When you’re out of juice, you’re out of touch. But that won’t happen if you’ve got a HyperJuice plug in your bag. It’s much more than just a phone or tablet charger. The HyperJuice P10 contains a BIG 10,400 mAh battery but weighs only 12.7 ounces (16 ounces for the bigger 15,600 mAh “P15” model.) Even without access to an outlet, the P10 will fully recharge your iPhone 7 times or provide up to 9 hours of extra uptime for your iPad. Also works with Android phones/tablets or any USB-powered device. Available in several stylish colors at Hypershop. $129.95 for the P10, $159.95 for the P15.
