Electric blankets, heated throws and mattress pads

Heated blankets, ranked by what they cost to run

Top-rated electric blankets with the watts and the nightly cost printed next to every pick. Eight of the 29 products we track publish a wattage. We print those, and we say plainly who publishes nothing.

We earn a commission on some links here, at no extra cost to you. It does not change what we recommend or the order the picks appear in. How we are funded.

The picks, with the numbers

Ranked on what the maker publishes, not on a score we invented. Tap a row for the full write-up, or go straight to the listing. Cost is 8 hours at the rated wattage and $0.1834/kWh.

What to buy

Three formats that solve three different problems. Each hub carries the published wattage, the cost arithmetic and a top pick you can buy from the tile.

How this site works

Wattage from the maker
Every watt figure on this site is quoted from the manufacturer's own listing and linked to it. Where a maker publishes none, we say so instead of estimating.
A cited electricity rate
0.1834 USD per kWh, the EIA average US residential price for June 2026. Linked under every table that uses it.
Arithmetic shown
Every computed figure shows its working, so you can re-run it with the rate off your own bill instead of trusting ours.
A reason to skip every pick
Every product carries a "skip it if". A roundup where all seven picks are great is a roundup nobody should believe.

No live prices are being served right now, so every buy button reads “Check price” rather than showing a number we cannot stand behind. The full method, including what we refuse to claim.
