18650 Battery Charger 2 Slot, BESTON 18650 16340 16650 17650 17670 18350 18490 18500 20700 21700 26650 3.7V Li-ion Rechargeable Battery USB Charger.

This is better than expected as i can charge all sizes of my batteries. Not just the odd shaped that is for my door bell camera

So far so good. Perfect to keep the spare vape batteries fully charged

Great little charger for my 18650 vape batteries. Easy to use with spring loaded bays. LED lights show when charging and fully charged.

I like this brand

Great

This charger is cheap but great! It can’t display each battery's charge level while they are charging, however, which can’t change the speed of charging, either. It can charge different size batteries which is also nice. Favorite thing is that it takes a USB cable instead of a wall plug in which is super helpful for on the road needs. Light weight which is also nice for travel, been using it daily for almost a month with no troubles. Great price too, very happy! I've bought several battery chargers over the years, so far this one is my favorite!

Very simple yet effective charger. It charges all my rechargeable 18650 batteries. Universal because it is USB powered, I just plug it into one of my high capacity battery banks, or my pc, or my usb wall outlet and it charges my batteries. A very simple, yet very efficient charger.

So far, this two battery charger is great! The charger is quit simple. Red means charging and green is full. It is quite inconvenient when I want to check how long the batteries will be fully recharged. Even though they are different sizes, I can charge two 18650 and two 20700 batteries at once. The only complaint I have is that it does not come with a wall adapter for the USB cable, but if you're like me, you have plenty of those lying around the house.
