Heated jackets, converted into hours

A heated jacket is a battery with sleeves. Here is what the published numbers actually buy you, per setting, with the arithmetic shown.

ororo Men's Soft Shell 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 you are getting instead of taking a marketing number on faith.

#ad Price as of October 17, 2026. How we are funded.

A heated jacket's runtime is its battery's watt-hours divided by the watts the garment draws. Makers publish the first half and almost never the second, then advertise the low-setting hours as the headline. Convert the pack yourself and the gap between the ad and the shift becomes obvious.

The number on the box, and the number on the shift

Every heated jacket sold in the US advertises a runtime. It is usually a single figure, usually preceded by the phrase "up to", and it is usually the lowest setting. That is not a lie — the jacket genuinely will run that long on low — but it answers a question almost nobody is asking. If you have switched a heated jacket on, you are cold, and if you are cold you are not on low.

The honest version of the number takes two lines of arithmetic. A battery's energy is its capacity times its voltage: Wh = (mAh ÷ 1000) × volts. Runtime is that energy divided by the draw: hours = Wh ÷ watts. Nine competitors were fetched while researching this site and not one publishes that conversion, largely because the second input — the watts — is the thing the makers keep to themselves.

So we run it the other way. If a maker advertises hours and publishes a pack capacity, the hours state the draw whether the maker meant them to or not. That inversion is the most useful thing on this page, and you can check every step of it against the sources we link.

What the arithmetic actually reveals

The typical heated jacket ships with a 7.4 V pack somewhere between 4,800 and 5,200 mAh. That is 35 to 39 watt-hours — roughly the energy in a mid-size phone power bank, being asked to make fabric warm against moving winter air.

The packs also publish an output current, usually 2.5 A. Multiply that by 7.4 V and you get about 18.5 watts: the absolute ceiling on what the pack can deliver, no matter what the garment asks for. Divide 38 Wh by 18.5 W and you get just over two hours. That is the floor under every "up to 10 hours" claim in the category, and it is derived entirely from figures the manufacturer publishes voluntarily.

On wattage: ororo publishes no wattage for the garment. It does publish hours for each of the three settings, which states the draw whether it meant to or not.

What we like

  • ororo publishes capacity AND voltage for every pack, which almost nobody else in this category does
  • Per-setting runtime claims rather than one 'up to' number, so the low-to-high spread is visible before you buy
  • Soft-shell cut layers under a work coat without bulk

What we do not

  • No published wattage for the garment itself
  • Three zones only — nothing at the arms or the kidneys
  • The headline runtime figure is the low setting, as it is everywhere

Who this suits

Someone standing still outdoors for two to four hours at a stretch who wants the power figures on the table before buying.

Who should skip it

You need heat for a full eight-hour shift on high. No 38 Wh pack does that, and this one does not claim to.

On wattage: Milwaukee publishes run-time, not watts — but it publishes all three settings, which is more than most of this category manages. The 12/6/3 pattern is a clean doubling of draw at each step. Milwaukee does not state which M12 pack those hours assume, so the resulting wattage is a shape rather than a fixed figure.

On the pack: Sold bare. The live listing title reads "Jacket Only" — no pack and no charger in the box. That is the right buy if you already run M12 and the wrong one if you do not. See [which garments include a battery](/battery/battery-included-or-separate).

What we like

  • Hot-swappable packs — the only real answer to a short runtime is a second battery, and you already have one
  • Genuinely durable shell fabric, built for work rather than for a catalog photo
  • The pack doubles as a tool battery, so nothing in the van is single-purpose

What we do not

  • The 2.0 Ah pack is small by heated-apparel standards once you convert it honestly
  • Jacket-only SKUs ship without a battery, which is easy to miss at checkout
  • Heavier than a soft-shell layer

Who this suits

A trades worker with an M12 kit already in the van, for whom a spare pack costs nothing extra to carry.

Who should skip it

You own no M12 tools. Buying into a tool platform for one jacket is the most expensive route into heated clothing.

On wattage: No published wattage. One 'up to 10 hours' figure with no setting attached, which is the least informative form the claim can take.

On the pack: Venustas ships a 7.4 V pack and advertises up to 10 hours. The capacity varies by SKU and is not published consistently, so treat the watt-hour figure here as approximate and check the listing for the pack you are actually buying.

What we like

  • Dual control is genuinely useful — pocket heat is what you want standing still, core heat is what you want moving
  • Six zones reach the neck, which most three-zone jackets leave cold
  • Detachable hood, so it layers under a shell

What we do not

  • No published wattage and no per-setting runtime, so the power story is one unqualified number
  • Pack capacity is not stated consistently across SKUs sold under similar names
  • More zones on the same pack is not more heat — it is the same heat spread thinner

Who this suits

Someone who wants pocket heat and core heat on separate switches and is buying on coverage rather than runtime.

Who should skip it

You want to know what you are buying in watt-hours before you buy it. On this jacket you cannot, and we are not going to pretend otherwise.

On wattage: No garment wattage is published, but this pack states its own delivery figures: "up to 24W input" and "30W output". The 30 W output is a ceiling for charging devices rather than a figure any ororo garment draws — inverting the 13.5-hour claim against about 50.9 Wh gives roughly 3.8 W, which is the draw that claim actually assumes.

On the pack: Worth reading the voltage twice. This pack's own product page gives "7.27V", while ororo's battery guide lists the PD 7K at 7.4 V. At 7.27 V the 7,000 mAh works out to about 50.9 Wh; at 7.4 V it is 51.8 Wh. We use the figure printed on the product page itself and note the 2% disagreement rather than quietly picking the flattering one.

