20v vs 40v hedge trimmer: what the voltage question really asks

Voltage here names the battery system the tool runs on; it is not by itself a power rating, and one voltage number does not mean one platform, since the listings below name two separate 20V systems. All four listings state battery power. Three of them state compatibility with DeWalt 20V MAX batteries, and the CRAFTSMAN states its V20 platform. No listing here states a 40V battery, so this guide rates no 40V machine and makes no 40V performance claim.

All four listings are tool-only. The battery and charger are sold separately or not included on every listing, so a buyer needs a battery on the same platform, either one already owned or bought separately. The listings do not state cross-compatibility between the CRAFTSMAN V20 platform and the DeWalt 20V MAX platform, so treat them as separate platforms when matching a battery to a tool.

The gear: four 20V trimmers in this guide

Tool	Blade	Cut capacity	Weight	Battery
DGQHME Hedge Trimmer	20 inches	3/4-inch	4.4 pounds	Not included
HEINPRO 22-Inch Hedge Trimmer	22 inches	5/8-inch	4.4 pounds	Not included
CRAFTSMAN V20 Hedge Trimmer	20 inches	3/4-inch	5.3 pounds	Sold separately
HEINPRO Mini 2-in-1 Trimmer	8.7 inches and 4.7 inches	Not stated	1.8 pounds	Not included

DGQHME leads this gear list on warranty and adjustability. Its listing states a pure copper motor delivering 3000 RPM, a 20 inch laser-cut diamond-ground blade that slices branches up to 3/4-inch thick, and a 180° adjustable cutting head with 5 positions (0°, 45°, 90°, 135°, 180°) for horizontal tops and vertical sides. It weighs 4.4 pounds, has an ergonomic soft-grip handle, a safety lock switch, a hand guard and included goggles, and is backed by a 24-month warranty with US-based customer support. Note a mismatch: the spec table lists dimensions of 8 x 9 x 7 inches while the title and bullets state a 20 inch blade, and this guide follows the title and bullets. The battery and charger are not included, and the listing states compatibility with the Dw 20V MAX battery platform.

HEINPRO 22-Inch Hedge Trimmer has the longest blade here at 22 inches, laser-cut, with a cut capacity of 5/8-inch. Its listing states a high-efficiency copper wire motor, overcurrent protection that shuts the tool off when voltage fluctuates, a full-length trigger with a soft rubber grip, a 180° rotating rear handle and a wrap-around front handle. It weighs 4.4 pounds with the battery not included, and states a 1 Year Manufacturer warranty. The listing states compatibility with DeWalt 20V MAX lithium-ion batteries, with battery and charger not included.

CRAFTSMAN V20 Hedge Trimmer is the bare-tool option on its own V20 platform. Its listing states 20-in. dual action blades with up to 3/4-in. cut capacity, a full wrap around handle, high carbon steel blades, and an integrated hook for the VERSATRACK Wall Organization System, with the system sold separately. It weighs 5.3 pounds, and the battery and charger are sold separately. No warranty term is stated in the listing data.

HEINPRO Mini 2-in-1 Trimmer has the lowest weight here at 1.8 pounds, with two blades: a hedge trimmer blade of 8.7 inches and a grass shear blade of 4.7 inches. Its listing states an upgraded copper wire motor, powder metallurgy gears pre-coated with grease, an aluminum bar on the long blade, and three safety features: a blade guard, a safety locking device and a soft start. Runtimes stated without load on a DEWALT 20V 2.0Ah battery are up to 120 minutes with the short blade and up to 80 minutes with the long blade. The listing states compatibility with DeWalt 20V batteries, with battery and charger not included, and states no warranty term.

What to check before choosing a higher voltage

Start with the battery platform already owned, since every listing here is tool-only. Then match the blade to the hedge: a longer blade covers more of a wide hedge face with each pass, while the mini blades suit fine buds, small lawns and edge work. Match cut capacity to the thickest branches on the property, and match weight to how long the work runs, since the listings here range from 1.8 pounds to 5.3 pounds. Finally, compare warranty terms, which here run from none stated to 24 months. Nothing here rates a 40V machine, so a buyer who wants 40V should look for a listing that states that platform and compare its stated blade, cut capacity, weight and warranty the same way.

Safety

Wear eye and hearing protection and sturdy shoes. Clear sticks, stones and other debris before trimming, and keep children, pets and bystanders away from the work area. The DGQHME listing includes goggles, with a safety lock switch and hand guard as stated features, and the mini listing states a blade guard, a safety locking device and a soft start. Follow the manual for the tool and the battery platform.
