Best Electric Chipper Shredder: Six Models Compared by Capacity

As an Amazon Associate we earn from qualifying purchases. Details

The best electric chipper shredder for most yards is a corded 15-amp model whose branch capacity matches the wood you cut and whose cord and outlet you can set up safely. A person typing best electric chipper shredder wants a machine that turns branches into mulch without a gas engine, and wants to know what the cord, the outlet and the safety features require. This guide compares six electric chipper shredders from six brands by the branch size, bin or bag and weight each listing gives. Every listing here states a 15-amp motor, so the cord and outlet matter as much as the machine.

Quick answer

• Widest stated branch size with a bag: the LawnMaster FD1503 and the Earthwise GS70015 both give a top cutting figure of 1.8 inches.
• Lightest machine: the WEN 41119 gives the lowest weight in this set, 20.1 pounds, and includes a startup interlock.
• Largest bin: the MAXLANDER listing names a removable 45 liter bin, which our planning estimate puts at about 11.9 gallons, a little more than the Earthwise bag.
• Before you plug it in: a 15-amp tool needs a heavy enough extension cord and a GFCI-protected outlet, as the LSU AgCenter and Earthwise bullets describe.

Chipper or shredder: what the listings mean

A chipper takes branches up to a stated diameter and turns them into chips. A shredder breaks down leaves and softer green waste. The six listings in this guide are chipper shredders, which means they are meant for woody branches as well as leaves and twigs. The labels blur in places. The Sun Joe CJ603E has “Wood Chipper Shredder” in its title, and one of its bullets calls the same machine a “leaf mulcher.” The WORX leaf mulcher that appeared in the same search is a different kind of machine for leaves, so this guide does not include it.

Ohio State’s chipper page describes these machines as using “sharp cutter knives,” and it warns that those knives “are more than capable of cutting flesh and bone if a worker accidentally gets pulled into the machine.” That is the main reason the safety section below matters more than the mulch claims in the bullets.

Branch capacity: what the numbers say

Table 1 sets out the branch or cutting figure, the motor, the bin or bag and the weight each listing gives. A dash means the listing or its specification table did not give that item in the text we extracted.

Listing	Branch or cutting figure	Motor (per bullets or title)	Bin or bag (per bullets or title)	Weight (per specifications)
LawnMaster FD1503	Up to 1.8 inches	15-amp	Bag, named in the title	23.2 pounds
Earthwise GS70015	Up to 1.5 to 1.8 inches	15-amp	10.5 gallon bag	29.8 pounds
Sun Joe CJ603E	Up to 1.7 inches	15-amp	Collection bag, named in the title	Not given
WEN 41119	Up to 1.75 inches	15-amp	Collection bag, named in the bullets	20.1 pounds
MAXLANDER 15-amp	0.9 to 1.8 inches (bullets); 1.75 inches (title)	15-amp, up to 4000 RPM	Removable 45 liter bin	23.9 pounds
PowerSmart PS10A	1-3/4 inches (45 mm); 1.77 inches (specifications)	120V, 15A	Collection bag, named in the title	22.7 pounds

The weight range is the clearest spread in the set. The heaviest listing with a stated weight is 9.7 pounds heavier than the lightest, because 29.8 minus 20.1 is 9.7. Three listings state a top figure of 1.8 inches, and each of them weighs more than 23 pounds where a weight is given, so the larger capacity in this set comes with more weight to move.

The MAXLANDER bin needs one conversion to compare with the Earthwise bag. Dividing 45 liters by 3.785 liters per gallon gives about 11.9 gallons, which is our planning estimate, against the 10.5 gallons the Earthwise listing states for its bag.

Branch size is the first number to match. If your largest branch is around an inch, all six machines cover it on paper. If you regularly cut wood near the top of the range, the 1.8 inch figures in the LawnMaster and Earthwise listings leave the least margin for error, and the listings in this set stop there. A limb larger than what the listing states is outside what that machine is sold to handle.

