When charger switched on… all four led lights get on and not blinking. If i connect the power bank to my phone it is not charging.. what is the solution
Hello. I had the same problem. After opening up my Xiaomi 20000mah power bank, I discovered that the positive terminal to the battery on the regulator (circuit board) was disconnected. Simply soldering the two pads together should fix your problem. I also have some pictures of the connected terminal and the solder fix Connected Terminal Solder Fix Hope this helps.
Noting to be worry about. Just press the power button for more than 15 secs and see the magic…✌
