Great charger in an awesome price!

Overall, I’m very satisfied with this charger. It does what I needed it to do. I love the the digital display after coming from my Olight Omni-Dok. I’m looking to also buy the new Nitecore UMS4, so I can charge more batteries at once. I just wish mine came with a manual, I don’t know why mine didn’t come with one. I’ll just have to go download it online.

  • What device/application do you use this with? Charges just about any rechargeable battery


Upgraded my charger with this one and it is spectacular. The screen display is great and seems accurate. My only gripe is I wish it would default to low power charging instead of defaulting to fast charging. I have plenty of batteries charged at one time so I don't need batteries charged quickly. So when I put 4 batteries in the tray I have manually select each one and set it to "low" for slow charging. It's better on the battery too. Its not that big a deal, but its the only con I could come up with.

I love it and use it daily. This is my second one, bought just as a backup. I have been using my first one for about 3 years now with zero problems.
