EdisonBrightFenix are-D2 USB Powered Two Bay Smart Battery Charger for 21700/18650/16340 BBX5 Battery Carry case

This charger, amazingly, charges batteries. The battery level indicator is a nice touch.

Great little charger. I had bought a 4-bay charger for traveling but it's gigantic so I returned it and bought this, it's much better. It doesn't have a big power brick attached to it, just a tiny cable. Because of that, it can only do 1A max on each bay but that's fine for me. I like how you can select 0.5A or 1A for each bay independently. Be aware you only have 10 seconds to select that when you put the battery in, if you wait too long, just take the battery out and pop it back in, then make your selection. High quality product, doesn't have a gigantic screen with all sorts of info I didn't need in the first place, worth the price.

I have this model and a single. It allows you to charge any small battery to your specs while keeping an eye on voltage & charging amps. Much better than some multicharger and will give you a better charge I have tested it.

Like all Fenix products this charger holds up the reputation. Looks great,let's you know how much charge you have and it's built to last.

Works well but the first one I got had a poor connection where it plugs in, looking forward to the USB-c update

Charges good as described, but unclear directions on using to discharge batteries

Much better than two similar chargers I've used before - one of which stopped working and one that I returned because it was way too complicated and the instructions were inscrutable to me and I'm an engineer quite familiar with electrical stuff. The status display on this one is very informative.

Broke easily
