My favorite one is Costco's. 18Ah battery, jumpstarter, area light, compressor, charges from house current and won't overcharge from that source (the manual says, though, to be careful not to overcharge it from 12V sources). I've used it several times instead of dragging out my jumper cables. And I can run my amateur HT or my cellphone off of it for at least a week continuously.

No affiliation other than a Costco membership.
