This question is about you would Go Big or Go Home after making choice.

In the last artcial, we’ve already knew that Xbox power supply can draw up to 600w during starting.

That means you may need a 600w inverter at least to use an Xbox in your car.

In practice, you probably get away with a smaller inverter (especially if you have a newer version of the console that isn’t quite so power-hungry.)

However, you should always want to need a bigger wattage inverter than the total numbers sahow you need.

You also have to figure out total power of all the electronic devices that need to work at the same time. So in the above example you’d better get 50-100 watts more for your TV or monitor, unless you have a video head unit or another 12V screen which can run itself.

Otherwise, if you go too big, you would need to have extra room for it. If you go too small, you’ll have another potentially expensive purchase for another power inverter.
