I owned a Luc V4 and it worked well for about 5 years before the display packed in. More than happy to update with the new version, full confidence in the charger itself, has all the safety features you'd expect, so I'm perfectly happy to recommend it. The display turns off while charging though to save energy unlike the older version, may be quite easy to forget you have batteries on charge if it's not lit up. Might just be me though.
Very happy with this charger - particularly like the simplicity and detail in the display. Vaping 101 also delivered very quickly.
Nice, good looking charger with lot of power 0.5A - 2A (2A for 2 batteries 0.5 - 1A for 4 batteries)
Some people might miss discharging function for older battery types (with memory effect)
I’m very satisfied tho.
Having had my Luc V6 for quite a while, and having no issues with it, I needed a new charger for 21700 batteries and found this new Luc v4 elite on the site. It's brilliant, nice clear display, with adjustable charge rate, fits 2 21700's easily and at a good price.
