5 Best Cheap String Trimmer: Best Choices and Practical Tips

Finding the best cheap string trimmer is less about choosing the lowest-priced tool and more about matching the trimmer’s power, cutting width, battery system, and handling style to your yard. For most homeowners, the WORX 20V 12″ 2-in-1 Cordless String Trimmer is the strongest overall choice because it combines cordless convenience, an edging mode, two batteries, and useful angle adjustments. The BLACK+DECKER Weed Wacker with Auto Feed is the clear alternative if you prefer consistent power from an outlet and a wider 14-inch cut path.

The five options below cover simple electric trimming, compact cordless tools, multi-function garden equipment, and higher-speed battery models. Each one is ranked by its practical feature set, included equipment, ease of use, flexibility, and the trade-offs a budget-conscious homeowner should understand before buying.

You will learn which trimmer fits small yards, sidewalks, slopes, dense weeds, limited storage, and larger maintenance jobs. Because specifications and included accessories matter more than a single headline claim, the comparisons focus on cutting width, line feeding, runtime, adjustability, edging support, maintenance, and realistic ownership considerations.

Best Cheap String Trimmer: Quick Comparison

1. WORX 20V 12″ 2-in-1 Cordless String Trimmer

Check Price on Amazon

The WORX 20V 12″ 2-in-1 Cordless String Trimmer earns the top position because it offers the most balanced package for typical residential yard work. It converts from a string trimmer to a wheeled lawn edger in seconds, making it useful for both cleaning up grass around obstacles and creating straighter borders along sidewalks, driveways, and flower beds. The included rubberized wheels help guide the edger, while the adjustable spacer guard helps protect plants, ornaments, and other landscape features.

Its 12-inch cutting diameter is manageable in tight areas without feeling excessively slow for ordinary maintenance. The head tilts 90 degrees, which is helpful on sloped terrain and beneath low areas where a fixed head would be awkward. A push-button command-feed system releases line when needed instead of requiring the user to bump the head against the ground. WORX also includes two 20V Power Share lithium batteries, and those batteries can be used with other tools in the same WORX Power Share family.

The machine weighs 5.5 pounds and reaches a listed no-load speed of 7,600 rpm. That combination should appeal to homeowners who want a relatively light cordless tool rather than a gas-powered unit. It includes the charger, trimmer spool, support wheels, and safety guard, so the basic setup is complete.

The main limitation is its 0.065-inch line and 12-inch path, which are better suited to grass and routine weeds than extremely dense brush. Owners should also confirm compatibility before purchasing additional WORX batteries or accessories. For small and medium residential yards, however, its included dual-battery setup, edging guidance, and adjustable head make it the most versatile low-cost starting point.

2. BLACK+DECKER Weed Wacker with Auto Feed

Check Price on Amazon

The BLACK+DECKER Weed Wacker with Auto Feed is the clearest alternative to the WORX because it offers a wider cutting path and steady corded power without requiring battery charging. Its 14-inch swath can cover more grass in each pass, which is useful when maintaining a larger lawn edge or trimming open areas after mowing. Since it plugs into an outlet, it avoids the runtime limits that affect cordless models.

This model combines a string trimmer and wheeled edger. Rotating the tool converts it between modes, and the wheeled edge guide helps maintain a consistent border along sidewalks, beds, and other hard surfaces. Its automatic feed spool is designed to release line without the user repeatedly tapping the cutting head, helping reduce interruptions during a job.

A 6.5-amp motor and POWERDRIVE transmission are intended to provide stronger cutting performance through tough grass, weeds, and overgrowth than a very small basic trimmer. The adjustable handle and height positions also improve fit for different users. At the cord connection, a retention system helps prevent accidental disconnection, an especially useful detail when the tool is moved around corners or across a yard.

The trade-off is the power cord. You must work within the reach of a suitable outdoor extension cord, keep that cord clear of the cutting area, and store it separately. It is less convenient for scattered areas or properties without nearby outlets. The automatic feed can also use line differently from a manual bump-feed system, so keeping compatible replacement spools available is sensible. Choose this BLACK+DECKER when continuous plug-in power and a 14-inch path matter more than cordless mobility.

3. 20V Electric Cordless String Trimmer 2 X

Check Price on Amazon

The 20V Electric Cordless String Trimmer 2 X is a practical choice for users who prioritize compact storage and flexible positioning. Its shaft folds 180 degrees in three ways, making it easier to store vertically in a crowded garage, apartment, or small utility space. The head adjusts 90 degrees and the auxiliary handle rotates 180 degrees, so the tool can be positioned for slopes, corners, areas beneath benches, and other awkward spots.

