as the times require. Gallium nitride is an inorganic substance with the chemical formula GaN, a compound of nitrogen and gallium, and a direct bandgap semiconductor. For charging equipment, the biggest advantage is that while the charging equipment can maintain high power output, the volume of the equipment is further reduced.

The protagonist to be introduced today is the Aohi Magcube 30W fast charge charging head made using a new generation of gallium nitride GaN+ technology. Aohi may not be familiar to everyone, but in fact it is a smart brand under the listed company Aohai Technology, and Aohi Technology is the core manufacturer of original chargers for many domestic and foreign mobile phone brands such as Huawei, Xiaomi, OPPO, and vivo. Under such a strong R&D background, the products it launches are naturally worth looking forward to.

The product packaging is in a cool black design style, with a square flat outer box with the appearance of the charging head printed on it, and the overall packaging also highlights the characteristics of compactness.

It can be clearly seen from the specific output data on the back that this charging head can support a variety of output powers, including: 5V/3A, 9V/2.22A, 9V/2.77A, 15V/2A, 20V/1.5A or 3.3- 11V/3A, yes, the peak value can even output 33W high power in an instant. The focus is to support fast charging protocols for many devices, including Apple 2.4A, Samsung 5V/2A, Samsung AFC, QC2.0, QC3.0, QC4.0+, DCP, FCP, SCP, PD 2.0 and PD 3.0 protocols . Among them, the relatively rare 15V/2A, 20V/1.5A high-voltage charging in the mini charging head can have better charging power when charging large devices such as notebooks or tablets.

But of course, high-power fast charging such as Huawei, Xiaomi, OPPO, and vivo are basically proprietary protocols, and naturally they can only shake hands with the general PD or QC protocols.

The packaging inside the box is also very simple, just a charging head, manual and warranty card.

The volume control of the Aohi 30W fast charging head is indeed very good. The specific size is actually not much different from Apple’s previous “Five Fortune and One An” charging head, but the output power is properly 30W.

If compared with the 30W charging head of the MacBook Air and the 20W charging head of the iPhone, the gap is even more obvious.

In addition to excellent volume control, its own workmanship is also quite solid, and you can feel the feel of the thick and solid material when you pick it up. The shell has also reached a fire rating of 94V0. There is also a metal CNC cutting outer ring on the Type-C interface, which is not easy to deform after long-term plugging and unplugging. There are also finely carved patterns on the shell and even a charging status indicator. The workmanship design is indeed a lot of work.

The charging status indicator also corresponds to the three charging states (three-color LED lights). In the low current mode, it is a green light, the normal mode is a blue light, and the fast charge mode is an orange breathing light, which is very intuitive .

In fact, for most users, even if they know how many charging protocols it supports, it’s not as convincing as to test it on a real device directly, so the next step is to go directly to the test link (in order to trigger the fast charge normally, the remaining power of the following devices is 45 % Or less).

Test Samsung Galaxy S21 Ultra, successfully trigger Samsung’s 9V fast charge, the peak charging power is about 25W.

Recently, the newly launched OnePlus 9 Pro, because its Warp fast charge is a private charge pump protocol, so here is to trigger the PD charging, and it also has a power of about 18W.

The 65W fast charge of OPPO Find X3 Pro is also a private protocol, but it can also activate PD fast charge normally, and the peak power is about 17W.

Xiaomi Mi 11 Ultra successfully triggers PPS fast charge, and the charging power at this time is also about 25W.

And Xiaomi Mi 11 also supports triggering PPS fast charge. All Xiaomi Mi 11 series with this charging head can see the indication of fast charging in the charging interface.

Charging the Huawei Mate 40 Pro can normally trigger the PD charging power of about 12W.

The Meizu 18 Pro, which is more friendly to PD charging, successfully triggered a fast charging power of about 26W.

In some mobile power supplies that support PD fast charging, it can even support peak fast charging of about 21W, and the time to “return blood” to the mobile power can be effectively reduced.

Charging the iPhone 12 can trigger a fast charging power of up to 20W when the screen is turned on under low power. It can also meet the needs of fast charging while playing and charging, and the effect is very good.

The vivo mobile phones are not good for PD and QC high-power compatibility, and insist on their own private protocol, so the power of PD charging is still not high, which is mainly related to the mobile phone.

It can be seen that the Aohi Magcube 30W charging head has excellent PD or QC fast charging compatibility for most mobile phones. What about the charging support of tablets, laptops or handhelds?

When paired with iPad Pro, you can see that it can trigger the 15V high-voltage mode, basically running full 30W fast charge, and the effect is good.

On the MacBook Air, a large voltage of 15V is also triggered, which can reach a fast charge of about 30W. In such a comparison, the volume of Apple’s official 30W fast charging head is even larger.

Perform a charging test on Nintendo Switch, which can also reach about 16W, successfully triggering fast charging.

For some small devices, such as Bluetooth headsets, it also normally triggers the low current mode, which can effectively protect the battery of the small device.

After actual testing of various devices above, you should have a very intuitive understanding of the PD fast charge compatibility of Aohi Magcube 30W. In order to facilitate the collection of models, most of the above tests only choose newer devices. This does not mean that compatibility with older devices is not good. As long as the device in your hand can support fast charging such as 18W PD or PPS, then this charging head can provide a good fast charging experience.

In fact, the benefits of this ultra-mini GaN charging head are not only fast charging compatibility, but more importantly, it can effectively save desktop space.

Even if it is extremely extreme with the Aohi charging head plugged into the power strip, there is still space between the charging heads, and it will not encroach on the position of other charging plugs. This is also conducive to the heat dissipation of the charging head itself, and it is not necessary. Endure the random charging head on the desktop.

For example, in the company office scenario, the demand for fast charging of the device’s private protocol is not too great, and PD fast charging can be used by plugging it in. Except for some devices that do not support high-power PD, the others have already met the fast charging experience of about 18-30W, and the charging speed will naturally not feel slow.

Even if you need to bring a few more charging heads to go out, this small-sized GaN 30W charging head is also very friendly to backpacks and shoulders. It is compatible with most devices and ordinary 3A data lines, and the user’s use cost is relatively reduced.

Of course, this charging head is only 30W at the highest. The charging speed and power are definitely not as exaggerated as the 65W and 120W of some private agreements, and it is difficult to meet the high load demand of PD 65W and 100W notebooks. But in terms of its portability and the need to replenish power during idle time, this should be a product currently on the market that has the best experience in terms of charging power, support protocol and volume.

What’s more, it is really the only Aohi that can achieve 30W fast charging of GaN in this volume.

Aohi Magcube 30W has also launched a public test campaign on the tail public test platform. Those interested in the tail can actively participate in one, and users who have not won the lot can also jump to its official website to follow on our public test page. The latest price developments.
