Bought this to replace a cheap charger that came bundled with some 18650 batteries I bought a while ago. Love the ability to charge at different voltages. I usually leave it on the slowest speed but sometimes I max it out when I have a few batteries that need to be charged ASAP. Takes a low cell to full charge in about 2 hours at the 2.0v charge setting. Also seemed to rejuvenate a couple of my older LG batteries. USB connector is awesome since I can take my charger in my truck whenever I go somewhere. I run button top 18650s in my flashlights and it charges them just as well. If you can get this charger for under 20 just do it. You won t be disappointed..

purchased this charger mainly to charge my flashlight using 18650. The rapid charge idea got my attention. I play a lot of airsoft, especially in the dark. Normally i have to carry lots of battery for my sight and flashlight and need to charge them a night before. with the rapid charge, it cut my charging time a lot.

I purchased this charger for my rechargeable Li-ion 18650, 16340 and 14500 batteries and was not disappointed. You can control the charge rate with the push of a button. You can 34; charge at 0.5A or you can go to 1A or 2Amps if you are in a hurry and the battery is rated for it. This is a great feature that you can 34; a lower charging rate which can help to prolong your useful battery life. Customer service are the best I have found from anyone. I highly recommend this product and this seller!

Bought this for my new mod that requires two batteries. The initial charge for brand new batteries takes a good 4-5 hours, but after that it takes 2 hours to fully charge the battery. The built in safety for overcharging is a big plus. I can charge my batteries at night while I m in bed and have no worries about ruining the battery.

Used this charger for 2-3 days before returning it because I found my Nitecore charger will charge 20700 batteries even though it doesn t specify it. The charger isn t bad, but 20700s are an extremely tight fit and I m sure would damage the wrapping if I kept using it. Not a bad charger at all, seems like good quality, but just not the best for 20700s.

Quality charger, charges fast and helps save money buying non chargeable batteries. The charger is light and small, convenient to carry around or keep as a back up. The price point is right for this good quality, I expect it to last.

Amazon Customer

Seller is committed to customer service. They followed up with my purchase, and I only made mention of something in stride: they strove to correct it, immediately. Otherwise, product charges at three different voltages per your specs, and has an easy to read and bright battery meter for each of four slots!

Eric Fan

Have used about two weeks, charge very quick and long lasting. Saved a lot of money for me, my son love to play Rc cars, the battery is too expensive, the rechargeable one is a better alternative!

Amazon Customer

We have one big chunk of charger for the AAA and AA batteries each. Finally got a smart One you could charge different sizes on this! Great quality and past CE ACC regulations. Very impressed!

Charger charges batteries, up to four at a time! I use this for all my flashlight batteries. Compatible with many different size batteries.
