Inverters turn battery current (DC) to household current (AC).  Most items that you plug in the wall at home can be powered by the inverter.  High draw devices can be a problem. (hair dryers, space heaters, etc.)  Inverters are very hard on the battery bank and are inefficient when using a big inverter to power a small AC load.  I bought it thinking I would power my induction plate.  I wanted to use it instead of a propane stove to keep the van temperatures low in the summer and as a backup if you run out of propane.  This is a modified sine wave inverter and the induction stove seems to require a pure sine wave inverter.  I have used it to power the tv/monitor and the laptop and maybe a dozen times to run my shop vac.  It ran the jigsaw too.  You might not use it enough and decide to sell it.

Inverters pull power even when they are turned on but not doing anything.  That’s why I put that battery switch down in that compartment that you reach your arm into after removing that cup holder.  Shine a light in there and make sure it is off until you need it.

Pure sine wave inverters are a good deal more money.  My camper has a 1200 watt pure sine wave.  I have used it all this last week to power my laptop and then I have a small inverter plugged into a cigarette lighter socket that powers my cellular router.
