Charge multiple 18650 Li-ion batteries at once with this independent-slot USB charger — each slot charges separately for safe, efficient charging.
1 × USB Li-ion Battery Charger
Charging is very simple. When charging, 1 battery provides a current of up to 0.45A maximum (5V 0.45A at the input from the network via USB). If there are 2 batteries, then only 0.3A per battery (5V 0.7A from the mains). 3 batteries are being charged with a current of up to 0.23A each (5V 0.85A from the mains). And if there are 4 batteries, then each will receive only up to 0.18A (from a 5V 1A power supply).
When charging, the LED lights up red. When the charge is complete - green. The empty slots also light up green. It doesn't heat up. Charges the battery to 4.19...4.20V.
It is a very basic charger. When charging a single battery, it delivers a maximum current of 0.45A (drawing 5V/0.45A from the USB power source). With two batteries, each receives only 0.3A (drawing 5V/0.7A). Three batteries charge at up to 0.23A each (drawing 5V/0.85A). If four batteries are inserted, each receives only up to 0.18A (drawing 5V/1A). The LED glows red while charging and turns green when charging is complete. Empty slots also show a green light. It does not overheat. It charges batteries to 4.19–4.20V.
