Smart USB Charger, Compatible for USB Adapter with LED Indicator, Intelligent Overcharge Protection

Broke after second use on 1st one and a week later on the second one. Cheap plastic!!

It's not universal. It did not fit my friend's curaleaf battery. I gave it 2 stars due to the battery isn't too common, but common enough to be recognized by vendors.

These really suck. They always break or stop working after a few uses but I don't know of an alternative so I keep wasting my money.

The threads are to spec but the plastic casing makes this incompatible with even a very slender battery. Absolutely worthless design.

Worked great to charge my KandyPen Special-K after I had lost my charger. Now I have two I can keep in different places for the same cost as ordering one directly from KandyPen.

Works great with my Backwoods and Sweet Stuff vape pen batteries and even fits perfectly in the Sweet Stuff brand carrying case.

great. so great
