What it costs to run heated clothing
The electricity is almost free. Nobody publishes the figure, so here it is — along with the cost that genuinely does add up.
By Scooter M. · Published August 31, 2026
Charging a 38.5 watt-hour heated jacket battery costs about 0.7 cents at the US average residential rate of 18.34 cents per kilowatt-hour. Even charged daily all winter that is under a dollar a season. The cost that matters is battery replacement, not electricity.
The arithmetic
Electricity is billed in kilowatt-hours. A heated clothing battery is measured in watt-hours — a thousandth of the same unit. So the calculation is short:
Seventy-one hundredths of one cent. That is the whole answer, and it is why nobody publishes it — there is no marketing value in a number that small, and no reason for a buyer to worry about it.
| Pack | Watt-hours | Cost per charge | Charged daily, Nov-Mar (151 days) |
|---|---|---|---|
| Heated sock or glove liner pack | 16.3 Wh | 0.30 ¢ | 45 ¢ (per foot or hand) |
| Gerbing 7V glove pack | 23.8 Wh | 0.44 ¢ | 66 ¢ per hand |
| Milwaukee M12 2.0 Ah | 21.6 Wh | 0.40 ¢ | 60 ¢ |
| ororo Mini 5K | 35.5 Wh | 0.65 ¢ | 98 ¢ |
| ororo B19G (standard jacket pack) | 38.5 Wh | 0.71 ¢ | $1.07 |
| ororo PD 10K | 75.1 Wh | 1.38 ¢ | $2.08 |
Charging is not perfectly efficient, so real wall draw is somewhat higher than the pack's capacity — but even allowing generously for that, every figure here stays trivially small.
The most expensive line in that table is two dollars and eight cents, for the largest pack in the category charged every single day from November through March. For context, that is less than one cup of coffee for an entire winter of daily use.

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.
The numbers
- Energy
- 38.5 Wh
- Pack
- 7.4 V, 5,200 mAh (ororo B19G)
- Published output
- 2.5 A
- Heat zones
- 3
- Maker's runtime claim
- 8-10 h low / 5-6 h medium / 2-3 h high
- Heat zones
- Left and right chest, mid-back
- Settings
- Three, cycled from a single chest button
- Care
- Machine washable with the battery removed
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.

ororo PD 7K Rechargeable Battery for Heated Apparel
7,000 mAh of LG cells with a published 13.5-hour claim and a six-mark certification list — the biggest step up available to an ororo owner, because the larger PD 10K is not sold through this retailer.

The numbers
- Energy
- 51.8 Wh
- Capacity
- 7,000 mAh at 7.27 V — about 50.9 Wh
- Published output
- 30 W out, up to 24 W in
- Recharge
- Fully recharged within 3 hours
- Certification
- UL2056, CE, FCC, CB, WEEE, CA65 per ororo
- Heat zones
- Not applicable — this is a battery
- Settings
- Garment-dependent
- Care
- Not washable — remove before laundering the garment
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.
Spec sources: ororo — 7000 mAh PD 7K Rechargeable Battery ("7,000mAh" with "premium LG cells"; voltage given as "7.27V" on this page against 7.4 V in ororo's battery guide; "up to 24W input"; "30W output"; "fully recharged within 3 hours"; "up to 13.5 hours of heat"; "UL2056, CE, FCC, CB, WEEE, CA65 certified"; "1 USB-C Port, 1 USB-C Cable, 1 DC Port"; NTC sensor) · ororo — Heated Apparel Battery Guide (capacity, voltage and output for every pack)
SNOW DEER Heated Socks, 7.4V
The reference point for the category, and the rare heated product whose pack capacity is actually published — on the replacement-battery listing, if not on the sock's own page.
#ad Price as of October 17, 2026. How we are funded.
The numbers
- Energy
- 16.3 Wh
- Pack
- 7.4 V, 2,200 mAh per sock
- Element
- Toe box
- Wash
- Machine, battery out
- Heat zones
- Toe box only
- Settings
- Three
- Care
- Machine washable with the battery removed
On wattage: No published wattage. The pack capacity is published on SNOW DEER's own replacement-battery listing, which gives you the energy figure even though the sock page does not.
What we like
- The element sits over the toes, which is the only place foot heat actually matters
- Replacement packs are cheap and easy to find, which extends the useful life a long way
- Machine washable, unlike most heated gloves
What we do not
- Cuff packs are visible above a low boot
- About 16 Wh a foot is not much energy
- No wattage published
Who this suits
Hunters, ice anglers, spectators — anyone standing still on frozen ground.
Who should skip it
Your boots are already tight. A sock with an element and a cuff pack needs room you may not have.

