A heated glove liner is a thin knit glove with an element and a small 7.4 V pack — roughly 16 watt-hours per hand — worn inside a glove you already own. It keeps your existing glove's insulation and fit and, crucially, your dexterity, which is the reason liners stay on hands when heated gloves come off.
The argument for the smaller battery
On paper the liner loses. About 16.3 watt-hours per hand — a 7.4 V, 2,200 mAh pack — against 23.8 for the largest heated glove here. Less energy, no wind protection, no insulation of its own. A spec sheet would rank it last.
The spec sheet is measuring the wrong thing. A heated glove has to solve two problems: make your hands warm, and let you keep using them. Heated gloves are good at the first and poor at the second, and a glove you take off to pick up a screw stops solving either.
The liner sidesteps it. Your existing glove supplies insulation, weather protection and a fit you have already proved. The liner adds heat. And because it is thin, you can leave it on when the outer glove comes off — which is precisely the moment your hands are most exposed.

SAVIOR HEAT Heated Glove Liners
The most underrated format in heated apparel: a thin heated liner under your existing work glove beats a bulky heated glove for anyone who has to actually use their hands.
#ad No live price available, so we show none. How we are funded.
The numbers
- Energy
- 16.3 Wh
- Pack
- 7.4 V, 2,200 mAh per hand
- Thickness
- Liner — fits inside a work or ski glove
- Touchscreen
- Yes, per the listing
- Heat zones
- Back of hand and fingers
- Settings
- Three
- Care
- Hand wash with the battery out
On wattage: No published wattage. Small packs and a small element area, so the runtime spread between settings is wide.
On the pack: Liner packs in this class are 7.4 V, 2,200 mAh. The capacity is stated on the replacement-pack listing rather than on the glove listing.
What we like
- Fits under gloves you already trust, so you keep your grip and your dexterity
- Cheapest route into heated hands by a wide margin
- Packs are small enough to live in a coat pocket
What we do not
- Smallest packs here — about 16 Wh a hand, and the arithmetic on that is unforgiving
- No wind or water protection of their own
- The fit under a tight glove can be a squeeze
Who this suits
Trades workers, photographers, anyone who has to do something with their fingers in the cold.
Who should skip it
You want long runtime. This is the smallest energy budget on the site and it shows.

SAVIOR HEAT 7.4V Heated Gloves
A competent middle option: warmer than a liner, less bulky than the Gerbing, and with the same missing wattage figure as everything else in the category.
#ad No live price available, so we show none. How we are funded.
The numbers
- Energy
- 16.3 Wh
- Pack
- 7.4 V per hand
- Element
- Doubled in the thumb and index finger
- Shell
- Water-repellent insulated polyester
- Heat zones
- Back of hand, with the element doubled in the thumb and index finger
- Settings
- Three
- Care
- Spot clean
On wattage: No published wattage.
On the pack: 7.4 V packs. Capacity is stated on the replacement-pack listings for this class rather than on the glove page.
What we like
- Doubled element in the thumb and index finger, which is where cold bites first
- The insulated shell does real work before the battery is switched on
- Widely stocked, so replacement packs are easy to find
What we do not
- No wattage published
- Middling capacity
- Bulkier than a liner without being as warm as a mitten
Who this suits
Someone who wants one pair of heated gloves for general winter use.
Who should skip it
You are stationary for hours in hard cold. Mittens hold heat better than fingers do.

Gerbing 7V S7 Heated Gloves
Two 3,400 mAh packs is the largest per-hand energy figure on this list, and it still will not get you a full day on high — which tells you most of what you need to know about heated gloves.
#ad No live price available, so we show none. How we are funded.
The numbers
- Energy
- 23.8 Wh
- Pack
- 7 V, 3,400 mAh per glove
- Packs included
- Two, plus a dual charger
- Element coverage
- Full finger
- Heat zones
- Back of hand and along all five fingers
- Settings
- Three
- Care
- Spot clean only
On wattage: Gerbing publishes no wattage. It does publish pack capacity and voltage, which is more than most glove makers do and enough for the energy half of the arithmetic.
What we like
- The element runs the full length of the fingers, not just across the back of the hand
- Largest published per-hand capacity here
- Ships with both packs and a dual charger, so there is nothing else to buy
What we do not
- No published wattage, so the runtime half of the sum is unavailable from Gerbing alone
- Bulky enough that fine work is awkward
- Expensive
Who this suits
Motorcyclists and anyone whose hands sit in moving air, where the heat is fighting convection rather than still cold.
Who should skip it
You need dexterity. These are warm mitts with fingers, not working gloves — look at liners instead.

SAVIOR HEAT Heated Ski Mittens
Physics before electronics: fingers sharing one chamber lose less heat than fingers in separate ones, so a mitten gets more warmth out of the same watt-hours than a glove does.
#ad No live price available, so we show none. How we are funded.
The numbers
- Energy
- 16.3 Wh
- Pack
- 7.4 V per hand
- Format
- Mitten
- Use
- Skiing, stationary outdoor cold
- Heat zones
- Back of hand, across all fingers
- Settings
- Three
- Care
- Spot clean
On wattage: No published wattage.
On the pack: 7.4 V class packs.
What we like
- Mitten geometry keeps fingers warmer at any given power level
- Better for circulation-limited hands than a fingered glove
- Same pack family as the rest of the SAVIOR line
What we do not
- You cannot do anything precise in them
- No wattage published
- Getting them on and off around a pole strap is a fiddle
Who this suits
Skiers and anyone whose hands go numb regardless of what they wear.
Who should skip it
You need to hold a tool, a camera or a phone.

