Reddit mentions of POTEK 500W Power Inverter DC 12 V to 110V AC Car Converter with Digital Display Dual AC Outlets and Dual USB Charging Ports for Tablets, Laptop and Smartphones

I use my car as a generator when camping and it is awesome. I usually use it to run a few lights, charge electronic devices, and speakers. It burns very little fuel and probably burns at a rate of 1/10 a gallon per hour.

I've been using this inverter and I really like it because it displays the output. It helps me ensure I'm not overloading my car. With all my devices, I'm using only a max of 30 watts. Although it's rated for 500w, I heard you arn't suppose to run it that high without it directly connecting to the 12v Battery.

I've successfully powered a PS4 and computer monitor in my car, works very well. The tech specs for the PS4 say 165 watt maximum. Any monitor or TV you use should have it's specifications listed as well. Here's an example of a pretty inexpensive one, it says 24 watts. Then just buy an inverter that exceeds the total of the PS4/Monitor/anything else you'll be using at the same time. Here's a reasonably inexpensive inverter that says it'll provide up to 150W if you're powering it using the cigarette lighter, otherwise you have to hardwire it to your cars battery (that's what I had done, the hardwire route) and it'll provide up to 500W which should be plenty

You can get a decent enough ac inverter for your car for about the same price and not risk overcharging and damaging your board by not using the factory charger.

As long as it's wired straight to the battery and no plugged into the cigarette lighter something like this would work just fine.

Some people have meantoned that you need a pure sign wave inverter. This is absolutely false when you are using a charging brick. The ac to DC transformer in the brick will output the correct power no matter what.

Is that 15 watts of power consumption or 15 watts of output. A 15 watt tube amp will consume much more power than it puts out.

That unit will put out enough power to run an amp, but probably not for very long. It's designed to be able to dump a ton of power for several seconds to start a car but doesn't have enough battery storage to add up to any kind of sustained use.

Maybe an extension cord and find a kind soul that will let you plug in.

Maybe a 12v car battery (borrow one from some car or boat or something, big 12v batteries are everywhere and store tons of power) then get a 12v to 120 volt converter for relatively cheap.

This would work https://www.amazon.com/POTEK-Inverter-Converter-Charging-Smartphones/dp/B01B3ZQG4O/ref=sr_1_4?s=electronics&ie=UTF8&qid=1492750241&sr=1-4&keywords=inverter

and doesn't start your car or pump up your tires or other things you don't need.

Your play time would be limited only by how much power you consume and how much battery you've carted with you. With a small solid state amp and small mixer, expect to go for hours off of a car battery.

Edit:Another possible strategy I've sometimes used is to keep a car idling close by, put an inverter on it, then run an extension cable from the car over to the music. I've run a small band off of that.

Has a much bigger battery, has an AC inverter. Only issue is the inverter is rated up to 120w. This mean you can run a laptop and other small devices but don't expect to get to run things throughout the weekend. Much better than what op linked. However w/ the panel it's almost 4x the price.

It sucks that the solar panels cost extra but if you were to buy now, the 25w panels are on sale. I would get two and hopefully get up to 50w (under optimal conditions).

It would be nice for car camping or a camper. If it's a permanent or even semi permanent installation, It would be better to purchase a larger panel, solar controller/charger, deep cycle large capacity battery and an inverter.

Ends up being a $270-$300 investment. That's not bad. If you were to buy the monoprice system w/ larger solar panel, it would be close to $300 and it wouldn't anywhere as efficient as if you were to make your own system. Only thing are sacrificing is portability and weight. A 8Ah battery will be much smaller and lighter than a 100Ah+ SLAB but won't last anywhere as long. If you have a rainy/cloudy week, good luck.

I have a little 400W inverter for my car. It hooks straight to the battery. I run an extension cord into the house and plug the tank's power strip into it when our power is out for extended periods. I can safely idle the car outside as long as i need to. (Acts like a generator)

Here is one that is similar:

If you really want to be sure you have enough power to charge your batteries and phones, consider picking up a spare car battery and an inverter that'll hook directly up to it. Something like this:
