Hi Guys,

Does anyone have a source for mobile AC power packs?? just like was frightprops sells? I can't pay the frightprops price, I LOVE frightprops don't get me wrong and they were very good to us last year but I can't see the cost in their setup, do any of you guys out there know where I could find another similar mobile power unit or pieces to make one? I imagine a decent battery, but don't know how to create the proper outputs safely.

Harbor Freight has the exact same ones that fright props uses in their little "fanny packs", I don't have the model number on me but can post it later , after I go out to the haunt get it.

Ever make it to your haunt?

Any help would be greatly appreciated from anyone who's read this :)

What are you using them for?

Some pow sticks and lights/cash registers (don't require any energy really just the electronic cash drawer) for the ticket booth outside.

It may be crude but I would go with car batteries and a DC to AC inverter. I'm seeing inverters that start out at $35 and car batteries can actually be purchased reconditioned as low as $24. Then you have a charger somewhere where there is power and rotate out the car batteries. Or you could have the first ever solar powered haunted house!

You just make cords long enough to have things out of the way and tied of so they can't be tugged lose.

Chargers are maybe $18 to $30 so the whole one system is about $60 to $90 compared to $249.99 plus shipping and slobering. Car batteries can also be on the car that sits near the ticket booth and is used for fast get aways with all the ticket money. Really it should be a seperate one so you can actually start the car after so many hours. You do need a charger as a car alternator does not recover battery charge past a certain point. Marine batteries or deep cycle are best but they are expensive and batteries just sitting the rest of the year not being maintained will need to be replaced.

Chances are this $249 thing will have problems taking a charge prepping for the second year too. So every year you buy reconditioned/checked or even junk batteries that hold a charge.

Sorry for the delay,.. I forgot to check...
but did tonight . we are using the "harbor freight" 750 watt ones to run our palm sanders on our hayride & also to power our "pow"/ "crackers".
These ones have 2 outlets on them, so if you connected them to a car battery as stated above you could use 2 different props. There is also a smaller one that I think might work better for just 1 porp it's 400 watts, I think.
Hope this helps.

You could go with 12volt motorcycle batteries. The actual length of time wouldn't be that great I don't think. If it is something that doesn't take lots of amps. Or riding lawn mower batteries. You could use all leg strength to carry them in a Hello Kitty back pack!

Or you could hack a wheel chair or special needs bicycle because it is starting to sound like you have special needs! Any rechargeable device and a power supply tranformer from one voltage to another and you have cheaply come up with a portable battery that in most cases was intended to be portable yet might not last so long so it becomes having large quantities of things over one thing that actually weighs something but might last all night.

I have no clue why I couldn't find that bugger!

Thank you Allen!

And since Greg's post I managed to get a decent car battery for the outside ticket booth as well as the smaller batteries for pow sticks. Btw, how often do you find yourself changing the batteries on the pow sticks? I ordered the same ones fright props uses

JB used a deep cycle marine battery, plus recharger, as backup power for his security system, iirc. Is that still viable?

Yep. Pretty much any chain style auto parts store.

keep in mind it takes some time to "recharge" a deep cycle battery because you have to slow charge it...like 24 hours so you might want to buy 2 &swap them back & forth..depending how long & many night s you'll be open in a row... just a thought.

Well, the way JB has it set up, it's an emergency backup power supply, and is configured into the whole system, and is meant never to be used except in the rare case of an emergency, so the charger and battery assembly should be fully operational within 24 hours of the system coming online, and then you should be good for the whole season.

And if it never comes into play? All the better.

ok. I did not realize they would have a 110 power supply at all. We run a very similar as what you have in the diagram to run all our 24 volt lights, controllers, & animations. It has done well for us in the past, the only problem we had was one time the charger got turned accidentally to to the "high" setting, and that's a big no-no with deep cycle batteries.

Where is all the creative alternative energy? I want to see a giant skull on the roof covered in solar panels charging lithium batteries. For extra power it sticks it's tongue out. Or go to an old timey mechanical haunted cash register, lighting done with mirrors lasers and quarts concentrators. Or the whole haunt run by a tesla tower with only pick up coils needed on everything. All you have to do is drill down to bed rock for the ground feed, convert to positive ground wiring and burn some shit up for the few days it takes to harness it back. How about the whole thing is based off of a pyramid, same thing as a tesla tower. Go totally steam punk or ancient or future. Why live in the present? Or run the whole thing on hydrogen? Yeah I know trintium pellets to store regenerative hydrogen are regulated highly by the nuclear regulatory commission but what the hell? We need to have some fun.

I remember as a kid going to some colonial town where everything was like it was in the 1700s the black smith shop, horse shoeing, farming, making potery, making clothes, trading for food, fire places in the homes that were made out of local materials. At the restaurant and gift shop they even had old ladies serving you but, my dad bitched at how that brand new IBM cash register that seemed maybe the most important thing in the several acres. Everything esle was hand made or old crap.

Where is the spectacle, the coolness? Or the subtelty or class? Let's start taking shit to the next level! This is also a reminder of how people were going to museums and towns and art galleries, circuses and shows way before there was an internet.
