Using 12V lighter sockets to power appliances

Using 12V lighter sockets to power appliances

My model X has two cigarette lighters. One in the dash and one in the trunk.
Do they both run through the same 15 amp fuse, or is each one on a separate fuse?
Wondering how much I can run

Would use an inverter off each one

Is it ok to use an inverter on a Tesla?
I have a model3 and read somewhere not to use one.
I've got one from my old car but was afraid to try it.

I think it is quite safe if you use the inverter off the cigarette lighter sockets, But 15 amps is only enough to run my refrigerator and nothing else. If the other one also has its own fuse it will run 15 amps I can use it for other appliances. Hooking an inverter directly to the 12 volt battery would give more power but might void the warranty.

I have used the cigarette lighter socket to run a medium sized refer chest. I believe it takes slightly under 10 amps at 115v. However, it can really drain the available range away overnight and leave you with little range left...from experience. Very few appliances actually draw 15 amps, but more typically 12 amps or less at 110-120v.

Ok, 15 amps will blow the fuse. You're really should be thinking in the 12 amps area, or 12 amps x 12 volts = 144 watts.

There will be some losses if you use an inverter, but many are 90% efficient. In the conversion to 120 VAC, you should be able to get around 130W. This means 130W/120 VAC = 1.08 amps. Not sure any refrigerator can run on so little power.

I can see it now future posts from idiots:

So if you plug an inverter into your cigarette lighter and then connect your mobile charger to the inverter and try to charge the car would it create power so that the car would run forever.

That's better than installing solar panels all over the car or installing generators on the wheels so they charge the car as they spin.

However during a recent storm my brother lost power and took a car battery that was on a trickle charger into the house, hooked up an inverter to it and then wired it to a blower that was built into his fireplace to get warm air circulating in the house.

12v sockets: charging your laptop could blow the fuse/circuit breaker or fry something not eggs

mj4697237 | 05/05/2020

@Ross1 is it true? Can a 12v socket damage our laptop? I don't think so.

No, the laptop can damage the socket, simply put.

From my tests:

1 freezer: WON'T WORK with my 120v adapter
1 4k screen (2 amps 120v AC) + 1 switch + 1 router + mac laptop power: WORKS !

Yippee, thanks to my model 3, I can work remotely despite the fact that my electricity company shut the power down for the day.

looks like china is back folks! Not sure why though, they have a factory now
