How do I get the HyperJuice battery and DC Airline adapter to work with the MacBook?

In order to get the HyperJuice battery and DC Airline adapter to work with the MacBook, a magsafe airline power adapter is required.

Users can get the magsafe adapter from the Apple store (http://store.apple.com/us/product/MB441Z/A)  or on Amazon.com.

With a magsafe airline power adapter connected to DC airline adapter and plugged into DC Out on battery, the HyperJuice battery will power up the MacBook, but it does not recharge it.

This is because the magsafe airline power adapter is not designed for charging.
