The single-bay F1 Li-Ion Battery/USB Charger from Nitecore provides an all-in-one charging solution for many commonly-used cylindrical rechargeable batteries. Ideal for use on the go, you may use solar panels or any 5V USB source for power. It is compatible with lithium-ion and IMR 26650, 18650, 17670, 18490, 17500, 17335, 16340 (RCR123), 14500, and 10440 batteries. The base automatically detects the needs of each battery inserted and determines the correct charge for it. When a charged battery is inserted in the unit, it can function as a power bank, transferring power to another USB device.
Additionally, it will set the charging mode to optimize the battery charge: constant voltage, constant current, or trickle-charge. Power and charging status LEDs clearly show the progress of each battery, and over-charge protection circuitry cuts the charging current to prevent damage to the battery. Gold-plated contacts help increase power transfer and reduce corrosion.
Automatic Mode Selection
Circuitry automatically detects the size, chemistry, and capacity of each battery inserted
Determines the correct amount of voltage and current for each type
Sets type of charge from constant current, constant voltage, or trickle-charge, depending on the needs of each battery
Over-charge protection prevents damage to battery by automatically stopping current when battery reaches capacity
Turns off power bank output when source battery goes below 3.3V
