Rostra announced what it calls a new way for installers to power add-on 12 volt electronics.
Instead of searching for wires to power up devices such as heated seats or a backup camera, installers can now use Rostra’s SourcePWR, which is a 3-wire device that fits in the palm of a hand.
It connects directly to the car’s battery. It can detect when the car’s engine is on to send power to any connected accessories. SourcePWR automatically powers down these accessories when the engine turns off and enters a sleep mode so that no power is drawn from the battery
For about $39, it drastically reduces the amount of time installers need to spend searching for a stable 12v power supply, said Rostra’s Bill Simmons.
With the microcomputers in new cars it’s getting harder and harder to find a power source to make our products work. We get a new car, we have to probe all the wires to find power. You may have a wire with only 1 or 2 volts that’s also conducting data,” Simmons said.
