7V vs 12V: which Gerbing system is right for you?
Same patented heat — two ways to power it. Here's how rechargeable 7V and hardwired 12V compare, and how to pick the one that fits how you ride and live.
7V Rechargeable
Cordless heat that goes everywhere
7V gear runs on a rechargeable lithium battery that tucks into the garment — no wires, no bike required. It's the most versatile way to stay warm: wear it walking the dog, on the job site, at the game, or layered under a riding jacket. Expect roughly 2–8 hours of runtime depending on heat level, then recharge and go again.
- Fully cordless and machine washable
- Great as an everyday layer or travel piece
- Up to ~140°F on high
12V Motorcycle
Unlimited warmth for the long ride
12V gear wires directly into your motorcycle's battery through the included harness, so it draws power continuously — there's no battery to drain and no runtime limit while the engine runs. It's built for riders who spend real hours in the cold and want steady, set-and-forget heat for the whole trip.
- Hardwires to the bike — never runs out
- Highest sustained output for long exposure
- Up to ~135°F, controlled on the fly
The shared core
One heating technology, two power sources
Whichever you choose, the heat itself is identical: Gerbing's patented Microwire system weaves thousands of ultra-fine conductive filaments into the garment for even, durable warmth with no hot spots. The only real decision is how you want to power it — a rechargeable battery you carry, or your motorcycle's 12V system.
Side by side
7V vs 12V at a glance
Both deliver the same Microwire warmth. The differences are all about power, runtime, and how you'll use it.
7V vs 12V — common questions
Which is warmer, 7V or 12V?
Peak temperatures are very close (7V up to ~140°F, 12V up to ~135°F). The meaningful difference is endurance: 12V pulls continuous power from your bike so it never fades, while 7V runs on a rechargeable battery for a few hours per charge.
Can I wear 12V gear off the motorcycle?
12V gear is designed to wire into your bike. It can run off a compatible portable 12V battery pack, but if you want true cordless, everyday warmth, 7V is the better fit.
Can I use 7V gear while riding?
Yes. Plenty of riders wear 7V layers on shorter rides or as a base layer. For all-day rides in serious cold where you don't want to think about runtime, 12V is the stronger choice.
Do both use the same heating technology?
Yes — both lines use Gerbing's patented Microwire heating. The garments and heat zones are engineered the same way; only the power source differs.
Which should I buy if I'm not sure?
If most of your time is off the bike or you want one versatile piece, go 7V. If you ride long distances in the cold and want heat that never runs down, go 12V. Still stuck? Reach out and we'll help you choose.
