Most portable projects are now using LiPoly battery technology, but it requires a more finicky method of charging. This TP4056-based module makes it trivial to add a dedicated single-cell charger to your project, powered by any USB-C power source. Note, this USB chip is dumb, so it won't poll the USB supply for higher voltages/current capabilities.


  • Single-cell charger for Lithium chemistry cells
  • Preset for 1000mA, but is configurable down to 30mA by resistor change
  • USB-C interface
  • LED indicators


  • NanJing Top Power ASIC TP4056A Standalone Li-Ion charger
  • 4.5~5.5V VDC input
  • 25x19mm (1x0.75")

Note: In default configuration, this charger will pull as much as 3.7W from a USB port, which are nominally rated 2.5W on a standard PC. Make sure you use a USB charger or powered USB hub.

Cells are becoming very tolerant of high-current charging, but for the best battery life, use the 1/3 rule of thumb. A 1000mAh cell is best treated by charging at approximately 300mA
