Description: This is device that plugs into the 12-24V outlet in cars. It has a barrel plug connector that measures 5.5mm x 2.1mm, center positive, with an output of 7.5VDC and 1Amp (supposedly).
We tested one with a 12V supply and got about 7.6VDC open voltage and about 300mA short circuit. These could be good for powering an Arduino or other microcontroller from your car. As long as you don't need more than ~250mA of current, this should work just fine.
Cable length is 3'3".
