If you need a charger for 21700 cells, this is the one!
A great battery charger for my 21700 batteries. It is hard to find a charger that will charge 21700's. This was the only one I could find that would actually work with the slightly longer cells with a button on top. A great quality product. Works well. Was able to charge my cells to 100% without any problems.

Great Product
I use it to charge 18650 batteries and it is the best battery charger I have owned. High quality, fast charger. Having the ability to charge 4 batteries at once is amazing. I highly recommend.

This charger does everything! It charges fast it also let you know if a battery is bad. My other battery chargers do not..

Stay on top of charging metrics.
This charger is used form recharging CR123R, 18650, AAA, AA, and other batteries. The informational display is a good indication of battery status and charging status.

Don't know
It came with a USB-c charger but it's a standard USB charger. I didn't use it, I'm just sending it back. I never have issues with Nitecore, they're one of my favorite brands but the idea of using a USB charger when it came with a USB-c cable. Just doesn't sit right with me.
