You can get AA powered LP detectors at WalMart. I just bought one last
fall. In fact their website lists a dual pack. LP and smoke det. Both battery
powered. First Alert SCO403 Alarm Combination Pack - Walmart.com
They also list the LP alarm alone for $18. That's the one I bought last
Also, a 1000 watt genny is PLENTY for battery charging!!!
This has been discussed here often and at length.
As long as you aren't wanting to run your roof AC or microwave a 1000 watt
genny is huge.
If you have a 30 amp charger--
Amps times Volts = Watts. remember we're talking about charging 12v batts.
30 amps X 12 volts = 360 watts.
Allow 20% for heat loss in the charger and you are still
WAY below your 1000 watts genny max output.
A 1000 watt genny is probably only rated 1000 for brief peak loads.
Max continuous load is more likely in the 750 - 800 watt range but you
are STILL in good shape.
OK on re-reading your post I see the charger says it requires 7 amps input??
That's a lot. Remember battery load is only highest when batteries are
seriously discharged and that load will go down fairly rapidly as batteries
charge. I still believe the 1000 is enough to do the job for you--
especially if you don't let your batteries get too discharged first.
Remember for best battery life you want to re-charge when they are
50% discharged or sooner!
I use a 25 amp output automatic charger and my 2000 genny is positively
loafing. I wish I had a lighter 1000 myself!
Get the smaller, lighter, slightly cheaper 1000 watt. I wish I had!
