EGO Chainsaw Side-by-Side Comparison
Cutting Width
Edge: EGO Power+ 20-Inch Cordless Chainsaw
The EGO Power+ 20-Inch Cordless Chainsaw features a 20-inch bar, while the EGO Power+ 18" 56V Brushless Chainsaw has an 18-inch bar. A longer bar allows you to make single cuts through larger diameter wood. The 20-inch model handles bigger stumps and tree trunks more easily than the 18-inch version. If you frequently cut large branches or felling small trees, the extra two inches provide more capacity. The 18-inch model is sufficient for most yard debris and medium-sized limbs. Choose based on the maximum wood diameter you typically encounter.
Power Output
Edge: EGO Power+ 20-Inch Cordless Chainsaw
Both tools use a 56V brushless motor, but their performance ratings differ. The 20-inch model is rated as equivalent to a 55cc gas chainsaw with chain speeds up to 25 m/s. The 18-inch model is rated as equivalent to a 50cc gas chainsaw with chain speeds up to 22 m/s. Higher chain speed means faster cutting action. The 20-inch model delivers more raw power for tough cuts. The 18-inch model offers slightly less power, which may be adequate for lighter tasks. If you need maximum cutting speed, the 20-inch model has the edge.
Battery Runtime
Edge: EGO Power+ 18" 56V Brushless Chainsaw
Runtime depends on the battery used and the task. The 18-inch model can make up to 330 cuts on a 4×4 with the included 6.0Ah battery. The 20-inch model makes up to 135 cuts on a 6×6 with a recommended 6.0Ah battery. Comparing these directly is difficult because the test wood sizes differ. However, the 18-inch model shows a higher cut count on smaller wood. The 20-inch model is designed for heavier cuts, which drain battery faster. For extended use on smaller wood, the 18-inch model offers better efficiency.
Included Accessories
Edge: EGO Power+ 18" 56V Brushless Chainsaw
The 18-inch model comes with a 6.0Ah ARC Lithium battery and a charger. The 20-inch model does not include a battery or charger. You must purchase these separately for the 20-inch model. This makes the 18-inch model ready to use immediately. The 20-inch model is a body-only kit. If you already own EGO batteries, this matters less. Otherwise, the 18-inch model provides more value by including the power source. Check your existing battery inventory before choosing the 20-inch model.
Weight and Size
Edge: EGO Power+ 20-Inch Cordless Chainsaw
The 20-inch model weighs 12.7 pounds, while the 18-inch model weighs 28 pounds. The 20-inch model is significantly lighter. This makes it easier to hold overhead or maneuver for extended periods. The 18-inch model is heavier due to its included battery and possibly a more robust build. The 20-inch model is also longer at 39.8 inches compared to 36.3 inches. The lighter weight of the 20-inch model reduces user fatigue. If you plan to use the saw for long periods, the lighter option is better.
Chain Specifications
Edge: EGO Power+ 20-Inch Cordless Chainsaw
The 18-inch model uses a 3/8-inch low profile chain with 0.50-inch gauge. The 20-inch model uses a full chisel tooth chain with 3/8-inch pitch and 0.050-inch gauge. The 20-inch chain has a much thinner gauge, which reduces friction and power loss. The full chisel tooth design cuts faster than standard chains. The 18-inch chain is low profile, which may be safer for some users but cuts slower. The 20-inch chain is optimized for aggressive cutting performance. If you prefer faster cutting action, the 20-inch chain is superior.
Which EGO Chainsaw Fits Your Needs
