Cordless chainsaws have gone from a novelty to a genuine replacement for homeowner gas saws in the last three years. EGO's CS1804 is the benchmark cordless chainsaw that changed many minds, and Milwaukee's M18 FUEL 2727 is the professional-oriented response. Both are serious tools. The distinction is battery platform integration and what you're cutting.
EGO CS1804
EGO CS1804 wins for homeowners wanting the best standalone cordless chainsaw; Milwaukee M18 FUEL wins for professionals already invested in M18.

Cutting Performance
The EGO CS1804 uses an 18-inch bar with a 56V brushless motor. Project Farm ran head-to-head cuts against comparable gas saws and found the CS1804 competitive with a 40cc gas saw through 12-inch hardwood. Chain speed and cutting confidence in bucking firewood logs are genuinely impressive.
The Milwaukee M18 FUEL 2727 uses a 16-inch bar driven by the M18 FUEL brushless motor system. Pro Tool Reviews found it slightly slower than the EGO through hardwood — the 16-inch bar and M18 voltage ceiling limit top-end cutting speed compared to EGO's dedicated 56V platform.
For limbing, pruning, and cutting logs up to 12 inches, both tools handle the work. For sustained bucking of large-diameter timber, EGO's higher-voltage motor and longer bar have an edge.
Bar Length and Capacity
EGO's 18-inch bar is the longest in the mainstream cordless class and allows cutting logs up to about 16 inches in diameter in one pass. This genuinely matters for firewood processing.
Milwaukee's 16-inch bar handles logs up to 14 inches in a single pass — enough for most storm cleanup and property maintenance. The shorter bar is slightly more maneuverable in brush and limbing situations.
If you're regularly processing logs over 12 inches, EGO's 18-inch bar is a meaningful advantage. For typical homeowner storm cleanup and limbing, both work fine.
Battery and Runtime
The EGO CS1804 ships with a 5Ah 56V battery and delivers approximately 300 cuts through 4-inch pine on a charge — ample for a weekend's firewood work. EGO's 7.5Ah battery further extends runtime significantly.
The Milwaukee 2727 runs on M18 HO batteries — the 12Ah High Output battery gives exceptional runtime. But the M18's lower nominal voltage means more battery draw per cut than EGO's 56V system.
For an operator already running M18 with 5Ah or larger batteries, the Milwaukee's battery integration is smooth. For a standalone purchase, EGO's included 5Ah battery delivers more runtime value out of the box.
Oiling System and Maintenance
Both chainsaws use automatic bar oiling with a translucent window to check oil level — a critical feature for chain and bar longevity. Both accept standard bar and chain oil.
Milwaukee's M18 FUEL 2727 has a tool-free chain tensioning system. EGO's CS1804 uses a tool-free tensioner as well. Routine maintenance — chain sharpening or replacement — is equally straightforward on both.
Neither tool requires the 2-stroke oil premixing that makes gas chainsaws messier to maintain. Both start instantly with no pull-cord ritual. If you've dealt with a stubborn gas saw on a cold morning, this difference is not small.
EGO CS1804 Strengths
- 18-inch bar — longest mainstream cordless option, handles larger-diameter logs
- 56V dedicated OPE platform — optimized for high-demand cutting tools
- ~300 cuts per charge on 5Ah — excellent standalone runtime value
Milwaukee M18 FUEL 2727 Strengths
- M18 battery compatibility — integrates smoothly with existing M18 tool collection
- Milwaukee M18 FUEL motor durability and 5-year warranty
- 16-inch bar is more maneuverable for limbing and brush work
EGO CS1804 Weaknesses
- EGO 56V is a separate platform — doesn't share batteries with other tools if you're on M18 or 20V
- Heavier than Milwaukee with large battery
Milwaukee M18 FUEL 2727 Weaknesses
- 16-inch bar limits single-pass capacity on larger logs
- M18's lower voltage ceiling limits top-end cutting speed vs EGO 56V
Best For
- a: Homeowners wanting a standalone best-in-class cordless chainsaw for firewood, storm cleanup, and property maintenance
- b: Professionals and contractors already running M18 who want cordless chainsaw capability without adding a second battery platform
FAQ
Can a cordless chainsaw replace a gas saw for firewood?
For a typical homeowner processing 1–2 cords per year, yes. Multiple battery packs let you work continuously while rotating charges. For commercial firewood producers processing 10+ cords, gas still has a runtime-per-refuel advantage.
Do cordless chainsaws require bar oil?
Yes — bar and chain oil is essential for both tools regardless of power source. Never run a chainsaw dry on bar oil.
Is the EGO CS1804 safe for overhead limbing?
Always follow kickback safety rules regardless of tool type. Both saws have chain brakes. EGO includes a lower-kickback chain; most experienced arborists replace it with a full-complement or full-chisel chain for better cutting performance.
