Regarding enabling fast charging for smartphones: Smartphone fast charging protocols are categorized into public and proprietary standards. This mainboard uses a smart fast-charging chip that supports mainstream public fast-charging protocols on the market, meeting the fast-charging needs of various smartphone brands. Please confirm whether your phone supports public protocols before placing an order to avoid issues with fast charging!2. Regarding heat generation during charging: When the power bank is in operation, current flows through the mainboard and chips, and energy conversion results in some loss. This loss is dissipated as heat. During fast charging, the high power output causes more noticeable heat generation, which is a normal physical phenomenon. 3. The digital display may show inaccurate battery levels immediately after connecting the batteries. The battery meter supports a self-learning function for battery capacity and will display accurate readings after a few charge/discharge cycles.Package includeFast Charging Module *1
