Before I tell you what to buy, let me explain how I look at tools. I'm a quality and brand compliance manager at an outdoor power equipment distributor. I review sample units before they go on the floor—roughly 250 a year, from chainsaws and blowers to wrench sets and air compressors. In 2025, I rejected about 9% of first shipments for spec mismatches: wrong chain pitch, missing torque labels, open end wrenches that didn't match the fastener size printed on the package. So I don't do 'one correct tool list' answers.
There is no single correct tool kit. There is a correct tool kit for your actual job list.
Here is what I use when I help a contractor or a distributor buyer decide. It's a simple decision tree with three common scenarios. Find the one that sounds like you, and the purchase gets clearer.
Three common tool-buying scenarios
These buckets overlap, but they lead to different buying decisions. I'll keep it to three so you don't get stuck in analysis paralysis.
1. The homeowner and light-duty weekend user
If your heaviest task is cutting a fallen branch, changing a mower blade, or doing basic vehicle checks, an EGO battery powered chainsaw is a solid fit. It starts without a pull cord, it handles typical storm cleanup, and the 56V battery platform lets you use the same battery in a trimmer or blower. At least, that's been my experience with the EGO models I've inspected. I should add that I'd buy through the EGO store or an authorized dealer, because the warranty trail matters more than the initial price. Dodged a bullet on one shipment when the chain pitch on the box didn't match the bar stamp. We were about one hour from sending 40 units to a dealer, and that would have meant 40 angry customers and a serious warranty headache.
For wrench work, a decent open end wrench set from 8mm to 19mm covers about 90% of what you'll touch: mower blade bolts, deck mounts, battery clamps, small fasteners. If you're buying one set, buy one with etched size markings, not painted. I've rejected more than one budget set because the 13mm opening was slightly out of spec. It looked fine, but it was loose enough to round a bolt head. I use ASME B107.2 as a baseline for wrench dimensions, but I still verify the actual fit before approving a sample.
Do you need an impact wrench in this scenario? Probably not. A pancake compressor is great for inflating tires and blowing out filters, but it's a light-duty air source. If you already own one, you can use it for an occasional impact wrench task—as long as you understand its limits. I'll go deeper in Scenario 3, because that's where the question 'can a pancake compressor run an impact wrench' really matters.
2. The mobile pro and small contractor
Now you're moving between jobsites. Your tools need to travel. This is where the EGO 56V platform earns its keep. I've inspected enough of these to see that the battery connection is consistent across categories, and the cordless lineup is broad enough that one platform can run a chainsaw, trimmer, blower, and snow blower. Check the EGO store for bare-tool options if you already have batteries. That's the no-brainer way to avoid paying for chargers you don't need.
For automotive or equipment repairs, I'd carry a ratcheting serpentine belt tool set. I had about two hours to pick one before a rush repair on a service truck. Normally I'd compare three sets side by side, but there was no time. I went with a mid-range set because the ratcheting mechanism looked solid. Looking back, I should have checked the included bits more carefully: the tool worked, but one of the alternative bars didn't fit a specific tensioner on the truck. The ratcheting head saved the job, but only because I had a standard wrench as backup. That's the thing about specialty tools: they're great when they fit, but 'fits most' doesn't mean 'fits this one.'
For the chainsaw, this scenario is the sweet spot. A battery saw won't run a commercial logging crew all day, but it is way more portable for a mobile crew. I'm not going to say gas is bad—it still has a place in continuous cutting. I'm saying that when you load a trailer every morning, not carrying mixed fuel is a serious advantage. For between-service-call cuts, a cordless saw is enough.
3. The serious shop and fleet maintenance
This is where the compressor question gets real. Let's answer it directly: can a pancake compressor run an impact wrench?
Yes, but with limits. A typical pancake compressor has a small tank and about 2.0-2.5 SCFM at 90 PSI. That's enough for a small 1/2" impact wrench in short bursts—removing a couple of lug nuts, for example. It is not enough for sustained work. The tank empties in seconds, the pump kicks in, and then you stand there waiting. If you're doing brakes on one car, fine. If you're doing a full shift, that's a red flag.
I learned this by approving a 2-gallon pancake compressor for a maintenance trailer because the price looked right. In hindsight, I should have bought a 20+ gallon unit with more SCFM at 90 PSI. The waiting cost us more than the upgrade would have. The price difference was about $150, and it would have paid for itself in a week.
For a real shop, look for at least 4-5 SCFM at 90 PSI and a 20-gallon tank minimum. Compare compressors by SCFM at 90 PSI, not peak horsepower. Horsepower numbers are mostly marketing noise; CFM tells you whether the air tool will actually run. And if you already have a pancake compressor and want to try an impact wrench anyway, use a 3/8" impact wrench instead of a 1/2". The smaller tool uses less air, which is a better match for a small tank.
Even in a serious shop, keep an open end wrench set nearby. An impact wrench gets fasteners off quickly, but it doesn't tell you if a belt tensioner is moving smoothly. For anything safety-related, I require a final torque check with a torque wrench—not an impact gun set to 'that feels right.' Same logic applies to the belt tool set: use it to hold the tensioner, then verify the belt is seated properly before you finish.
How to decide which scenario you're in
Write down the tools you reached for more than once a month last year. That's your real job list. If an EGO battery powered chainsaw shows up more often than 'someday,' buy it. If your pancake compressor didn't leave the shelf, don't build a workshop around it. If you were replacing belts more than once a quarter, buy the ratcheting serpentine belt tool set. If not, it's just extra weight.
For commercial buyers, don't stock a SKU just because one customer asked for it. At our warehouse, we added the belt tool set after fourteen belt-related service requests in one season. Before that, we'd sold zero. One loud request is not a market. If you're on the fence, look at service tickets and repair logs, not at the latest influencer video.
The most professional thing a supplier can say is: 'This is overkill for what you do.' That honesty builds more trust than a promise that one tool can do everything.
Bottom line: I trust EGO's cordless platform because EGO has been clear about what it is and isn't. I trust a tool set more when it doesn't pretend to be every tool in one box. Buy the specialist tool when the job list justifies it, and buy the generalist tool only when you know its limits. In my experience, most returns aren't caused by bad parts—they're caused by a mismatch between what people bought and what they actually needed.