Cord, outlet and GFCI: the part most buyers miss

All six listings state a 15-amp motor. The LSU AgCenter guide says that “longer cords must be heavier to reduce voltage drop and prevent overheating.” Its advice is to size the wire by the tool’s amp rating and the length of the run. The Earthwise bullets put that into numbers: “For 15-amp operation, use a 12-gauge (12 AWG) extension cord up to 75 ft or 10-gauge for longer distances to prevent voltage drop, overheating, and loss of power.” That line comes from the listing, and the extension cord is not included.

The same LSU guide advises that “If you are using outdoor electric tools, you should plug them into a GFCI-protected outlet.” A GFCI outlet cuts power quickly when it detects a current imbalance. The University of California Irvine electrical guide describes it as “a fast-acting circuit breaker designed to shut off electric power at a speed of 1/40th of a second when it detects a difference in outgoing and incoming current.” If your garden outlet is not protected, the LSU guide lists ways to add protection, including GFCI outlets and a GFCI breaker.

For the cord itself, the University of Texas at Austin safety factsheet says that “Extension cords must be 3-wire type so they may be grounded,” and that you should “Do not use an indoor extension cord for outside use.” The UC Irvine guide also says that “Extension cords are TEMPORARY USE ONLY,” so a long cord that stays on the lawn for months is the wrong setup. Plan the outlet first, then choose a cord that matches the machine’s rating.

A quick planning figure helps show why the cord matters. On a 120-volt circuit, 120 times 15 is 1,800 watts, which is our planning estimate of a 15-amp tool at full load. The PowerSmart listing gives 120V, and the other listings do not state a voltage. That number is a rough guide, not a rating from any listing.

Safety while the machine runs

The Ohio State chipper page lists several checks that apply to any chipper shredder. It advises you to “Test all safety and emergency shut-off devices for proper operation.” It also says to “Make sure the material to be chipped is free from stones, metal and foreign objects.” Those two points are simple, and they protect the knives and the operator. Check each pile for stones and metal before it goes into the feed.

The page also advises ear protection. It says to “Wear ear protection to preserve hearing and protect ears from the high level of noise produced by the engine and cutting knives.” The Ohio State page is written for machines with engines. A corded model is usually quieter than an engine-driven one, but the sources we opened do not compare noise levels across electric models. The Sun Joe specifications give a noise figure of 94 dB, which is the only noise number in this set, and the listing does not put it in context.

Several listings describe interlocks or shut-offs. The WEN bullets say an “Internal safety mechanism automatically prevents startups when the hopper is still open.” The Sun Joe bullets say an “integrated safety hopper and locking knob halts operation immediately when opened.” The Earthwise bullets describe “overload protection and a safety interlock switch located between the cover and main body.” The MAXLANDER bullets describe a “Built-in safety shut-off” linked to its collection container. These are listing claims. The sources we opened do not test any of these devices, so check the device on the machine you buy before you rely on it.

Hands and clothing need the same care as the knives. The Ohio State page recommends wearing “pants and a snug-fitting, long-sleeved shirt to protect the skin from flying debris and to avoid being caught or pulled into the machine.” Keep loose sleeves and long hair away from the feed.

What to feed it and what it makes

The Earthwise bullets address moisture directly. They say the chipper is “Designed for best performance with dry, seasoned branches and yard debris, producing fine mulch for composting,” and they add that “Green or freshly cut material may reduce efficiency due to higher moisture content.” That is the only moisture guidance in the set, and it matters for anyone who prunes in spring.

The LawnMaster bullets make a different claim: that you can “Reduce 14 bags of bulky yard debris into 1 bag of nutrient-rich mulch.” That is a listing claim about volume. It does not say what mix of branches and leaves produced it, and the sources we opened do not cover that ratio. Treat it as a marketing figure, and plan for your own debris.

The MAXLANDER bullets describe a 21:1 mulching ratio. That is also a listing claim. If you want to estimate your own volume reduction, measure your debris before and after a few runs. A short test on one pile of dry branches tells you more about your own yard than any ratio on a listing.

