DeWalt 20V Chainsaw Review [DCCS620P1 Model] (2024)

Gas-powered chainsaw units are known for their superb performance, yet I’ve noticed the emerging popularity of newer, battery-powered saws which are garnering attention due to their affordability and efficiency.

In my review of the DeWalt 20v chainsaw, I meticulously evaluated the widely-recognized battery-powered DCCS620P1 to discern whether it truly is a powerhouse of a unit that delivers as promised, or simply another product buoyed by hype, lacking in both power and durability.



Design and Weight

In terms of weight, I was struck by the impressively light build of the DeWalt 20V cordless chainsaw. With the 5Ah battery included, the entire unit weighs just shy of 9 pounds. This puts it ahead of many other battery-powered chainsaws in terms of weight and makes it more akin to some of the smaller corded variants on the market.

It’s easy to use with one hand, so you can do one-handed cuts. Nevertheless, take the same precautions with gas chainsaws since these are heavy cutting equipment.

The body of the saw can be easily taken apart using straightforward knobs, eliminating the need for any tools. This design choice ensures that tasks like cleaning the saw, checking the oil, fixing the o-ring, and adjusting the chain tension can be done seamlessly, without the hassle of searching for tools.

A little lever next to the thumb must be depressed before you may pull the trigger. This prevents the saw from being turned on by accident if the handle is picked up. Though it may take some time, you will soon forget it’s even there once you’ve started using it.

DeWalt 20V Chainsaw Features

Overview of Specifications

Assembly and Preparations Before Use

There’s not much to do before using this chainsaw. If you’re gearing up for tasks like felling trees, there are only a handful of minor preparations to consider, such as topping up the bar oil. Much like other chainsaws, it features an internal reservoir designed to consistently lubricate the chain with oil, ensuring smooth operation.

You can access the bar and chain oil reservoir by turning a little lever on the oil cap on the left side of the saw. You might get the impression that this isn’t very sturdy, but you won’t have any issues with it. Adding an o-ring to the cap will ensure no leaks for over a year.

You should tighten the chain like gas saws, so it pulls easily but securely. Two knobs on the right side of the saw allow you to do this. 

To adjust the tension, loosen the bigger locking knob and then turn the smaller tension knob. The locking knob is then turned back to its original position and tightened.

Battery Power

Having extensively used these battery-powered saws, what genuinely impresses me is their power efficiency. With just a single charge of a 4Ah battery, I’ve been able to handle tasks like cutting medium-sized logs effortlessly.

And after putting it to the test numerous times, I can confidently vouch for the claim that it can make 90 cuts in pressure-treated 4 × 4 on a single charge. It’s as advertised.

Brushless Motor

Its extremely powerful brushless motor reduces friction and heat, extending battery life and cutting time. In addition, it shields the machine’s vital internal components from excessive heat, extending its useful life.

The brushless motor of this powerful chainsaw is efficient and powerful enough for demolition work [1], slicing beams, and cutting trees, respectively.

Bar and Chain + Chain Brake

I was pleasantly surprised by the quality of the included bar and chain. Not only were they top-notch, but the tension was also set just right out of the box. And if you have a preference for using a different component, the design allows for easy swapping with just a twist of a knob. It’s that intuitive.

However, tttempting to start the saw with the brake in the forward position (by pressing the trigger) will not yield any results. To engage the motor, you must pull the brake backward.

Tool-Less Chain Tensioning

A correctly tensioned tool guarantees a clean cut, stops the chain from getting clogged, and safeguards it from damage.

For this, it has a big knob on the side that you may turn to adjust the tightness. You can easily adjust the tension without going through your kit to find the tightening tool, a common problem with many machines. You can adjust from the top of the ladder, which is a convenient feature.


