Our community has rated this post as helpful. If you agree, why not thank

Most cars won't see 500w through the lighter port though.

I looked at this to add to a small solar/battery backup system I'm putting together (still need an inverter) and I came across this:

"You cannot draw 500W through a cigarette lighter socket. The socket will overheat or blow its fuse well before you hit 500W. It's physically limited to ~150–180W regardless of what the inverter is rated for."

And it looks like it is maybe 18-20 AWG wire, so I don't think I could cut it and just use a different connector without worrying about a small wire trying to handle 500W

From the product description:
"You cannot get 500 watts from 12volt cigarette lighter plug, needs alligator clips for car battery. If you're going to be plugging this into car cigarette lighter,you should keep the wattage under 150,since that is what most car fuses are set for."

In for one, coupon worked for me.

As the others said, don't use the 12v accessory socket unless you like changing fuses. And at least do a test run on the wires and feel if they heat up under load. Replacing the wires is probably best. I'll be going with 10 AWG because I won't be maxing this out, but maybe research a bit. Should really be 6 or 8 AWG for the full load.

Needed to power a 600W ups, regrettably realized after the lighter port can only provide 12v x 15A = 180W. You'd need to connect to the battery directly. Also pay attention to the specs of the output if you need it at 120v. Most of these are actually 110V if the equipment needs 120V it will not be sufficient (like in my case 110v was out of its 120v tolerance range.)

Just tested the code AX7JYRGN myself and I was able to get the discounted price. Might need to remove from cart and refresh?
