Changed review from 1 star to 4. I disassembled, removed the battery, pushed it with the help of a laboratory power supply. I put it on charge, it accepts a charge. In general, I restored the device, along the way I found ways to upgrade the battery. Returning the device would cost me half its cost plus half a day of travel. My choice is conscious, but I advise you to return such immediately, reddit is full of stories about dead batteries when buying these devices! But I hope it helped. I'll make a repair video later.

To complement my review, I have added some photos to illustrate the product.
