The Greenworks G-MAX 40V is an inexpensive blower that has an excellent runtime, is very ergonomic, and is one of the least loud products we have tested. In fact, it actually earned some of the highest scores of the entire group in three out of four of our metrics, which would lead you to think that the G-MAX should have earned an award or at least be a strong contender for one. Unfortunately, it did absolutely terrible in our power test, earning one of the lowest scores of the group and putting it in the back of the group overall. It might be an alright option if you don't want to spend a ton and only have extremely light debris to move but if that's not the case, then we would definitely recommend going with a different product.

Our Analysis and Test Results
This product finished overall just a few points behind the Ryobi RY40460 and ahead of the HUSQVARNA 320iB. Both the HUSQVARNA and the Ryobi are substantially more powerful than the G-MAX but the Greenworks has a way better battery life. Both the HUSQVARNA and the Ryobi are a bit more expensive but we would recommend either of them over the G-MAX unless you are just trying to dust off your porch or something similar.
We bought all of the cordless leaf blowers in this review and tested them side-by-side to see which ones are truly worthy of earning our recommendation. We divvied the various tests into four weighted rating metrics, with the G-MAX's results in each described below.
Accounting for half of the Greenworks' overall score, our power metric assessed just how much strength each blower has and how proficient they are at clearing leaves, litter, and other debris. Regrettably, the G-MAX did distinguish itself in this metric — not by doing well but by doing exceptionally poorly and earning a 2 out of 10.
For our first assessment, we measured how high the Greenworks could levitate a beach ball. It only managed to hold it at a distance of 22" from the nozzle, with the best blowers able to float the beach ball at heights of more than triple that.
Next, we spread out sand on the pavement to see just how far away the G-MAX could effectively move material. This is where this product really fell short compared to some of the other models, maxing out moving sand at a distance of a little more than 5' (64 inches). This is a drastically shorter range than the very best blowers, which could move sand almost 20' away!
When it came to clearing mixed debris from a section of our parking lot, the G-MAX did a pretty pitiful job. Its meager range means that you have to walk around quite a bit and makes it really time-consuming to clean larger areas. It also struggles to move heavier items or dirt that is stuck on.
After evaluating the power of each cordless leaf blower, our next metric focused on what makes them cordless: their battery system. This accounts for a quarter of the final score for the Greenworks G-MAX, which earned a 9 out of 10 for its phenomenal performance.
The Greenworks runs on a nominal voltage of 40 volts and includes a single 4 amp hour lithium battery. Starting with a battery with 100% charge, we were able to run the G-MAX for a whopping 38 minutes and 50 seconds — one of the longest runtimes of the entire group!
It's about average when it comes to recharging time for these products, with the included charger taking about two hours to completely refill a spent G-MAX battery.
Next, we graded and rated how comfortable and ergonomic the Greenworks is to hold and operate, which is responsible for 15% of its total score. It again did quite well, meriting an 8 out of 10.
This cordless blower is one of the lighter models that we have seen, only tipping the scale at 6 lbs. or so.
The G-MAX also has great balance, resting at a great blowing angle without much effort on your part at all.
Even better, you can reach the dial speed adjustment without any issues when holding it like this. However, you do need to use your other hand to turn the blower on or off.
For our final metric, we awarded points based on the noise levels produced by each cordless leaf blower, which is responsible for 10% of the final score. The Greenworks G-MAX finished with a strong showing, earning an 8 out of 10.
This leaf blower is fairly quiet for these products, only producing about 84.3 dBa for the operator. This drops off fairly quickly for bystanders, only registering 68.3 dBa for someone about 50' away.
The G-MAX is fairly inexpensive but it isn't very powerful, so it isn't the best budget buy out there.
We would readily recommend the G-MAX if it was a little more powerful but we just can't get past its pitiful performance at cleaning up debris in our tests.
