Compared with competing products on the market, its biggest feature is that each interface can support high-power fast charging of more than 100W, and the performance is quite impressive.

As an Apple-exclusive version, the only compatible protocol is PD fast charging. However, compared with Apple's original 140W GaN fast charging, it has advantages in size, number of ports, and performance. It is very suitable for Apple multi-device users to purchase and is suitable for daily home office and travel use.

After taking it apart, we found it uses PFC+AHB power architecture design. In addition, the PCBA module is filled with potting compound to improve heat dissipation, and heat sinks are added to the bridge rectifier, PFC boost inductor, and even the shell to help dissipate heat. Whether it is the overall or the details, the materials and workmanship of this product by Anker are quite good.
