Corded Blower Review

BLACK+DECKER LB700 7-Amp Leaf Blower – Specs, Pros & Cons

⚡ Overview: A Light, Budget Corded Blower, Not a Cordless

The BLACK+DECKER LB700 is a corded electric handheld blower with a 7-amp motor, rated by BLACK+DECKER at up to 180 MPH and 180 CFM. Because this site is about cordless blowers, here’s the key point up front: the LB700 has no battery, and it doesn’t include a power cord either. You plug in your own outdoor extension cord and secure it with the built-in cord retainer.

What you get in return is a very light tool, listed at 4.4 lb, with unlimited runtime and a low price. This BLACK+DECKER LB700 review covers the specs, the extension-cord rules, owner feedback, and how it compares with a corded WORX and with cordless blowers I’ve reviewed. It’s built for patios, driveways, and light leaf cleanup, not heavy debris.

Yes, if you want a cheap, light blower for a patio, driveway, deck, or small lawn and don’t mind an extension cord. It’s listed at 4.4 lb, has a 2-year warranty, and BLACK+DECKER sells it for $49. It’s a poor fit for pine needles, wet leaves, or big yards. Choose a cordless blower (see our reviews) if you don’t want a cord, or the WORX WG509 if you want to vacuum and mulch leaves too.

• Best for: homeowners with a small yard, patio, deck, or driveway who want the lightest, cheapest way to clear leaves and debris
• Standout strength: 4.4 lb with a built-in cord retainer, unlimited runtime, and a price around $49
• Biggest weakness: it’s corded with no cord included, and I found no independent force test; owners say it struggles with heavier debris
• Skip it if: you want cordless freedom, have pine needles or wet leaves, or have a large property

Score basis: raised by the low weight, the low price, the cord retainer, and consistently positive owner feedback for light jobs; lowered by the cord, the single speed, limited power on heavier debris, and the lack of independent test data. It’s an editorial judgment, not a lab score, and it isn’t based on hands-on testing.

Availability note. BLACK+DECKER’s own site lists the LB700 at $49 with a 2-year limited warranty and calls it a best seller (checked October 31, 2026). Other dealers I saw ranged from about $47 to $93, and it’s a long-running model, with Amazon showing a first-available date in 2016. Retailers disagree on airflow (180 CFM vs. 220 CFM) and weight, which I show in the table below. I couldn’t open the Amazon listing, so check it for stock, the seller, and that it’s the LB700, which ships without a power cord.

💨 Power and Airflow: What 180 MPH and 180 CFM Really Mean

CFM and MPH sell blowers, but blowing force in newtons says more about how one handles a heavy pile. BLACK+DECKER doesn’t publish a force figure for the LB700, and I found no independent test, so I can’t place it on the same newton scale as the cordless blowers I’ve reviewed. What it does publish is up to 180 MPH and 180 CFM, which is well below the 450 CFM or more listed for the cordless blowers on this site.

A 7-amp motor on a 120V supply works out to about 840 W of input at most (7 × 120). That’s a theoretical nameplate figure, not measured output. Because it’s plugged in, power won’t fade as a battery drains, which is the main performance advantage of a corded blower. That’s my inference from how corded tools work, not a test result.

What owners say about the power

Owner comments are consistent: it’s strong enough for a porch, patio, driveway, or light leaves, and weak on heavier debris. One buyer on BLACK+DECKER’s site said it cleaned their porch well but wouldn’t handle leaf work in the yard, and review summaries mention limits with pine needles. Others call it plenty powerful for its size and price. Those are individual reports, and I haven’t used this blower, so I’m passing them along. If you’re comparing options, the current Amazon listing shows what’s bundled.