A listed 9,500-rpm motor and 12-inch cutting width give it a useful balance between maneuverability and coverage. The manufacturer describes it as suitable for small yards and basic maintenance, including trimming tall grass and switching to an edging position with the pivoting head. It includes two 2.0Ah batteries and a charger, with a stated total runtime of up to 30 minutes. Having a second battery available can make short jobs less frustrating, although the actual working time will vary with grass density, cutting technique, and how often the tool is stopped.

The automatic line-feed system is designed to detect when more cord is needed. If the line breaks, the operating instructions require releasing the trigger, then pressing and holding the safety lock and switch together to reactivate the tool. That is useful to understand before the first job because the trimmer may not restart exactly like a conventional bump-feed model.

This model ranks below the WORX and BLACK+DECKER because its compact, relatively small-yard focus is more specialized and its battery capacity is modest. It is a good fit for apartment owners, occasional users, and homeowners with limited storage. Let the batteries cool for a few minutes after use, follow the charging directions, and do not expect a 12-inch cordless trimmer to replace a heavier brush cutter for thick woody growth.

4. 13″ Electric Weed Wacker

Check Price on Amazon

The 13″ Electric Weed Wacker stands out for offering more functions than a typical string trimmer. Its design can be configured as a string trimmer, lawn edger, mini lawn mower, or brush cutter. It also supports three cutting options: trimmer line, metal blades, and saw blades. That flexibility may appeal to a homeowner who wants one garden tool for grass edges, overgrown weeds, small shrubs, and light cleanup rather than separate equipment for each task.

The tool uses a listed 15,000-rpm brushless motor and a steel gear set. Those components are presented as ways to improve power delivery, smooth operation, and resistance to jamming. Its 13-inch cutting width is slightly broader than the 12-inch models here, while the adjustable head and telescopic pole help accommodate different heights and reach difficult corners or slopes. The stated machine weight is 5.2 pounds, which keeps it relatively approachable for routine yard work.

Two 21V 6.0Ah batteries and a matched charger are included. The larger stated battery capacity is attractive for longer jobs, though actual runtime still depends on the cutting attachment and workload. The package also includes replacement blades, trimmer line, a storage bag, and installation tools. A three-year warranty is listed for the main machine and a two-year warranty for the batteries.

Its lower ranking reflects complexity as much as capability. Switching between line, metal blades, and saw blades requires careful installation and attention to the correct guard and operating instructions. A multi-function tool may also be more equipment than someone needs for simple grass trimming. Before buying, confirm the intended attachment procedure and use the supplied protective equipment. It is best suited to owners who value versatility and are willing to manage more setup than a basic line-only trimmer requires.

5. 21V Cordless String Trimmer with 2 X

Check Price on Amazon

The 21V Cordless String Trimmer with 2 X is designed for users who want a broad cutting path and high stated motor speed in a cordless format. Its copper-wire motor is listed at up to 20,000 rpm, and the 14-inch cutting width can cover more ground per pass than the 12-inch compact models. That combination makes it appealing for medium-size residential areas where trimming open lawn edges would otherwise take longer.

Two 3.0Ah, 21V rechargeable batteries and a charger are included. The dual-battery arrangement supports longer work sessions and lets the owner keep one battery available while the other is charging. The head adjusts through 90 degrees, while the auxiliary handle rotates 180 degrees for different terrain and working positions. A detachable wheel assembly allows the tool to shift between a handheld trimmer and a wheeled configuration, which may reduce arm fatigue and improve stability when making longer, straighter passes.

The wheel design is intended to provide smoother operation, but it also adds another component to assemble, store, and keep clear of debris. The larger cutting width can improve efficiency, yet it may feel less nimble around dense plantings, narrow spaces, or delicate landscaping than a smaller head. High no-load speed should not be interpreted as permission to cut woody growth beyond the tool’s intended line-trimming use.

This model has a perfect listed rating, but the supplied review count is only 20, so there is less customer history to weigh than with the higher-ranked options. That limited sample is an important ownership consideration. Buyers should verify battery charging instructions, wheel attachment steps, replacement spool compatibility, and the seller’s support process. It is a promising fit for users who want cordless reach, a 14-inch path, and wheeled assistance, but a more established model may be preferable when long-term feedback matters most.

How to Choose the Best Cheap String Trimmer

A budget trimmer should make routine yard work easier without creating new problems involving batteries, cords, line, or difficult controls. The right model depends on the size and layout of your property, the kind of vegetation you cut, how often you work, and whether edging is a major part of the job.

