In my part of the world most small electronic devices run at 5 volts this is to give them compatibility with universal serial bus on computers
Chargers or power leads for use in cars etc using the lighter socket are often a wee bit larger than they could be as they house the electronics to reduce the voltage from vehicle voltage to a stable 5 volts for use by the device
when travelling i use a wee harness that i plug into my battery charging pigtail that has a lighter socket on it and the charger unit for my mobile phone as battery voltage can vary from 12.8 volts to 14.5 volts the wee electronics pack does a good job of running the phone
a big spike of power would kill the electronics pack and not the phone new charger coast £1 if you shop around
Never wire an electronic device straight into the wiring harness of a vehicle unless it has been specifically designed to be fitted that way
