Introduction

Anker previously launched a 140W four-port GaN charger. Recently, the series welcomed a new 100W model, featuring two USB-C and one USB-A port. The two USB-C ports support 100W fast charging, and all three ports support intelligent power distribution. It supports Xiaomi's 90W proprietary protocol, with both USB-C ports capable of delivering a maximum output of 90W for Xiaomi phones and tablets.

It is equipped with a screen that can display the power of all three ports. Through touch button operation, users can rotate the screen orientation, switch the displayed power, and show the charger’s temperature, making it convenient to monitor device status. It can also record the charger's usage time and comes with an 18-month warranty.
