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.

Great charger

Great running charger. Stays cool, simple to use. If I had any complaints I wished the lights turned off when the batteries were completed charging and the batteries were a little easier to get out of the charger. I keep my nails trimmed as I am an auto mechanic and it’s difficult to put the batteries up and out. It would be great if there was a button or something that pushed them out of the slot to make it easier to grab.

The charger was great, awesome... Something I was super excited over purchasing... I purchased for work, to charge my 18650 Li-ion batteries for my light I wear on my hard hat, as I work night shift.. 12-18 hour shifts each, product worked amazingly for the first week.. until the LCD screen just suddenly stopped working.. I am currently in contact with the company discussing the warranty options as I type... But overall.. I think it's definitely worth 30 bucks!
