HUDWAY Cast has no battery and therefore should be connected to a 12V power outlet to operate. Enclosed in the box is a cigarette lighter to USB 3.1 Micro-B cable 2.4 m (7 ft 10 in) long. There are two USB ports in the socket adaptor piece, which allows for simultaneous charging of two smartphones — the electronic specs are the following: Input: DC12V Output: DC5V — 4.8A.
Alternatively, HUDWAY Cast can be charged from a car OBD-II port (where it's not prohibited by the car manufacturer). When the campaign is finished, we'll be selling OBD-II to USB 3.1 Micro-B cables at our website, hudwaycast.com. The length is the same —2.4 m (7 ft 10 in). This type of connection also allows for getting the car data (where it's allowed by the car manufacturer) — speed and RPM — and bringing it to the heads-up display.
