I want to inflate an AeroBed mattress with built-in pump when camping. Is there anyway to get 110V 60Hz power from a car lighter?
Yes, there are inverters that plug into the cigarette lighter socket that have outputs of 120 volts. To estimate the size of the inverter you will need, find the wattage of the pump. If there is no wattage stated on the label, multiply the amperage stated by 120 volts for an answer in watts. Amps x Volts = Watts. You should obtain an inverter with a wattage slightly higher that you need, for the air pump.