Choosing for your yard

1. Start with your largest branch. If it is near 1.8 inches, the LawnMaster and Earthwise listings state that figure, and the others state less.
2. Plan the outlet and cord before you buy. A 15-amp machine needs a GFCI-protected outlet and a heavy enough cord for the run, as the LSU and Earthwise guidance describes. A longer run needs heavier wire.
3. Decide between a bag and a bin. The Earthwise and LawnMaster listings name bags, while the MAXLANDER listing names a removable 45 liter bin. A bin is easier to empty when you have a large pile, but it is also heavier to lift when full.
4. Weigh the machine. The WEN is the lightest listing that gives a weight, at 20.1 pounds. The Earthwise is the heaviest at 29.8 pounds, and the Sun Joe weight is not stated.
5. Look for the safety features you want. The WEN, Sun Joe, Earthwise and MAXLANDER listings each describe a shut-off, interlock or locking feature in their bullets. Test the feature on the machine before you feed it.

How we chose

We searched Amazon.com in Chrome for best electric chipper shredder on 21 October 2026 and read the first results page. We kept corded electric wood chippers and chipper shredders for branches, and we dropped a leaf mulcher and any accessory or replacement part. We opened six listings from six brands. The other corded chippers on that page were not opened, so this set does not cover the whole market.

For each listing we read the title, the first four feature bullets, the next four where the listing had them, and the specification table. We did not use prices, ratings, sales rank or stock status, because the extraction did not return them reliably and they do not help a buyer choose a chipper. The six picks below are the six listings we opened, and their order does not rank them.

What we could not verify

• Whether any of these machines chips its stated diameter in real wood. The branch figures are listing claims, and the sources we opened do not test them.
• Which brand made each machine. The LawnMaster specifications name Cleva as manufacturer, and the Earthwise specifications name American Lawn Mower Company. The brand names in the bylines are the ones we used.
• The Sun Joe weight, which the specification table we extracted does not give.
• Whether the interlocks and shut-offs work as described. The bullets name them, and the sources we opened do not cover these devices.
• The electrical claims. The PowerSmart bullets describe double insulation and IPX4 protection, and the sources we opened do not cover those ratings.
• Noise levels beyond the one Sun Joe figure of 94 dB.
• Bag and bin capacities beyond what the listings state. The 45 liter to 11.9 gallon conversion is our planning estimate, not a listing figure.
• Warranty terms beyond the WEN bullets, which mention a two-year warranty.
• Anything below the first eight bullets of each listing.

FAQ

Can an electric chipper shredder handle thick branches?

The listings in this set state cutting figures from 1.5 to 1.8 inches, and no listing here states a larger capacity. Check the figure on the machine you choose, and cut larger wood in pieces that fit it. A limb wider than the stated figure is outside what that machine is sold to handle.

Do I need a GFCI outlet for an electric chipper?

The LSU AgCenter guide advises plugging outdoor electric tools into a GFCI-protected outlet. The University of California Irvine guide describes GFCI as a fast-acting breaker that cuts power when it detects a current imbalance. If your outdoor outlet is not protected, have an electrician add a GFCI outlet or breaker before you use the machine.

What extension cord should I use?

The Earthwise listing gives 12-gauge wire for runs up to 75 feet and 10-gauge for longer runs, for a 15-amp tool. The University of Texas safety factsheet says extension cords must be 3-wire types so they can be grounded, and the UC Irvine guide says extension cords are for temporary use only. Match the cord to the machine’s rating and the length of the run.

Are electric chippers better than gas ones?

The listings say these machines run without gas or fumes. The Sun Joe bullets say the machine “powers up instantly with the push of a button without fuel or fumes,” and the Earthwise bullets say “without gas or fumes.” The sources we opened do not compare electric and gas models for power or cutting capacity, so compare the figures on each listing.

What should I feed into the chipper?

Feed dry, seasoned branches where you can. The Earthwise bullets say green or freshly cut material may reduce efficiency. The Ohio State page says to keep stones, metal and foreign objects out of the feed, and the Sun Joe listing describes branches and twigs as the main material.

Bottom line

Choose the WEN 41119 if weight and a startup interlock matter most, at 20.1 pounds. Choose the MAXLANDER if you want the largest collection bin and expect to empty it often. Choose the LawnMaster FD1503 or the Earthwise GS70015 if the stated 1.8 inch figure matters most, and plan a GFCI outlet and a heavy cord before the first run.
