EGO POWER+ ST1502SA Trimmer
The EGO POWER+ ST1502SA combines a 56V battery with a durable brushless motor for longer run times and lower vibration.

Buying decisions for a homeowner should balance power, weight, battery life, and storage needs. For those prioritizing easy edging and occasional heavy weeds, a corded option with a 14-inch swath may maximize reliability and consistent power, while cordless units offer mobility and ease of use in fenced yards or multi-zone properties. Tools with automatic line feeding minimize interruptions, and models with two-in-one trimming and edging features reduce equipment clutter.
Buying Guide
- Power source: Corded electric models deliver constant power but require a nearby outlet and cord management. Cordless models provide better mobility for lawns with multiple zones but depend on battery life.
- Cutting width: A 12–15 inch swath is typical for residential yards; larger swaths reduce passes but may increase weight.
- Line feed system: Automatic feed (AFS) reduces bumping and stops line from breaking mid-task, saving time.
- Weight and balance: Look for models with balanced designs to minimize user fatigue during edging and trimming.
- Two-in-one capability: Trimmer/edger combos save space and simplify storage, especially in smaller yards.
- Battery life and compatibility: If selecting cordless tools, consider common battery compatibility across tools to simplify charging and storage.
- Safety features: Dual-switch triggers, safety locks, and protective guards help minimize accidental starts and debris throw.
