An automobile power inverter is an electrical transformer that takes the 12-volt direct current (DC) and changes it to 120-volt alternating current (AC). That allows you to run small electrical devices that you normally plug into a wall receptacle. Your auto electrical system is a 12-volt DC...

Thanks. I have seen these but think that a small inverter, like I linked, would be a handier device as it can be used on other devices as well, not just an Apple air (any other trip may have a different laptop etc) Would the inverter work? Apple calls their charger 45W magsafe2, so I assume it’s...

A car battery rating of 40 amphour (Ah) is fairly typical. This means that it could supply 4 amps (i.e.. run the inverter at around 50 watt for 10 hours). Running at 40 amps, the battery will last for significantly less than 1 hour

You need an inverter that suites yoru needs and a large 12-13.5v battery. There are a few emergency jump starter units that have this built into them but they are really expensive(150+ Dollars) Most modern nverters have voltage protection so they will shut off and alarm when the battery gets...
