Beware, you need to regularly maintain it too (hopefully it does a weekly starter test, and it probably needs yearly oil changes). I didn't check mine, and found the battery charger had failed at about 1 am when my wife had a flight out that morning. That was fun.
(We don't have everything on the generator, so it's not as effective as yours, our utility wiring is actually pretty fragile, and our well pump is one of the things not on the generator, buying a portable genrator for that seems to have helped, but I did have to roll it out a week ago)
It would have cost twice as much to run everything with the generator, and that isn't really necessary, so it's a smaller one.
I worried about the battery being dead and no way to hand crank the generator, so I made sure that the generator could be started from a car battery or one of those zap-o-matic car jumpstarters. (I bought one of those last year, and had occasion to try it out on my stone dead car battery last month - it worked great!)
Every time.
Fortunately, after about 6 weeks or so, the market forgets I did a transaction, and things start moving my way. I'm forced to be a long term investor.
Vijay, is that you?
Hmm. Is this something I can buy at Home Depot or something?
I know that purchase was effective, because a week after it was installed there was a big storm and power went out everywhere except my neighborhood. Just having a generator successfully wards off power failure, you never have to actually turn it on.
I submit this is objective proof that I am living in a simulation and none of you exist, you're just artifacts of the simulation.
