I'm surprised with how good this charger is, for the price. It's sturdier than others I've bought and the two 18650 slots charge independently with two indicator lights that work independently. Really not a bad charger at all. Mine doesn't get very warm when it's at work, either, which has been a problem with cheap chargers. I'm ordering a second one for my travel electronics bag.

I have had this for a while now and it works great charging lithium batteries. It can be modded to also charge the CR123 lithium batteries by soldering a couple contacts. Use it daily to charge 14500 batteries for my flashlights and it has been perfect so far.

As stated above, I bought this as a backup to a trustfire charger which has been very reliable. This ultrafire is proving just as reliable. They are similar in many ways. The LED's start out red and turn green when the charge is complete. This one charges at a slightly lower rate(450 Ma. vs. 500 Ma.). The lower the charge rate, the better it is for the long term life of your batteries. This charger and the batteries get warm, not hot. I get into that more in my trustfire charger review. I've read some reviews where people have had problems. I think these are just sample defects, as mine are very reliabliable. I would buy this charger again if I had the need.

Really pleased with this product I read a few bad reviews but mine appears to work perfectly really fast charging and great price. Also smart enough to know when battery is fully charged. Tried to put a fully charged battey back in the charger and got the green light. Most cheap ones wold start the charging process over again.

Bough a flashlight for my hubby which requires special rechargable battery so had to purchase this charger as well. My hubby likes it a lot since the flashlight only requires one battery so he can recharge the battery and still have a spare one to use since the charger has two slots. Works great so far.

I bought this charger to charge Trustfire TR18650 3.7V flashlight batteries. I bought this item from Crazy Cart and looks exactly like another one I ordered from a more expensive store. It charges the batteries - what else can you ask for.
