Automotive electrical systems are dirty. Voltage spikes from the alternator, load dumps, and accessory cycling can push well past 14V — enough to damage sensitive electronics like the RaceBox Micro over time.
This is the converter we run on every hardwired install. It sits between your 12V tap and the RaceBox USB cable, delivering a clean, regulated 5V regardless of what the car’s electrical system is doing.
