Single Slot Battery Charger for 3.7 Volt Lithium Ion Cells
This is a single slot battery charger 3.7 volt lithium ion cells. This charger is meant to accommodate cells from 30 mm to 67 mm in length so it should work with almost all 3.7 volt cylindrical cells in sizes 16340, 18350, 14500, 14650, 18500, 18650 and 22650.
Even though this charger is designed to stop supplying current to the cells once the cell is fully charged, do not charge cell unattended and do not leave them charging overnight.
This charger has a US plug and requires 100 to 240 volts AC at 50 to 60 hz to operate. Be advised that we source these chargers from multiple manufacturers. They may look different from the pictures above but will meet or exceed an output specification of 3.7 volts DC at 300 milliamps with automatic shutoff.
