  4. Great charger Great charger

    What can I really say. Charges my batteries indescribably fast and works great. Since I can charge four batteries at one I'm never without charged batteries.

  5. Exceptional Charger Exceptional Charger

    This is the newer version of the LUC V4 charger and it works great. It charges batteries like it's supposed to, and it has an excellent look and quality built feel.

    One feature I have not used yet but which I am excited to have is the USB charging port. That is sure to come in handy at some point.

    Some retailers are still selling the older version which has a different LCD display. The older one is not as visually appealing, and from their websites it's hard to tell which retailers are selling the new ones or not. Rest assured, just like the picture, this is the new model (2014)

  6. Smart! Smart!

    Posted by michael koczan on 24th May 2014

    Batteries can be dangerous! That is why I like a charger that gets Me out of 'The Loop' when it comes to proper settings and such. This critter does that and the indicator is clear. It is so smart! Love it!

  7. Fast Charger!!! Fast Charger!!!

    Posted by Jim Ketchum on 14th May 2014

    I was surprised how fast this cjarges batteries, it will charge 4 batteries in under an hour!!! Doesn't get any better than that!!! :)

    great charger, the screen is different in the picture, what you actually get is better so thats a plus, easy to use, fast charging, little more expensive than another vender i know but i was ordering a bunch of stuff from here so it would have equaled out after the extra shipping cost so i went ahead and got it here
