A first heated jacket. The clearest power story in the category: ororo publishes capacity and voltage for every pack it sells, so you can work out what…
Watt-hours, not marketing hours
Your heated jacket says 10 hours. Its battery says two.
Independent watt-hour math on heated jackets, vests, gloves and socks — the conversion nobody in this category publishes.

Why this site exists
Every site in this category says it tested twenty jackets. We have tested none, and we say so.
What we do instead is arithmetic, on numbers the manufacturers publish themselves. A battery’s energy is its capacity times its voltage. Its runtime is that energy divided by the watts the garment draws. Makers publish the first half and almost never the second, then advertise the lowest setting’s hours as the headline.
So we run it backwards. A maker that advertises “up to 10 hours” on a 37.6 watt-hour pack has told you its claim assumes a 3.8-watt draw — whether it meant to or not. Put that next to the same pack’s published 18.5-watt delivery ceiling and the shape of the advertising becomes obvious.
Nine competitors were fetched while researching this site. Not one publishes that conversion. It needs no lab, no owned units and no credential — only a calculator and a willingness to show the working. Here is ours.
What won, and what it holds
One winner per roundup, each with the pack converted into watt-hours. Prices are live where the feed has them; where it does not, the button says so rather than showing a number we cannot stand behind.
Most heating zones for the money. More heating elements than anything else at the price, which cuts both ways: the same pack energy is divided further, and Venust…

A heated mid-layer for indoors. Four zones instead of three and a fleece face instead of a shell, trading wind resistance for something you can wear at a desk w…

The five sections
Hub
Heated Jackets
The biggest category and the noisiest claims. We convert capacity and voltage into watt-hours, then into hours at each setting.
Top pick: ororo Men's Soft Shell Heated Jacket
Check price on Amazon#ad No live price available, so we show none. How we are funded.
Hub
Heated Vests
Same core zones as a jacket, less fabric to heat, and it layers under the coat you already own. Usually the smarter first purchase.
Top pick: ororo Men's Lightweight Heated Vest
Check price on Amazon#ad No live price available, so we show none. How we are funded.
Hub
Heated Gloves
The smallest packs in heated apparel, fighting the worst heat loss on the body. Liners are the underrated answer.
Top pick: Gerbing 7V S7 Heated Gloves
Check price on Amazon#ad No live price available, so we show none. How we are funded.
Hub
Heated Socks
One toe element, one 7.4V pack, roughly 16 watt-hours a foot. The simplest arithmetic on the site.
Top pick: SNOW DEER Heated Socks, 7.4V
Check price on Amazon#ad No live price available, so we show none. How we are funded.
Hub
Battery & Power
The conversion nobody publishes: capacity and voltage into watt-hours, watt-hours into hours. Plus the calculator that does it for you.
Top pick: ororo PD 10K Battery for Heated Apparel
Check price on Amazon#ad No live price available, so we show none. How we are funded.
What we will and will not do
Four rules we hold to
We never claim to have worn it
No owned units, no lab, no drain tests, no field use. Every product page says so before it says anything else, because you deserve to know how much weight to give us before you read the verdict.
Every number traces to a source
Capacity and voltage come from the manufacturer's own pages and are linked on every card. Where a maker publishes nothing, the cell reads “not derivable” rather than carrying a plausible-looking guess.
Prices are live or absent
No remembered numbers, ever. The live feed has no prices right now, so every button reads “Check price” instead of showing one.
Every roundup names something to skip
A list that recommends everything on it is not a recommendation. If we cannot find a reason not to buy something, we have not finished looking.
The pages that make the case
Battery & power / Guide
Watts, volts and the number on the label that is not quite true
Volts, amps, watt-hours and the labeling convention that overstates every tool-battery jacket by 11%.
Compare
Heated jacket or heated vest? Three questions decide it
Same pack, same elements, different amount of fabric. Three questions that settle which one you should buy.
Guides
What it costs to run heated clothing
0.71 cents a charge at the EIA average rate. The full table, the space-heater comparison, and the cost that does add up.
Battery & power / Guide
Flying with heated clothing, and the unit mismatch that makes it confusing
The FAA writes the rule in watt-hours; makers print milliamp-hours. The conversion table, and where every pack lands.

How this is funded
Plainly, so you can weigh it
Volt Wool is reader-supported. When you buy through a link here we earn a commission at no extra cost to you — as an Amazon Associate we earn from qualifying purchases. That is the only way this site makes money.
We accept no free product, no sponsored placement and no manufacturer relationships, and no brand has ever seen a page here before it published. Where a link earns us nothing, we say so on the link rather than letting you assume otherwise.
