All You Require Is A USB Socket!!! August 6, 2022 Reviewer: Michel J. Gaudet from Adams, MA United States   I am EXTREMLY pleased with my purchase of the two units I bought.  I LOVE that I do not need to 'find' an un-used electrical socket to plug into.  I have USB sockets almost everywhere throughout the home, so that is a HUGE plus for these two bettery chargers. The best thing, regarding the device, is how EASY it now is for me to see batteries needing to be replaced.  I have other 'chargers' that will allow this, but only by knowing how to GET to the resistance feature.  The "NITECORE" device AUTOMATICALLY SHOWS YOU THE VALUES!!!  I don't have to remember special key presses and such.  YAY!!! I bought TWO of the devices, but if this-here "Old-fart", what's in his 70s, starts getting geared back up again towards needing to have heaps of charged batteries 'at the ready', so-to-speak, I just may end-up getting a few more!!! OH!  I just remembered.  Pulling the connectors to fit in batteries?  SILKY SMOOTH with NO binding.  THANKS, "NITECORE"! Was this review helpful to you?

Great compact versatile charger July 19, 2022 Reviewer: Johnny Utah from San Jose, CA United States   I was so impressed with the UMS2 I bought the big brother to keep at home. The UMS2 is perfect for keeping for use on the go due to its natural smaller size. The UMS4 replaced my D4 and is my go-to for charging batteries at home. Was this review helpful to you?

Great AI type USB battery charger. July 6, 2022 Reviewer: ChrC/4istopher Cable-Cheval from HSoDak USAartford, SD United States   I looked high an low for one of these USB powered AA-AAA type battery chargers to use with my on-the-go solar panel. We like to have spare charging batteries for our RC vehicles and also our metal detecting gear. Little did I know this unit has a sort of AI chip in it to detect a wide range of other batteries/cells I use. I really lucked out. Was this review helpful to you?
