Since this is the sequel, you get two USB ports instead of one for simultaneous gadget charging.

The Magic Box walks you through what Sanho claims is a five-minute process of modifying an existing charger to connect to HyperJuice, requiring some light. And it manages that, boosting my Retina MacBook’s battery life to around double, and providing quick access to plenty of juice for both iPhones and iPads. There’s the battery itself, with the Magic Box DIY kit and a car charger, or a fully modded setup, which also includes an 85W MagSafe Power Adapter and MagSafe to MagSafe 2 Adapter.

The HyperJuice 2 can provide that power, and lots of it, enough to double the life of a new Retina MacBook Pro, and extend considerably longer the life of other, less power-hungry Macs. But often, those devices have less power than we’d like them to, especially when we’re traveling or fighting for socket space at a coffee shop or conference. Do you like power? It’s very useful for using all those electronic devices we have. The BatterBox Slim can charge any laptop or USB device, including MagSafe 2 MacBooks (Air and Pro) and the 12-inch Retina MacBook that features just a USB-C port.
