How do I connect HyperJuice to MacBook

In order to connect the HyperJuice battery to your MacBook, you will need to use the Magic Box.

You can choose either the DIY version where you will need to modify your MacBook charger (aka Apple MagSafe Power Adapter). The modification process is really simple, takes only 5 mins and does not require any special tools.

Or if you do not wish to do the modification yourself, you can get the pre-modified version which comes with a MacBook Charger aka MagSafe Power Adapter that is already modified with the Magic Box.
