The mower is lightweight and easy to maneuver, though its plastic construction might feel less sturdy.

The WORX WG927E 40V Cordless Lawnmower & Trimmer Twin Pack is a comprehensive kit designed for medium-sized gardens up to 230㎡. It includes a 40V cordless lawnmower and a 20V cordless grass trimmer, both battery-powered, making it an environmentally friendly and cost-efficient option. The inclusion of 2x 2.0Ah batteries and a dual charger ensures that your tools are always ready for use without the need for fuel or cumbersome cords.

The PowerShare battery compatibility is a convenient feature, allowing interchangeable use between different WORX tools. The lawnmower features a cutting width of 34cm and comes with six adjustable cutting height positions, which enables customization based on your lawn's needs. The grass trimmer has a cutting width of 25cm and is designed to reach difficult spots and maintain neat edges effortlessly. The cordless design of both tools offers freedom of movement, making them user-friendly even for beginners.

Weighing 17.6kg in total, this twin pack is relatively lightweight, considering it includes both a mower and a trimmer. However, the 20V battery for the trimmer might fall short for larger tasks, and the lawnmower's performance may vary based on grass thickness and height. In conclusion, this twin pack is ideal for those looking for a versatile and efficient solution for medium-sized garden maintenance with the added benefit of environmentally conscious design.

Despite the meaty battery, the trimmer remains lightweight and comfortable to handle, even for extended periods.

The Bosch Cordless Grass Trimmer EasyGrassCut 18V-26 is designed for small to medium-sized gardens and offers several convenient features. It has a cutting width of 26 cm, which is suitable for typical garden maintenance tasks. Weighing only 1.9 kg, its lightweight design allows for comfortable handling, reducing fatigue during prolonged use.

The powerful motor delivers a speed of 9000 RPM, ensuring efficient trimming performance. Additionally, the trimmer includes a continuous cutting system that feeds the line with each release of the trigger, minimizing interruptions during work. The ability to switch between trimming and edging by simply twisting the handle and clicking a button adds versatility to its functionality.

It’s important to note that the trimmer does not come with a battery, which needs to be purchased separately, potentially increasing the cost. The absence of an included battery also means users must ensure compatibility with Bosch’s 18 Volt system. If you’re looking for a lightweight and versatile battery-string trimmer for maintaining a small to medium-sized garden, this Bosch model could be a good option.

Buying Guide for the Best Battery String Trimmers

Battery-powered string trimmers are a great choice for maintaining your lawn and garden. They offer the convenience of cordless operation, making them easy to maneuver and use without the hassle of dealing with gas or power cords. When choosing a battery string trimmer, it's important to consider several key specifications to ensure you get the best fit for your needs.
Battery VoltageBattery voltage determines the power output of the trimmer. Higher voltage batteries provide more power, which can be useful for tackling thicker grass and weeds. Common voltage ratings range from 18V to 80V. For light trimming and maintenance, a lower voltage (18V-24V) may suffice. For more demanding tasks, consider a higher voltage (40V-80V) to ensure efficient performance.
Battery Capacity (Ah)Battery capacity, measured in ampere-hours (Ah), indicates how long the battery can run before needing a recharge. Higher capacity batteries (e.g., 4Ah or 5Ah) will last longer, allowing you to complete larger jobs without interruption. If you have a small yard or only need occasional trimming, a lower capacity battery (e.g., 2Ah) may be adequate. For larger areas or frequent use, opt for a higher capacity battery to avoid frequent recharging.
Cutting WidthCutting width refers to the diameter of the area the trimmer can cut in a single pass. Wider cutting widths (e.g., 14-16 inches) allow you to cover more ground quickly, making them ideal for larger lawns. Narrower cutting widths (e.g., 10-12 inches) offer more precision and are better suited for smaller areas or detailed work around flower beds and edges. Choose a cutting width based on the size and type of area you need to trim.
WeightThe weight of the trimmer affects how easy it is to handle and maneuver. Lighter trimmers (e.g., 5-7 pounds) are easier to use for extended periods and are less tiring, making them suitable for users who may have limited strength or endurance. Heavier trimmers (e.g., 8-12 pounds) may offer more durability and power but can be more challenging to use for long durations. Consider your physical capability and the amount of time you plan to spend trimming when choosing the weight of the trimmer.
Adjustable ShaftAn adjustable shaft allows you to change the length of the trimmer to suit your height and reach. This feature is important for comfort and ergonomics, ensuring you can use the trimmer without straining your back or arms. If multiple people will be using the trimmer, or if you need to reach different areas, an adjustable shaft can provide the flexibility needed for a comfortable trimming experience.
Line Feed SystemThe line feed system determines how the trimmer's cutting line is advanced. There are manual feed systems, bump feed systems, and automatic feed systems. Manual feed requires you to pull out the line manually, bump feed advances the line when you tap the trimmer head on the ground, and automatic feed advances the line automatically as needed. Automatic feed systems are the most convenient and user-friendly, while bump feed systems offer more control. Choose a line feed system based on your preference for convenience and control.
