Question about jump box under the hood?

[STUGOTS]

Hey guys I have a quick question, I bought a 1500 watt power inverter to plug in 110 (household) things inside the car and the inverter says to hook it to the battery with these jumper cable looking things (im going to go buy the rings for a better connection) but I was wondering Can I hook it to the jumper box under the hood or do I have to run it directly to the battery?

Thanks guys.

Jumper points should be fine.

It depends on what you are planning on running with the inverter.

The change from 12V to 110V is going to cause a change of about 10x the amps drawn from the battery.

This is a ball park example but it's close enough for planning;

Say you have a small device that would draw 300 watts when you plug it in at your home to the 110v outlet.

What that means is that the thing draws about 3 amps at 110 volts.

When you plug that same thing into the inverter, it will still draw 3 amps at 110volts from the inverter,

but your inverter is going to have to draw 10x the 3 amps or 30amps of 12 volt from your battery in order to give you the 300 watts.

You say the unit can give you 1500 watts?

Well if it did, it would draw more than 100 amps from your battery.

That's about the amps you might draw while cranking the starter.

How long do you want to do that?

im going to be running like playstation and Xbox thats about it and NOT at the same time and they draw about 150 - 175 each.

Those things are going to draw about 10 to 12 amps from your battery.

That shouldn't be a problem. And you shouldn't need to connect directly to the battery with big wires.

Why did you get a 1500 watt inverter?

Don't forget the blender and magarita mix.
