Review on Charger PATRIOT BCI-4D black by Wiktor Lipski ᠌

It worked for exactly five minutes, then it clicked inside and everything, instead of the battery charge, shows an incomprehensible voltage value that changes periodically, after another five minutes the battery icon lights up and the screen starts blinking. I tried to treat for the sake of experiment and a complete review. A couple of times I disassembled and looked through and soldered all suspicious places. Enough for one charge, after again an incomprehensible pandemonium with numbers and blinking of the screen. It is treated with cotton on the body, after that it seems to work. Looks like there is some cold soldering somewhere. In general, the operation of this device resembles a tube TV, for those who understand)
