TP4056 1A 18650 Li-ion Charger Module (3.7V/4.2V) with Protection

The TP4056 1A lithium battery charging board is a compact, reliable charger module designed for single-cell 3.7V/3.6V Li-ion batteries such as 18650 cells. It charges up to 4.2V and includes protection features (on protection versions) to help prevent overcharge, overdischarge and overcurrent—making it a go-to choice for DIY power banks, portable electronics, IoT builds and robotics projects in Ghana.

Key benefits

• Safe 1A charging for single-cell 18650 Li-ion batteries

• Charges Li-ion batteries to 4.2V (full charge)

• Protection helps reduce battery damage and improves reliability

• Perfect for DIY power packs, robotics, Arduino/ESP32 portable builds and STEM projects

Typical applications

• 18650 power bank builds and rechargeable battery packs (single cell)

• IoT devices powered by 18650 (ESP32/ESP8266 with regulator)

• Robotics projects needing a rechargeable power source

• DIY portable electronics, LED projects and test rigs

How it works (simple)

• Supply 5V input to the TP4056 charging board

• Connect a single 3.7V/3.6V Li-ion battery (18650)

• The board charges the cell and stops at full charge (4.2V)

• Status LEDs show charging / full (varies by version)

Important notes

• Designed for single-cell (1S) Li-ion only

• Use a quality 5V supply and good wiring for stable 1A charging

• If your project needs 5V output, use a boost converter after the battery

Package includes

• 1 × TP4056 1A 18650 lithium battery charging board (with protection)