The chainsaw’s trigger operates in a “one-speed” fashion. Essentially, it comes down to two basic settings: on and off. So, no matter how you squeeze or release the trigger, the speed remains consistent. While this might sound limiting, for a saw of this size, it’s not a major concern. You can still modulate the speed to a degree by rhythmically pressing and releasing the trigger,

The trigger’s unlock button is located only on the right side, which may be inconvenient for left-handed users. You can see how this would be incredibly inconvenient for people who are left-handed to use.


Testing out this chainsaw was truly a delight for me. After calibrating the 5Ah battery system, starting the chainsaw was incredibly straightforward. With its lightness and without any resistance, I was able to cut through 10-inch-tall fallen trees with ease.

The Dewalt 20V Max XR is also a great tool for making clean cuts out of 12-inch logwood, and the blade will never slow down. Moreover, the Dewalt 20v can also chop down two medium-sized trees in a breeze.

Unlike a heavier gas chainsaw, you will not get fatigued or worn out by the Dewalt 20V unit. The chainsaw will not also do a terrible job of draining the battery.

Having tested and evaluated various models, this is undeniably one of the best lightweight battery-powered chainsaws I’ve encountered. It genuinely exceeded my expectations.

Ease of Use

In terms of ease of use, the chainsaw’s handle is padded and covered the whole way down.

Handling it vertically or horizontally is fine, and unlike a gas one, you don’t need to pull a string a few times to start it.

The tool also safeguards you while you’re in charge of it. A brake and safety switch are installed on the chainsaw to prevent accidental ignition.

Safety Features

The saw has both a standard mechanical chain break and an electric brake. The chain will immediately stop when your arm or kickback pulls the brake in front of your hand.

The low-kickback tip of the 12-inch bar reduces the risk of injury. However, you should still take precautions by reading the handbook and wearing safety gear like hearing protection, gloves, kevlar chaps, eye protection, etc., before using the DeWalt chainsaw for the first time.

Package Content

The chainsaw and its protective bar housing are both included in the package.

The Max XR 20V medium-size battery with a 5Ah capacity is also covered in your purchase. A user’s instructions and a few extras that may come in handy are also included in the package.

DeWalt 20V DCCS620P1 Alternatives

#1: Black & Decker LCS1240

Black & Decker LCS1240

If you’re intrigued by the cordless convenience of the DeWalt unit but have reservations about its power handling tougher tasks and larger trees, I’d recommend giving the LCS1240 a look.

In the same vein as the DCCS620 P1, these electric chainsaws also come with a 12-inch strong chain. Unlike the DeWalt, which is powered by a 20-volt battery, this unit is powered by a lithium-ion 40-volt cell, giving it increased power and making it better suited for denser and thicker woods.

#2: Oregon CS300-A6

Oregon CS300-A6

If you feel that the Dewalt model is a tad small for your requirements, I’d suggest checking out the CS300-A6. It’s a larger saw and might align better with your needs.

This Oregon chainsaw, like the DCC S620P1, features a robust bar guard and long-lasting construction. Yet, with its longer 16-inch chain compared to DeWalt’s 12-inch chain, this tool will quickly work on larger tasks and can cut through a whole tree like other chainsaws of its size.

#3: Greenworks 20262

Greenworks 20262

The Greenworks chainsaw is quite similar to the DCCS6 20P1 in that it has a 12-inch chain, a self-oiling reservoir, and a pitch of 0.375 inches.

However, the reduced runtime of only 65 cuts per charge compared to the DCCS 620P1’s 90 cuts per charge is a consequence of the lower-rated cell of 2.0 Ah compared to Dewalt’s 5.0Ah.

Review Conclusion: DeWalt 20V Chainsaw

After thoroughly testing the DeWalt 20V chainsaw, I can confidently say that it stands out in today’s market, not just for its efficiency but for its sheer versatility. While it effortlessly trims branches and smaller trees, it’s clear that it was designed to handle even more. 

Furthermore, its compact and clean design means I can easily bring it into my workshop or store it in my car without any worries about oil leaks!
