Now more and more high-power equipment needs to be powered, such as notebooks, high-power mobile power supplies, etc., but while charging these high-power devices, but also hope to use a charger to solve the problem of mobile phones, tablets and other electrical equipment, which requires a multi-port charger that supports high-power output to solve, the author today out of the box experience is the gallium nitride 140W fast charging charger launched by Aohi Ojai.
Unboxing introduction
Aohi Ojai gallium nitride 140W charger packaging is packaged in gray-yellow contrast, with product pictures on the front, PD 140W written on the right side, and the logo of 2C1A three interfaces in the lower right corner.
The upper part of the back is a schematic diagram in the case of full insertion, the middle is the detailed parameters of the Aohi Ojai gallium nitride 140W charger, and the following part is all in English, which is also very good for the international market.
The sticker is torn off on the side, and the magnetic opening method is adopted, and when opened, you will see a thick protective paper, and there is a display picture on the left.
Remove the protective paper, and below is a family portrait, the charger wrapped in a protective bag, stuck in custom black foam, and the instruction manual and warranty card.
The charger body is yellow throughout, using foldable pins to further reduce the carrying volume, the plastic material of the shell has a skin-friendly feel, it is very comfortable to use, I can't help but want to touch more, and all connections are treated with rounded corners to further enhance the feel.
The front side only has the AOHI English logo, and the back is also very simple, only 140W gallium nitride.
There is a widened design on both sides of the prong, in order to improve the safety of use, the detailed parameters of the charger are on the right:
Model: AOC-C012;
输入：100-240V~ 50/60Hz 3A Max；
PD输出:5V=3A、9V=3A、12V=3A、15V=3A,20V=5A、28V=5A;
PPS 3.3-21V=5A 140W Max Each Port；
USB输出:5V=3A、9V=2A、12V=1.5A、10V=2.25A、11V=3A 33W Max;
Total output: 140W Max;
The status of passing various certifications is also marked.
The black front panel is made of three-dimensional micro-engraved diamond pattern, which is also the unique IP of the AOHi MagCube fast charging family, which looks very delicate and can also speed up the heat dissipation effect. The three-color breathing indicator strip is integrated on the top, and the yellow breathing light is high-power fast charging, blue is normal charging, and green is fully charged, and the charging status of the device is clear at a glance.
The actual measurement of the dimensions is 69×73×31.8mm (with errors), which is small compared to other 140W output chargers, weighing about 306g, and full of weight. And the charger uses Apple's same gallium nitride chip (PI chip), which is 28.54% smaller than Apple's 140W charging head, which is a good choice for users with high-power input needs.
Protocol testing
AOHI GaN 140w charger is the first to support UFCS fast charging protocol, compatible with PD3.1/PD3.0/QC/PPS multiple fast charging protocols. The charger adopts a three-port output configuration, and both USB-C interfaces support 140W fast charging output, not only supports Apple 2.4A, Samsung 5V/2A, QC3.0/2.0, QC4+ and other mainstream protocols, but also PPS protocol with 5V3A / 9V3A / 12V3A / 15V3A / 20V5A / 28V5A six fixed voltage levels, and supports 3.3-21V5A a set of dynamic protocols, USB-A port supports Apple 2.4A, Samsung 5V/ 2A, QC3.0/2.0, AFC, FCP, DCP 1.5A, MTK-PE, SCP and other protocols, compatible with UFCS, PD3.1, PD3.0, PPS, QC and other fast charging protocols, can provide fast charging for many devices on the market.
Actual charging test
As a charger with three output ports, the output power of multiple ports has to be concerned, and the powerful thing is that the charger has an intelligent power adjustment function, supporting single-port 140W (USB-C)/33W (USB-A), multi-port 65W+65W, 100W+33W, 65W+40W+33W and other power distribution strategies, and multiple devices can enjoy fast charging. In this way, you only need to take it with you when you go out to charge multiple devices at the same time, and this multi-port charger makes the desktop more simple and beautiful even when used at home.
USB-C1 port and USB-C2 port have the same output efficiency, which is difficult for many multi-port charging equipment to do, and Aohi Ojai gallium nitride 140W charger perfectly supports, to support 60W input mobile power supply, directly recognize PD3.1 100W protocol, full speed replenishment.
Charging the power bank with the USB-A port is also directly reaching the full speed of the power bank recognition QC2.0 protocol.
Double-port load under testing, basically the power is directly full, you can see that the following mobile power supply can also be charged with 15W power when it is 100% power, the above mobile power supply is recognized as PD3.0 60W gear, but also in line with the protocol allocation when the double C port is powered at the same time.
Summary: Aohi Ojai gallium nitride 140W charger can be said to be a small and powerful charger, compatible quite well in power and size, 140W output power can make your laptop, mobile phone, tablet and other devices quickly fully charged; AOHI Ojai gallium nitride 140w charger also took the lead in supporting UFCS fast charging protocol, compatible with PD3.1/PD3.0/QC/PPS a variety of fast charging protocols, whether it is notebooks, mobile phones, tablets, game consoles and other devices, can be charged at the same time, and the power distribution of three ports can be achieved without slowing down, in addition, the matrix heat dissipation structure of the product is also particularly good, it can help heat dissipation more efficient, so as to make charging safer; The design of the breathing lamp is also a highlight, can check the charging status of the equipment at any time, eliminating the step of observing power with the instrument, greatly saving charging time, I have to say, high-power charger is the final destination of multi-device users.
