Ten small green circuit boards with Type-C ports and charging chips

KEHIPI

KEHIPI TP4057 1A Li-ion charger board Type-C USB 10PCS

SKU CH-9EAW-EY1GC

Ten USB-C boards charge 3.7 V lithium cells at up to 1 A with over-voltage, over-discharge and over-current protection

  • ColorTP4057 Type-C USB 10PCS
  • Charges 3.7 V lithium cells via USB-C
  • 10 boards in one pack for multiple projects
  • TP4057 controller stops at 100 mA tail current
  • Built-in protection against over-voltage, over-discharge and over-current
  • Pre-charge activates below 2.9 V for deep-discharged cells

10-piece TP4057 Type-C USB charger boards

This pack contains ten TP4057 modules that charge single-cell 3.7 V lithium-ion batteries from a USB Type-C source. Each board integrates over-voltage, over-discharge and over-current protection and terminates the cycle automatically when the current falls to 100 mA.

Makers adding USB-C charging to 3.7 V cells

Suits hobbyists building portable devices, repairing tablets or upgrading 18650 packs who want a protected, drop-in charging solution with Type-C input. Not for engineers who need adjustable charge currents, multi-cell balancing or higher than 1 A throughput.

1 A maximum charge current with 4 A protection trip

The TP4057 IC limits the charge current to 1 A and the onboard protection MOSFET disconnects the load at 4 A over-current. This single figure decides whether the board can power your target application safely.

Questions about this item

What happens when the 1 A charging current drops to 100 mA?

The charging cycle terminates automatically once the current falls to 100 mA after the 4.2 V float voltage is reached.

How much heat or noise does the board produce during continuous charging?

The module has no fan or active cooling; it runs silently and warm only under the 1 A charge current.

Which battery cells must I already have to use these boards?

Any 3.7 V lithium cell such as an 18650 or composite pack that fits the 4.2 V charge profile.
