Works great for rechargeable batteries!

Battery just a little longer than ultrafire batteries but will still fit in ultrafire flash light.

I like the usb charger, the batteries work, but I found they do not last longer than the 1500mAH batteries they were to replace. So I think the 9900mAH capacity is either incorrectly calculated or an exaggeration, you decide. Gave 4 stars because expected them to last longer with bigger gas tank, but they do not.

Love these rechargeable batteries with charger.

Timing couldn't be any better. Needed to charge my LED flashlight battery, due to a faulty charge circuit in the flashlight. Now I have spare batteries for my flashlight. Accept different sized rechargeable batteries to.

I’ve had this for about a couple of months and already have major issues. It will say all the batteries are charged but when I put them in my vape they’re at 2%. Or it says it’s charged 100% and then the batteries are dead within an hour. Doesn’t fit the bigger batteries. I’ll leave the batteries to charge for 4 days and they still aren’t charged. Seriously the most awful piece of equipment I’ve ever wasted my money on. 0 stars is my real review!

Delivered in a timely manner. Only used one battery so far; was fully charged out of box... powerful light.

Item is meh. It works but is very cheap. Batteries don’t hold that much of a charge and I’m fairly certain the charger doesn’t have overcharging protection. It’s just on or off. It worked for what I bought them for, but I’d probably try to find a different brand next time if the price is right.
