Function of Efest LUC S2 Dual charger
Charging input: Pressing the button can change the charging modes(0.5A/1A/2A), it can charge different size 3.6V/3.7V Li-ion batteries.
0.5A can charge 2 pcs: 14500/14650/16340/16650/17650/17670/18350/18490/18500/18650/22650/25500/26650 batteries.
1A can charge 2 pcs: 16650/17650/17670/18350/18500/18650/22650/25500/26650 batteries.
2.0A can charger 2 pcs: 22650/25500/26650 batteries.
USB output: (1) Once connected to USB, it will get start to charge directly, 5V 1A USB output function can be used at the same time while batteries were charging on the LUC S2 charger. (2) Put the full charged battery to USB output channel if without wall adapter and connect electronic products with USB output port, then it will get start to charging. The USB function will be closed in 6 seconds without connecting devices.
Low power alarming: When discharging consumer electronics, the symbol of battery discharging will be flashing while the power of battery is lower than 15%, it means battery needs to be charged.
Built-in reverse polarity protection: While the charger is connected, each charging channel has reverse polarity protection, the charger screen stay blue and static to prevent from any short circuit, and batteries will not get harmful for reversing batteries.
Zero voltage activation function: when charger is standby, place overdischarging batteries (battery voltage is under 2.9V) to charging channel correctly,battery zero voltage activation starts, since battery overdischarging times, capacity and overdischarging degree is different, so the activation time will be different.
Over-charging protection & automatically monitor charging: Once the external power is connected with LUC S2 charger, charger will stop charging when batteries are full; if batteries were not taken off and the battery voltage will be lower than 4.0V because of many factors, charger will charge batteries automatically again. charger will start to charging if putting lower 4.18V batteries into LUC S2 charger.
