Nice Charger!
"This is a nice charger. Has all the key stats for the batteries as they charge. I’ve used it with NiCd C and D cells and they charged fine. I’d recommend this charger if you only want to charge a couple batteries at a time."

Doesn't work with all batteries
"I bought this to replace my older charger that wouldn't handle the newer 21700 batteries. Now I can charge my 18650's and 21700 batteries, almost. I have Olight flashlights and their 21700 has a raised plastic rim around the positive button. The mating terminal on the charger has a raised dimple that is not quite tall enough for a consistent contact. If I adjust it for a few minutes I can get it to make contact but it's a pain. As this charger is marketed to accept all different makes of batteries I feel it is on them to make sure it does. Otherwise, I like this charger."
Awesome Charger from Nitecore!
"I needed a charger for 21700 Batteries and this one Does the Job Perfectly! Nice Display and compatible with Many Batteries!"
Quality Charger
"This is the first multi capable battery charger I have ever used. It is very simple to use and the display provides useful data. If you need a charger capable of charging a variety of batteries without the need to change any settings, this is your charger."

"Used for 21700 batteries. Worked as expected."
