Features:
1. Charging input: Pressing the rectangle button can change the charging modes(0.5A/1A/2A) and charge different size 3.6V/3.7V Li-ion batteries.
- USB output: DC5V 1A USB output connectors are compatible with most portable consumer electronics.
- 0.5A/1A can charge 4pcs: 10440/14500/14650/16340/16650/17650/17670/17350/18490/18500/18650/22650
- 2A can charge 2pcs : 25500 and 26650 batteries
2. Low power alarming: when discharging consumer electronics, the transparent button will flash in blue when the battery’s power is lower than 15%, which means the battery needs to be charged.
3. Built-in reverse polarity protection: While the charger is connected, each charging channel has reverse polarity protection; the charging light is still green and prevents any short circuit.
4. Zero voltage activation function: when the charger is on standby, place over-discharging batteries (battery voltage is under 2V) to the charging channel correctly; battery zero voltage activation starts since battery over-discharging times, capacity, and over-discharging degree is different so that the activation time will be different, and the red light will turn on after battery activation.
5. Over-charging protection & automatically monitor charging: Once the external power is connected with the LUC V4 charger, the charger will stop charging when the batteries are full; if batteries are not taken off, and the battery voltage will be lower than 3.9V because of many factors, the charger will charge batteries automatically again. The charger will start charging if putting lower 4.18V batteries into the LUC V4 charger.
6. 1 Amp Portable USB Output: The charger can charge most USB devices, such as mobile phones, iPad, MP3s, Mp4, PSPs etc. To do so, insert a fully charged battery into channel 2 of the charger, disconnect the AC wall plug and hold the rectangle button for 2 seconds.

Overall I’m very happy with the Luc V4. It has a very nice display that clearly indicates what the charger is currently doing and the state of charge on the batteries connected. The spring loaded sliding battery connectors hold batteries quite firmly, they are pretty securely held in place.
My one gripe would be the molded plastic base, it’s fairly awful. It has a slight bowl shape, so if you disconnect the power supply you could spin this thing like a top. It’s not an inexpensive device, and at this price point I’m sure they could have included some rubber feet to stop it from sliding around like a hockey puck. I still recommend it though, just plan on supplying your own stick on footers for it.
