Our top pick in heated jackets
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.
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.

#1 · A first heated jacket
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.
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. Its own 'up to 8 hours on the REDLITHIUM 2.0' figure plus the pack's published capacity are enough to derive the draw that claim assumes.
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.
More heating elements than anything else at the price, which cuts both ways: the same pack energy is divided further, and Venustas does not publish the wattage that would tell you by how much.
Neck, left and right chest, mid-back, both hand pockets
Settings
Three, with the upper and lower circuits controlled separately
Care
Machine washable with the battery removed
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.
The only route to genuinely long runtime is a bigger pack, and this is the largest one in the category with a published capacity — roughly double the energy of the pack most jackets ship with.
Not washable — remove before laundering the garment
On wattage: The 17-hour claim is a pack-level figure. Divide the pack's energy by 17 and you get the draw that claim assumes, which is far below what the pack can deliver at full output.
What we like
By far the largest published capacity in heated apparel, and the capacity IS published
USB-C in means one cable for the pack and the phone
Still comfortably inside the FAA's 100 Wh carry-on threshold once you convert it
What we do not
Heavy and bulky in a chest pocket next to a 2,200 mAh accessory pack
Only worth buying if your garment's connector matches
The 17-hour claim, like all of them, describes the lowest setting
Who this suits
Someone whose actual complaint is that the jacket dies before the shift does, and who would rather fix it with energy than with a warmer setting.
Who should skip it
Your problem is peak warmth rather than duration. A bigger pack runs the same elements for longer; it does not make them hotter.
USB-C matters more than it sounds: the pack recharges from the same brick as your phone and your laptop, which removes the proprietary-charger failure mode entirely.
On wattage: No published wattage. ororo does publish the pack's capacity, voltage and output current, which is three more useful numbers than most of this category prints.
What we like
USB-C recharge kills the proprietary-brick problem, which is the most common way these packs get abandoned in a drawer
Puffer insulation means the vest is warm before you switch anything on
Published capacity, voltage and output amps — unusually complete for this category
What we do not
Puffer bulk is real under a fitted coat
Four zones on a 37.6 Wh pack is a thinner spread than three zones on the same energy
Still no wattage figure
Who this suits
Someone who travels with the vest and does not want a second charger in the bag.
Who should skip it
You need it to disappear under a slim shell. It will not.
Venustas puts larger carbon-fiber panels over more of the torso than most rivals, and publishes less about the power behind them than most rivals — you are buying coverage on trust.
The largest capacity on this page by a wide margin, and the one we are most careful about: a third-party pack with a big number on it deserves more skepticism than a brand pack with a small one.
On wattage: No published wattage and no published output current, which means we cannot even state the pack's own delivery ceiling.
On the pack: Third-party capacity claims are not independently verified by anyone, including us. The watt-hour figure below is arithmetic on the seller's own numbers — it is not a measurement of the pack.
What we like
If the claim holds, roughly three times the energy of the pack most jackets ship with
An LED display means you know where you stand before you go out
Adapter cables cover the common garment connectors
What we do not
Third-party capacity claims are unverified by definition
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.
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.

No claim published
“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
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.
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.
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.
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.
