This works as it says

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 bought these as a replacement for my Fenix 3500mAh. These are supposed to be 9900mAh which I didn't really expect. I installed it in my caving light and turned the light on to test it. It did great for 7 hours and then dimmed to unacceptable levels. My original Fenix if good for 10+ hours. I am happy with the purchase and would have given them 5 stars of they had held up longer. I would recommend them and would purchase them again.

Long lasting and fast charging

Exactly what I ordered

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.
