Westinghouse WSnow18 Review: The 48V 18-Inch Battery Snow Blower, Decoded

Westinghouse is better known for generators and TVs than for snow blowers, but its 18-inch cordless model, the WSnow18 48V, has quietly built up close to 500 ratings on Amazon.com. It's a single-stage battery blower with a brushless motor, a steel auger and two 24V batteries, sold as a kit with a charger or as a bare tool.

If it looks familiar, there's a reason. Its specs, and much of its manual, closely match Snow Joe's 24V-X2-SB18, the most-rated battery blower on Amazon. So this review answers two questions: what can its two small 24V batteries actually clear, and is there any reason to choose it over the Snow Joe? We read the WSnow18 operator's manual, Westinghouse's product pages and the Amazon.com listings, and recorded the ratings on November 3, 2026. As with every guide on this site, we didn't test the blower ourselves. Here's how we research. For the bigger battery-versus-gas question, see are battery snow blowers worth it?

The WSnow kits, decoded

Westinghouse sells two sizes of cordless blower, each as a kit or as a bare tool. On Amazon.com they appear as options on one product page, but each option has its own ratings. Here's what each one contains, from Westinghouse's product pages and the listings:

Battery energy is our arithmetic: 24 volts × amp-hours × two packs. The manual notes that each pack peaks at 24V with no load and runs at about 21.6V under typical load, so the usable figure is around 10% lower. We use the 24V figure throughout, as we do in our Snow Joe review and our calculator, so the numbers compare directly.

The WSnow22 is a genuinely bigger machine: a wider, taller intake, a stronger motor and twice the battery energy. We mention it here because it's the obvious step up if the WSnow18's battery turns out to be too small for your driveway. The rest of this review is about the 18-inch model.

Specs from the manual

Here's the WSnow18 48V as described in its operator's manual. Where Westinghouse's listings give a different figure, we note it.

Two things are worth knowing about these numbers. First, the manual's Technical Data gives a 20-foot throw, while the Amazon.com listing and Westinghouse's store both say 25 feet. Even the Amazon spec table on the same listing says 20. We go by the manual. Second, the 39 lb net weight is about 10 lb more than Snow Joe lists for its near-identical blower. The manual doesn't say whether that figure includes the batteries, so treat it as an upper bound. Either way, it's still far lighter than a 21-inch EGO at 53 lb before its batteries go in.

What it does well

Brushless motor and a steel auger

The 1,200 W brushless motor drives four rubber-tipped steel auger blades at up to 2,500 rpm. Brushless motors waste less energy as heat than brushed ones, which matters when the battery is small. The rubber tips and the scraper bar let the auger clear close to the pavement without scarring decks or concrete, which Westinghouse highlights in its listing for walkways, porches and decks.

Simple controls and a 180° chute

A crank at the handle turns the chute through 180 degrees, so you can change the throw direction at the end of each pass without stopping. A knob on the chute sets the deflector angle, which controls how high and far the snow goes. Starting takes two steps, a safety lock button and then the trigger, so it can't start by accident, and letting go of the trigger stops the motor. The LED light helps on dark winter mornings.

Fast charging

The dual-port charger in the kit charges both 4Ah packs at once in up to 1 hour 50 minutes, the same as Snow Joe's SB18. That makes a second round after a break realistic, which is how you get the most out of a small battery in a big storm: clear early, recharge, clear again.

A tool-only option

The WSnow18T is the same blower without batteries or a charger. If you already own Westinghouse 24V batteries from its other tools, you can buy just the blower. Westinghouse's 24V System includes snow shovels such as the WSnow11S and WSnow13S in 24V versions, which use the same packs.

No engine to maintain

The manual says the motor and auger are lubricated for life at the factory and warns that adding lubricant can damage the unit. There's no oil, gas, spark plug or carburetor. Westinghouse also says each blower is functionally tested at the factory and backs it with a 2-year limited warranty and lifetime technical support. Our battery vs gas upkeep comparison covers what you stop doing when you switch.

Where it falls short

• Small battery. Two 4Ah packs hold about 192 Wh, less than half the 448 Wh in EGO's smallest 21-inch kit. It's the biggest single limit on what one charge clears.
• Both batteries, always. One dead or missing pack means no blower, and the two must have the same capacity.
• Confusing battery claims. The Amazon listing, the store and the manual don't say the same thing about which batteries fit. See below.
• Strict cold-weather rules. The manual's battery storage and charging rules are stricter than most, and in places contradict each other. See below.
• Single stage, 10-inch intake. Deep, wet snow and dense plow piles are hard on any single-stage blower, and harder on a small battery.
• Gravel needs care. There are no skid shoes; you raise the scraper by pressing down on the handle.

What one charge really clears

Westinghouse gives two numbers: up to 650 lb of snow per minute, and a working time of 15 minutes for 7 inches of snow per charge. Put together:

That's a much more modest claim than Snow Joe's 10 to 14 tons for its near-identical blower, and probably a more honest one. One odd detail: Westinghouse gives the same 15-minute figure for the WSnow22, which has twice the battery energy and a stronger motor. So the 15 minutes reads more like a rough guide than a measured result.

