What advantages does your HyperJuice car charger have over other brands' Mac car chargers?

Our HyperJuice products including the car charger are guaranteed to work with ALL MacBook, MacBook Air and MacBook Pro models.

Unlike the other brands' products which can only operate at a single voltage (look at their specs), the HyperJuice battery and car charger can auto-detect which MacBook is being connected and adjust the charging voltage (14.5~18.5V) and power (45~85W) accordingly.

We are the only ones that can do this as we have a patent on this auto voltage/power adjustment technology.
