Gas vs Electric Chainsaw: Complete Side-by-Side Comparison
Gas chainsaws deliver more raw cutting power and full portability — the choice for felling large trees, storm cleanup, and remote work. Electric chainsaws (corded and battery) are quieter, lighter, lower-maintenance, and sufficient for most homeowner tasks including limbing, bucking, and small tree removal. For most homeowners with a single wooded property, a 40V–80V battery chainsaw handles 90% of the work at half the hassle.
Quick Comparison Chart

|---|---|---|---|
| Power output | Highest (2–7+ hp) | Moderate (12–15A) | High (40V–80V) |
| Bar length typical | 16″–36″ | 12″–18″ | 14″–20″ |
| Weight | 10–16 lbs | 7–12 lbs | 9–14 lbs |
| Portability | Fully portable | Limited by cord | Fully portable |
| Noise level | 105–110+ dB | 90–95 dB | 85–90 dB |
| Maintenance | High (engine, mix fuel, filters) | Low | Low |
| Price range | $200–$1,000+ | $100–$250 | $200–$700 |
| Best use | Large trees, remote, commercial | Small jobs near outlet | Homeowner, most residential tasks |
Gas Chainsaws: Pros and Cons
Advantages of Gas
- Maximum power: Gas saws produce 2–7+ horsepower, handling large-diameter trees and dense hardwood that would bog down smaller electric models.
- Full portability: No cord, no battery to charge — refuel and go. Essential for remote properties, off-grid locations, and heavy storm cleanup work.
- Longer continuous run time: A gas tank provides 30–45 minutes of continuous cutting on a full tank. Battery saws typically run 30–60 minutes per charge depending on load.
- Wider bar length selection: Gas saws are available with 18″–36″ bars for large timber work. Battery and corded models typically max out at 18″–20″.
Disadvantages of Gas
- High maintenance: 2-stroke gas engines require mixed fuel (50:1 gas-to-oil ratio), air filter cleaning, spark plug replacement, carburetor cleaning after storage. Fuel degradation is a persistent problem — see our guide on ethanol gas problems in small engines.
- Loud and heavy: Gas chainsaws generate 105–110 dB and weigh 10–16 lbs — mandatory hearing protection and operator fatigue are real considerations.
- Exhaust fumes: Cannot be used in enclosed spaces. Carbon monoxide buildup is a serious risk in garages or covered areas.
- Seasonal starting issues: After storage without fuel drain or stabilizer, gas saws frequently fail to start — carburetor cleaning required.
Battery Chainsaws: The Homeowner Sweet Spot
Battery-powered chainsaws from EGO, STIHL, Milwaukee, Husqvarna, and Greenworks have closed the power gap significantly. A 56V–80V battery chainsaw can fell trees up to 16″–18″ in diameter, handle all limbing and bucking work, and cut firewood for the season without the maintenance burden of a gas engine.
- Starts instantly: Press a button — no pull start, no warm-up, no flooding.
- Quiet enough for suburban neighborhoods: 85–90 dB vs. 110 dB for gas — a significant difference for early morning work or noise-restricted areas.
- Low maintenance: Keep the chain sharp, oil the bar, and store the battery indoors. That’s it.
- Modern high-voltage models (56V–80V) match mid-range gas performance: The EGO CS1804, Husqvarna T540i XP, and STIHL MSA 300 C-O are all capable of serious residential tree work.
The main limitations: higher upfront battery cost ($80–$200 per additional battery) and runtime limits on heavy continuous cutting sessions.
Corded Electric Chainsaws
Corded chainsaws are the budget option for light, near-outlet work — pruning, small diameter limbs, cutting firewood from a fixed pile next to the house. They weigh less and cost less than battery models but offer no portability beyond the cord length. For dedicated yard maintenance, they’ve been largely superseded by battery models that offer similar performance with full portability.
Safety: Both Types Require the Same Precautions
The power source doesn’t change the chainsaw’s fundamental hazard profile. A battery chainsaw cutting at 3,000 FPM chain speed is just as capable of causing severe injury as a gas saw. Both require:
- Chainsaw chaps or chainsaw pants
- Helmet with face shield
- Cut-resistant gloves
- Steel-toed boots
- Hearing protection (especially for gas)

Which Chainsaw Should You Buy?
| Your Situation | Best Choice |
|---|---|
| Homeowner: limbing, small trees, firewood from existing pile | 40V–56V Battery |
| Regular firewood cutting, trees up to 16″ diameter | 56V–80V Battery or entry gas |
| Felling large trees (18″+), storm cleanup, wooded land | Gas (16″–20″ bar) |
| Professional or commercial logging | Professional gas saw |
| Budget-limited, work near outlet, small tasks | Corded electric |
Frequently Asked Questions
Are battery chainsaws as powerful as gas?
Top-tier 80V battery chainsaws (EGO, Husqvarna, STIHL) approach the performance of mid-range 40cc gas saws in most residential cutting tasks. For felling trees over 20″ diameter or sustained heavy commercial cutting, gas still has the edge. For most homeowners, the difference is irrelevant.
How long does a battery chainsaw battery last?
Runtime depends on battery capacity and cutting load. A 5.0 Ah 56V battery typically provides 30–45 minutes of moderate cutting. For extended sessions, having 2 batteries and a rapid charger (30–60 minute charge time) keeps work flowing. See our full guide on cordless chainsaw battery life for details.
Can I use a battery chainsaw to fell a full-sized tree?
Yes, for trees with trunk diameters within the saw’s bar length capacity. A 16″ bar can fell a tree up to 16″ in diameter; you’ll need two cuts from opposite sides for larger trunks. Battery power is sufficient for the task — run time is the limiting factor for large-tree removal sessions.
Do gas chainsaws require premium fuel?
Most gas chainsaws require 87–89 octane regular or mid-grade gasoline mixed with 2-stroke oil at 50:1 ratio. Check your manual — some high-performance models specify 89–91 octane. Never use E15 or E85 ethanol blends in 2-stroke engines. See our chainsaw bar oil guide for the bar lubrication side of the equation.
Conclusion
For most homeowners, a mid-range battery chainsaw is the right choice — powerful enough for all residential tasks, easy to start, low-maintenance, and far quieter than gas. Choose gas if you need to fell large trees, work in remote locations without power, or cut large volumes of wood regularly. The power difference between modern battery and gas has never been smaller.
