- You want variable speed control: the DCE100B's trigger gives you more precise blowing force.

Price — BLACK+DECKER Wins
The BLACK+DECKER LB700 is the clear value winner. It comes ready to blow leaves with a simple corded connection, while the DEWALT bare tool needs a separate battery purchase.
In daily use, the lower upfront cost means less risk. If you only need occasional leaf clearing, the corded model avoids idle battery maintenance and the sunk cost of a platform you may not yet own.
Budget‑conscious buyers should prioritize the BLACK+DECKER. It makes the most sense for anyone who owns a standard extension cord and wants performance without the DEWALT premium.
Air Flow (CFM) — BLACK+DECKER Wins
The BLACK+DECKER pushes 180 cubic feet per minute, compared to just 100 CFM from the DEWALT. That 80% advantage means a stronger, wider blast of air to clear leaves faster.
In practice, the higher CFM lets you sweep debris from driveways and patios with fewer passes. Dry leaves lift effortlessly, reducing time spent on cleanup.
If your yard has heavy leaf fall or you value swift clearing, the BLACK+DECKER is the winner. The DEWALT's 100 CFM will feel underpowered for more than light touch‑ups.
Weight — DEWALT Wins
The DEWALT DCE100B weighs just 3.7 pounds, making it one of the lightest handheld blowers available. The BLACK+DECKER comes in at 4.4 lbs — still manageable but slightly heavier.
During long sessions, even a 0.7‑lb difference reduces arm strain. If you have a large driveway or multiple patios, the DEWALT will feel more comfortable over time.
Choose the DEWALT if you plan to use the blower for extended periods. The weight advantage pairs well with its cordless design for fatigue‑free mobility.
Runtime — BLACK+DECKER Wins
With a corded design, the BLACK+DECKER runs indefinitely as long as it’s plugged in. You never worry about a dying battery mid‑job.
The DEWALT’s runtime depends entirely on the battery you attach. A small 2Ah pack may give only 10–15 minutes of hard use; larger batteries add cost and weight.
If you have a big yard and one outlet within reach, the corded blower is the dependable choice. For truly wire‑free operation, the DEWALT will need spare batteries.
Mobility — DEWALT Wins
The DEWALT’s cordless design gives you complete freedom to roam. No extension cord to drag, no worrying about outlets — you can walk around trees and fences without planning a cord route.
The BLACK+DECKER is limited to about 100 feet from the nearest outlet with a standard extension cord. For small yards that’s enough, but navigating obstacles with a cord can be frustrating.
If your property has multiple disconnected areas or lacks convenient outdoor outlets, the DEWALT wins on mobility. It’s the simpler, untethered experience.
Power Source — Tie
The BLACK+DECKER plugs into any standard 120‑volt outlet, delivering constant 7‑Amp power. No batteries to charge, no performance fade — just steady airflow.
The DEWALT runs on the 20‑V MAX battery platform, shared with hundreds of other tools. Existing DEWALT owners can swap batteries effortlessly, but newcomers must invest in both tool and battery.
Neither power source is universally better — it depends on your existing setup. If you’re already in the DEWALT ecosystem, cordless is convenient; otherwise, corded simplicity wins.
Rating — BLACK+DECKER Wins
The BLACK+DECKER LB700 holds a 4.6‑star average from over 30,000 verified Amazon reviews. That’s a massive sample of satisfied users, with many praising its power and value.
The DEWALT DCE100B scores 4.4 stars from about 15,000 reviews. Buyers appreciate its lightweight design but frequently note the low 100 CFM as a limitation for real yard work.
Higher ratings and double the review volume give the BLACK+DECKER a trust advantage. It’s a proven, popular choice for budget‑conscious lawn care.
Control & Ergonomics — DEWALT Wins
The DEWALT features a variable‑speed trigger with a lock button, letting you dial in the exact airflow for each task. For gentle cleaning around flower beds, you can use low speed; for full‑blast leaf duty, max it out.
The BLACK+DECKER has a simple on/off switch — no speed adjustments. While 180 CFM is powerful enough for most jobs, you can’t reduce the blast for delicate areas.
If you want precise control over blowing force, the DEWALT’s trigger is a meaningful advantage. It’s especially useful in tight spaces or when clearing light debris from hard surfaces.

Frequently Asked Questions
BLACK+DECKER LB700 vs DEWALT DCE100B: which is better?
It offers 180 CFM of air flow, 180 MPH airspeed, and a significantly lower price — all backed by 30,000+ positive Amazon reviews.
Is the DEWALT DCE100B worth the extra cost?
Only if you need cordless convenience and are already invested in the DEWALT 20V battery system. Even then, its 100 CFM air flow is weak for heavy leaf work.
How long does the DEWALT DCE100B battery last?
The manufacturer does not state a specific runtime; it depends entirely on the DEWALT 20V battery you attach. A small 2Ah battery may last under 15 minutes on high, while a 5Ah pack could extend that to 30–40 minutes. For big jobs, have spare high‑capacity batteries ready.
What's a more powerful corded alternative to these two?
It's heavier but ideal for large yards with heavy leaf cover.
Does the BLACK+DECKER LB700 come with a cord?
No, it has a short power cord; you'll need a heavy‑duty outdoor extension cord. A 16‑gauge, 50–100 ft cord works well. Always use a cord rated for outdoor use and ensure it can handle the 7‑Amp draw of the blower.
