Smaller really makes sense! Inexpensive Anker GaN charger recommended

December 23,2019

From chargers, data cables, to mobile power, this Anker GaN USB-C single-port charger should be my fifth Anker product. The main reason to pay attention to it is GaN technology! Major brands are emphasizing the revolutionary

improvement of GaN and breakthrough technological innovation. Anyway, it makes people feel that GaN is very strong, as if it can change and completely change the battery industry. In fact, it's not so god, the power is still so high, but the size is indeed smaller, a lot smaller!
In this article, I will share the evaluation of Anker 60W single C port charger and compare it with several other chargers that I have used. The product comes from the technical aesthetics of everyone:
To understand why GaN can bring fundamental changes to the charger industry, you must first understand the charging principle. If you don't want to read the text, you can refer to this video produced by Aifu, 1 minute 10 seconds to 2 minutes 45 seconds. Basically, the question of whether GaN is good or not is very clear. Not professional, but definitely understandable. It also designed some knowledge of the GaN material itself, which I will not repeat.

The charging process is that the charger integrates 220V AC power into low voltage, low current, and DC power suitable for mobile products. In the middle, a switch-like structure is used to continuously switch on and off. As a result, a constant magnetic field is generated outside the coil on the left side of the above figure. According to various principles of Maxwell and other great physicists, the corresponding induced voltage will appear on the coil on the right side (secondary winding) and Transform into the current and voltage suitable for mobile phones, and then you can charge.

Want to improve the efficiency of charging, that is, to increase the induced electromotive force induced by the right coil. The change in magnetic flux is the root cause of electromagnetic induction! Only the continuously changing magnetic flux on the left side can induce induced emf! The larger the magnetic flux change △ φ, the stronger the induced electromotive force on the right! Therefore, it is necessary to increase the "operating frequency of the on-off switch" as much as possible. The previous flyback topology of semiconductor silicon materials can achieve a switching frequency of 100kHz, and it will generate severe heat even if it is higher. However, the gallium nitride material can reduce the volume while increasing the operating frequency. This is why GaN chargers are so powerful.

Out of the box appearance:
Back to the product itself, this PowerPort Atom III is already Anker's Nth GaN charger. Simply look at the specifications, single USB-C design, power 60W, support PowerIQ 3.0 fast charge.
Also evaluated this time is Anker's c-c charging cable. The quality of the cable is good, it feels a bit rougher than the original Apple, and it should be durable.
In terms of design, the gray logo, blue charging indicator, blue iq logo, and whole body white. Overall, it looks better.
The first feeling is that it is lighter and smaller than the original one! Anker PowerPort Atom III weighs 132 grams. The whole is very light.
So this is more suitable for users using Qualcomm and PD mobile phones and PD notebooks. Other agreements are not suitable for this product.