🔌 Extension Cord, Cord Retainer, and What You’re Buying Into

With no battery and no included cord, the extension cord decides how far you can work, and it’s the part of the purchase to plan around. The manual calls for an outdoor-rated cord of adequate gauge, because a thin cord drops voltage and can cause overheating and weak airflow. The cord chart used in BLACK+DECKER blower manuals gives these minimum gauges for a tool in the 6 to 10 amp range, which includes this 7-amp blower:

Source: the cord chart in BLACK+DECKER blower manuals, 6 to 10 amp row. A lower gauge number means a thicker wire. Confirm against the manual that came with your unit, and when in doubt, use the thicker cord.

Using the cord retainer

Plug the extension cord into the blower, then loop the cord through the built-in retention hook so a tug pulls on the hook instead of the plug. One buyer found that the extension plug doesn’t slide through the hook area, which is by design, and another says to watch the Amazon video to see how the loop works. If the cord keeps coming loose, the manual’s alternative is a simple knot.

On cost, there’s no battery or charger to buy, but you need a cord if you don’t already have one. BLACK+DECKER sells the blower for $49, and the Amazon listing will show the current price.

⚖️ Weight, Noise, Build, and Use by Job

Weight and handling

BLACK+DECKER lists the LB700 at 4.4 lb, which is lighter than the bare cordless blowers I’ve reviewed, such as the Milwaukee M18 FUEL at 4.9 lb and the DEWALT DCBL722B at 5.43 lb, before any battery is added. The grip is a comfort-style handle designed for one-handed use. Owners repeatedly praise the weight, including buyers who say they need a light tool because of age or strength. The cord adds some drag, which is the trade-off for the low weight.

Noise

I found no decibel rating for the LB700. The manual warns against pointing the inlet or outlet near your eyes or ears and says to keep bystanders and pets at least 50 ft away. A blower this small is probably quieter than a large gas model, but that’s a guess, not a measurement. Hearing protection is sensible, and local noise rules vary, so check your ordinance.

Build and durability

The LB700 is double insulated, with a plastic housing and a detachable blow tube you release with a button. I found no published weather rating, so keep it out of rain. I couldn’t find long-term durability data, but it’s a long-running model, and that’s a mildly good sign. The 2-year warranty is a reasonable backstop.

Common problems from the manual

A manual summary I read lists a few fixes. These are general guidance, so follow the manual that came with your unit.

What the numbers suggest, by job

These are reasoned from the specs and owner comments, not from my own testing.

• Patio, deck, and porch: a good fit. It’s light, and BLACK+DECKER positions it for these jobs.
• Driveway and sidewalk: a good fit for dust, grass clippings, and dry leaves.
• Small lawn with dry leaves: workable. Expect to make more passes than with a stronger blower.
• Pine needles and heavier debris: owners report it struggles here. A stronger blower fits better.
• Wet or matted leaves: expect slow going at 180 CFM. This is an inference from the rating.
• Half acre and up: the cord and the lower airflow make this a poor fit. A cordless blower is easier to move around.

⚔️ How the BLACK+DECKER LB700 Compares

Against another corded option

The WORX WG509 Trivac is a heavier corded blower that also vacuums and mulches. These are manufacturer ratings, not measurements.

Against cordless blowers on this site

The cordless blowers below have no cord but cost more once you add a battery and charger. The newton figures come from Pro Tool Reviews bench tests that I cite in those reviews; BLACK+DECKER publishes none for the LB700.

Airflow (CFM), manufacturer ratings, not measured

CFM figures come from different makers and different test methods. The LB700 is listed at 180 CFM by BLACK+DECKER and 220 CFM by some retailers. Treat this as a rough guide.

If you want the lightest, cheapest corded blower for hard surfaces and light leaves, the LB700 fits. If you want more airflow, look at the cordless blowers above or the WORX WG509. If you want to skip the cord altogether, any of the cordless options is easier to move around with.

