15-Inch vs 12-Inch Trimmer Specs
cutting width
The EGO Power+ ST1502SA offers a 15-inch cutting swath. This wider coverage allows you to clear more grass and weeds in a single pass. It uses a professional-grade 0.095-inch line. The WORX WG928 provides a 12-inch cutting width. This narrower path is often sufficient for tighter spaces or detailed edging. You can convert the WORX trimmer into an edger by pivoting the head. If your primary goal is rapid clearance of open areas, the extra three inches on the EGO model helps you finish tasks faster. For precise borders, the WORX versatility may be preferable.
voltage
Power source voltage indicates the potential energy available to the motor. The EGO Power+ trimmer operates on a 56V system. This higher voltage typically supports more robust performance for tough vegetation. The WORX kit runs on a 20V platform. While lower in voltage, it shares the PowerShare system with other WORX tools. This allows you to use the same batteries across multiple devices in your lineup. If you already own other 20V WORX equipment, the WORX trimmer integrates seamlessly. For maximum raw power per unit, the EGO 56V system holds the advantage.
motor type
The drive mechanism affects longevity and maintenance. The EGO Power+ features a high-efficiency brushless motor. Brushless designs reduce friction, which leads to lower vibration and increased reliability. This type of motor generally offers a longer lifespan compared to brushed alternatives. The specifications for the WORX WG928 do not explicitly state the motor type. You must assume standard brushed or unspecified technology based on the lack of data. For users prioritizing reduced vibration and extended tool life, the EGO brushless motor is the clear technical choice.
line feed system
How you reload trimmer line impacts your workflow. The EGO Power+ uses a Rapid Reload head. This system allows you to quickly and easily load new cutting line without complex steps. The WORX WG928 employs a Command Feed line system. This is a push-button mechanism that provides fresh line on demand. You do not need to bump the head to extend the line. Both systems offer convenience. EGO focuses on easy reloading, while WORX focuses on on-the-go extension. Neither system is objectively superior without knowing your preference for bump-feed versus push-button.
runtime
Battery capacity determines how long you can work before recharging. The EGO Power+ includes a 2.5Ah battery. It delivers up to 45 minutes of runtime on a single charge. This is sufficient for medium-sized yards. The WORX kit includes two batteries, but the specific amp-hour rating is not listed in the provided data. We cannot calculate the exact runtime for the WORX model. However, the EGO specification is clear and substantial. For predictable, documented endurance, the EGO 45-minute runtime is the verifiable advantage.

Buyers wanting a trimmer and blower combo

Those prioritizing lightweight handling and versatility
