Nitecore D2 lithium ion battery charger - great features at a great price

The Nitecore D2 is a the perfect step up from the I2, providing the critical information you need to maintain your batteries. Have a discharged battery, but not sure if it's time to replace it or whether it can be safely recharged? The D2's sophisticated display, showing critical information like voltage, can tell you what you need to know. This charger also includes many safety features that make it a good choice for a small home charger.


All versions come with the AC wall cord, but the version with car adapter also includes a car adapter that can be used with a 12V cigarette lighter so you have charging options.  Select which version you would like from the drop down box.

Couldn’t get the Samsung 21700 batteries to fit

I’ll have to return the charger. It’s specs says it fits 21700 batteries. I was going to have to force the Samsung 21700’s into it but the instructions say not to. Maybe other 21700 batteries fit, the Samsung batteries don’t.

Great product.

This is a really great product. I’m a noob when at flashlights and batteries and this charger helped a lot. I don’t have to worry about damaging anything because the charger detects and does everything on its own. It’s fool proof. Also nice that it has a discharge feature for when you are going to store your batteries.

  • What device/application do you use this with? To charge batteries
