Best Cordless Electric Lawn Edgers

The best cordless electric lawn edgers for most homeowners are the EGO Power+ 56V Power+ 8-inch Edger for maximum cutting control, the DEWALT 20V MAX XR 8-inch Edger for smaller yards already using that battery platform, and the Greenworks 60V 8-inch Edger for buyers who want strong performance without stepping up to a commercial-style system.

A good choice depends less on the advertised voltage than on four practical details: how deep the blade can cut, how many linear feet you need to edge, whether your existing batteries fit, and whether the guide keeps the blade at a consistent distance from concrete or paving. The comparison below focuses on those factors rather than treating every cordless edger as interchangeable.

Best cordless electric lawn edgers compared

Runtime figures are useful planning estimates, not guaranteed specifications. Hard soil, maximum depth, tall runners, frequent stops, and a dull blade can reduce them substantially. Batteries and tool versions may also change, so confirm the depth range and included accessories before buying.

Our top picks by yard and path layout

Best overall: EGO Power+ 56V 8-inch Edger

The EGO Power+ edger is the strongest all-round choice when the lawn meets a driveway, sidewalk, patio, or several separate paths. Its high-voltage battery provides a useful reserve when the blade encounters compacted soil or thick grass runners, while the adjustable blade depth lets you maintain an existing trench instead of cutting a new, shallow line every time.

Choose it when you have a medium or large property, long straight runs, or borders that have been neglected for a season. Its main disadvantage is system cost: the bare tool is often in the roughly $180–$250 range, while a battery and charger bundle can push the package into the $300–$500 range.

Best for an existing 20V battery collection: DEWALT DCED400

The DEWALT 20V MAX XR DCED400 makes sense for smaller properties and homeowners who already own compatible 20V MAX batteries. It is easier to justify financially than buying a new high-voltage ecosystem, and its 8-inch blade is sufficient for routine edging along walkways and curbs.

Its lower maximum depth is not a serious limitation if you edge every week or two. It becomes a drawback when reclaiming a border covered by turf runners or when you want a visibly deep separation between lawn and paving. Use a charged 5.0Ah or larger pack for longer continuous passes; compact batteries reduce weight but can make the tool stop for a recharge sooner.

Best value high-voltage platform: Greenworks 60V Edger

A Greenworks 60V edger is a strong option for homeowners who want high-voltage performance and intend to add a mower, trimmer, blower, or chainsaw on the same platform. The 8-inch blade and adjustable depth suit both routine maintenance and moderately overgrown borders.

It is especially attractive when the same battery will power several tools during one yard session. The trade-off is that high-voltage packs are heavier and more expensive than compact 20V batteries. Buy this type when you value power and platform versatility more than minimum carrying weight.

Best for a broad outdoor-tool ecosystem: RYOBI 40V HP Expand-It

The RYOBI 40V HP Expand-It edger is aimed at homeowners who want one outdoor battery system and may already own compatible RYOBI equipment. The Expand-It design can also be useful when storage space is limited, although attachment systems add another connection that should be cleaned and tightened regularly.

Its adjustable depth is appropriate for restoring an uneven border, but avoid cutting at maximum depth in one pass. Two shallower passes use less energy, place less stress on the blade, and produce a cleaner edge in hard soil.

How much battery capacity do you need?

Estimate the job before choosing a battery. Measure the lawn perimeter that actually needs edging, then divide that distance by your walking speed. For example, 600 linear feet at 2 feet per second takes:

600 feet ÷ 2 feet per second = 300 seconds, or 5 minutes of trigger-on cutting.

That sounds easy, but corners, repositioning, trimming around gates, and clearing clumps can double the real session to 10–12 minutes. A 2.5Ah high-voltage battery is usually enough for this job. For 1,500 linear feet with heavy growth, allow approximately 25–35 minutes of actual work and choose a 4.0Ah or 5.0Ah pack, or keep a spare charged.

Battery watt-hours provide a better comparison than amp-hours alone:

Watt-hours = nominal volts × amp-hours.

A 20V 5.0Ah battery stores about 100 watt-hours, while a 56V 2.5Ah battery stores about 140 watt-hours. The higher-voltage pack is not automatically twice as powerful, but it has more stored energy in this example and may maintain cutting performance better under load. Actual usable energy is lower because of electronic limits, temperature, and resistance.

Blade depth: match it to the border

• 1 to 1.5 inches: best for frequent maintenance where the edge is already established.
• 2 inches: a practical setting for most weekly or biweekly edging beside concrete.
• 3 inches: useful for reclaiming a soft, overgrown border, but slower and more demanding on the battery.
• 4 inches: reserve for established deep trenches and loose soil; do not force the blade into roots, buried cable, or compacted paving material.

For a new edge, start at about 1.5–2 inches and make a second pass only if the wall of soil remains intact. A very deep first cut often throws soil onto the path and makes the edger bounce, which creates a less accurate line despite the larger depth setting.

Edging guides matter more than they appear

A blade guard alone does not tell you where the cut is occurring. The most useful designs have a curb wheel, wire guide, or adjustable guide that follows the edge of the pavement. A wheel is preferable for long, smooth sidewalks because it limits sideways movement. A wire or visual guide can be better around curved garden beds, where a fixed wheel may pull the machine away from the intended line.

For a sidewalk with a 2-inch concrete lip, set the guide so the blade is about 1/4 inch away from the concrete rather than rubbing against it. Keep the tool vertical and let the guide—not your arms—control the distance. On a curved path, walk more slowly and make short steering corrections; trying to maintain speed causes the blade to cut inside the curve.

Decision matrix: which cordless edger fits your situation?

What to check before buying

• Confirm whether the listing is for a bare tool or includes the battery and charger.
• Check the replacement blade’s diameter, center-hole size, and availability.
• Look for tool-free depth adjustment; knobs that require a wrench are inconvenient during seasonal changes.
• Check whether the battery sits at the top or rear. A top-mounted pack can make the nose feel heavy on long paths.
• Verify that the guide can be adjusted for both a sidewalk edge and a garden-bed edge.
• Inspect the guard design if you regularly cut damp grass, since wet debris can clog narrow clearances.

Bottom line

Choose the EGO Power+ 56V edger for the best combination of depth control, power reserve, and long-border performance. Choose the DEWALT DCED400 when you already own DEWALT 20V batteries and maintain a smaller yard. Choose a Greenworks 60V or RYOBI 40V edger when the battery platform will also serve your mower, trimmer, blower, or other outdoor equipment. Whatever the brand, prioritize a stable edging guide and a battery sized for your total linear footage—not merely the highest voltage printed on the box.