The comparison people actually want
The reason this figure is interesting is not the number itself but the contrast. Heated clothing is often mentally filed alongside space heaters, and the two are not remotely in the same category.
A heated jacket draws single-digit watts. A domestic space heater draws around 1,500 watts. That is roughly two orders of magnitude — running a space heater for one hour uses more electricity than charging a heated jacket every day for a month.
Which is a genuine argument for heated clothing that has nothing to do with warmth: heating the person rather than the room is dramatically less energy, because you are not also heating the air, the furniture and the walls. The heated garment's small battery is a feature of the approach, not a limitation of the technology.
The cost that does add up
Batteries. Lithium packs lose capacity with every charge cycle, and after two or three seasons of regular use the drop is noticeable. A replacement pack costs meaningfully more than the electricity you will put through it over its entire life — by orders of magnitude.
So the real running cost of heated clothing is a pack every few years, and the way to reduce it is to look after the one you have:
- Store at around half charge in the off-season. Stored full or stored flat ages the cells faster.
- Store indoors, not in a freezing garage or a hot car.
- Charge at room temperature. Cold charging is hard on lithium, and some packs refuse it outright.
- Run the lowest setting that works. Fewer full cycles is fewer cycles of wear, and it is also the only free way to extend a day's runtime.
- Buy spares while your model is current. Replacement packs vanish from the market before garments wear out, and a garment with no available pack is finished regardless of its condition.
Battery troubleshooting covers pack care and how to tell a genuinely aged pack from a dirty connector, which is the diagnosis people get wrong most often. Charging and pack care covers charge times and the storage habits that decide how many winters you get.
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.
| Product | Capacity | Volts | Energy | Ceiling draw | Shortest runtime | Implied draw at the claim |
|---|---|---|---|---|---|---|
| ororo Men's Soft Shell Heated Jacket | 5,200 mAh | 7.4 V | 38.5 Wh | 18.5 W | 2h 05m | 15.4 Wat 2.5 h high |
| ororo PD 7K Rechargeable Battery for Heated Apparel | 7,000 mAh | 7.4 V | 51.8 Wh | 22.2 W | 2h 20m | 3.8 Wat 13.5 h maker's headline claim, with ororo apparel |
| SNOW DEER Heated Socks, 7.4V | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | 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.
Frequently asked
- How much does it cost to charge a heated jacket?
- About 0.7 cents for a standard 38.5 watt-hour pack, at the US average residential rate of 18.34 cents per kilowatt-hour. Charged every day from November through March that is about $1.07 for the whole season.
- Is heated clothing cheaper than a space heater?
- By roughly two orders of magnitude. A heated jacket draws single-digit watts; a domestic space heater draws around 1,500. Running a space heater for an hour uses more electricity than charging a heated jacket daily for a month.
- What is the real running cost of heated clothing?
- Replacement batteries, not electricity. Lithium packs lose capacity with use and typically need replacing after two or three seasons of regular use. That cost dwarfs the electricity by a wide margin.
- How do I calculate what my heated jacket costs to charge?
- Divide the pack's watt-hours by 1,000 and multiply by your electricity price per kilowatt-hour. If you do not know the watt-hours, they are capacity in amp-hours times nominal voltage — our runtime calculator will work it out.
- Does running a heated jacket on high cost more?
- It empties the battery faster, so you charge more often — but each charge still costs a fraction of a cent. The real cost of running high is charge cycles, which shorten the pack's life, rather than the electricity itself.
