It's getting hot in Texas and we're planning on anchoring in a cove tonight. Found one of these Schumacher-PP-2200 power supplies on sale at Walmart for $60

http://www.amazon.com/Schumacher-PP-2200-Portable-Outdoor-Power/dp/B002CG001E/ref=cm_cr_pr_product_top


To help move air around we picked up one of these O2 O2-Cool Model 1054 10" Indoor/Outdoor Fan:

Anyone try these yet? I figure I'll give them a shot, if they don't work out I can return them.

I got both and use them all the time. The power dome I got at Costco years ago. It is very useful. I also got the cooling fan at WM on sale. I got a little bigger unit and it really helps to keep things cool down below.

Peter,
Yes I have the fan and its pretty good. It takes about an Amp, so I usually only run it for a few hours. In full sun, however it will run directly off my solar panel.

The 22AH sealed battery is fantastic at 18 pounds, and a good solution if you want to save your main boat battery. If you discharge it 1/2 way, you can pretty much recharge it with an 18-20W solar panel in a day if you have full sun.

The downside I see is the inverter - mine wastes about 400 milliamps when it is idling without any load. While 0.4A doesn't seem like much, forgetting to switch it off while running it on your power supply for a couple of days would completely discharge the battery.

While wet cells are usually severely harmed by total dischange, can you completely run this battery down without a problem?

Interesting. So would this power a 120V power tool such as a drill or circular saw? Suppose you powered a 60 Watt bulb with it. How long would it last?

I have two of the fans and they work great. They are 12V. We ran the pair on a camping trip in the Keys using the boat battery and they seemed to be spinning as fast on the 7th day as they were on the first. Mine had the ability to run off 'D' cells.

The 110VAC outlet can supply up to 400 Watts. At 110V that would be about 3.6A. If you were using a full 400 Watts, the 12VDC battery would be supplying 36A. Being a 22 AH source, you'd run out of power in under 1/2 an hour if you were running at 400W. But if you were using a drill, you could probably run it for 10-15 minutes total time.

For a 60W light bulb, you'd be using about 0.5A @ 110 VAC, or 5A at 12VDC. You could run at that rate for about 4 hours until the battery quit.

But now, imagine if you replaced a 60W incandescent bulb with a 13W compact fluorescent bulb (CFL). You would pull about 120 mA AC at 110 VAC, or about 1.2A at 12 V. The CFL would run for about 18 hours till the battery went dead.

You could probably use the 13W CFL for about 9 hours.
