Introduction
The mini chainsaw market has exploded in recent years, with dozens of manufacturers offering compact, battery-powered saws for light pruning and yard cleanup. The Worx WG322 stands out in this crowded field as one of the most refined and capable options — a 20V battery mini chainsaw that balances power, weight, and runtime in a package that’s easy to recommend for homeowners.
We’ve tested the WG322 on the tasks it was designed for — pruning fruit trees, trimming branches, and general yard cleanup. The results are impressive for a saw of this size. It won’t replace a full-size chainsaw for heavy cutting, but for light pruning and trimming, it’s one of the best options available.
Key Advice: The WG322 is a specialized tool for light pruning. If you need to cut anything larger than 4 inches in diameter, step up to a 16-inch battery or gas saw. The WG322 excels at what it’s designed for — don’t ask it to do more than it was built to do.

Technical Engineering Deep-Dive
The 20V Brushless Motor
The WG322 uses a brushless motor that delivers more torque and efficiency than the brushed motors found in cheaper mini chainsaws. At 20V, the motor produces enough power for branches up to 4 inches in diameter without significant bogging. The brushless design extends motor life and reduces maintenance — there are no brushes to wear out or replace.
The motor controller manages power delivery based on load, gradually reducing output when the saw encounters heavy resistance rather than cutting out suddenly. This gives the operator time to finish a cut and reposition — an important safety feature when you’re working overhead or in awkward positions.
20V Battery System
The WG322 is part of Worx’s 20V PowerShare battery platform. The same batteries work across Worx’s entire 20V tool lineup — drills, impacts, blowers, and more. For homeowners who already own Worx 20V tools, the WG322 can use existing batteries, reducing the overall cost.
The 2.0Ah battery provides approximately 20-30 minutes of intermittent light pruning. The 4.0Ah battery doubles this runtime but adds some weight. For most residential pruning tasks, a single 2.0Ah charge is sufficient.
Compact Design
At 8 inches, the WG322’s bar is small enough to reach into tight spaces that full-size saws can’t access. The compact design makes it easy to maneuver around fences, raised beds, and other obstacles. The overall length is short enough for comfortable one-handed operation during light pruning.
Key Features
Brushless Motor
The brushless motor delivers more torque and efficiency than brushed motors, extending battery life and motor life. It also runs cooler, reducing the risk of thermal shutdown during extended use.
Tool-Free Chain Tensioning
The WG322 features a side-access chain tensioner for quick field adjustments. No tools required — just turn the tensioning knob until the chain sits properly against the bar.
Safety Features
The saw includes a chain brake and handguard for kickback protection. The chain brake stops the chain quickly if kickback occurs, and the trigger lockout prevents accidental activation during transport.
Lightweight Design
At 7.0 lbs with battery, the WG322 is light enough for extended one-handed operation. This is a significant advantage for users who need to do a lot of pruning or trimming in a single session.
Hardware Specifications

Maintenance & Serviceability
The WG322 is a low-maintenance saw:
- Chain: Sharpen with a 5/32” round file or replace when dull.
- Bar: Flip or replace when worn.
- Oil: Keep the reservoir full with standard bar and chain oil.
- Battery Care: Store at room temperature. Avoid full discharge before recharging.
There’s no carburetor to clean, no spark plugs to gap, and no fuel to mix. The only regular maintenance is keeping the chain sharp and the oil reservoir full. For users who want a saw they can grab and use without fuss, the WG322 delivers.
Performance Analysis
Pruning and Trimming
This is the WG322’s sweet spot. The 8-inch bar reaches most pruning targets, and the lightweight design lets you make hundreds of cuts without fatigue. The brushless motor delivers enough power for branches up to 4 inches in diameter without significant bogging.
Small Tree Trimming
The WG322 can trim small trees and large shrubs with ease. The compact design makes it easy to reach into the canopy, and the quiet operation means you can work early without disturbing neighbors.
Yard Cleanup
For general yard cleanup — removing fallen branches, trimming overgrown shrubs, and clearing brush — the WG322 is an excellent tool. The instant-on capability means you can make quick cuts without wasting time starting an engine.
Limitations
The WG322 is not designed for heavy cutting. It can’t handle tree felling, firewood processing, or cutting wood over 4 inches in diameter. The 8-inch bar limits reach, and the 20V motor lacks the power for sustained heavy use. For these tasks, you’ll need a more powerful saw.
Pros & Cons
Pros
- Ultra-Lightweight: 7.0 lbs with battery makes it easy to use with one hand.
- Brushless Motor: More efficient and longer-lasting than brushed motors.
- 20V PowerShare: Compatible with Worx’s entire 20V tool lineup.
- Quiet Operation: Significantly quieter than gas saws.
- Low Maintenance: No fuel mixing, carburetor adjustments, or spark plugs.
Cons
- Limited Power: 20V motor limits cutting capacity to 4 inches or less.
- 8-Inch Bar: Limited reach for larger branches or trees.
- Runtime: 20-30 minutes per charge limits extended use.
- Not for Heavy Cutting: Won’t handle firewood processing or tree felling.
Final Verdict
The Worx WG322 is one of the best 20V mini chainsaws available. It delivers genuine cutting performance from a lightweight, compact design that’s perfect for light pruning and yard cleanup. The brushless motor provides the power needed for branches up to 4 inches, and the 20V PowerShare battery platform offers excellent value for homeowners who already own Worx tools.
It won’t replace a full-size chainsaw for heavy cutting, but that’s not its purpose. The WG322 is a specialized tool that excels at what it’s designed for — light pruning, trimming, and yard cleanup. For homeowners who want a lightweight, low-maintenance saw for occasional use, the WG322 is an excellent choice.
