Incredibly light

About 8 years, I spent a month researching to find the power bank with the best weight to mAh (capacity) ratio. I found a 10k mAh batter that was super light. This 20k battery packs twice as much juice into a battery that is a fraction of an ounce heavier. WOW! Mostly I was just looking to upgrade my kit to USB C. I never expected to get twice the battery for almost no weight penalty. (Seriously, holding them in your hands, you can’t tell the weight difference). Very rugged feeling construction - and holds a charge with no measurable loss after a month. Highly recommend for any backpacker looking to upgrade their battery or buy their first battery.

Nice power bank

Used this on a backcountry trip. Kind of tricky at first to use. So pay attention to the instructions on the ports. Easily charges with a solar charger and provides ample charge to peripherals.
