Some small portable starters can use a power supply that is greater than 12 volts.
Years ago I needed a jump start on my 1989 Jeep Comanche, the mechanic used a high voltage starter. The lighted controls on my radio never worked after that, some of the running lights were also burned out. Fortunately my dash lights were set for dimmed, those bulbs did not burn out.
