Best Earthwise GS70015 15-Amp Garden Corded Electric
As an Amazon Associate we earn from qualifying purchases.
If you are looking at the best Earthwise GS70015 15-amp garden corded electric chipper, the first question is whether your debris matches what it is built for. The Amazon listing (ASIN B00W874Y46) says it chips dry, seasoned branches and sticks up to about 1.75 inches thick into fine mulch for composting, and that it is not intended for leaves or fibrous plants. It is a corded machine, and the listing does not include the extension cord. This post covers that one model, using the listing and two Ohio State University Extension pages on wood chippers and shredders in general.
Quick answer
- Fit: the listing says the chipper handles yard waste, debris and sticks up to 1.75 inches thick, and that it produces fine mulch for composting from dry material.
- Power: a corded 15-amp electric motor on a 120-volt product. The extension cord is not included, and the listing says to use a 12-gauge cord up to 75 feet.
- Limits: the listing says it is not intended for leaves or fibrous plants such as corn stalks, and that green material may reduce efficiency.
- Skip it if your debris is mostly green or leafy, or if you need a battery-powered machine rather than a corded one.
The product at a glance
The table lists what the Amazon listing states. Where the listing is silent, the cell says “not stated”. Each row is either a figure from the listing or a gap in it.
| Item | What the listing states |
|---|---|
| Brand | Earthwise |
| Manufacturer | American Lawn Mower Company (listing) |
| Model | GS70015 |
| ASIN | B00W874Y46 |
| Power source | Corded electric, 15-amp motor |
| Motor speed | Up to 4500 RPM (product description) |
| Voltage | 120 volts (product voltage) |
| Extension cord | Not included. 12-gauge up to 75 ft, or 10-gauge for longer distances (listing guidance) |
| Cutting capacity | Up to 1.5 to 1.8 inches (one bullet); up to 1.75 inches (product description) |
| Mulch ratio | Styles of 12:1 and 8:1; a bullet says it reduces yard waste by up to 15:1 |
| Blades | Heat-treated SK5 steel, with anti-rust oil applied before release |
| Collection | 10.5-gallon capacity (the listing uses both “bag” and “bin”) |
| Overload protection | Yes; safety shutoff with a re-set button by the power button |
| Safety interlock | Switch between the cover and the main body |
| Dimensions | 42 x 24 x 18 inches |
| Weight | 29.8 pounds |
| Battery | Not applicable; the listing describes a corded model |
| Warranty | Listing links to a warranty PDF; terms not in the text opened |
| Intended material | Dry, seasoned branches and yard debris; not leaves or fibrous plants |
Two of the listing’s figures do not match, and the post shows both. The style names give 12:1 and 8:1 mulch ratios, while one bullet says the chipper reduces yard waste by up to 15:1. The listing does not explain how the bullet figure relates to the styles, so the table reports all three as stated. The capacity figures also differ slightly: one bullet gives 1.5 to 1.8 inches, and the product description gives 1.75 inches.
Some arithmetic follows from the listing’s own numbers. Power input at the rated current is 120 V x 15 A = 1,800 W. That is a nominal figure from the listed voltage and amperage. The listing states no output power, so this post does not compare it with any gas machine. The collection capacity is 10.5 gallons x 0.1337 cubic feet per gallon = about 1.40 cubic feet. The listed weight is 29.8 pounds x 0.4536 = about 13.5 kg.
The rows that matter most for a buyer are the cutting capacity, the cord, and the intended material. The capacity sets the largest stick the chipper is stated to take. The cord row decides whether the machine can reach your debris, because the listing does not supply one. The intended-material row decides whether the machine suits your waste at all.
Who it suits
This chipper fits a homeowner who has dry, seasoned branches and sticks up to about 1.75 inches thick, a 120-volt outlet that a 12-gauge extension cord can reach, and a use for fine mulch in compost or beds. The listing describes exactly that use: dry branches, yard debris, and mulch for composting. The listed collection capacity is 10.5 gallons, or about 1.40 cubic feet by the conversion above. A buyer who produces more mulch in a session will empty the bin more than once, and the listing does not say how quickly it fills.
The listing says a lightweight design and transport wheels make the chipper easy to move around a yard. The listed weight is 29.8 pounds and the listed footprint is 42 by 24 inches. A buyer who moves the machine between piles will find the wheels and weight the listing describes. A buyer who wants to carry it up steps should weigh that figure against their own strength and the terrain. The listing gives no lifting guidance, so the 29.8-pound figure is the only weight the post can state.
The safety points that apply to any wood chipper come from Ohio State University Extension, not from the listing. The factsheet advises keeping hands and feet away from the discharge chute and moving parts, and wearing eye and hand protection. Those points apply to this model whether or not the listing repeats them. The listing’s own shutoff and interlock features cover different risks from the hand and foot rule.
Skip it if
- Most of your debris is green or freshly cut, or it is leaves. The listing says green material may reduce efficiency and that the machine is not intended for leaves or fibrous plants.
- Your branches are thicker than about 1.75 inches. The listing gives 1.75 inches in one place and 1.5 to 1.8 inches in another, and it does not state a larger figure.
