There is a really good gennie here, which runs the house and the shop, but it gives me a headache to hear it days on end. Being here is the first place I ever had access to a gennie, and I could live better with out it.
If I remain here longer I will have to build a portable gennie shed, to be out of sight in power grid days and be in sight with the gennie in it, to tone down that dull thump of a engine, or some how make it sound like a Harley
I can sort of deal with that sound, but I have no harley.
I keep a car radio just for this reason, and have one of those battery jump start packs. That contains a 18Ah (Ah = Amp hour) battery, much like a bike battery, a computer back up battery, or a golf cart/lawn mower battery.
It will run 1 amp 18 hours, or 18 amps 1 hour.
With a few moments of tinkering you could use a pc back up battery in a storm for 12dcv as well. You can charge it back up with any car in around 10 minutes, or if you have a gennie charge it while you use it, with it's own acv adapter or a 12 volt maintainer.
