| Power Source | Battery Powered |
|---|---|
| Cutting width | 15 inches |
| Speed | 5800 rpm |
| Number of Batteries | 1 Lithium Ion (included) |
| Battery Average Life | 50 minutes |
The EGO POWER+ 15" cordless string trimmer is a battery-powered tool designed for routine lawn edging, trimming around flower beds, sidewalks, and fence lines. It uses a brushless motor and a Rapid Reload head, which makes swapping or reloading the .095" dual twist line quick during a session.

Choosing the Right String String Trimmer: Key Factors to Consider
Cutting Power and Line Speed
Cutting power determines how cleanly and quickly the trimmer slices through turf, weeds, and thicker stalks. Higher RPM and stronger motors let you tackle dense growth without multiple passes. For string-based heads, line speed affects how the filament cuts; faster spin gives a sharper bite but can use line quicker.
Assess the kinds of vegetation in your yard. A tidy lawn with light weeds needs far less power than a lot with woody stems or tall, damp grass. Choose a tool whose cutting capacity matches your toughest common task rather than the occasional overgrown patch.
Power Source and Run Time
The trimmer's power source shapes how you plan work sessions. Battery models offer quieter operation and lower maintenance, but runtime varies by battery capacity and motor efficiency. Consider whether a single battery will cover a full session or if you need swap-ready spares.
Gas models give extended runtime and more torque for heavy growth, but they require fuel mixing, tuning, and louder operation. Corded electric trimmers have unlimited run time but limit mobility and require access to outdoor power. Match the power type to your yard size, access to outlets, and tolerance for maintenance.
Ergonomics, Balance, and Weight
How a trimmer feels in use matters more than spec sheets. Weight distribution affects wrist and shoulder fatigue; a poorly balanced tool makes edging and overhead trimming tiring. Look for adjustable shafts, loop or bike handles, and shoulder strap compatibility to customize fit for your height and grip style.
Also consider vibration levels and trigger comfort. Softer grips, variable-speed triggers, and lower vibration translate to longer, more comfortable trimming sessions, especially for older gardeners or those doing larger areas.
Head Type and Line Feed Mechanism
The trimmer head determines how you feed new line and adapt to different cutting tasks. Bump-feed heads are simple and quick for midrange yards but can kick out more line than necessary. Automatic or tap-to-feed systems reduce interruptions during work. Fixed-line or blade attachments are useful alternatives for tougher weeds or thatching.
Ease of replacing or spooling line affects ongoing convenience. Some heads accept thicker or twisted line for heavy-duty cutting, while others are optimized for quiet, clean cutting with thinner line.
Maintenance and Serviceability
Routine maintenance affects lifetime cost and usability. For batteries, check availability of replacement packs and whether cells are user-swappable. For gas units, look at access to the spark plug, air filter, and carburetor for periodic service. Trimmers with simple, tool-free head replacement and accessible guards make routine care faster.
Consider how easy it is to find spare parts like guards, spools, and line cartridges. Tools that are easier to service mean less downtime and lower long-term hassle.
Durability and Weather Resistance
Garden tools face knocks from rocks, wet grass, and sun exposure. Materials and assembly quality determine how well a trimmer holds alignment, resists corrosion, and keeps controls working through seasons. Metal shafts and reinforced gear housings last longer in heavy use, while plastic gearheads may save weight but wear faster.
If you store equipment outdoors or use it in damp conditions, look for models with better sealing around electrical components and corrosion-resistant finishes.
Battery Versus Gas Versus Corded: Which Fits Your Yard
Match power type to task and yard layout. Battery trimmers excel for small to medium lawns and for gardeners who want quieter, low-maintenance tools. If you typically trim borders, around planters, and near noise-sensitive neighbors, a battery option often gives the best balance.
Gas trimmers remain useful for large yards with heavy growth or lots of woody stems. They deliver continuous power and longer single-session runtime but require fuel handling and periodic engine maintenance. Corded electric trimmers work well when you have easy access to outdoor power and mostly tidy, obstruction-free areas.
- Battery: quieter, lighter, limited by charge
- Gas: long runtime and torque, requires maintenance
- Corded: unlimited runtime, limited by reach
Shaft Styles and Handling for Different Tasks
Shaft length and curvature affect reach, balance, and tool control. Straight shafts provide better reach and tend to be stiffer for edging and cutting under low branches. Curved shafts can be lighter and easier to maneuver close to flower beds or for lower hand positions.
