Product Overview

This wall-mounted charger is designed to charge a single 3.7V 18650 Lithium-ion cell. It connects directly to your home's AC 220V wall outlet, eliminating the need for separate USB cables or power bricks. The spring-loaded cradle ensures a firm connection for both flat-top and button-top battery variants.

• Intelligent LED Indicator: The charger features a smart LED that turns Red during the charging process and switches to Green once the battery reaches its full 4.2V capacity.

• Auto-Cutoff Protection: To prevent overcharging and extend battery life, the charger automatically stops the current flow once the battery is fully charged.

• Spring-Loaded Cradle: The sliding terminal adjusts to the length of your battery, ensuring a secure fit for different brands of 18650 cells.
