Our Verdict

If you're in the market for a professional-grade cordless chainsaw, we recommend the Greenworks Pro 80V. This saw cuts like a dream and it has a commendable runtime. Most of all, it has an insanely quick battery recharge time, meaning that you can spend less time watching the battery meter and more time getting your job done. The runtime and charge time coupled with several features such as a long bar, metal bucking spikes, a conveniently located battery compartment, an upright oil tank, and an easy-to-use chain tensioning system has made this version one of our favorites.

Our Analysis and Test Results

Founded in 2017, Greenworks is a brand that exclusively specializes in lithium-ion power tools. They have been on the cutting edge of battery technology since day one, which is clearly evident with their release of the Pro 18V. This 18" model winds up quickly, has a solid battery life, and great cutting performance. Where the Greenworks Pro 18V truly shines is its incredibly fast battery charge time.

Performance Comparison



Saw Performance


We weighted saw performance at 35% of our total score. For this first metric, we purchased a pile of Douglas Fir 4x4s from the lumber yard that we stacked on a sawbuck to create a repeatable test using the same type and size of dimensions of wood for each saw. We timed five cuts per model in order to get an average cutting speed for each one. The Greenworks Pro 80V showed fantastic results during this assessment — we measured an average time of 5.3 seconds per cut.


For the second half of the saw performance metric, we took the saws to a tree service job site to let the local crew get a feel for each model and provide us with some professional feedback. All agreed that the Greenworks Pro 80V performed similar to a two-stroke chainsaw, and the boys were impressed with the fact that an electric version could power an 18-inch chain. This model is less prone to binding and stalling than most of the other models that we've tested.

Ease of Use


For the ease of use metric we combined quantitative and qualitative analysis, this section accounts for 30% of our total score. We weighed and measured each saw in the lab before using our team of power tool specialists to note any details that help the user operate the device or tend to make it more of a pain. After carefully analyzing the Greenworks Pro 80V, we determined that this model deserves a 6 out of 10 for this metric.


The Pro 80V has several attractive features. We love that the bar & chain oil tank is oriented in an upright position with the cap on top. Most old-school chainsaws have the cap located horizontally near the bottom of the saw which makes it fairly awkward to fill and deal with. The tool-free chain tensioning system on this model is very elementary and requires little to no practice or training. Lastly, we are always fans of metal bucking spikes. This element aids immeasurable aids in cutting compared to plastic spikes or a complete lack of spikes.

One drawback we discovered is the redundant power button. The Pro 80V is already equipped with a thumb safety, a chain brake, and a throttle, so another button to push before the saw is operable can become annoying as it detracts from productivity.

This model did score some extra points for the location of its battery compartment. We have found that batteries that load into the top of the saw body are easier to use than those whose compartments are located on the sides or underneath the device.

The Greenworks Pro 80V is one of the heaviest saws that we've gotten our hands on. Tipping the scale at more than 15 pounds, be prepared to use a little extra gusto while wielding this model. Although it's not the ideal chainsaw for pruning a small tree, we should mention that the weight can aid in performance and reduce effort while handling jobs like bucking logs down to firewood size.

Battery


The battery metric comprises 25% of our total score. For this portion of our assessment, we began by fully charging each battery regardless of how much juice it came with from the factory. We then constructed a bench that allowed us to clip the throttle on each saw and time how long they could run with a chain installed, under no load. We were cautious about bar oil levels and stopped each device every 15 minutes to top the tanks off. Once the batteries were dead, we measured the charge time with the old trusty stopwatch.


The Greenworks Pro 80V ran for a commendable 27 minutes. Keep in mind, this is running nonstop. Realistically it will run for a solid couple of hours of making cuts. Although this isn't the longest-lasting battery we've tested, we'd still recommend this model for professional and heavy-duty use.


The main reason we gave the Greenworks Pro 80V an 8 out of 10 for this metric is its charge time. At a mere 30 minutes, you will barely have time to rest and eat a snack before it's time to get back to work. If you purchase two batteries to alternate between, this machine could be running all day.

Although this battery is massive, it charges in 30 minutes.

Noise


For the final 10% of our score, we measured noise levels. One of the greatest benefits of going with a cordless chainsaw is the reduction of noise when compared to two-stroke versions. For those with neighbors close by, it's nice to know that you aren't bothering anyone during their free time. Unfortunately, the Greenworks Pro 80V did not score very well for this metric. Earning a 6 out of 10, this model produces 86.8 decibels of noise from a few feet away. If volume levels are a concern for you, it'd be wise to go with a different model.


Value


Compared to the most expensive models, the Greenworks Pro 80V is absolutely affordable. Greenworks manufactures a ton of power tools — if you plan to buy a lawnmower, string trimmer, leaf blower, or another yard tool, you could increase your value by buying other tools that use the same battery and charger.

Conclusion


The Pro 18V is one of our favorite cordless chainsaws. We are always fans of metal bucking spikes and chain brakes, as these features aid in both safety and performance. It cuts well, it has a commendable battery life, and it has a ridiculously fast charge time. If you want a professional-grade saw but are sick of mixing gas and sucking fumes, this model is a fantastic choice.
