I had a 1000w or 1400w installed on my suburban which I pretty much lived in while out on wells. Well in Feb 2021 that freeze happened, I had to leave to go offshore and my wife was stuck without power for 4 days, no fireplace, so with that in mind I bought us two jackery 1000 power stations, it won’t run my angle grinder but it powers my little Goodyear air comp which was really my only need plus it can run lower powered stuff like a mini electric heater just in case! Plus it’s portable and idling a 6.2L to power anything seems like burning money.