Tons and minutes are hard to picture, so we turned them into driveway. Fresh snow often weighs about 5 to 20 lb per cubic foot, from dry powder to wet slush. At a middling 10 lb per cubic foot, 7 inches of snow weighs about 5.8 lb per square foot, so 4.9 tons would be roughly 1,700 square feet. That assumes the blower moves snow at its top rate for the full 15 minutes, which it won't in real conditions.

A more conservative approach is to work from battery energy, as we do for every blower on this site. EGO's coverage claims work out to about 4.5 square feet of 8-inch snow per watt-hour for its smallest kit. Applying that same best-case rate to the WSnow18, then our usual rule of thumb of about half the claim in typical snow and a third in wet snow or deep cold:

These are our estimates, not measurements, and they're deliberately cautious. Halving the snow depth roughly doubles the area, because the blower moves half as much snow per square foot.

What that means for you: a two-car driveway of about 20 by 40 feet is roughly 800 square feet. In 3 or 4 inches of typical snow, one charge should about cover it. In 8 inches, expect about half the driveway per charge, so clear during the storm in two rounds or have a second pair of batteries ready. A walk 4 feet wide and 50 feet long is only 200 square feet, comfortably within one charge in most snow. To run the numbers for your own driveway, try our battery snow blower calculator, which includes the WSnow18.

Batteries: what fits and what doesn't

This is the most confusing part of the WSnow18, because its three main sources disagree:

Our reading: the manual and Westinghouse's own store are the sources to trust, and neither mentions Snow Joe packs. The two blowers are clearly related, so Snow Joe 24V packs may well fit, but the claim comes only from the Amazon listing. If you want to use Snow Joe or Sun Joe batteries you already own, ask Westinghouse support (855-944-3571) before you rely on it, so you don't risk the warranty.

What all the sources agree on:

• Always two batteries. The blower runs on two 24V packs in series and won't run on one.
• Matching pairs only. The manual says both batteries must have the same capacity. Don't pair a 4Ah with a 5Ah.
• 4Ah and 5Ah are the sensible choices. Westinghouse also lists 2Ah packs as compatible, but two of them hold only about 96 Wh, which is very little for a snow blower.
• No 8Ah or larger. The manual rules them out for the WSnow18. The WSnow22 is the blower built for the 8Ah packs.
• Don't run them flat. The manual gives a maximum depth of discharge of 80%. In practice, stop and recharge when the gauge gets low rather than running until the blower stops.

Cold weather: read the fine print

Every lithium-ion battery loses some capacity in the cold, and every battery snow blower manual has rules about it. The WSnow18 manual's rules are unusually strict, and some of them contradict each other:

• Safe range −4°F to 113°F. The general safety section gives this as the safe temperature range for the battery, and says to charge at room temperature, not outside in freezing weather.
• Charge between 32°F and 113°F, says the charging section, while the battery safety notes warn that charging below 41°F causes chemical damage to the cells.
• Store the battery at 50°F to 68°F, and the charger and tool at 50°F to 104°F.
• Packs stored below 32°F for more than 60 minutes must be discarded, according to the battery notes. That can't mean you can't use a snow blower in freezing weather. It most likely means don't leave the batteries in a cold garage or shed.

This reads like general battery boilerplate combined with snow-blower instructions, and it doesn't all fit together. Our advice is to follow the strictest reading, which is also the best routine for any battery blower:

• Keep the batteries indoors at room temperature, never in the garage overnight.
• Insert them just before you start, and take them out and bring them back inside as soon as you finish.
• Charge only warm packs. The charger shows a green light on its base if a pack is too hot or too cold, and waits until it's back in range.
• Expect less in deep cold. A warm pack delivers more energy than a cold one, and the loss comes back once it warms up.

The blower itself can freeze up. The manual says to run it for a few minutes after you finish so the auger and impeller don't freeze, wipe off ice and snow, and turn the chute crank several times to clear it. If parts freeze while you're working, stop, remove the batteries and free them before restarting. Our guide to batteries in cold weather covers storage, charging and a storm-day routine.

Wet snow and the plow ridge

These are the two jobs where a small single-stage battery blower struggles most.

Wet, heavy snow

Wet snow can weigh two or three times as much as fresh powder at the same depth. The auger has to lift and throw all of it, so the motor works harder, the batteries drain faster and the throw gets shorter. What helps:

• Let the blower set the pace. Push steadily at the rate it throws snow instead of forcing it forward.
• Take narrower cuts. Half-width passes keep the motor at a comfortable load.
• Clear during the storm, in two or three rounds, so you never face 8 inches of slush on one charge.
• Throw downwind so the snow isn't blown back at you or onto the cleared path.
• Clear a clog safely. Stop the motor, wait for everything to stop, and use the clean-out tool that comes with the blower. Never your hand: the manual says hand contact with the rotating impeller is the most common cause of snow blower injuries.

