How this list is chosen: Units with an AC outlet whose maker price is over $1,000 and at most $2,000, ordered by price per watt-hour; units within 5% of the lowest count as equal, and among them those whose outlets run a 1,500 W kettle or microwave come first, then the lower price. Maker prices checked 6 Sep 2026 to 7 Oct 2026; we have not tested these units ourselves.
