Very good charger, it charged a Huawei phone and a Samsung tablet very quickly.
It supports fast charging.
It has a metal frame and does not heat up.
It fits very well into the car's lighter.
Its display shows in order first the car's Volts, then the Volts of the USB ports, and then the consumption of the USB devices in amperes, and this happens cyclically. e.g.: 14.0v - 5v - 1.7A.
On the downside, the display does not have high brightness, but this is not a problem for me.
