Tech Review: Batteries That Go With You
With 300 days of sunshine in Colorado (I know that may not be totally true but we he have tons of sun!) why not harness that power to charge your phone? The Waterproof Solar Power Bank from EverythingTechGear.com is a solar panel and battery in one. You'll need to charge it up from a standard USB charger initially but after that you can keep it juiced using the sun. It has 2 USB ports so you can charge 2 smartphones at the same time. It's rated at 12,000 mAh which means you should be able to get a handful of charges to your phone before you need to charge it back up.
