When choosing between a 16-Inch vs 12-Inch string trimmer, you face a trade-off between cutting efficiency and tool versatility. Both options are cordless and feature push-button line feed systems for convenient maintenance. The primary difference lies in the cutting width and power architecture. One unit is a specialized attachment for a multi-head system, while the other is a standalone 2-in-1 tool that also functions as a leaf blower. Your choice depends on whether you prioritize wider swaths or multi-tool functionality.

| Weight | 3.4 pounds | 10.4 pounds |
Which one should you choose?
Choose EGO Power+ 16-Inch Carbon Fiber Trimmer Attachment if
- You already own an EGO 56-Volt Power Head and want a wider 16-inch cutting swath.
- You prefer a lightweight carbon fiber shaft that weighs only 3.4 pounds.
- You need a dedicated trimmer attachment without the bulk of a leaf blower.
Choose WORX 12-Inch 20V Cordless Trimmer and Blower if
- You want a single tool that trims and edges with a 12-inch cutting width.
- You need a 360 CFM leaf blower for clearing debris from patios and driveways.
- You prefer a standalone 20V system that does not require a separate multi-head power unit.
Verdict: Choose the EGO attachment if you already have the compatible power head and need a wider, lighter cutting tool. Select the WORX kit if you want a versatile 2-in-1 solution that trims, edges, and blows debris without needing an additional power unit.
16-Inch vs 12-Inch Trimmer Specs
Cutting Width
The EGO Power+ STA1600 offers a 16-inch cutting swath, while the WORX WG928 provides a 12-inch cutting width. A wider swath means you cover more ground with each pass. This makes the EGO attachment better for clearing larger areas of grass or weeds efficiently. The WORX unit is narrower, which may be preferable for tight spaces or precise edging along borders. You choose based on whether speed or precision matters more for your yard size.
Power Source
These tools use different voltage platforms. The WORX WG928 operates on a 20V battery system. The EGO STA1600 is an attachment designed for the EGO 56-Volt Lithium-ion Multi-Head system. Higher voltage often translates to more power for tough jobs. If you already own EGO 56V tools, this attachment integrates seamlessly. If you prefer the 20V ecosystem, the WORX kit fits that setup. Your existing battery inventory will likely dictate which system you can use without buying new power sources.
Weight
Weight affects how tired your arms get during use. The EGO STA1600 attachment weighs just 3.4 pounds. The WORX WG928 kit weighs 10.4 pounds. The EGO unit is significantly lighter, making it easier to maneuver for extended periods. The WORX tool is heavier, partly because it includes a leaf blower component in the kit weight. For pure trimming tasks, the lighter EGO shaft reduces fatigue. You will notice the difference when holding the tool overhead or for long sessions.
Line Feed System
Both products feature push-button line feed systems for convenience. The EGO STA1600 uses POWERLOAD technology, which allows you to feed line by pushing a button. The WORX WG928 uses a COMMAND FEED system, also push-button operated. Both systems let you get fresh trimmer line on demand without bumping the head against the ground. This feature saves time and keeps you working continuously. Neither system requires you to stop and manually extend the line, making both options practical for regular use.
Versatility
The WORX WG928 is a two-tool kit that includes a 12-inch string trimmer and a 360 CFM leaf blower. This allows you to trim grass and then clear debris with the same battery system. The EGO STA1600 is a single-purpose attachment for the multi-head system. It does not include a blower. If you want to trim and blow leaves in one go, the WORX kit offers more utility. The EGO unit is specialized for trimming only, requiring separate attachments for other tasks.
Build Material
The shaft material influences durability and weight. The EGO STA1600 features a carbon fiber shaft. Carbon fiber is known for being lightweight yet extremely durable. The WORX WG928 does not specify its shaft material in the provided data, but it is generally plastic or metal composite. The carbon fiber construction of the EGO unit offers a professional-grade feel and resistance to corrosion. This may extend the lifespan of the trimmer head and shaft compared to standard materials.
Which string trimmer suits your yard
Users with large lawns needing wide cuts
The EGO Power+ STA1600 provides a 16-inch cutting swath, allowing you to clear more grass with each pass. Its carbon fiber shaft keeps the weight low at 3.4 pounds, reducing fatigue. The POWERLOAD system lets you feed line quickly. This setup maximizes efficiency for larger areas where covering ground speed matters most.
Those wanting a trimmer and blower combo
The WORX WG928 kit includes both a string trimmer and a 360 CFM leaf blower. This dual tool approach helps you trim edges and clear debris in one go. The 12-inch cutting width is sufficient for standard yard maintenance. You get two distinct functions without needing to purchase separate attachments or tools.
Users who need to edge sidewalks
The WORX trimmer converts to an edger by pivoting the head. This feature simplifies maintaining borders along walkways and driveways. You do not need a separate edging tool for this task. The push-button line feed ensures consistent cutting performance while you navigate tight edges and hard surfaces around your property.
