Description
Hello. I am sharing my own power bank project that works on capacious 21700 lithium-ion cells. I assembled it on LG MT58 cells. The only more difficult thing is soldering the display to a vertical position. An efficient power bank module can be bought at a very good price on aliexpress. I own a Huawei phone and Fast charging works without a problem. I highly recommend this project! And good luck!
