Gerbing 7V S7 Heated Gloves: the most energy per hand, and it is still not much
We have not worn these. The published packs are the largest in heated gloves, which makes the arithmetic on them the most instructive on the site.

The Gerbing S7 ships two 7 V, 3,400 mAh packs — 23.8 watt-hours per hand, the largest published figure in heated gloves. The element runs the full length of the fingers rather than stopping at the back of the hand. Gerbing publishes no wattage, so the runtime is not derivable and we mark it that way.

Energy from capacity x voltage. With no published output current and no published draw, we cannot compute a runtime and will not estimate one. That row says 'not derivable' because it is.
23.8 watt-hours a hand is the largest figure in heated gloves that we can source, and it is worth holding next to the jacket numbers for a moment. A heated jacket carries 38.5 watt-hours to warm a torso that is already generating heat and is wrapped in insulating fabric. These gloves carry 23.8 to warm a hand — a thin, poorly-circulated extremity, usually pointed into moving air.
That is the whole reason heated gloves feel disappointing relative to their claims. Less energy, harder job.

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.

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.

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.

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.

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.

Full-finger elements are the specification that matters
Most heated gloves place the element across the back of the hand only. It is cheaper to make, it is easier to keep durable, and it warms the blood on its way to the fingers — so it is not useless. But if your fingertips are the part that goes numb, an element that stops at the knuckles is addressing the problem at one remove.
The S7 runs its element the full length of all five fingers. That is the feature to look for in this category and the one most worth paying for, and Gerbing is one of the brands that includes it as standard rather than on a halo model.
The bulk problem
A glove with elements running to every fingertip, insulation around them and a battery at the cuff is a substantial object. You will not pick up a screw in these. You will not operate a small camera control. You will struggle with a zip.
Whether that matters depends entirely on what you are doing. Riding a motorcycle: irrelevant, and these are close to the ideal tool. Standing at a touchline: irrelevant. Working on site with fasteners: the gloves come off, your hands get cold, and the purchase was wasted — heated glove liners are the format that solves that instead.
Who should skip these
- Anyone who needs dexterity. This is the main one. A glove you take off is worth nothing.
- Anyone whose gloves already work and just need heat. Liners under your existing gloves cost far less and keep a fit you have already proved.
- Anyone expecting all-day runtime. 23.8 watt-hours a hand, with no published draw, is not a figure to plan a shift around.
- Anyone whose core is cold. If your torso is cold, your body is throttling blood flow to your hands deliberately. Warm the core first — the gloves are fighting your own physiology otherwise.
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 |
|---|---|---|---|---|---|---|
| Gerbing 7V S7 Heated Gloves | 3,400 mAh | 7 V | 23.8 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 |
| SAVIOR HEAT Heated Glove Liners | 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.
The alternatives
The women's S7 is the same electronics on a narrower last, which matters more than it sounds — a glove that fits badly heats air. Heated glove liners are the format for anyone who needs their fingers. And for pure warmth with no dexterity requirement, a heated mitten beats any glove with the same pack, because five fingers sharing one chamber lose less heat than five in separate ones.
Frequently asked
- How long do Gerbing S7 heated gloves last?
- Not derivable from published figures. Gerbing publishes the pack — 7 V, 3,400 mAh, so 23.8 watt-hours a hand — but no wattage and no output current, so there is nothing to divide by. We mark it not derivable rather than estimating it.
- How many watt-hours are the Gerbing 7V battery packs?
- 23.8 watt-hours each: 3.4 amp-hours times 7 volts. With two packs in the box that is 47.6 watt-hours for the pair, the largest published figure in heated gloves that we can source.
- Do the Gerbing S7 gloves heat the fingertips?
- Yes — the element runs the full length of all five fingers rather than stopping at the back of the hand. That is the specification worth paying for in heated gloves and many cheaper models do not have it.
- Are Gerbing heated gloves good for motorcycling?
- It is the use they suit best. Constant airflow means constant convective heat loss, which is exactly the case where sustained output and full-finger coverage earn their keep, and where the bulk costs you nothing.
- Should I buy Gerbing gloves or heated liners?
- Liners if you need to use your hands — they keep your existing glove's fit and insulation plus your dexterity. The S7 if warmth matters more than dexterity and you want the largest published pack in the category.