Start with the power format

Cordless battery trimmers are usually the easiest to maneuver. They can reach the far side of a yard, move around trees, and operate without an extension cord crossing the lawn. That convenience comes with limited runtime, charging time, battery aging, and the need to keep track of compatible replacement batteries. A model supplied with two batteries, such as the WORX or the 20V Electric Cordless String Trimmer 2 X, can be more useful than a package with only one small battery.

Pay attention to the voltage and battery family rather than assuming batteries are interchangeable. The WORX batteries belong to the WORX Power Share system, while the other cordless models use their own stated battery formats. A battery that physically resembles another pack may not be electrically or mechanically compatible. If you already own tools from a battery platform, staying within that system can reduce future equipment costs, but only when the manufacturer specifically confirms compatibility.

Corded electric models do not have battery runtime limits and can provide consistent power throughout a job. The BLACK+DECKER is the corded choice here. You will need an appropriately rated outdoor extension cord, an outdoor outlet, and a safe plan for routing the cord. Never allow the cord to approach the rotating head, and stop to reposition it rather than pulling it forcefully around landscaping.

Match cutting width to the yard

Cutting width determines how much grass the trimmer removes in each pass. A 14-inch path, like the BLACK+DECKER and 21V cordless model, can be efficient along long borders and open lawn edges. A 12-inch path is often easier to control around posts, garden beds, trees, and narrow passages. The 13-inch multi-function model sits between those common sizes.

A wider path is not automatically better. It can require more motor effort in thick vegetation and may be awkward in tight spaces. For a small yard with many obstacles, control and low weight may matter more than clearing the maximum area per pass. For a property with long sidewalk edges, a wider head can reduce the number of passes.

Understand line feeding

Line-feed design affects both convenience and maintenance. The WORX uses a push-button command-feed system, allowing the operator to release line when needed. The BLACK+DECKER and the compact 20V model use automatic feed systems intended to reduce the need for bumping the head. Automatic systems can be convenient, but they may dispense more line than an experienced user would choose manually, depending on how the trimmer is operated.

Always use the line diameter and spool type specified for the tool. The WORX lists 0.065-inch line and a 10-inch cutting line length in its specifications. Do not substitute a thicker line simply because it appears stronger; oversized line can overload the motor or fail to feed correctly. Keep spare spools or compatible line available before the first major cleanup, especially during the growing season.

When line stops feeding, turn off the tool, remove the battery or disconnect the cord, and inspect the spool. Look for tangled line, a worn spool, grass packed around the head, or a cover that is not seated correctly. Never clear the cutting head while the trimmer is connected to power.

Consider edging and wheel support

Many inexpensive trimmers also serve as edgers, but their edging systems differ. The WORX uses rubberized wheels to guide the tool and includes a spacer guard for protecting nearby objects. The BLACK+DECKER has a wheeled edge guide. These features can make it easier to create a consistent line beside a sidewalk or flower bed than simply rotating a handheld trimmer by eye.

Wheeled support is most helpful on long, straight borders. It can be less useful around curved beds, steps, uneven rocks, or tight plantings. Detachable wheels, such as those included with the 21V cordless model, add versatility but require proper installation and storage. If you rarely edge, a simpler pivoting head may be all you need.

Look at adjustability and ergonomics

A trimmer should feel balanced while the head is held just above the ground. Adjustable shafts, handles, and heads allow the tool to fit different users and working positions. The WORX head tilts 90 degrees, the compact 20V model adds a 180-degree rotating handle, and the 21V model combines a 90-degree head with a 180-degree auxiliary handle. These adjustments can be particularly helpful on slopes or under low obstacles.

Do not judge comfort by weight alone. Battery placement, handle position, shaft length, and whether the tool can be guided by wheels all affect fatigue. A lighter model may be easier to carry, while a wheeled model may be more comfortable over a long straight edge. Adjust the shaft and handle before starting, keep both hands in the intended positions, and avoid twisting your torso to reach distant grass.

Choose the right tool for the vegetation

Most low-cost string trimmers are intended for grass, lawn edges, and ordinary weeds. They are not automatically brush cutters, even when marketing language uses terms such as heavy duty or high speed. Thick stems, woody weeds, vines, and small shrubs can consume line quickly or place excessive stress on the motor.

The 13″ Electric Weed Wacker is the only option in this group specifically supplied with line, metal blades, and saw blades. That gives it broader cutting potential, but it also makes correct attachment and guard use especially important. Use only the attachment recommended for the material, and do not treat a saw blade as a general-purpose substitute for a string head.

