EGO Power Plus CS1804 18-Inch Cordless Chainsaw Review

Why you should trust this review

I bought this chainsaw and used it through a full season of real cutting, storm cleanup and firewood. EGO did not provide it and had no part in this review. Cordless outdoor power tools attract big claims about replacing gas, and the only way to test that honestly is to put the saw against the work a gas saw actually does, bucking sizable hardwood logs, clearing storm debris, cutting a meaningful amount of firewood, rather than slicing a few thin branches for a demo.

This is also a tool that demands respect and proper safety gear, and I used it as such. A season is enough to learn where a cordless saw genuinely matches gas and where the battery and weight remind you it is not gas. Everything below comes from that season of real cutting, including the honest limits.

How we evaluated

I used the CS1804 across a full season of homeowner cutting tasks: clearing downed limbs and trunks after storms, bucking logs into firewood, and the general property cutting that comes up through the year. The central question was whether it could handle real hardwood, so I cut oak logs in the 14-to-15-inch range, the kind of work that separates a serious saw from a trimming tool, and judged how cleanly and quickly it powered through.

I tracked runtime on the included battery across typical mixed work to give an honest figure, and separately noted how fast continuous heavy bucking drains it, since those are very different numbers. I assessed the practical handling, the weight with the battery, the electric start, and the tool-free chain tension and oiler, over real use rather than a single cut. The point was to evaluate it as a working saw for storm cleanup and firewood, under the conditions that actually test a chainsaw.

Cutting power on real hardwood

The cutting power is the headline, and it genuinely delivers. The combination of the 18-inch bar and the high-voltage brushless motor powered through 14-to-15-inch oak logs cleanly, with the kind of torque that lower-voltage cordless saws simply cannot produce. This is the test that matters: plenty of battery saws can nibble through soft branches, but cutting seasoned oak of that diameter is the work that defines whether a saw can stand in for gas, and the CS1804 did it without bogging down. Across the season it handled the heavy hardwood cutting I threw at it, which is exactly why it earns the claim of replacing a 40cc gas saw for homeowner use. For storm cleanup and firewood, it has the power the job needs.

Instant start and handling

The instant electric start is a genuine quality-of-life upgrade over gas. There is no primer, no choke, no pull-cord routine and no flooding the engine, you pull the trigger and it cuts. For intermittent work like storm cleanup, where you make a cut, move to the next limb, and cut again, that instant readiness saves real time and frustration compared with restarting a gas saw repeatedly. The tool-free chain tensioning and the easy oiler reservoir cap add to the convenience, letting you adjust and maintain the saw in the field without hunting for tools. These touches make the saw genuinely pleasant to grab and use for the stop-and-start nature of cleanup work, which is a big part of its everyday appeal.

Runtime and the battery system

Runtime on the included battery was solid for typical mixed work, enough to cut a meaningful amount of seasoned oak per charge before needing a swap or recharge. For the realistic homeowner pattern, some cutting, repositioning, hauling, that runtime covered real sessions without constant interruption. The honest caveat is that continuous full-throttle bucking, cutting one heavy log after another with no pause, drains the battery much faster, so for a big firewood day you will want a second battery on the charger. The upside is the battery ecosystem: the pack is shared across EGO’s broader cordless lineup, so if you own or plan to own other tools in the family, the batteries carry added value and a spare does double duty. That shared-battery flexibility is part of what makes the system worth buying into.

The honest tradeoffs

Two real downsides come with the territory. First, weight: with the battery installed, this saw is heavier than a comparable gas saw, and across a long cutting session that extra heft is noticeable in the arms and shoulders. It is manageable for homeowner work but worth knowing if you have a lot of overhead or extended cutting. Second, the kit is premium-priced, clearly more than a basic gas saw, because you are paying for the battery, the brushless motor, and the convenience. For someone who only needs occasional cutting, that price is a real consideration. Neither undercuts the saw’s capability, but they define the value equation: you are trading a higher upfront cost and some added weight for clean, quiet, instant-start operation with no gas, oil mixing, or engine maintenance.

Who should buy the CS1804?

Buy it if you do real homeowner cutting, storm cleanup and firewood, want gas-like power without the pull-cord, fuel, and maintenance hassle, and especially if you already own or plan to buy into the EGO battery system. For that use, it genuinely replaces a gas saw.

Skip it if you do heavy daily professional cutting where weight and continuous runtime matter most, you only need to trim small branches occasionally and the premium price is hard to justify, or saw weight is a real concern for you. Those cases point to gas or a lighter tool.

The verdict

After a full season of storm cleanup and firewood cutting, the EGO CS1804 is the cordless chainsaw I would recommend to homeowners who want gas-level capability without the gas hassle. The 18-inch bar and brushless motor cut through 14-to-15-inch oak cleanly, proving it can stand in for a 40cc gas saw on real work, the instant electric start is a genuine upgrade for stop-and-start cleanup, and the included battery covered meaningful cutting per charge. The honest tradeoffs are real weight with the battery installed, faster drain under continuous heavy bucking, and a premium kit price. For storm cleanup, firewood, and general property cutting, especially if you are in the EGO battery ecosystem, those compromises are well worth the clean, quiet, maintenance-free operation. It is the cordless saw that actually delivers on the gas-replacement promise for homeowner use.
