6pcs 1￵8￵6￵50 Rechargeable Batter￵y 5000mAh W￵i￵th 18650 Battery Charger,Universal Charger for Rechargeable 3.7V Li-ion Batteries 26650 14500 10440 Tokeyla (Button Top Type)

I use these in my battery pack for my NVDs. The are the right size, charge fast, and function the way I need them to. I burn them a lot of batteries and these have held up to the test and are a great value for the money

The strength of these batteries make the Atomic Beam flashlight brighter than ever before, however, the charge doesn’t last very long and the flashlight heats up with prolonged use. It works well for me and the limited use I need it for, but they need to be charged every other day.

I purchased this for extra batteries while on a live on dive boat for a week. I ended up using someone else's charger when I needed a fast recharge. It only puts our 0.3 amps or less. Would be nice if it had charge indicator. I have since replaced this charger.

I ordered this set of 18650 Li-ion batteries from Amazon after I could not find the size I needed anywhere locally. Fortunately, I was about to place my almost weekly Amazon order I had other items waiting in my Amazon cart!As always, I relied on the on the detailed reviews and ratings of my fellow customers when choosing a product about which I had limited familiarity - and Amazon does NOT let me down!The battery quality and chargers efficiency are key factors in my recommendation of this particular product offering.I find the batteries overall performance to be outstanding in my particular application (a fairly large, current intensive, Ultraviolet lamp (UVC)).These batteries are superior performers to many of the COTS offerings available (they exceeded the ratings during my initial tests and the use cases I’ve explored thus far) and a FAR CRY from what I was using previously - even though the inferior solution cost me more initially!From a charging perspective, the AC charger that accompanies the batteries is impressive, quickly recharging a variety of Li-ion battery types beyond 18650 I’m using and including the 3.7V Li-ion 26650, 14500, and 10440.Although not originally intended, I now use this charger for all my 3.7V needs.My next project will be combining a group of these batteries along with an external battery health / temperature / status monitoring circuit and charge controller to power some larger devices - my planned “homemade power cell” is initially targeted towards an electric scooter for my 13-year old nephew. In theory, it’ll work. 😜Bottom line, If you need an 18650 rechargeable solution for your power needs, this product is one stop shopping delivered!

I bought this to keep my 18650 batteries charged at all times for my head lamp at work. Works great. I just leave the batteries on the charger all the time, swap them out when I need too.

This thing worked pretty well for a while, but then all of a sudden the USB charge cord started to act weird touching the wire while it charged caused it to stop charging or flash weird orange lights, I assume there is a short in the wire somewhere.

Works great, I thought I had some dead batteries was my mistake. My flash light was broke

They do the job, seem to be well made, but battery life is average.

Son funcionales, sirven pero falta usarlas mas
