The Bolt Battery Charger combines the “world’s smallest portable iPhone USB wall charger” with a built-in 3000mAh rechargeable battery, so you’ll be able to charge your phone whether you’re near a power outlet or not. You won’t have to keep up with a special cable to recharge your backup battery, because the Bolt has prongs that fold down until you need them. It’s only 2.75″ x 1.33″ x 1.10″, but it packs enough reserve power to recharge a phone twice. It charges its own battery as it charges up your phone, so you’ll always have backup power even for your longest days. It’s $59.99 at REIGN|23.
