Summary of ChargerLAB

The ANKER 65W 3-in-1 GaN charger has a fire-retardant rounded case. The foldable prongs it comes with make it easy to carry. Both USB-C ports can support up to 65W and the USB-A port can also support fast charging.

After taking it apart, we found it adopts two independent buck circuits to achieve three-port fast charging and automatic power distribution. It also has a fixed output voltage. The PCBA module and the gaps are filled with pounding compound for heat dissipation. It is commendable that it can achieve a charging power of 65W in such a small size, and it even has three ports.
