Would anyone be able to let me know the risks/damage/wear and tear of a product like this on my vehicle?
Thanks in advance, John Smith
For the price of one of those things you can buy a pretty decent portable backup generator. Might not be able to run everything but you'll have power for essentials. Some can run on natural gas or propane as well as gasoline.
All lights and appliances are rated by the watts they use. Volts x amps = watts. Add up all the watts you think you'll be using in your house and see if this unit is capable of keeping up with any of it. I suspect you will be disappointed to find that the unit might be able to power a radio and one light bulb at a time. Of course, you could always turn up the idle on the vehicle and let the wear and tare be on the vehicle. For example, a 1000 watt microwave oven operated at 120 volts is going to need 8.3 amps to work. Most house circuits are 15 or 20 amp so there is plenty there. I"m just saying be careful where you put your money.
I looked at the website you provided. They say it puts out 1000watts. That is really not enough power to run everything "at the same time" as they would lead you to believe.
It's going to quickly wear out the alternator.
Your car wasn't designed for generating electricity. It won't be any near as efficient as a dedicated generator. Most of the fuel will be burned just turning a big car engine.
You can't even boil water or run a microwave with 1 kW.
