The cc-equivalent spec printed on battery chainsaw boxes is doing a lot of marketing work and not a lot of honest communication. A saw rated at '80cc equivalent' doesn't cut like an 80cc Stihl — it means the manufacturer thinks its power output is in that neighborhood under ideal conditions. Don't buy on that number alone. What actually separates these saws is bar length, battery ecosystem, chain pitch, and how long they run before the power curve drops off.

The Contenders
EGO 56V 20" Chainsaw (CS2005)
Pros
- ✓55cc equivalent — strong enough for downed trees and firewood duty
- ✓Standard ⅜" pitch chain is easy to replace and sharpen anywhere
- ✓EGO's 56V ARC battery platform is one of the most mature in the cordless OPE space
- ✓20" bar handles most homeowner tasks without being unwieldy
Cons
- ✗6.0 Ah battery is on the smaller side — heavy users will want a spare
- ✗Premium pricing versus Ryobi for similar bar length
Greenworks Commercial 82V HOG 24" Chainsaw
Pros
- ✓24" bar and 80cc equivalent puts this in semi-pro territory
- ✓82V platform delivers the highest voltage of the group — real sustained cutting power
- ✓Built for commercial users who need to fell larger timber
Cons
- ✗82V is a niche ecosystem — your other tools probably aren't on it
- ✗Heavier and harder to maneuver for occasional use
- ✗Overkill and overpriced for the typical suburban homeowner
Milwaukee M18 FUEL 20" Dual Battery Chainsaw (2827-22)
Pros
- ✓Dual M18 FORGE XC 8.0 Ah batteries mean serious runtime
- ✓70cc equivalent and 0.325" pitch chain — a step up in cutting aggression
- ✓Ideal if you already own M18 tools and batteries
Cons
- ✗Two batteries required — the cost of entry is high if you're starting fresh
- ✗0.325" pitch chain is less common at hardware stores than ⅜" — minor but real annoyance
- ✗Heavier than single-battery alternatives
Ryobi 40V HP 20" Chainsaw (RY40HPCW03)
Pros
- ✓40V platform is widely available and affordable
- ✓20" bar for a 40V saw is respectable
- ✓Low-profile chain keeps weight and kickback down — good for newer users
Cons
- ✗52cc equivalent is the weakest of the group — struggles with hardwood or large-diameter cuts
- ✗Low-profile chain limits upgrade path for more aggressive cutting
- ✗Not the tool for anything heavier than storm cleanup and small tree work
DeWalt 60V FLEXVOLT 20" Chainsaw (DCCS677B)
Pros
- ✓60V FLEXVOLT is a powerful, well-supported platform
- ✓50.2cc equivalent handles real property work
- ✓20" bar and low-profile chain are a capable combo
Cons
- ✗FLEXVOLT batteries are expensive — the 15.0 Ah unit used in testing is a significant investment
- ✗Sold as a bare tool; battery and charger cost can easily double the price
- ✗If you're not already DeWalt, the ecosystem buy-in is hard to justify
The Insight Most Buyers Miss
Chain pitch matters more than voltage to your daily experience. The Ryobi and DeWalt both use ⅜" Low Profile chain — lighter, less aggressive, and sold everywhere. The EGO and Greenworks use standard ⅜", which is slightly more capable. The Milwaukee runs 0.325", which cuts well but is harder to find on a Sunday afternoon when you've thrown a chain mid-job. Check what your local hardware store stocks before you commit.
Who Should Skip What
The DeWalt DCCS677B is a genuinely good saw — but only if you're already running FLEXVOLT batteries across a tool fleet. Buying in cold just for a chainsaw means spending serious money on that 15 Ah battery before you've cut a single log. Similarly, the Greenworks 82V HOG is for people who mean business: landscapers, rural property owners, anyone regularly dropping trees over 16" diameter. The average suburban homeowner buying it for one downed oak after a storm is massively over-tooled.