The end-of-driveway plow ridge

The ridge the street plow leaves is dense, chunky and often icy. With a 10-inch intake and about 192 Wh of battery, the WSnow18 can nibble at it from the side, but it's the wrong tool for a waist-high wall of plowed slush. Break it up with a shovel first and let the blower clear what's left. If a heavy plow ridge is a regular problem, look at a two-stage blower. Our battery snow blower guide covers this in more detail.

Gravel and uneven surfaces

The manual says plainly that the WSnow18 is intended for paved surfaces, and not to use it on gravel, stone or other unpaved surfaces unless it's adjusted for them. Single-stage blowers clear close to the ground because the auger sweeps the surface, which is what makes them good on pavement and risky on gravel, where they can pick up stones and throw them.

Like the Snow Joe, the WSnow18 has no adjustable skid shoes. The manual's method for pebbles, gravel or unpaved ground is to push down on the handle to raise the scraper above the stones. That works for crossing a gravel patch, but it's tiring over a whole driveway and hard to hold at an even height.

On a gravel drive, clear only when there's a solid layer of snow, leave an inch or so behind, and pick up stones, toys and anything else first: the auger can throw rocks, glass, nails or wire. If your drive is mostly gravel, a two-stage blower that rides on skid shoes with the auger lifted is the better choice. Our guide to wet snow, gravel and ice has more.

What owners' ratings say

Unlike Snow Joe's listings, each Westinghouse option on Amazon.com has its own ratings. Here's how they broke down on November 3, 2026:

The tool-only WSnow18T and WSnow22T had only four ratings each, too few to mean anything. The WSnow18 kit's 73% four- and five-star share is almost identical to the Snow Joe SB18's 72%, which is what you'd expect from two blowers this similar. The one-star share, about 11%, is slightly lower.

As with every small battery blower, a share of the low ratings is likely to come from expectations: owners who wanted gas-like performance in deep, wet snow, or who ran out of battery on a big driveway. On November 3 the listing ranked number 56 in Amazon.com's snow blower category, below the Snow Joe SB18 at number 25.

Westinghouse WSnow18 vs Snow Joe 24V-X2-SB18

These two blowers are so close that they're best thought of as one design sold under two brands. Neither company says so, but their manuals share large blocks of identical wording, the same specifications and the same parts list. Here's where they differ:

In practice, the choice comes down to three things:

• Which batteries you already own. If you have Snow Joe or Sun Joe 24V tools, the Snow Joe is the safe pick: its battery family is far bigger and its compatibility is clearly documented. If you have Westinghouse 24V tools, the WSnow18T lets you buy just the blower.
• Price on the day. With the same motor, path and battery, there's no reason to pay noticeably more for either one. Check both.
• Extras. Snow Joe's TV1 bundle adds a cover and a longer warranty; Westinghouse offers lifetime technical support.

Our Snow Joe 24V-X2-SB18 review covers its kits in detail. Both blowers share the same core limit: about 192 Wh of battery in the standard kit.

Which one to buy

For small jobs, a powered shovel is the other option. It's lighter and cheaper, and enough for steps, decks and short walks. See our best cordless snow shovels guide, and snow shovel vs snow blower if you're deciding between the two.

Upkeep and storage

After every use

• Run the blower for a few minutes so the auger and impeller don't freeze, then turn it off and wait for everything to stop.
• Wipe off ice and snow and turn the chute crank several times to clear the chute.
• Remove the batteries and bring them inside.
• Now and then, check for loose bolts, damaged parts and anything binding.

Parts and support

The motor and auger are lubricated for life, so there's no greasing; the manual warns that lubricating them can damage the unit. For replacement parts or accessories, the manual says to contact Westinghouse Outdoor Power Equipment at 855-944-3571. Have the model and serial numbers ready; they're on the decal on the blower. Replace the scraper bar when it starts leaving a layer of snow behind.

Off-season

Clean the blower, remove the batteries and store everything indoors in a dry place. Keep the batteries and charger at room temperature, away from moisture, and never anywhere above 104°F to 120°F, such as a hot car or shed, which causes permanent capacity loss. See our off-season battery storage guide.

Warranty

Westinghouse lists a 2-year limited warranty and lifetime technical support through its nationwide service network. The manual asks you to register the blower at wpowereq.com/pages/warranty-registration, or by mail, for trouble-free warranty coverage, and to note the model and serial numbers and the date and place of purchase. Keep your receipt.

Verdict

The Westinghouse WSnow18 48V is a capable small battery snow blower. For walks, decks, patios and small paved driveways in light-to-moderate snow, it does the job, with a brushless motor, a steel auger, a 180° chute and a fast dual-port charger. Its 4.0-star average from nearly 500 ratings matches the Snow Joe SB18 it so closely resembles.

Its limit is the same as the Snow Joe's: about 192 Wh of battery. In 8 inches of typical snow, that's roughly half a two-car driveway per charge by our estimate. Buy it for small areas, clear little and often, and budget for a second pair of batteries if your driveway is bigger. Stick to Westinghouse batteries unless support confirms otherwise, and keep them indoors. If you regularly face big driveways, deep wet snow or a heavy plow ridge, the WSnow22 or a bigger blower is a better fit.
