Lithium Charger Booster Indicator - 5V - 2.1A

Our Lithium Charger Booster with Level Indicator and auto-shut-off Module combines a charging and protection circuit for a Lithium cell with 4.2V charging voltage.

The charging current and the booster output current are limited to 2.1A.

The charging level is indicated in 4 steps (25% to 100%).

As soon as a load is connected, the output will turn on. If the output current falls below 50mA for more than 30 seconds, the output will automatically turn off again. With the "Key" button the output can be turned on or off manually.

The Lithium Charger Booster with Level Indicator requires an input voltage of 4.5 to 5V.
