18650 Battery Charger, Suitable for Lithium Battery 18650 20700 10440 14500 18500 16340 17500 Battery Charger, USB Single Slot li-ion Rechargeable Battery Charger (Battery not Included)

I thought I was buying battery, When this arrived I charged my battery and low and behold worked great charged in no time at all .I was reading the reviews and found out that I can charge all sizes of batteries. I like it more now. GReat little charger, a must have.

I needed a battery holder for various size batteries, AAA ,AA, 14500, 18650, etc for use in testing batteries. I couldn't find any one making one of these neat sliding contact battery holders for stand-alone battery use, so I bought this one to get a simple compact battery holder. I removed the charging circuitry and hooked it up with a new cable with a universal RCA connector. Works great, and it's really compact, and able to handle all my test batteries up to 18650 size Li-ion batteries. BTW...if you hit the bottom with a heat gun, the glued-on bottom comes off easily for access to the circuitry.It probably also works well as a battery charger...but I didn't try it out for that. But it has a great easy to use battery holder. I've now used the battery holder a lot on all sizes of batteries...highly recommended.

I have a couple of flashlights that take these kind of batteries. I bought the charger and it works perfectly.

Cheap and light weight construction. You will need a free USB charging port to use. But it does work and has LEDs to show when battery is charged.

Works very well

This was a perfect purchase. I use my flashlight all the time for Security.

Works well in charging rechargeable batteries.

Didn’t work seems to be a theme with these
