Charger

Good brand and quality product.

Quality charger so far

Simple and works well

Convenient for carrying around.

I keep a phone charger, small power cell, cables, and a couple extra 18650 batteries in my work bag. I've wanted to have a charger instead of having to plug in my lights (headlamp and one in my pocket) but couldn't find a small one until I saw this. I didn't need a dual battery charger for this and those were more than twice the size so would take up unnecessary space. This was perfect for my use.

Nice Charger but Micro-USB

This charger is easy to use and small enough to take anywhere. Drawbacks include the micro-USB connector and its relatively cheap feel. I wish it were USB-C. Other than those issues, it has worked on a variety of rechargeable batteries.

Good Charger

Unit is as described. Charges one battery at atime.

G**S

Great product

It appears to be a good battery charger.

Solid piece of gear

Great for portability, this little charger makes peace of mind a reality, especially on those long trips away from ready access to grid power. I bought this for camping, and specifically because it will work with my external battery pack, so I have now consolidated my charging requirements into a single form-factor for cable/battery/charger/phone. The only thing I would have done differently would be to add the capability to dim or disable the charging LED, since it is SO bright. It's a small, blue, 3-segment charge indicator, but you could nearly light up your whole tent with the LEDs. Little bit of gaffer's tape takes care of that. Very pleased with the purchase, and would buy again, if needed. Nitecore produces top-notch products that won't let you down.

Charger for 18650 Lithium-Ion Battery

The charger works. It takes at least 4 to 6 hours to charge one battery but once the battery is fully charged then the flashlight I use goes to full brightness which is about 1000 lumens. This charger works and it also prevents the battery from being over charged.