⭐ Owner Feedback, Pros and Cons

I looked at owner reviews on BLACK+DECKER’s site and retailer pages. Tractor Supply shows 4.6 out of 5 from 67 reviews with 97% recommending, Home Depot lists 856 reviews, and mirror listings of Amazon show about 4.6 out of 5 from roughly 28,000 ratings, though I couldn’t verify that count directly. A review-analysis site estimated a lower adjusted rating of about 4.1 from a small sample. It’s an informal read of comments, so treat it as patterns I saw, not a survey. Owners praise the light weight, the low price, ease of use, and enough power for porches, patios, and light leaves. The common complaints are heavier debris like pine needles, the need to buy an extension cord, and confusion over the cord retainer. Many one-star reviews are from buyers who didn’t realize no cord is included, not from product defects.

The points below are my analysis of the specs and sources above:

🎯 Who Should Buy It

❓ BLACK+DECKER LB700 FAQ

Is the BLACK+DECKER LB700 cordless?

No. The LB700 is a corded electric blower with a 7-amp motor, and BLACK+DECKER lists it as corded with no battery. BLACK+DECKER sells separate cordless blowers, but I haven’t verified their specs.

Does the LB700 come with a power cord?

No. BLACK+DECKER lists one LB700 blower and one blow tube in the box. You need an outdoor-rated extension cord, and many one-star reviews come from buyers who didn’t expect that.

What extension cord do I need for the LB700?

Use an outdoor-rated cord of adequate gauge. The cord chart used in BLACK+DECKER blower manuals gives 18 gauge up to 25 ft, 16 gauge up to 50 ft, 14 gauge up to 100 ft, and 12 gauge up to 150 ft for a tool in the 6 to 10 amp range, which includes this 7-amp blower. Confirm against your manual.

How powerful is the BLACK+DECKER LB700?

BLACK+DECKER rates it at up to 180 MPH and 180 CFM. Some retailers list 220 CFM. BLACK+DECKER doesn’t publish blowing force in newtons, and I found no independent measurement, so I can’t compare it with tested cordless blowers on that scale.

How much does the LB700 weigh?

BLACK+DECKER lists 4.4 lb for easy one-handed use. Some listings show 4.7 lb, and a spec table shows 5.4 lb, which is probably a shipping weight.

How loud is the LB700?

I found no decibel rating for the LB700. The manual warns against pointing the inlet or outlet near your eyes or ears and says to keep bystanders and pets at least 50 ft away. Hearing protection is sensible, and local noise rules vary.

Does the LB700 have variable speed?

I found no speed dial or variable trigger. The manual’s component list shows an on/off switch, a blower tube release button, a cord retention hook, and a handle, so I’d treat it as a single-speed blower.

How do I stop the extension cord from unplugging?

Plug the extension cord into the blower, then loop it through the built-in cord retention hook, as the manual describes. One buyer found that an extension plug doesn’t pass through the hook area, and that’s by design.

Can the LB700 handle pine needles, wet leaves, or a big yard?

Owners say it’s great for patios, driveways, and light leaves, but several report it struggles with heavier debris such as pine needles and isn’t a fit for big yards. BLACK+DECKER doesn’t rate it for wet leaves. A stronger blower suits those jobs.

What warranty does the LB700 have?

BLACK+DECKER lists a 2-year limited warranty. Check the terms for the seller you buy from.

How does the LB700 compare with cordless blowers?

It’s lighter and cheaper because it has no battery, and it never runs out of charge, but you’re tied to a cord and the airflow is lower. BLACK+DECKER lists 180 CFM, against 450 CFM for the Milwaukee M18 FUEL and DEWALT DCBL722B and 530 CFM in turbo for the EGO LB5302.

🏆 Final Verdict: Is the BLACK+DECKER LB700 Worth It?

The BLACK+DECKER LB700 is a sensible budget blower for light jobs. It’s listed at 4.4 lb, runs as long as you have power, and owners consistently like it for porches, patios, and driveways. What holds it back is the cord (not included), the modest 180 CFM rating, owner reports of trouble with heavier debris, and the lack of independent force or noise data.

If your yard is small and you already own a decent extension cord, it fits well. If you have pine needles, wet leaves, or a big property, or you want to work without a cord, a stronger or cordless blower will serve you better. If it fits how you work, you can check the latest price, what’s included, and what other buyers say on Amazon.
