Ease of Use:






For more than a century, Dewalt has been the go-to brand for generations of homeowners looking to purchase power tools.

The brand has become synonymous with raw power and rugged durability.

And today, we’re going to look at one of Dewalt’s’ offerings, the Dewalt DCHT820P1.

About Dewalt DCHT820P1

The Dewalt DCHT820P1 is a 20V hedge trimmer with lots of awesome features to offer.

But will this hedge trimmer uphold to Dewalt’s tradition?

In theDewalt DCHT820P1 review section below, we shall explore everything you need to know about this hedge trimmer, including its features, benefits, and potential drawbacks. By the end of our review, you shall have decided whether the Dewalt DCHT820P1 is best for your needs.

Features and Benefits

1. Design

Sporting the familiar gold and black colors, the Dewalt DCHT820P1 is a candy to the eye.

More importantly, it offers the ideal blend of form and function.

Sure, the Dewalt DCHT820P1 is not among the most innovative equipment we’ve come across, but this battery-powered hedge trimmer is mechanically simple and will provide a straightforward operation.

Sporting all-plastic housing, nothing fancy, the Dewalt DCHT820P1 does not rattle during operation or feel cheap at all.

The plastic construction, however, is not a welcome on the handles and we would have loved to see a rubberized over molding on the grips for more comfort. Again, it’s a shame that the manufacturer has not included an adjustable or rotating handle for the ultimate convenience.

Regarding weight, this Dewalt hedge trimmer is not far off the standard weight metrics we’ve seen in most of the hedge trimmer.  With a modest weight of 11.5 pounds, it falls within the range of its competitors such as the BLACK+DECKER LHT2436 or the Husqvarna.

What this means is that the Dewalt will allow for continuous usage over an extended period without getting muscle fatigue. Equally, this model promotes portability and will allow to easily maneuvering through the bushes and shrubs with ease.

2. Blades

The blades are an essential component of a hedge trimmer.

The material construction of a blade plays an integral role in determining how durable your trimmer is and with the Dewalt, you get a durable steel blade.

Steel, unlike other materials, is highly reliable, does not rust, easy to sharpen and will provide you with years of reliable performance.

These blades are specially designed to cut twigs, branches, and even the moderate stems.

When it comes to the length of the blade, the Dewalt comes with a generous 22 inches blade. Though not the highest length we’ve come across, this length will allow you to reach the tall shrubs, while at the same time, providing you increased maneuverability and control.

According to the manufacturer, the Dewalt comes with a motor rated to give 2,800 SPM (Strokes Per Minute) and with this kind of power, it will allow you to easily slice through the thick branches that are up to ¾-inch thick.

3. Battery

Regarding power output, the Dewalt hedge trimmer boasts of 5.0 Ah Lithium-Ion Battery.

Unlike other forms of power, the battery provided by the Dewalt will provide you with incredible performance and generous run time.

Though the manufacturer has not indicated the actual runtime that this battery will provide, one of the users commented that a fully charged lithium-ion battery on the Dewalt will provide you with four hours give or take.

4. 20V vs. 40

When it comes to the battery, the Dewalt has similar specifications of BLACK+DECKER LHT2436 we had reviewed earlier.

The only notable difference between the two is probably the fact that BLACK+DECKER LHT2436 uses a 40V lithium-ion battery and the Dewalt uses a 20 lithium-ion battery.

The 40V battery is a tad expensive, and it might get you tempted into thinking it’s superior to the 20V on the Dewalt.

The truth of the matter is, the 20V battery does not skimp on performance, and will not provide you with less performance or less run-time as you would have expected. In any case, many of the reviewers comparing the two indicate there’s no notable difference between these two, and disparity arises dependent on the thickness or rather toughness of the branches you’re cutting.

So, you can expect the Dewalt to provide you with excellent performance, comparable to that of other higher-priced models.

5. Cordless

The Dewalt DCHT820P1 is a cordless hedge trimmer, and this means there’re a few restrictions on how to use this hedge trimmer.

Unlike the corded hedge trimmers, the Dewalt DCHT820P1 will not limit you on where to use it. Contrary to the electric hedge trimmers, the Dewalt DCHT820P1 will not restrict you to stay close to an electric socket.

6. Controls/Ease of Use

When it comes to ease of use, Dewalt features a host of convenient features that make the Dewalt an inspired choice for beginners or those with limited knowledge on hedge trimmers.

For instance, the controls on this hedge trimmer are oversized and simple to manipulate, and some of the users indicated that the Dewalt allowed them to control even when wearing a thick pair of gloves.

Also, the easy to access thumb switch will allow you to lock the trigger. Now, while some users are concerned with the placement of the switch, a majority of the users are pleased with the trigger as it provides them with the ability to reach the switch, regardless of how they’re holding the trigger.

Finally, the location of the battery on this unit will make it easier for the users to keep tabs on the battery’s power level when working.

Clearly, the DEWALT DCHT820P1 is one of a monster hedge trimmer that will provide you with a unique trimming performance.

Though the manufacturer has chosen not to pad the front grip, users have attested that it makes it easier for them to rotate the trimmer as needed.