Gerbing 7V Women's S7 Heated Gloves
The same electronics as the men's S7 on a last cut for narrower hands, which matters more than it sounds: a heated glove that fits badly heats air instead of skin.
#ad No live price available, so we show none. How we are funded.
The numbers
- Energy
- 23.8 Wh
- Pack
- 7 V, 3,400 mAh per glove
- Sizing
- Women's last, from XS
- Element coverage
- Full finger
- Heat zones
- Back of hand and all five fingers
- Settings
- Three
- Care
- Spot clean
On wattage: No published wattage; capacity and voltage are published.
What we like
- A genuine women's last rather than a shrunk men's glove
- Full-finger element, which the smaller heated gloves usually drop
- Largest published per-hand capacity in its size range
What we do not
- No wattage published
- Expensive
- Still bulky for fine work
Who this suits
Anyone whose hands are too narrow for a men's small, which is a real and badly served group.
Who should skip it
You want dexterity — the liner is the better answer.

What 16 watt-hours per hand actually is
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 |
|---|---|---|---|---|---|---|
| SAVIOR HEAT Heated Glove Liners | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | No claim published |
| SAVIOR HEAT 7.4V Heated Gloves | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | No claim published |
| Gerbing 7V S7 Heated Gloves | 3,400 mAh | 7 V | 23.8 Wh | Not published | Not derivable | No claim published |
| SAVIOR HEAT Heated Ski Mittens | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | No claim published |
| Gerbing 7V Women's S7 Heated Gloves | 3,400 mAh | 7 V | 23.8 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.
These are the smallest energy figures on this site, and we would rather put them in front of you than bury them. No liner maker publishes the element's draw, so the exact runtime is not derivable and we mark it that way rather than estimating it. What the table does tell you is the ceiling: you cannot get more energy out of the pack than is in it, whatever the listing claims.
It also tells you the fix. Spare packs for this class are inexpensive and small enough to live in a coat pocket, and two packs a hand doubles your day for a fraction of what a warmer glove costs.
When a liner is the wrong answer
- Motorcycling. Constant convective loss from moving air needs sustained output and real wind protection. A full heated glove with a bigger pack and a proper shell is the right tool.
- Long stationary cold with no dexterity requirement. A heated mitten wins outright here — fingers in one shared chamber lose less heat than fingers in five separate ones.
- Gloves that already fit snugly. There is no room, and forcing it restricts circulation, which is a net loss.
- Circulation conditions where compression is a specific concern. See heated gloves for arthritis and Raynaud's, and talk to your doctor about your own situation.
What we would skip, and why
- A liner bought to be worn on its own
- A liner has no wind protection, no water resistance and almost no insulation. Its entire design premise is that something else is providing those. Worn alone in real cold, it is a thin knit glove with a battery, and about 16 watt-hours will not fix that.
- A liner squeezed into a glove that already fits snugly
- Compression is the enemy of warm hands. A liner forced into a tight glove restricts circulation, and restricted circulation makes your fingers colder than the element can make them warm. If your gloves are already close-fitting, buy the next size up or buy a heated glove instead.
Our criteria, and what we did not do
- Dexterity treated as a first-order criterion, because a heated glove that comes off is worth nothing.
- Element coverage recorded — back-of-hand only versus full-finger changes what the product does.
- Published pack capacity converted at nominal voltage, sourced from the replacement-pack listings where the glove page is silent.
- Replacement pack availability weighted, since the pack fails long before the liner does.
- We have not worn any of these. See how we do this.
We have not worn, tested or owned any of these products, and we say so on every page rather than in a footer. What we do instead is compile the published specifications and do the arithmetic. The full method.
Frequently asked
- Are heated glove liners better than heated gloves?
- For anyone who needs to use their hands, usually yes. A liner keeps your existing glove's insulation and fit plus your dexterity, and it stays on when the outer glove comes off. For motorcycling or long stationary cold, a full heated glove or mitten is warmer.
- How long do heated glove liners last?
- The packs in this class are 7.4 V and 2,200 mAh, which is 16.3 watt-hours per hand. Makers do not publish the element's draw, so we mark the exact hours not derivable rather than guessing. Spare packs are cheap and are the practical answer.
- Can you wear heated liners under ski gloves?
- Yes, if there is room. That is one of the best uses for them — the ski glove handles wind and water, the liner handles heat, and you keep a fit you have already proved. If your gloves are tight, size up rather than forcing it.
- Do heated glove liners work with touchscreens?
- Most are made with conductive fingertips and are listed as touchscreen-compatible. It is worth confirming on the specific listing, because it is exactly the sort of feature that varies between similar-looking models.
- Are heated liners warm enough on their own?
- No, and they are not meant to be. A liner has no wind protection and almost no insulation — the design assumes an outer glove is providing both. Worn alone in real cold it is a thin knit glove with a battery.
