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 connector 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 be flashing in blue while the power of battery is lower than 15%, it means 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 prevent from any short circuit.
4. Zero voltage activation function: when charger is standby, place over-discharging batteries (battery voltage is under 2V) to charging channel correctly, battery zero voltage activation starts, since battery over-discharging times, capacity and over-discharging degree is different, so the activation time will be different, and red light will turn on after battery activation.
5. Over-charging protection & automatically monitor charging: Once the external power is connected with LUC V4 charger, charger will stop charging when batteries are full; if batteries were not taken off and the battery voltage will be lower than 3.9V because of many factors, charger will charge batteries automatically again. charger will start to charging if putting lower 4.18V batteries into LUC V4 charger.

    I managed to break my charger two days before I was due to fly to Sicily on holiday. Panic! I shouldn’t have worried though, Custom Vapes said they had stock of the Luc 4 and if ordered before 2pm it would be here next day. Order placed and Charger here in time for the holiday. Haven’t really used it that much as only got back last night but it has a lot of features and even on the 0.5 amp charging rate seem much quicker that my old Nitecore charger.

    Well what can I say about the LUC V4…

    Firstly it’s built beautifully. Screams quality/high-end product. Not heavy but beautifully made.

    The springs are stiff on the battery drawers. But that’s a good thing, batteries and good connections (especially with vaping) are an absolute must. Also because it’s a brand new product I thought it would be a good idea to put a little dab of Deoxit Gold G100 contact enhancer on the contacts which I did. Batteries love Deoxit.

    Charging performance it top notch – charges my new Sony VTC5A’s I bought for my regulated mods absolutely as well as can be expected. Very functional charger which gives you the opportunity to charge at the different voltages/speeds. I recommend the lower voltages however for new battery longevity however. But regardless of which mode you choose this is a pretty darned quick charger regardless !.

    Also very impressed with how quickly Custom Vapes dispatched my order and how quickly it arrived. Considering the time of purchase was over the Xmas and New Year festivities !.

    They truly are a high end vape company and sell very high end products. I should say my head is being turned by some of the beautiful, high quality mechanical mods they have for sale here… I love all types of vaping including mechanical tubular and will probably treat myself to a new one, one day from here along with a few of the crazy pink HB6’s to fire it 🙂

    Kind Regards and a Happy New Year,

    Stuart Todd from Dunfermline
