Entering the era of fast charging of personal devices, the charging power has been increased, and the charging time has been shortened, which greatly improves the user experience and reduces the user’s endurance anxiety. However, what followed is that the size of the charger is getting bigger and bigger, and a 30W fast charging head is already half the size of a palm.
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.
