John H.So far, so good. Far faster charging cycle than the generic, stand alone charger that I had been using. Charles S.One of the better chargers for a multitude of batteries including LifePo. Charles D.My last Nitecore lasted 10 years. I charge a lot of batteries between my flashlights and vaping.This one is a lot fancier. Jason D.Fast charging Mark G.Really good product, great price.StrawberrydrinkGood charger and 18650batterystore good as well.I really like the charger ,it charge fast , for my 21700 1 battery(4000) took around 1 hour and 30 or 45 minute ,which is good ,reccomind it for good quality ,(Update) i do like the charger so far ,but there is one thing will make me give nitecore 3 star instead of 5 and i think its common issue ,that nitecore states on there advertisment that the screen goes dim after 10 minute if you not touching the device , but that’s not true ,the screen never go dim at all , (all customers be aware this option its not effective)wish 18650battery store work on this with the manfacture because thats wrong statment to inform customers . Thank you ,5 star for 18650battery storeDexter LuaExcellentExcellentUnknownWorks okI was in a rush and bought 2 bay when I should have bought a 4 as my nitecore sc2 which I had for 2 years began smoking and burned out love how you can adjust the current charge rate my only issue is the battery resistance reader is all over the place 1 min says new batteries are good the nextsays there bad I used 8 batteries all with same resultUnknownnitecore ums 2This is my second nitecore charger. Its versatile with lots of features including charging the newer 21700. My old nitecore i4 wouldn’t do itKevin RandolphQuality charger w/ Internal Resistance MeasurementMost chargers nowadays have have adequate capabilities for Li-Ion batteries. This offering from Nitecore has an internal resistance measurement. This is useful for matching batteries or seeing which will not sag under load.James GantGreat charger for the price.At first I received The wrong charger. I contacted them and they sent me out the correct one and they told me to keep the one I originally received. Thanks!UnknownAnother good dealConsidering the number of different batteries it charges, I like it.Evgeny ZakharovSolid chargerInformative display, no complaintsUnknownExcellentExcellentH. GaerteFast chargerThis charger worked quickly to charge up my new batteries. I had a hard time finding a wall charger that was capable of delivering the amperage that this charger can consume, but that is not Nitecore’s fault.John KranceLove it!Nitecore never lets me down.Duane VickGood chargerWas able to revive a battery that would only charge to 2.9v.UnknownA+Helped identify which batteries were cheap Chinese crap.
