I own and use one of these as a travel 18650 charger and have never had issues. I've also purchased several to include with flashlights I've sold to others and they have never had any problems. There were a few users here a while back who had issues with these burning out on use, but that seems to have been a bad batch and I haven't heard any complaints since.
Hard to be that, and BUYINCOINS is flakely, doesn’t send tracking and can take months.
I also like this one from Lightmalls, unlike most cheap charges, it has a built in curcuit that gives you the condition of the battery, without even being plugged in:
is so cheap is because it is a 2 piece clip on. I see the bottom part, the part with the plug and the charging circuit, everywhere. Depending on the battery, camera, 18650, or other Li-ion cell, there is an adapter portion that is clipped on the base that makes it compatible to that particular battery.
The charger on the left is the battery charger for the Panasonic camera that took this picture. Other cameras would have a different clip on to fit their battery. The charger on the right is the same charger with an “18650” clip on.
Here is a pic of the bottom, the 18650 charger even has a sticker that says it is a camera battery charger!
Millions and millions of these are produced to charge all sorts of batteries, therefore economy of scale allows the cheap price.
I have also been using one of them for a little over a month. Seems to work fine.
One thing I have noticed is that the light turns green a few hours before it charges to 100%. I think that’s normal for many chargers; I’m not sure. But I’m happy with the charger.
Yeah, I bought a couple of these, the odd thing about these are that the charge indicator light is on the wall adapter. The light on the battery holder just stays red all the time. When the light on the wall adapter turns green, then the battery is charged, weird…includes 12v car adapter…
