3.7V 18650 Lithium-Ion Battery Charger – Universal Single Slot

The 3.7V 18650 Lithium-Ion Battery Charger is a compact and easy-to-use charger designed for charging compatible single-cell 18650 lithium-ion rechargeable batteries.

The 3.7V Lithium Ion Battery Charger operates from a wide AC 100–240V input, making it suitable for use with standard mains power supplies in India and other supported regions. It provides a 4.2V DC charging output with 500mA charging current, suitable for charging a single 3.7V nominal lithium-ion battery.

The spring-loaded single-slot design allows convenient insertion and removal of compatible cylindrical cells. A charging status indicator helps provide a visual indication of the charging process.

Its compact design makes it suitable for hobbyists, electronics users and anyone using rechargeable 18650 lithium-ion cells.

Important: This 4.2V 500mA Li-ion Charger is intended for compatible single-cell 3.6V/3.7V nominal lithium-ion batteries with a 4.2V charging voltage. Do not use it for battery packs, non-rechargeable cells, LiFePO₄ batteries, or other battery chemistries unless specifically confirmed compatible.
