22.5W USB Power Bank Module for 3.7V Lithium Cells

Build a power bank around your own cells with this USB charging module for compatible 3.7V ternary lithium cells. It is for electronics makers who can solder the battery connections.

• ✅ Read charge information at a glance — The TFT screen shows power, voltage and temperature.
• ✅ Reuse the USB-C connection — Charge the build or power a device through the same port.
• ✅ Connect existing USB leads — Two USB output ports give you extra connection options.
• ✅ Match charging to your device — The module works with several fast-charge protocols.

USB-C works in both directions. Fast charging depends on the connected device and protocol, and is unavailable when several ports are in use at once.

Plan the installation around compatible cells and the module dimensions. Battery connections require soldering, and cells are supplied separately.
