The best 2 bay charger out there PERIOD. May 26, 2019
Reviewer: Matt from Glen Allen, VA United States  
I have more battery chargers than I care to admit.  I use my chargers for everything from AAA to 21700. It's that last one that has always given me problems. Until I came across the UMS series from Nitecore that is, every other charger I have hits a hard stop on the spring loaded battery bay when inserting a 21700 and you basically have to force it down while risking the integrity of the outer wrapping.  This isn't the case with the UMS series.  There's about half an inch of additional play in the spring loaded bay which makes inserting and removing these larger batteries sooo much easier.

Couple that with the clear and informative display and you've got yourself one of the most versitile chargers on the market. Oh and not to mention that it's powered by a USB port means you can take it anywhere and always be ready to charge.

The optional QC3.0 adapter they include isn't a knock off, it's well built and works perfectly.
