Tailgate Power Inverter Questions
Q: My wife wants me to get a TV running at a tailgate, and I am too cheap to buy a generator, and worried about the noise from a rented generator. Can anyone give me advice on what to expect from a power inverter? Specifically:
- Is it a stupid idea to pull the batteries from cars we're not using and bring them for extra power? I see people talking about buying marine or deep cycle batteries to run an inverter, but nobody even discussing my idea, so I assume it's too dumb an idea to even come up.
- A bunch of people talk about running their truck for a few minutes an hour to top off their battery when running an inverter. Is the charger really that efficicent that a few minutes an hour in an idling truck (well, Honda Pilot) can power a TV and dish indefinitely?
Thanks - I know the answer probably is that I should rent a generator, but I really like the idea of a cheap, quiet solution.

I've run a tv and home stereo setup using an inverter and just left the car running for several hours. If you don't like that, just bring jumpers and make sure someone near by will jump you in case you run your battery too low.

Like everything else in life, it depends on the size and age of the battery.
Obviously a brand new large truck battery will handle it better than a 10 year old subcompact.
Bring jumpers in case.

How much time have you spent looking at generators? Pretty sure you could find a portable one with a built-in inverter for < $500 if only powering a TV + dish.

Go to Harbor Freight and buy a little tiny TailGator generator. A little noise, sure, but no worries about running a battery dead. Plus, then you have a way to power the fridge next time the power goes out.

I think the 20% off coupons work on it, so like $90.

I did a Predator engine swap on my little snowblower on tracks. Haven't tested it yet (of course), but really looking forward to throwing some snow with a Honda clone.

Starting the car for five minutes every hour ought to do it. We had a big crew in town for MSU and didn't want to pay $250 a head for tickets and were going to buy a 60" and an HD antenna instead of spending three grand on tickets. A the end of the day, given the weater forecast, most of us tailgated all day at AAGO and cruised over to my house and watched the game. A half dozen or so ponied up $225ish a head to go to the game. They got really, really wet.

This is what I use. No noise, no gas, won't run a crockpot, but will power tv, satellite dish, stereo.

For long tailgates, I have an extra battery ready to go.

One thing to keep in mind is that automotive batteries are designed to provide a lot of charge (but not that much compared to their total capacity) for a very short amount of time, to start your car. They are not designed to drain 75% and then recharge every time you have a tailgate, and doing so may actually shorten their life considerably.
If you really want to do this right, what you want is a deep cycle marine battery. They ARE designed to be drained nearly empty and then recharged over and over again. Also they come in a variety of capacities, so if you want to run a few electrical calculations you can figure out what size battery you need to run your setup for as long as you want.
