LUC V4 May 18, 2019
Reviewer: Eric from Schenectady, NY United States  
Love the 2 amp capability for 18650! It charged 2 18650’s from dead to full in 2 hours and 15 mins. Highly recommended. Btw it’s perfectly safe to charge quality batteries at 2 amps. Been doing it for years with other devices without harm to the batteries

Reviewer: Mallory D. from St Louis, MO United States  
This charger works great and was well worth the price. I love that it shows the battery level for each of the four slots and I've never owned a charger that charged more than two at once.. This feels life changing lol
