So, err....
Battery to Inverter to Surge Protector?

[Matt Attallah]

I'd have to agree with that. But what is this setup for? Can't be for anything big due to the FIRST batteries you are using...

???

Never mind - found out it's for the X-Box platform...

How long where you able to play the TV and X-Box for? I'm sure it sucked ampers like no tomorrow...

One number I had heard was 4 hours.

Yeah, Titus says 4 hours.

I had an old ghetto (one zipper broken) rolling backpack that I was going to trick out.
At the beginning of the summer, I thought I would have a good summer job ($1000-1500 for the whole summer, 25-30 hours per week) and an extra laptop (If I did better than a 1500 on SAT). Unfortunately neither came true (my score was only a 1460) but I will tell you my idea anyways.
In my backpack would be a FIRST battery (or maybe 2) hooked up to a recharger and an inverter (a switch with some simple circuits would tell it when to use the recharger). It could also be plugged in, when the stereo would run on AC power and the battery(ies) would be recharged. The Inverter would then be connected to a power strip, and connected to the power strip would be a 100 watt subwoofer/satellite stereo (the satellites would go in the zipper water bottle holding sections). There would also be a laptop adapter and a place to put my cd player and ipod.
It is a pretty pimp idea, but all of it is hypothetical, except for the crappy backpack. I was going to take it to nats and roll it around with loud music. Hopefully I will see someone who used this idea.

If you're connecting a battery to your laptop, why not skip the inverter/adapter and just use a transformer/regulator?

your laptop typicly will require more than just 12 V DC to run, my laptop personally requires about 14.5 to register and to charge but the adapter runs at around 19 (through testing using, get this, AA 2.2 amp batteries). There may be some laptops that would use less but the cost of the regulators to regulate down to 11 V DC or Lower at the laptops required amperage could be more expensive and more troublesome than the inverter, plus with the inverter you could run more stuff.

$0.02

Really the most expensive part of all this, besides the obvious (the laptop) is the inverter and the sat link. the battereies could ccost, what, $20? and the inverter $30->$80->$140(depending on the size). Look around on ebay and find stuff around you at nearby stores you could still get your idea out. The circuitry you're talking about is VERY simple. If you would like a better Idea of how to do this PM me I could help.

Yeah.. they sell them at Walmart. for like 20 bucks... :rolleyes:

Same concept, cruddy looking speakers though. Prolly all tinny and what not. lol

Cool idea and setup. I should bring this up for our next trip to a competition. I remember some people wanted to play gamecube on the bus to nationals, but there was the issue of either the power or A/V cables being hard wired (and 90% of the bus, including my self, whom would rather not watch the same 4 people play SSBM).
