Convert AC machine to DC

Help, I have a halloween project that I need advice on. I am new to electronics.

I have a 400w 120vac fog machine that normally plugs into a wall socket. This model


I want to be able to carry it around with me on halloween. What type of DC power do I need? I assume i need some type of inverter?

If I get a 12v dc battery, are there options? I can't really carry a car battery around all night, as they are super heavy. What are my other options? Could I use one of my rechargeable drill batteries? would they last?

Do I need a 400w power inverter? or more to be safe?

I don't really understand how it all works, so I am asking all of you for help.

Basically size, power and cost are my three limiters... any advice is appreciated...

cheers,
-e-train

Have you considered dry ice and water? There are also certain chemical mixtures that can make fog. Either case no electric needed.

Yes, the size would be too big to carry around because that amount of power from an inverter would take a large car size battery.
The cost would only be a problem if you do not have a lot of money................about two hundred bucks for a deep cycle battery and an inverter provided you have a battery charger.

You need a small portable fog machine.

To make the one you have portable, you need a 500W plus inverter, and a couple car or better batteries to supply the current needed..

Bee smoker. That would be another non electric solution.

Agreed, I'd look into a non-electric solution. Typical electric fog machines have a fan and heater which suck up quite a bit of power. Supplying that much power via batteries is tough and heavy.

I'd certainly recommend dry ice - you can have a lot of fun with it. If you've never handled it before, read up on safety. Not a lot too it, but it can cause some pretty good burns if you're not careful (speaking from first hand experience).

It's also pretty cheap!