- You cannot run a 12-gauge extension cord from a 120-volt outlet to where the debris sits. The listing says the cord is not included, and it gives 75 feet as the longest 12-gauge run.
- You want a battery-powered or cordless chipper. The listing describes a corded electric model and no battery. If you are comparing corded and battery yard tools, read our pros and cons of electric mowers guide next.
- You need a warranty term before ordering. The listing links to a warranty PDF, and its terms were not in the text this post opened.
What the listing does not say
The listing is clear on the motor, voltage, blades and collection capacity. It leaves several points open that a buyer should check.
- Cord. The listing says the extension cord is not included and gives gauge and length guidance. It does not give a plug type or a cord length that comes with the machine, and it does not say how the machine connects to the outlet. For a longer look at cords on electric yard tools, see our extension cord guide for electric lawn mowers.
- Output power. The listing gives the voltage and the 15-amp motor. It does not give an output power figure, so the 1,800 W figure above is an input calculation only.
- Mulch ratio. The 15:1 bullet and the 12:1 and 8:1 style names are not reconciled in the listing.
- Feed opening. The listing gives no size for the hopper or feed opening, so the post cannot say what diameter fits the opening as opposed to the stated maximum.
- Green material. The listing says efficiency may drop with green material, but it gives no figure for how much.
- Dimensions in use. The 42 x 24 x 18 inches figure is the listed product size. The listing does not give a storage or operating clearance around the machine.
- Parts. The text captured does not say whether replacement blades or parts are sold for this model.
How we chose
This post covers one product: the Earthwise GS70015 15-Amp Garden Corded Electric Chipper, ASIN B00W874Y46, listed under wood chippers, shredders and mulchers. It is in this batch because the keyword names it directly. The criteria were the stated capacity, motor, voltage, cord guidance, collection capacity, intended material, stated limits, dimensions and weight. The product data comes from the Amazon listing, read on 2026-10-22 (the CHECKED date in the listing file).
The two Ohio State University Extension factsheets are the non-retail sources. They cover wood chippers and shredders in general, including gasoline-engine and tractor-powered units, and they do not cover this corded electric model. The post uses them only for points that apply to any chipper. The listing’s intended-material line and its stated limits were read in full before any criterion was set. The post does not rank this unit against other chippers, and customer feedback on the page was not used as evidence for any fact. Each claim taken from those factsheets is quoted in the notes file, and the quotes were checked against the saved text.
What we could not verify
- Cutting performance on dry or green wood. The listing states the intended material, and the sources opened do not address this model’s performance.
- How the unit handles green material in practice. The listing says efficiency may drop, with no figure.
- The 15:1 bullet against the 12:1 and 8:1 styles. The listing does not explain the relationship.
- Which of the two capacity figures is correct for your debris. The post reports both as stated.
- Warranty terms beyond the PDF link.
- Whether a given outlet and circuit suit a 15-amp motor. The listing states the voltage and gauge guidance, and the sources opened do not cover household wiring.
- Whether replacement blades and parts are available. Not stated in the text captured.
- Whether the 10.5-gallon bin is enough for a typical cleanup. The listing states the capacity and gives no cleanup volume.
FAQ
Can this chipper handle branches thicker than 1 inch?
Yes, according to the listing, which states sticks up to about 1.75 inches thick. Branches between 1 and 1.75 inches are inside the stated range. The listing also gives 1.5 to 1.8 inches in a bullet, so the upper limit is not fixed to a single figure.
Does it come with an extension cord?
No. The listing says the extension cord is not included. It gives guidance for a 12-gauge cord up to 75 feet, or a 10-gauge cord for longer distances, to avoid voltage drop, overheating and loss of power. The listing does not say whether any cord is sold with the machine.
Can it chip leaves?
The listing says it is not intended for leaves or fibrous plants such as corn stalks. It is designed for dry, seasoned branches and yard debris, so leaves are outside what the listing supports. Green or freshly cut material is covered by the listing’s dry-material note, which says it may reduce efficiency.
Is it battery-powered?
No. The listing describes a corded electric chipper with a 15-amp motor and a 120-volt product voltage. It names no battery for this model. Because the listing describes a corded machine, a battery pack is not part of this product’s stated setup.
What safety features does the listing describe?
The listing describes overload protection, a safety interlock switch between the cover and the main body, and a safety shutoff with a re-set button by the power button. Ohio State University Extension advises keeping hands and feet away from the discharge chute and moving parts, and wearing safety glasses with side shields or goggles and leather gloves. It also advises letting all internal machine parts come to a complete stop before opening the hood covering the disc or drum.
Is the mulch good for composting?
The listing says the chipper produces fine mulch for composting from dry, seasoned material, and that green material may reduce efficiency. The listing says the included 10.5-gallon bin collects mulch and compost quickly, but it gives no time figure. The listing makes no claim about compost time or quality, so this post does not give one.
Bottom line
Buy this corded chipper only if your debris is mostly dry branches and sticks up to about 1.75 inches thick, and you can run a 12-gauge extension cord from a 120-volt outlet to where the debris sits. If your debris is mostly green material or leaves, skip it.
