Charged but only one side at a time

Advertised to charge two batteries at a time but only charged one battery at a time. Maybe the charger block had insufficient power. I just expected it to work.

Dual Slot charger...another great product

I ordered this charger so that I could charge any of my rechargeable batteries....20700, 18650, RCR123 and it does a great job for less money than other chargers with similar features. I only wish it used a USB-C cable so that it would compatible with newer phones' cables.

Just what I was looking for...

I picked these up as gifts to go with a couple of flashlights I'm giving as gifts. I wanted a simple, no frills charger that newbies could use to charge 18650's or 21700's and these should do nicely.

Nice charger!

I am very pleased with this 2-station charger. I can plug it into any mini USB power source and I am charging. Bright blue LED's let me know the status of the battery and the charge. Works great.

Perfect charger

Works great. Not as advanced as some of their chargers, but works perfect for me. Price is right, too. May recommend the wall plug in addition, as the charger needs to be plugged into a usb socket. Unless you have one laying around.

3rd charger

This is the 3rd charger I have bought in the last 2 years. The connection where the cord goes gets loose and will not work. I bought the portable on accident but it is doing what I need. I'm sure it wont later long either. I couldn't find another brand is why this is the 3rd.

Good service

The ordering was easy and the service was great. My only issue is the battery charger is finicky. Meaning you have to put the batteries in a certain position for them to charge.
