5 of 5 Great battery charger November 9, 2020
Reviewer: vaCsanady from ParkeDr, CO Uniteeecddd States  
This charger is replacing an older NITECORE charger that I owned. I thought the older model was great but this one is even slicker. Provides even more status while the batteries are charing. I love the fact that it has a USB instead of a typical AC power cord which makes it simple to use with either an AC outlet (using the proper adapter) or a battery bank. Would definitely purchase again!
