EGO Power+ CS1804 18-Inch 56-Volt Cordless Chain Saw

User Test Review

Got the EGO 18″ to replace a older 16″ battery-powered model that was leaking oil like crazy in order to clear and cut down the fallen trees on my land. The saw comes fully assembled, packaged and ready to use but you will need to add some bar and chain oil before getting started.

The EGO is one of the only battery-operated models that comes with an 18″ blade. The battery has a visible display that shows how much the battery is charged and changes throughout the charging process, upon inserting the battery in the charger, I saw it came already half charged.

At first use i notice that the battery is quite heavy, which adds to the overall weight of the product. However, the chain saw is exceptionally well balanced so you don’t really feel it and it is not any heavier than a standard gas saw. It is also possible to use ut with the EGO 2.5A battery for lighter weight, with a trade off that you cannot run the saw full speed.

The manual is pretty basic and pretty intuitive if you’ve used a chainsaw before. The saw works very well.  It’s relatively quiet, especially compared to a gas chains saw. Even if you use it early in the morning, your neighbors won’t complain.

My only complaint so far is that the battery life is somewhat different from what you see in the demo video. That said, a single charge can carve 25 feet of wood, and a 5.0Ah battery takes about an hour to charge. So in longer projects, I just take a break or do something else while the battery is charging. Also, running the saw at FULL throttle runs the battery down very quickly, so it is better to run it slower and let the chain do all the heavy lifting.

I also like the fact that it has an automatic chain tension system. On my old chainsaw and I believe most other brands, you need to turn a big knob to loosen the blade, then rotate a wheel until you get the tension YOU think is right, the EGO system is much better. Turn the large wheel and it will be tightened with the proper tension. If the resistance on the blade is too high, the motor will also stop for safety reasons.

It also has LED light built in wit has two settings and is incredibly bright, not sure if you need this feature, but it’s useful to know that it’s there when you need it. The 18″ version has almost double the RPM compared to the 16″ model and comes with a metal “bucking spike” not found on the 16″ model. When it comes to cutting, it’s incredible. To try it, I cut a 12-inch log and it literally cut like butter, it did not even take 10 seconds for each cut. Sure, I’m using a brand new blade, but with occasional sharpening I think all future cuts will be easier.

This is simply an incredible chain saw and the best price is currently on Amazon, about – $30 less than at Lowe’s.

Pros & Cons


  • More powerful than the previous generation Ego chainsaws.
  • Large oil container only needing to refill after running through roughly four 5.0 AH batteries.
  • Very quiet, able to use in a residential area early morning without complaint.
  • Can be used with shorter length bars, both 14″ and 16″ by following the Ego manual.
  •  Top-notch quality build.


  • Battery location, as it is placed on the underside it gets muddy and could easily be damaged. Some added protection would have been useful.
  • The larger battery is quite heavy and makes the saw a little harder to maneuver

  1. Hello,
    I bought a EGO CS1804 chainsaw with the 18 inch bar. Based on your review where you stated you could switch the 18 in with a 16 inch i also purchased a EGO 16 in bar and the correct EGO chain to fit. I tried to install the 16 inch bar and chain. It fit as the 18 inch did, However when i would reinstall the cover and turn the one large knob that attaches the cover and also adjusts the tension of the chain. It did not seem to fit right and the chain would not rotate freely. Please help.
