Review on 2-Pack SNSYIY 3.7V 3600MAh USB Rechargeable Button Top Batteries For Klarus Flashlight (XT11X, XT11GT, XT30R.) by George Johnson

Revainrating 4 out of 5

Despite the label, these are NOT 18650s

I was ordering these for an oxygen machine that had an 8 cell 18650 battery pack. These came up in a search for 18650s and they had the highest power rating, so I ordered thinking they would make the oxygen machine run a little longer on a charge. They even say 18650 on the side of each cell. But they are longer and larger round than an 18650. They have a micro USB port on one end to charge as well, which was a nice feature, even if it wasn't needed. I did find a use for these, and they work great. but I couldn't use them in place of an 18650.

Pros
  • The batteries are easy to install and remove from the flashlight
Cons
  • The charger may be difficult to store when not in use, so it takes up more space than necessary
