  1. Not great but not terrible 3 Star Review

    Posted by on Jan 12th 2020

    It does charge batteries fairly quickly but not the best charger out there. Does the job.

  2. Good Charger 5 Star Review

    Everything you will need and nothing you don't to safely & quickly charge a very wide range (not just 18650's) of battery types/sizes. There are better chargers out there, but at many times the price of this one. At this price point, when comparing apples to apples, i'd say its probably the best charger I've ever used! thanks once again CV! you guys are the best!
