Five small green circuit boards with Micro-USB ports and red green LEDs

JacobsParts Inc.

JacobsParts Inc. 5pcs TP4056 1A 18650 Micro-USB Charging Board

SKU CH-VN6M-VY65D

Five TP4056 modules charge 18650 and other 3.6 / 3.76 V lithium cells at 1 A from a 4.5-5.5 V Micro-USB or solder-pad input

  • TypeMicro-USB / Solder pads
  • Charges 18650 cells safely at up to 1A using TP4056 chip
  • Accepts 4.5–5.5V input via Micro-USB or solder pads
  • Red LED shows charging, green LED shows full at 4.2V
  • Compact 25x19x6mm board fits tight project enclosures
  • Thermal protection lowers current if input exceeds 5.5V to prevent overheating

Five-piece TP4056 charging module set

This pack contains five TP4056 boards that charge single 18650 cells or other 3.6 / 3.76 V lithium cells at up to 1 A. Each module accepts 4.5 to 5.5 V through a Micro-USB connector or solder pads and terminates at 4.2 V. Red and green LEDs show charging and full-charge status.

Suits hobbyists building single-cell power banks

Builders needing multi-cell balancing, charge currents above 1 A, or integrated protection circuits should look at different modules. The boards have no on-board cell holder, so a separate mechanical arrangement is required.

Thermal fold-back limits sustained current

When the input rises toward 5.2 or 5.5 V the chip automatically reduces charge current to protect itself, so extended sessions at the full 1 A rate depend on keeping the supply near 5 V and providing adequate airflow around the 25 x 19 mm PCB.

Questions about this item

What power source do I need to run the TP4056 board?

Connect a 4.5-5.5V supply through the Micro-USB port or the solder pads.

Can I charge 18650 cells that are rated for lower charge current?

The module delivers 1A; only use cells specified safe for 1A or more.

How do I know the cell is fully charged?

The green LED lights when the output reaches 4.2V, red while charging.
