Good design choice with

"Good design choice with the charger built in sadly a very poor performing battery. I am getting about 30% of the expected run time with these batteries. Buy many because you'll be swapping them often."

"I really like the USB charger port. I don't have to keep a special dedicated charging unit on hand and if electricity isn't available, I can use a solar powered power bank or an adapter in my car. It's a tiny battery but provides good power."

I love these batteries!

"I love these batteries! They are so great for my daily carry flash lights. I have had trouble finding them online lately but I found out Fenix carries them here and can buy them direct. The ability to charge it with a common usb cable is just genius. I have 4 of them on rotation and keep all my EDC flashlights charged up and topped off!"
