Power Your Portable Devices in the Car

Almost any small consumer device can be run on car power, and if you can’t find the right adapter you can usually make one.

There are many portable devices that can bring music to your car, but unless your device is very popular there may not be a specific car adapter for it. Nonetheless, by figuring out a few vital statistics about your device, you can adapt it to work in the car.

The main data you need to get a device working is:

Voltage

You need to know the voltage of the device, and whether it runs on AC or DC. The ideal candidates for running on car voltage are DC and between 1.5V and 12V.

Amperage

You need to know how much current your device wants. More amps, in general, require thicker wires and a bigger adapter. The easiest devices to power are under 1 or 2 amps.
