The micro micro port installed in the device was deformed. It had to be adjusted to connect the charging cable. Then there were no more problems, it works fine.

lombaig After 2 weeks of use, the charge control IC (57b0, also known as TO4057) became damaged and shorted. From this, both sides of the red-green LED burned out. Fortunately, the other circuits remained intact. Unfortunately, I didn’t find such an IC on Banggood, but I was able to order from eBay. Instead of a dual LED, I installed two different colored LEDs and also replaced the micro USB charging connector with an intact one. The instrument works well again.
It has also proven to be a microelectric development game.
