4.2V 1A CHARGER FOR 1S LI-ION BATTERY

The 4.2V 1A charger is designed to charge 1S lithium-ion batteries, that is, batteries consisting of a single Li-ion cell.

It is suitable for compatible devices that use a single-cell rechargeable lithium-ion battery, including certain LED flashlights, headlamps, solar-powered lights, dive lights, small connected devices, and portable electronic equipment.

Its 4.0 x 1.35 mm output connector means it can only be used with devices equipped with the corresponding connector.
