About as small as a lithium charger gets - little more than a USB-C socket with a charge IC behind it and solder pads for the cell. Plug in any USB-C lead and it runs the standard constant-current, constant-voltage cycle to 4.2V at up to 1A, then stops on its own. Use it when a full-size TP4056 board will not fit. It is a charger, not a protection board, so pair it with a protected cell or a separate BMS if the battery has none.
Key features
- USB-C input, charges one 3.7V Li-ion or LiPo cell
- Up to 1A charge current, 4.2V cut-off
- Automatic constant-current then constant-voltage cycle
- Barely larger than the USB-C socket itself
- Solder pads for the cell
- No protection circuit - use a protected cell or a BMS
