Customer Reviews

Based on 4 reviews
well built

I have an Uwell Nunchuku, and during the day i have to constantly swap out the batteries because it doesn't fully charge while i'm vaping on the other battery... but this is a small annoyance as it so well built, so much better than my last one! ie. the cord doesn't fall out every time i touch the thing, and the batteries slide in without hurting my fingers, etc
perhaps there is some setting i could change to charge the battery faster, i haven't read the wee book lol

If you vape you will need this

Always had the problem of running out of battery juice, as plugging may vape to charge was a struggle, this device is plug and charge basically, fast charging saves time. just what i needed

Quality Charger

Charges my 18650 LG h2 and Samsung batteries from dead to full in about 2.5 - 3 hours. Shows all stats while charging and has a cool night mode which dims the display. Very satisfied with this charger!


Je suis très satisfaite, ce chargeur est indispensable...
