Electric vs Gas Snow Blower: Which One Fits Your Driveway?

Electric snow blowers clear light-to-moderate snow from paved driveways for pennies per storm, with no engine to winterize. Gas two-stage machines still own deep, wet, compacted snow and long or gravel drives. If you go corded, know that an 1,800 W blower draws about 15 A, which means a 20 A circuit and a heavy outdoor-rated cord.

Here's how to match a machine to your snow, what each one costs to run, and the electrical details most buying guides leave out.

Single-stage or two-stage: what's the difference?

The number of stages matters more than the fuel.

Single-stage. One auger scoops the snow up and throws it out the chute. The auger touches the pavement, which helps it scrape clean, but it also means single-stage machines are for paved surfaces. On gravel they pick up and throw stones. Most electric snow blowers, corded and battery, are single-stage.

Two-stage. The auger feeds the snow to a separate high-speed impeller that throws it. The auger rides above the ground on skid shoes, so two-stage machines work on gravel and handle deeper, heavier snow. They're usually self-propelled. Gas dominates this class, though battery two-stage models exist.

Three-stage gas machines add an accelerator in front of the impeller for very heavy snow. It's a niche for big properties.

Every machine lists a clearing width and an intake height. Single-stage electric models are generally on the narrow side, and two-stage machines are wider. The intake height is the most useful number on the spec sheet: it's the deepest snow the machine is designed to take in one pass. Compare it with the snowfall you usually get, not the worst storm on record.

Corded or battery: which electric is right?

The cord is the corded machine's main drawback. You have to keep it out of the auger, and it gets stiff in the cold. In exchange, it never runs out halfway down the driveway.

What circuit does a corded snow blower need?

Our appliance wattage reference lists a corded snow blower at 1,800 W. At 120 V:

1,800 W ÷ 120 V = 15 A (1,800 watts to amps, how many amps a snow blower uses).

That's the full rating of a 15 A circuit, and the NEC sets a stricter limit than that. NEC 210.23(A)(1) caps any single cord-and-plug appliance that isn't fastened in place at 80% of the branch-circuit rating: 12 A on a 15 A circuit, 16 A on a 20 A circuit. A 15 A blower belongs on a 20 A circuit, with nothing else heavy running on it at the same time.

What to check:

• GFCI protection. Outdoor and garage receptacles require GFCI protection under NEC 210.8. Snow and meltwater are the reason. See GFCI outlet requirements by room.
• A 20 A circuit. Newer homes often have a 20 A garage circuit. Older homes may not, and the outdoor receptacle might share a 15 A circuit with other loads. The home electrical load calculator and 20 amp wire size pages explain the circuit side.
• Nuisance trips. If the GFCI trips as soon as you start, look for water in the cord connection before you blame the blower. See why does my GFCI keep tripping.

What extension cord does a corded snow blower need?

Start with the cord table in your owner's manual. It's written for that motor and it takes priority.

If the manual doesn't give one, the gauge chart in our extension cord safety guide puts a 15 A load at:

The 16 AWG and 14 AWG cords sold for lights and small tools are too light for this. Undersized cords drop voltage, run hot and make the motor work harder. See wire gauge explained.

Two winter details:

• Outdoor rating. The jacket should be marked for outdoor use (the "W" in jacket types like SJTW), and ideally rated to stay flexible in the cold. Ordinary vinyl stiffens and cracks in freezing weather.
• Keep the connection dry. Keep the plug-to-cord joint up off the snow, or use a cord lock or a weatherproof connector cover. Unroll the cord fully, since a coiled cord under load traps heat.

How do batteries behave in the cold?

Lithium-ion chemistry slows down in the cold, so a cold pack delivers less of its rated capacity, and you'll see that as shorter runtime. The energy isn't gone. It comes back as the pack warms up.

What tool makers generally recommend, and your manual will confirm:

• Store and charge packs indoors, above freezing, not in an unheated garage or shed.
• Bring the pack out just before you start so it begins the job warm.
• Don't try to charge a frozen pack. Charging lithium-ion below freezing can damage it, which is why many chargers simply refuse to start until the pack is in their temperature range.
• Plan on less runtime than the box says on the coldest days, and keep a second pack charged for big storms.

The same physics is behind EV range loss in winter. See EV charging in cold weather if you want the longer explanation.

How much does each type cost to run?

Every input is stated, so you can redo this with your own numbers. Electricity is WattSimple's US average residential rate, $0.1648/kWh. Charger efficiency is assumed at 85%.

Corded, 1,800 W for 30 minutes: 1.8 kW × 0.5 h = 0.9 kWh × $0.1648 ≈ 15 cents. Real draw goes up and down with the snow load. See cost to run an electric snow blower.

Battery two-stage, two 56 V 5 Ah packs drained: 2 × (56 V × 5 Ah) = 560 Wh ÷ 0.85 ≈ 0.66 kWh × $0.1648 ≈ 11 cents.

Gas: Gallons burned per session × your price per gallon. There's no honest "typical" figure, because fuel use depends on the engine, the snow and the size of the driveway. The fill-up method works: top the tank off after clearing and note how much it took. As an example only, 0.5 gal at $3.50/gal = $1.75 per session.

For a season of 15 clearing sessions (an assumption; your winters will differ):

Energy cost doesn't decide this purchase. What separates them is upkeep: gas machines need oil, a spark plug, fuel stabilizer or a drained tank for the off-season, and they're prone to carburetor trouble from fuel that sat all summer. Electric machines need a battery that eventually wears out, or a cord that's in good condition.

What about an electric snow shovel?

An electric snow shovel is a small single auger on a handle, corded or battery. It's made for light snow on steps, decks, walks and short paths: places a full blower is too big for, or where you'd otherwise be shoveling by hand. It isn't meant for a driveway after a real storm or for the plow ridge. If most of your snowfalls are light and you have a lot of steps and walkways, it can be the only machine you need. Otherwise it's a good companion to a larger blower.

Which one should you buy?

• Short paved driveway, light to moderate snow, outlet nearby: corded single-stage, on a 20 A GFCI circuit with a properly sized cord.
• Medium paved driveway, no convenient outlet: battery single-stage, or battery two-stage if you get heavier storms. Buy a second pack.
• Long, gravel or plowed-in driveway, deep or wet snow: gas two-stage.
• Steps, decks and walkways only: electric snow shovel.

The bottom line

Choose the stage for your snow and the fuel for your driveway. Electric single-stage machines clear typical storms on paved surfaces for cents per session, with no engine to winterize. Gas two-stage machines still handle the deep, wet and plowed-in snow best. A corded 1,800 W blower draws 15 A, so put it on a 20 A GFCI-protected circuit and use the cord gauge in its manual: 12 AWG up to 50 feet and 10 AWG at 100 feet if the manual is silent. Keep battery packs warm and charge them indoors.
