preface
In recent years, gallium nitride chargers have received widespread attention as a hot topic. As a third-generation semiconductor material, GaN chargers offer many advantages, such as small size, high power density, excellent heat resistance, and so on. In this competitive market, Aohi Ojai GaN charger continues to break through in continuous efforts, and has carried out a series of optimizations and improvements on the basis of previous products, bringing us a charging head that supports the highest 140W peak, and has three interfaces of 2C1A, which solves the limitations of the previous product in the maximum output power, provides users with more powerful charging capacity and speed, and meets the needs of users for charging a variety of devices. Let's feel the charm of Aohi Ojai 140W GaN charger head!
Unboxing
The packaging of this Ojai 140W gallium nitride charger still continues the consistent simple and eye-catching style of AOHi, with a bright combination of gray and yellow, plus a yellow logo, and a physical picture of the charging head with yellow and black, the visual impact is quite strong.
The back is printed with a promotional picture of the use of the charging head, which can charge the mobile phone, tablet, and laptop at the same time, and the charging output and input parameters of the charging head are pasted in the middle, as well as some specific information of the manufacturer.
Opening the package, we come to a family portrait of the product, in addition to the charging head, there is a plastic sticker, a warranty card, an instruction manual.
Detail experience
AOHI Ojai 140W gallium nitride charger with yellow coating, very eye-catching, the shell is PC material, the overall style is consistent with AOHi series chargers, the four corners are rounded transitions, and the front center is printed with AOHi's brand logo, so that the product has a certain degree of recognition.
The back of the charging head is printed with the main selling point of the 140W GAN+.
The output panel part, like other products in the same series, is designed with a three-dimensional micro-engraved diamond pattern, equipped with two USB-C charging ports, and a USB-A interface, and the interior adopts a yellow rubber core, which is more eye-catching with the black shell. There is also an LED indicator at the top of the output panel, which can display three colors, namely yellow (fast charge), blue (normal charge), and green (microcurrent), to correspond to the current charging status of the device.
I have used several chargers that support 100W fast charging before, but they are larger than this Ojai's 140W fast charge head in terms of weight and volume, and it seems that in order to achieve high power charging, portability must be compromised. However, to my surprise, AOHi's 100W GaN fast charging charger is very small. Its plug part adopts a foldable design, which can be stored inside the fuselage when not in use, further reducing the volume of the fuselage.
The output supports 5V3A, 9V3A, 12V3A, 15V3A, 20V5A, 3.3-21V 5A, the maximum single C port output power is 140W, the USB-A port is 33W, and the power of the double C port is 65W at the same time. By reading the parameters, users can understand the charger performance more intuitively, so as to better use.
As a 140W three-port charger, the size of the Aohi Ojai 140W gallium nitride fast charging head is only 73mm× 68.5mm× 31.5mm, and the weight is only 306 grams. Compared with the 140W charging head of Apple laptops, the volume is 28.54% smaller, so it is also more suitable for carrying.
Usage experience
Let's actually test it to see how efficient the charging is! Through the introduction, we can know that Aohi 140W charger takes the lead in supporting UFCS fast charging protocol, super fusion, any device can achieve fast charging, compatible with PD3.1/PD3.0/QC/PPS a variety of fast charging protocols, can charge notebooks, mobile phones, tablets, game consoles, smart watches and other devices at the same time, and intelligently distribute charging power, the maximum power of a single C port reaches 140W.
The safety of the charger, especially the safety of the fast charging charger, I believe that everyone is most concerned, Aohi 140W charger gallium nitride charger has five protection mechanisms, namely overvoltage protection, overcurrent protection, overpower protection, overtemperature protection, anti-interference protection, so that we can be more at ease when using.
Because there is no Apple laptop around the author, so charging a device that supports a maximum of 65W input power, you can see that the voltage is 19.9V, the current is 3.04A, and the power reaches 60.67W, which basically reaches the maximum input power of this device.
Below we use the C port to charge the iPhone 14 pro max, the battery is still 15% left, from the figure below you can see that when charging with the C port alone, the voltage is 8.98V, the current is 2.95A, the charging power reaches 26.49W, the indicator light shows orange, enters the fast charging mode, and basically has run the maximum input power of the mobile phone.
When charging a mobile phone with 75% of the charge, because it is close to full charge, the indicator light of the charging head turns blue, and the charging head enters the normal charging mode, with a voltage of 5.15V, a current of 1.57A, and a power of 8.08W.
Finally, use two C ports to charge at the same time, the maximum input power of one device is 65W, and the maximum input power of iPhone 14 Pro Max is 30W, you can see that when charging at the same time, the indicator shows orange, the power reaches 92.94W, and the charging head has run full of the maximum input power of the two devices.
summary
After this period of experience and use, the Aohi Ojai 140W gallium nitride fast charging head really surprised me. First of all, this charging head uses gallium nitride material, which means it has a lower operating temperature, which greatly enhances safety and stability. At the same time, the charging head adopts UFCS fast charging protocol, which has strong compatibility. Whether it's a phone or a computer, it's capable of providing fast charging for a wide range of devices with ease. Moreover, this charging head is designed with folding pins, easy to carry and store, in addition, two C ports and one A port have a total of three interfaces, and the single C port supports a maximum of 140W fast charging, which can charge three devices at the same time, which greatly facilitates my use. To sum up, the Aohi Ojai 140W GaN charger head is an excellent product. It not only has excellent charging speed and stable performance, but also portability and strong compatibility. Whether in terms of quality or experience, this charging head can bring you absolute peace of mind and satisfaction.
