Chainsaws are powerful tools that can help you fell trees, trim branches, and cut logs efficiently. When it comes to choosing between an electric or gas chainsaw, there are some key factors to consider including power, portability, maintenance, and cost. Keep reading as we compare the pros and cons of each type of chainsaw to help you determine which is the better choice for your needs.

Power
One of the most significant factors when choosing a chainsaw is the power and cutting speed it can provide. Gas chainsaws are more powerful than electric models and can cut through wood faster. Here’s a comparison of power between electric and gas chainsaws:
| Chainsaw Type | Power |
|---|---|
| Electric | Typically between 10 to 15 amps, which provides 1200 to 1800 watts of power. Less torque and lower chain speeds than gas models. |
| Gas | 2-stroke gas engines range from 35cc to 90cc. More torque and higher chain speeds than electric. More powerful overall. |
As you can see, gas chainsaws have a clear power advantage over electric. The gas engines can output significantly more torque and chain speed to rip through wood quickly and easily. This makes them preferable for heavy duty use like cutting down large trees or milling logs.
Cutting Speed
In line with their extra power, gas chainsaws can cut significantly faster than electric models. Gas chainsaws can achieve chain speeds of 45 to 60 feet per second depending on the engine size. Electric chainsaws typically top out at around 30 to 40 ft/s chain speed. The faster chain speed of gas models means you can get the job done quicker when felling trees or cutting firewood.
Portability
When it comes to lugging your chainsaw around the work site, electric models have the upper hand for portability. Here’s a comparison between electric and gas chainsaws on portability:
| Chainsaw Type | Portability |
|---|---|
| Electric | Typically lighter weight, ranging from 8 to 15 lbs. Don’t require fuel to be carried. Extension cord can limit range. |
| Gas | Heavier models ranging from 12 to 20 lbs. Fuel and oil must be carried as well. Can operate without cords. |
With their lighter weight and lack of need for fuels, electric chainsaws are generally easier to maneuver around a work site. You don’t have to worry about carrying extra gas and oil jugs or staying near a generator or outlet. However, the cord length does restrict how far you can roam from a power source.
Cord Limitations
Electric chainsaws do have some limitations when it comes to their cord length. Most electric models have a power cord of between 10 to 20 feet. This limits how far away from a power outlet or generator you can operate. While extension cords can provide more length, they also cause a drop in power over distance. Gas chainsaws have more freedom to roam far from a power source to cut in different areas.
Maintenance
To keep your chainsaw running properly for years to come, maintenance is required. Gas chainsaws typically need more frequent maintenance than electric models. Here’s a comparison of the maintenance needs:
| Chainsaw Type | Maintenance Requirements |
|---|---|
| Electric | Minimal maintenance needed. Requires sharpening or replacing chain. Oil reservoir needs periodic filling. |
| Gas | Requires more frequent maintenance. Air filters and spark plugs need regular replacement. Oil and gas mixes need preparation. More chain sharpening needed. |
With fewer engine parts and no need for filters, plugs, and fuel mixes, electric chainsaws tend to need less maintenance over time. You’ll spend less time on upkeep and repairs, which also saves on maintenance costs. Just keep the chain sharp, bar oil filled, and you’re good to go.
Air Filter Cleaning
One of the more tedious maintenance tasks on gas chainsaws is regularly cleaning or replacing the air filter. This is necessary to allow proper air flow to the engine. Electric chainsaws don’t have this extra filter cleaning requirement since they don’t rely on gas combustion engines.
Cost
When choosing between an electric or gas chainsaw, the purchase price and operating costs are factors to weigh. Here’s an overview of the costs associated with each type:
| Chainsaw Type | Cost Factors |
|---|---|
| Electric | Lower purchase price, around $100 to $300. Minimal fuel costs. Slightly lower maintenance costs. |
| Gas | Higher purchase price, $200 to $600. Recurring costs for gas and oil. Higher maintenance costs. |
Electric chainsaws are generally cheaper to purchase upfront. You’ll also save on fuel costs over the long run. While gas models require more maintenance and part replacements that add up over time. For the occasional user on a budget, the lower costs of an electric chainsaw may fit the bill.
Professional Use Costs
For professional use where a chainsaw is operated for hours every day, the long term costs of a gas model become more worthwhile. Even though gas chainsaws have higher initial and maintenance costs, their extra power and speed lead to increased productivity. So the higher costs can be offset by the ability to take on more jobs.
Safety
When operating a powerful cutting tool, safety is paramount. Both electric and gas chainsaws come with risks, but gas models present some additional safety concerns. Here’s an overview of safety considerations:
| Chainsaw Type | Safety Notes |
|---|---|
| Electric | Risk of electric shock if used improperly. Lower kickback risk. No engine fumes. |
| Gas | Risk of burns and fire from refueling. Engine fumes and carbon monoxide. More powerful kickback forces. |
Electric models eliminate the risks associated with an internal combustion engine. The biggest safety concern is avoiding contact with water sources and being aware of electrocution hazards from improper cord setups. Gas models require extra precautions when fueling and produce dangerous exhaust fumes.
Kickback Hazards
The more powerful gas chainsaw engines also increase the risk of kickback when the chain binds unexpectedly in the cut. The high torque can cause the bar to lurch back violently towards the operator if not handled properly. Electric chainsaws pose less of a kickback hazard by comparison due to their lower power.
Environmental Impact
When choosing a power tool, it’s worth considering the environmental footprint involved with its operation. Here’s a overview of the environmental considerations:
| Chainsaw Type | Environmental Impact |
|---|---|
| Electric | No direct emissions or fuel waste. Powersource may affect impact. Contains reusable materials. |
| Gas | Burning gas directly emits pollutants. More non-reusable parts. Fuel/oil residues are hazardous. |
Electric chainsaws themselves produce zero direct emissions and waste. However, the source of electrical power should be considered, such as whether it derives from fossil fuels. Gas chainsaws directly emit air pollutants from the engine exhaust. They also generate more plastic waste and hazardous fluids that require proper disposal.
Noise Pollution
Gas chainsaws produce significantly higher noise levels when running compared to electric models. The two-stroke engines generate up to 115 dB of sound. Electric chainsaws run much quieter, in the 85 to 100 dB range. Reducing noise pollution may be a consideration if you’ll be operating near others.
Conclusion
When choosing between an electric or gas chainsaw, there are compelling advantages and drawbacks for each to weigh. Gas chainsaws deliver much greater power and faster cutting speeds. However, they come at the cost of increased maintenance, safety hazards, environmental impact, and noise. Electric chainsaws provide quieter, cleaner, and safer operation at the expense of limited cord length and much lower power capabilities. For occasional light-duty use, electric models are likely the better choice for homeowners. Professionals who require high performance and the ability to work untethered will need the capabilities of a gas chainsaw despite the downsides.
