Love these batteries and the idea is long over due. I use them as a back up to my duel fuel Streamlight flashlight, so I can always recharge in the field and no charging cradle needed. Also works great in my weapon mounted light that takes CR123s as well.

    area suffers regular power loss, usually due to weather. rechargeable batteries are the way to go but without power, you’re in the dark. unless you have a solar battery bank & usb rechargeables. these work great with or without a power grid

    Using it right now. Very convenient to have the USB input right on the battery.

    Using it in one of my old Fenix pocket flashlights, it works great and I am not hunting for CR123 batteries when one dies.
