How do I properly use HyperJuice battery for MacBook?

First, do not keep the HyperJuice battery plugged into the wall all the time, as it might shorten the lifespan of the battery.  

Unplug the battery from the wall once it is fully charged. The power storage is up to 6 months without use.

Second, for longer usage time, either with Magsafe Airline adapter or HyperJuice Magic Box solution, it is recommended to have both MacBook and HyperJuice battery fully charged.