For normal grass, line is usually the simplest and least complicated option. Metal or saw attachments demand more attention to kickback hazards, surrounding objects, footwear, eye protection, and the manufacturer’s operating instructions. If your property has extensive brush, buying a purpose-built brush cutter may be safer and more practical than stretching a budget trimmer beyond its intended job.

Think about storage and ownership

Storage matters when a trimmer will live in an apartment, shed, or crowded garage. The folding shaft on the 20V Electric Cordless String Trimmer 2 X is especially useful for tight storage areas. Detachable wheels and included storage bags can also help, but accessories need a dedicated place so they are not lost between uses.

Remove batteries before storing cordless tools for an extended period unless the manufacturer directs otherwise. Keep batteries and chargers dry, away from extreme heat, and free from damaged contacts. Do not use a battery that is swollen, cracked, leaking, unusually hot, or otherwise damaged. Let a battery cool after demanding work before charging it, following the supplied instructions.

Clean grass from the guard, spool area, ventilation openings, wheels, and shaft after each session. A buildup of wet clippings can interfere with line feeding and add unnecessary load. Inspect the guard and handle for damage, check that fasteners remain secure, and replace worn line or blades before the next job. Basic cleaning usually takes only a few minutes and can prevent frustrating feed problems.

Use a safe trimming routine

Wear eye protection, sturdy closed-toe shoes, and clothing that will not hang near the cutting head. Keep children, pets, and bystanders away from the work area. Before trimming, remove stones, sticks, wire, and other objects that could be thrown by the rotating line or blade.

Hold the head parallel to the ground for ordinary trimming and use a controlled side-to-side motion. Avoid forcing the head into tall, wet, or dense grass. Work gradually through heavy growth rather than burying the line in one large clump. If the motor slows sharply, release the trigger and inspect the area instead of continuing to push.

For edging, use the wheel or guide when provided and move at a steady pace. Keep the spacer guard in place around delicate plants and decorations. If the trimmer vibrates unusually, makes a new noise, or loses power, stop immediately, disconnect the power source, and investigate. Continuing to run a damaged or obstructed tool can turn a minor maintenance issue into a more expensive failure.

Best Cheap String Trimmer FAQ

What is the best cheap string trimmer for most homeowners?

The WORX 20V 12″ 2-in-1 Cordless String Trimmer is the strongest overall choice in this group for typical residential maintenance. It includes two batteries, converts to a wheeled edger, has a 90-degree tilting head, and includes a spacer guard. Its 12-inch path is practical around landscaping, though it is not intended to replace a heavy brush cutter.

Is a cordless or corded cheap string trimmer better?

A cordless model is better when you need mobility and do not want to manage an extension cord. A corded model can be better for longer uninterrupted jobs near an outdoor outlet because it does not depend on battery runtime. The BLACK+DECKER provides the corded option here, while the other listed models are cordless.

What cutting width should a budget string trimmer have?

A 12-inch cutting width is a useful choice for small yards, tight spaces, and areas with many obstacles. A 13- or 14-inch width can cover open areas and long borders more quickly. Wider is not always easier to control, so choose based on the layout of your yard rather than the number alone.

Are cheap cordless string trimmers powerful enough for weeds?

They are generally suitable for grass, lawn edges, and ordinary weeds when used with the correct line. Dense brush, woody stems, and thick overgrowth may require a tool designed for heavier cutting. The 13″ Electric Weed Wacker includes blade options, but attachments must be installed and used according to its instructions.

How long should a cheap battery string trimmer run?

Runtime depends on battery capacity, vegetation, cutting width, line condition, and how continuously the tool is used. The compact 20V model lists up to 30 minutes of total continuous power from two 2.0Ah batteries. Treat that as a stated reference rather than a guarantee for every yard, and plan for shorter runtime in dense grass.

Can string trimmers also edge a lawn?

Several models can. The WORX and BLACK+DECKER use wheeled edging support, while other models switch to edging through an adjustable or pivoting head. Wheels can help produce straighter lines on long borders, but a pivoting head may be easier around curved beds and narrow spaces.

What should I check before buying replacement line?

Check the manufacturer’s specified line diameter, spool design, and replacement part information. The WORX lists 0.065-inch line. Other models may require their own spool format, so do not assume a generic spool will fit or feed correctly. Using the correct line helps protect the motor and reduces jams.

Final Verdict

The WORX 20V 12″ 2-in-1 Cordless String Trimmer is the best all-around budget choice because it combines two batteries, useful edging support, manageable weight, and flexible head adjustment. Choose the BLACK+DECKER instead when plug-in power and a wider cutting path are more important than cordless freedom. The remaining options make sense for compact storage, multi-function cutting, or a wider high-speed cordless setup.
