It's small and easy to use but very efficient and fast

Because I'm lazy and didn't bother to read exactly the description, its charger only, no battery! I had a battery already but thought having an extra would be a great bonus. For the price, I should have known better. But, it charged up my battery just fine and theres a nice little display showing you the charge progress.

First off, there IS an end on both sides, not open as shown in the picture. Not sure if I was sent the wrong one or not. Either way, needed this immediately, but the battery just barely wouldn't fit. My workaround was to take a lighter and a melt the plastic a little, and just press a screwdriver into it to allow the metal connector to slide back about another 1/8th an inch. Worked great after that. Charged the battery within about 2 hrs. (Just wish I had taken a picture before I did this to show exactly just how much it didn't fit). My 8800 battery did however fit, albeit just enough

Battery charger for specialized headlight batteries.

I placed my 18650 battery on this charger (a battery I've successfully charged with other chargers before), and plugged it in, but it gave no indication it was charging. I unplugged it and removed the battery, then inspected the charger. Turns out the movable contact wasn't making contact with the negative end of the battery, so I tried it again while the charger was still unplugged. When I put the battery back in, making sure it made contact with the negative end, smoke started coming out of the charger. I quickly pulled the battery out and one side of it was glowing bright red, and the charger was still letting out a thick, white smoke. I set the battery outside just in case. I would normally have avoided the review and just requested a refund for a defective unit, but this thing feels so incredibly cheap, and the experience was so dangerous, that I'm going to be doing both things. I lost a good battery because of this thing.

Works exactly as designed to do. Perfectly

Great value for money. Hopefully you’ve got more than one battery. Because this thing charges extremely slow. But it does the trick for the low price point. I’m extremely happy with it and it works just for what I need it for

Great price and quality!
