  • 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.

Nitecore d4 charger

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.

Great charger, great price and shipping

Love the charger. Can’t go wrong with Nitecore. First time ordering from this site, was very pleased. Ordered 6 LG HG2 batteries also and can say they work well!

Good Charger

Needed a new charger for the 21700 batteries. This one works well. Also have charged 18650 and AA recharge batteries. Digital readout is a nice upgrade from the lights from older charger. Highly recommend.