Consider adjustable-length shafts if multiple users or storage space are factors. A modular shaft that allows attachment swapping expands the tool's versatility for edging, pruning, or even hedge trimming with compatible implements.
- Straight shaft: longer reach, better for heavy-duty work
- Curved shaft: easier handling, better for small yards
- Adjustable shaft: shared use and compact storage
Line Choices and When to Use Thicker or Braided Line
Line diameter and profile change cutting behavior. Thicker line resists breakage in dense growth and around rough terrain where contact with rocks occurs. Twisted or braided line cuts more aggressively and lasts longer but can be louder and place more stress on the motor.
For fine edging and minimal line wear, thinner, round line is quieter and adequate. Match your line choice to the toughest recurring challenge in your yard rather than the easiest.
- Thin round line: quiet, good for light grass
- Thicker or twisted line: durable for weeds and rough ground
- Plastic or blade attachments: reserved for heavy brush and saplings
Noise, Neighbors, and Time-of-Day Considerations
Noise matters for early morning or late afternoon trimming. Battery and corded electric trimmers are noticeably quieter than gas two-stroke engines, making them better choices in noise-restricted neighborhoods or shared living spaces. Consider the timing of your sessions and local noise rules when selecting a power source.
If frequent trimming is part of your routine, a quieter tool increases flexibility and reduces friction with neighbors.
- Battery/corded: best for noise-sensitive times
- Gas: louder, schedule accordingly
- Muffling and aftermarket guards can help but do not eliminate engine noise
Storage, Transport, and Seasonal Care
How you store and move a trimmer affects longevity and convenience. Short-shaft or foldable models are easier to tuck into a shed or trunk, while full-length straight-shaft tools need wall hooks or floor space. Remove batteries for long-term storage and drain fuel from gas units to avoid varnish buildup in the carburetor.
Regular cleaning of the guard area and head prevents grass buildup that can clog the feed and cause uneven cutting. A quick inspection after each use saves bigger repairs later.
- Remove batteries or drain fuel for seasonal storage
- Clean spool and guard after use to prevent buildup
- Store vertical or on a wall hook to save floor space
How We Chose the Best String String Trimmer
We focused on attributes that directly impact real-world trimming chores. Primary evaluation criteria included cutting power and line feed reliability for consistent edge results, battery run time or fuel efficiency for realistic session lengths, and ergonomic handling to reduce fatigue during extended use. We also weighed head versatility and spool refill ease because those determine ongoing maintenance time, and build durability for resistance to common impacts and weather exposure. Tools were excluded if they were clearly aimed only at commercial landscapers, if key specs were missing, or if they lacked common safety features such as a reliable guard and bump/auto-feed mechanisms. Our selections prioritize models that balance performance and everyday practicality for home gardeners rather than professional-only performance extremes.
FAQ
How long will a battery trimmer run on a single charge?
Run time often depends on battery size and the intensity of use. Expect anywhere from 20 minutes for small batteries under heavy cutting to over an hour with higher-capacity packs in light trimming. Variable-speed triggers and lower line diameter extend usable time.
Can I use thicker line in any trimmer head?
Not always. Head design and motor torque limit the maximum line diameter. Using too-thick line can overload the motor or jam the head. Check the head specifications and pick line compatible with the feed system for reliable performance.
Is a straight shaft always better than a curved shaft?
Straight shafts give better reach and are often preferred for heavy-duty or professional use, while curved shafts are lighter and easier to handle for small yards. The best choice depends on your yard size, tasks, and personal comfort.
What maintenance keeps a trimmer running longer?
Regular cleaning of the guard, head, and spool area prevents grass build-up. For battery units, keep cells charged and stored in a cool, dry place. For gas units, use fresh fuel, clean the air filter, and service the spark plug as recommended.
Are attachments worth considering for a string trimmer?
Attachments add versatility and can replace separate tools for edging, hedge trimming, or light pruning. They are useful if you want a multi-tool solution and if the trimmer's drive shaft supports secure attachment swaps.
Final Verdict
Choose a trimmer by matching power and runtime to your yard size and toughest trimming tasks. Prioritize ergonomics and head design if you do frequent edging, and favor higher torque or thicker line options if you wrestle with woody or dense growth. Balance ease of maintenance and storage with the power you need so the tool stays in service longer. Ultimately, pick the configuration that reduces repeat work and physical strain while fitting your storage and noise constraints. Focus on the tradeoffs discussed here and you will end up with a String trimmer that makes outdoor upkeep faster and less taxing.
