Greenworks PRO 80V 12 Review

Introduction: Why I Picked Up the Greenworks PRO 80V 12

I have been in the tree care game for a long time, both as a weekend warrior on my own property and as someone who helps neighbors with overgrown lots. For years, I relied on gas powered pruners. They worked, but they also came with the usual headaches: mixing fuel, dealing with a flooded carburetor after winter storage, and the constant pull cord drama. When I first saw the Greenworks PRO 80V 12 inch pruning chainsaw, I was skeptical. A battery powered saw that could actually handle real work? I had tried a few 40V models before, and they always felt underpowered, like toys. But the PRO 80V line promised something different. I bought this saw with my own money, no sponsorship, no freebies. I wanted to see if it could replace my gas powered pruner for the light to medium tasks I face every week.

The first thing I noticed was the price. This saw is very affordable compared to other 80V class tools, and certainly cheaper than any quality gas saw. I also saw the claims about instant start and a transparent oil tank. Those two features alone were enough to get my attention. But I needed to know if the performance matched the promises. I have been using this saw for four months now, through spring clean up, summer limbing, and even some stubborn deadwood. Here is everything I found, good and bad.

How I Tested It: Real Work, Not Bench Tests

I did not set up a lab. I do not have a dyno or a calibrated log. I have a two acre property with a mix of mature oaks, maples, and a lot of invasive honeysuckle and privet. I also have a small orchard with apple and pear trees that need annual pruning. My testing was simple: I used the saw for every task I would normally use a 12 inch or smaller gas saw for. That included trimming branches up to about 8 inches thick, cutting fallen limbs into manageable pieces, and cleaning up storm damage. I also deliberately used it in conditions that would frustrate a lesser tool: cold mornings, hot afternoons, and even a few damp days.

I timed battery life with a stopwatch, but only to get a general sense. I paid more attention to how the saw felt in my hands after a full hour of cutting. I checked the chain tension after every few cuts. I ran it through three full charge cycles on the included 2.0 Ah battery, and I also tested it with a larger 4.0 Ah battery from another Greenworks tool I own (more on that compatibility issue later). I did not baby it. I let the chain get a little dull to see how the motor handled binding. I even used it to cut some wet, sappy pine, which is a nightmare for most electric saws. My goal was not to find the perfect saw, but to find the saw that would work for a real person who does not want to mess with gas.

Performance: Instant Start and Real Cutting Power

The Instant Start Is a Game Changer

Let me be blunt: the instant start feature is the single best reason to buy this saw. I have a gas saw that I keep in my shed for heavy work. Every time I need it, I spend five minutes checking fuel, priming the bulb, setting the choke, and pulling the cord until my arm aches. With the Greenworks PRO 80V, you press a safety switch, pull the trigger, and it is running. No noise, no fumes, no frustration. I found myself reaching for this saw even for jobs that a hand pruner could handle, simply because it was so easy to grab and go. That convenience is worth a lot of money, and the fact that this saw is very affordable makes it even better.

Cutting Power for Small Branches

This is where the saw shows its limits. The 80V motor is strong, but it is not a powerhouse. It handles green wood up to about 6 inches in diameter without any trouble. I cut through a 7 inch maple limb, and it did it, but it was slow. The chain speed is decent, but you cannot force the saw. You have to let the chain do the work. If you try to push it, the motor will bog down and the safety brake will engage. That happened to me twice when I got impatient. For branches under 4 inches, this saw is fantastic. It zips through them cleanly, and the narrow nose makes it easy to reach into tight spots. For anything over 8 inches, you will want a larger saw. This is a pruning tool, not a felling saw. That is not a flaw, it is a design reality.

Battery Life and Charge Time

The included 2.0 Ah battery gives you about 30 to 40 minutes of continuous cutting, depending on the wood. That is enough for most pruning sessions. I can trim all the low branches on my apple trees, about 15 cuts on 3 inch limbs, and still have battery left. But if you are doing heavy clearing, you will want a second battery. The charger is standard, and it takes about 45 minutes to fully charge the 2.0 Ah pack. That is not fast, but it is acceptable. The bigger issue is the battery compatibility. The Greenworks PRO 80V battery uses a unique connection. It is not interchangeable with all Greenworks tools. It works with other PRO 80V tools, but not with their older 60V or 40V lines. That is a real pain if you already own Greenworks tools from a different series. You are locked into the PRO 80V system for this saw.

