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.
