This is a great little charger. I use it mostly to change my 18650's but have also used it to charge my NiMh AA and AAA's. It works well with both and you can charge both types at the same time. It has a small display that tells you the current change level and will tell you the capacity of the battery if charge from dead. I thought it had the ability to discharge and renew batteries but it doesn't. It's still a great charger and small enough to take with you on trips. You can select the charging amperage from .5-2a but I think it will automatically select the charging amperage based on charge level, type and quantity of the batteries too. The USB-C port makes it easy to plug in using just about any source as long as it can produce at least 2 amps. You can charge just about any size rechargeable battery up to a size C. Overall higher quality than expected. It's now my go-to portable 18650 charger.

It does what it's supposed to do, and the battery charge info in the LED display is a great feature.

I love that this charger fits a variety of battery sizes and offers both 0.5 amp and 1 amp charging modes. It’s versatile and convenient, especially for someone with multiple battery types.The only minor issue is that it’s a bit confusing when charging two batteries at once to understand exactly which battery is charged to what level, you can toggle the buttons to switch view, which is an extra step, but it does eventually show charging levels. Considering there aren’t many dual, versatile chargers on the market, this one is definitely worth it. It gets the job done!

I like that each bay charges independently (tired of the more common ones that have to be in pairs). And the display is nice, lots of info. I've ordered 2 or 3 (and may get another one) and the only issue so far is some of the pixels are out on one but I can still make out the info. And since the charger gets power from a USB plug I can even charge from a car battery with adapters I have (not included) - nice when the electrical grid is down.

So far this charger is working pretty good charging my 18650 and 22700 batteries for my vape.

Works great on a variety of battery sizes.

This product is advertised as being able to charge the 3.5v IMR16340 batteries, that the OLight Perun 2 mini requires.. I'm sending it back. Although the batteries fit it doesn't make a a good connection on either end of battery.