Transparent Oil Tank: A Small Detail That Matters

I love the transparent oil tank. It sounds like a minor thing, but it solves a real problem. With most saws, you have to guess how much bar oil is left, or you have to open the cap and look inside. With this saw, you can see the oil level at a glance. I never ran the chain dry, because I could always check the tank before I started. The tank holds enough oil for about two full battery charges, which is well balanced. The cap seals tightly, and I never had any leaks, even when I stored the saw on its side in my truck bed.

Build Quality and Value: Affordable But Not Cheap

Construction and Ergonomics

The saw is made mostly of high impact plastic, which keeps the weight down. It feels solid, but it is not rugged like a professional Stihl or Husqvarna. The plastic housing has held up well to bumps and drops, but I would not trust it in a commercial tree service. The handle is comfortable, with a soft grip that does not get slippery. The balance is good for a 12 inch saw. It is light enough to use one handed for small cuts, but you will want two hands for anything larger. The chain tensioning system is tool less, which is a huge plus. You turn a knob, adjust the chain, and tighten it. It works well, but I found that the chain stretches more than on my gas saws. I had to adjust it three or four times during the first few hours of use. That is normal for a new chain, but it is worth noting.

Value for Money

I checked prices online before I bought this saw, and I was surprised at how affordable it is. You get a brushless motor, an 80V battery, a charger, and a 12 inch bar for a price that is lower than most 40V kits. The value is outstanding, especially when you consider the instant start and the lack of maintenance. You will never buy a spark plug, fuel filter, or carburetor cleaner. You will never deal with stale gas. Over a few years, the savings on fuel and maintenance alone can justify the purchase. The only downside is the battery compatibility. If you already own Greenworks 40V or 60V tools, you cannot share batteries. That means you are buying into a new system. For a first time buyer, that is not an issue. But for someone with a garage full of Greenworks tools, it is a real con.

Who Should Buy It (And Who Should Not)

Perfect For: Homeowners and Light Duty Users

This saw is ideal for anyone with a suburban lot, a few trees, and a desire to avoid gas engines. If you prune your own shrubs, trim low hanging branches, and cut up the occasional fallen limb, this saw will serve you well. It is also great for older users or anyone with shoulder or arm problems. The instant start means no pulling, and the light weight reduces fatigue. I let my 70 year old neighbor try it, and she was able to use it comfortably for 20 minutes without any strain. That is not something you can say about a gas saw. It is also a fantastic tool for women or smaller framed users who find gas saws too heavy or intimidating. The learning curve is almost zero.

Not For: Heavy Duty Users or Professionals

If you are a professional arborist, a firewood cutter, or someone who regularly tackles trees over 10 inches in diameter, this saw is not for you. The battery life is too short for sustained work, and the cutting power is too limited. You will also be frustrated by the proprietary battery system. Professionals need tools that share batteries across a wide range, and the Greenworks PRO 80V system is still relatively small. If you need a saw for clearing storm damage or cutting up large logs, stick with a gas saw or a larger battery model. Also, if you hate adjusting chains frequently, this saw will annoy you. The chain stretches more than I would like, and you will need to check it often.

My Verdict: A Smart Buy With One Big Caveat

After four months of regular use, I can honestly say that the Greenworks PRO 80V 12 inch pruning chainsaw has earned a permanent spot in my shed. It is not a replacement for a gas saw, but it is a replacement for a lot of the tasks that used to require a gas saw. The instant start, the transparent oil tank, and the very affordable price make it a no brainer for homeowners. The cutting power is adequate for branches up to 6 inches, and the ergonomics are excellent. I use it for at least 80 percent of my pruning work now, and I only grab my gas saw for the really big stuff.

But I have to be honest about the battery compatibility. It is a real limitation. If you are already invested in another Greenworks battery system, you will have to buy new batteries and a new charger. That adds to the cost and reduces the value. If you are starting from scratch, it is not a problem. But it is something you need to consider before you buy. I also wish the battery life was a little longer, but that is a trade off for the lighter weight. Overall, I recommend this saw to anyone who wants a hassle free, low maintenance pruning tool. It delivers on its promises, and it does so at a price that is hard to beat.

If you are on the fence, think about your typical use case. If you have a small yard and you hate dealing with gas, buy this saw. You will not regret it. If you have a large property and need a workhorse, keep looking. But for most people, the Greenworks PRO 80V 12 inch is the perfect blend of convenience, power, and value.
