YZXStudio 8 Power Bank Review (4x18650) - #29 by will34

Shipping on the PLX Legion is a bit more than ususal, but this device has been the first powerbank with OLED. And also multiprocessor (temperature, voltage, current, etc.).
It’s currently in the selling out phase, the black one and the smaller 5.500mAh capacity already sold out.

It’s also availiable on eBay:
