    Wow

    Tony

    Very light, ran my Vexilar for 2 full days so far and haven’t recharged. Trying to see what I can get, but very impressed. The USB’s are great as my phone battery doesnt last in the cold so I have used it in the shack to recharge that a few times as well. Awesome product!

  4. Lightness and Efficiency

    Joe Cartwright (verified purchase)

    I received the order right away, took hardly any time to charge battery. I used the battery in an underwater camera for the next two days and did not lose any power. Camera ran for two (2) 8 hour days. Another big surprise was how light this battery is.
