Review on Xiaomi 70mai Jump Starter Midrive PS01 by Dimitar Kuzmanov ᠌

I accidentally reversed the polarity. The device closed, began to warm up and burn out its charge. It got hot until the battery was completely dead. Charged. It still works fine. Has some pros: Stylish device. Started up a dead car, inline four Temperature near zero Cons below: I didn't quite understand how it all works. The instructions seem to be exhaustive, but I had to poke around. If the battery is completely dead, it does not understand where it was connected and what they want from it.
