Miles ★★★★★

The protection circuit on the anode gives me real peace of mind when I’m cycling these through my headlamp on long night hikes, and the 3400 mAh capacity easily lasts me all weekend. Just wish they came in a two-pack for the price, but the durability seems solid so far.

Samuel ★★★★★

Using these in my flashlight now and the protection circuit gives me real peace of mind, especially when I forget to check the charge level. They hold their capacity well through repeated cycles, so far no issues after a few months of regular use.

Eli L. ★★★★★

Bought two of these for my headlamp and the protection circuit gives me real peace of mind since I sometimes forget to unplug chargers overnight. They hold a solid charge and haven't gotten warm during use, which is exactly what I needed for long winter hikes.
