IMPORTANT: Requires MagSafe Airline Adapter (sold separately by Apple).
Pocket Power for Mac and iPhone
HyperJuice is the ONLY external battery and car charger solution that works with ALL MacBook, MacBook Air and MacBook Pro (supports dual voltage). The HyperJuice battery also powers the iPad, iPhone, iPhone 3G, iPhone 3GS and all other USB devices (i.e. Chill Pill). Now you can untether and job escape (saradasu) at an entirely new level. It's also the perfect off-the-grid power source if you bike-to-work.
Power your MacBook and any USB device simultaneously.
HyperJuice External Battery comes with a USB 5V/1A Power Port so you can power any USB device (e.g. iPad) individually or simultaneously with the MacBook. MacBook regards the HyperJuice connection as a connection to the original power adapter. Not only does HyperJuice provide power for the MacBook, it charges the internal battery as well. You can check the HyperJuice battery level anytime with the lighted indicator.
Extend the life span of the MacBook internal battery.
Using HyperJuice external power will help reduce the strain on the MacBook internal battery without sacrificing mobility from the power grid. Constant usage will at least double the internal battery life span, which is important considering newer MacBooks all have built-in non-removable batteries.
Supports MacBook Pro Dual Voltage
Did you know that the MacBook Pro operates under 2 different voltages? It uses 16.5V for normal operations and switches to 18.5V for intensive tasks. HyperJuice is the only external battery & car charger that can automatically adjust between 16.5V & 18.5V, just like the original power adapter. Other solutions just stick to one voltage, never able to power the MacBook Pro accurately or properly.
Professional Grade Battery
HyperJuice External Battery uses the same high end lithium ion cells that is supplied to the U.S. military. It is rechargeable up to 1000 times and comes with a ONE year warranty. Compare that to industry standards of only 300 recharges and 3 months warranty. The beautiful aluminum housing, laser engraved logo and all-white accessories are color matched to complement the MacBook.
Power is beauty when it comes to your Mac.
