Hohm Tech Li-ion 4 Channel Battery Charger

4 channel USB-C charger Battery Length Detection: Automatically steps the output charge power up/down (determined by battery size). This can improve battery cycle life. 500mA (0.5A), 1000mA (1A), 2000mA (2A) is auto selected Input Power Regulator: Maximizes the power adapter capabilities up to 2A while simultaneously protecting USB ports and power. Auto Cut-Off: Stops charging once battery/cell reaches optimal 4.2V Low Voltage Activator: Stimulates li-ion batteries with low-voltage status. LEDs show the charging status of each cell Protection from short circuit, reverse polarity, overcharge, incompatible battery chemistry type (non Li-ion)