What we like

  • The largest ororo pack actually purchasable here — roughly 43% more energy than the Mini 5K that ships with several ororo garments
  • ororo publishes a real certification list, with UL2056 printed on the casing
  • USB-C in and out at 30 W means it doubles as a fast phone bank
  • Three-hour full recharge is quick for this capacity

What we do not

  • ororo's own two pages disagree on the voltage — 7.27 V on the product page, 7.4 V in the battery guide
  • No watt-hour figure printed for this pack, unlike ororo's Mini 5K and PD 5K pages
  • The larger PD 10K exists in ororo's lineup but is not sold through this retailer
  • Costs a meaningful fraction of a whole garment, which is the usual complaint about spare packs

Who this suits

An ororo owner whose garment shipped with a Mini 5K and who has discovered that the battery, not the jacket, is what ends their day.

Who should skip it

Your garment already ships a PD 5K or larger and your days are short. The jump from 37.5 Wh to 50.9 Wh is real but it is not transformative.

What we like

  • Passes as ordinary clothing, which matters if you are warming up on a touchline rather than a job site
  • Cotton-blend face is more comfortable against skin than a shell fabric
  • Cheaper entry point than a full heated jacket

What we do not

  • No wind or water resistance worth the name — it is a sweatshirt with a battery
  • The same missing wattage figure as the rest of the Venustas line
  • Pullover cut makes the battery pocket harder to reach

Who this suits

Someone cold indoors or in mild outdoor conditions who wants heat without the outerwear silhouette.

Who should skip it

You need to stand in wind. Put a shell over it, or buy a jacket.

What we do not

  • No published output current, so the delivery ceiling is unknown
  • A pack this large deserves a certification you can look up, and this one's is not clearly stated

Who this suits

Someone whose jacket genuinely dies mid-shift and who has already weighed the trade-off.

Who should skip it

You are not comfortable buying an unverified capacity claim from a third party. That is the right instinct and we share it.

Spec sources: Amazon — third-party 7.4V 16000mAh heated apparel pack · ororo — Heated Apparel Battery Guide (capacity, voltage and output for every pack)

Zones are a spending decision, not a warmth decision

A six-zone jacket is not warmer than a three-zone jacket on the same pack. It is the same energy divided across twice as many elements. Whether that is better depends entirely on where you are cold: a neck element is worth a great deal to someone standing in wind, and worth nothing to someone whose collar is already zipped.

This is the single most common way buyers overpay in this category. Zone count is printed in large type because it is easy to compare and impossible to argue with. Watt-hours are printed nowhere, because they invite exactly the comparison we are making here. If you want the full version of this argument, heating zones explained works through what each zone is for and which ones are decoration.

The arithmetic

Watt-hours, and what they buy

Energy is capacity times nominal voltage. The ceiling draw is the pack’s own published output current times its voltage. The implied draw runs the maker’s advertised hours backwards. Nothing here is measured — check our working.

“Not derivable” means the manufacturer does not publish the figure the sum needs. We leave it blank rather than estimating it, borrowing a number from a similar model, or rounding one into existence. These are ceilings, not promises: cold, wind, movement and pack age all push real runtime below them. Run your own numbers.

The three questions worth answering before you buy

  1. How long do you actually stand still? A two-hour touchline is a different purchase from an eight-hour outdoor shift. The second cannot be solved by any single pack in this category — it is solved by a spare, which is why the tool-battery jackets look better the longer your day is.
  2. Is it your core that is cold, or your hands? A heated jacket does nothing for hands. Buying one to fix cold fingers is the most expensive mistake in this category, and heated gloves or liners are the cheaper, correct answer.
  3. Do you already own a tool battery platform? If you have M12 or 20V MAX packs in the van, a tool-platform jacket turns the runtime problem into a non-problem. If you do not, buying into a platform for one garment is the most expensive route there is. The M12-versus-20V comparison covers what each platform is worth here.

In heated jackets

Questions

Frequently asked

How long does a heated jacket actually last on high?
For the common 7.4 V, 5,200 mAh pack, the maker's own claim is two to three hours on high. That figure lines up with what the pack's published output current allows: 2.5 A at 7.4 V is about 18.5 watts, and 38.5 watt-hours divided by 18.5 watts is a little over two hours. The 8-to-10-hour figure in the advertising is the low setting.
Why do heated jackets advertise 'up to 10 hours'?
Because on the lowest setting they will do it, and 'up to' is doing the work. It is not false. It is just the answer to a question you are unlikely to be asking, because you switched the jacket on to be warm rather than to be slightly less cold for a long time.
Does a jacket with more heating zones keep you warmer?
Not on the same battery. More zones means the same watt-hours divided across more elements. Extra zones are worth paying for when they cover somewhere you are genuinely cold — the neck is the usual one — and not otherwise.
Can I use a bigger battery with my heated jacket?
Usually, if the connector matches and the voltage is the same. A larger pack at the same voltage runs the same elements for longer; it does not make them hotter. That is the correct fix for 'it dies before my shift does' and the wrong fix for 'it is not warm enough'.
Is a heated jacket or a heated vest better?
For most buyers the vest, because it puts the same energy into the same core zones while heating much less fabric, and it layers under a coat you already own. Sleeves matter if your arms are genuinely cold or if you need the jacket to be your outer layer. We work through the whole decision in the jacket-versus-vest comparison.
