4 Best Kobalt Electric Weed Eaters 2025 in the United States

The Kobalt 40-Volt Max 15-in Straight Cordless String Trimmer is designed for users who already own Kobalt 40v batteries and chargers, as it does not include these components. This model is powered by a 40V battery, which should provide ample power for yards up to 1/2 acre. The adjustable cutting swath, ranging from 13 to 15 inches, allows users to choose between extended runtime and faster trimming, making it versatile for various tasks.

Its heavy-duty dual line feed system is effective for tackling tough grass and weeds with ease, and the bump head feature helps in seamless line feeding. The trimmer is relatively easy to start and operate with its variable speed trigger and two-speed settings, offering good control during use. Weighing 11 pounds, it is moderately heavy and this might be a consideration for users who prefer lighter tools for extended use. The adjustable shaft can aid in achieving a comfortable working position.

However, buyers must be aware that the battery and charger are not included, which means an additional purchase is necessary if one doesn't already possess these components. The trimmer also requires some assembly. This product is suitable for individuals who need a reliable and powerful trimmer and already have compatible battery equipment, but might not be the best choice for those seeking a complete kit right out of the box.

The Kobalt 24-Volt Max 12-inch Cordless String Trimmer is a lightweight, battery-powered tool designed for light to medium weed cutting tasks around the yard. Its 24-volt lithium-ion battery provides decent power for trimming small to medium patches of grass and weeds, with a 12-inch cutting swath that is ideal for maneuvering around tight spaces but may require more passes for larger areas. Weighing just over 10 pounds, it is comfortable to handle for most users, although the straight shaft design is fixed and does not offer adjustment options, which might affect comfort during extended use or when trimming near the ground. The battery is included, so you don't need to buy it separately, which is a plus for convenience.

The product uses a basic line feed system common in cordless trimmers, which should be straightforward but might require occasional manual line replacement. It is not the best choice for heavy-duty or professional use due to its moderate power and limited cutting width. This trimmer suits homeowners looking for an easy-to-use, cordless option for maintaining small yards and garden edges.

The Kobalt 40-Volt Max 13-in Straight Cordless String Trimmer is a solid choice for those who need a reliable tool for trimming tasks. It runs on a battery, which means it's cordless and offers more mobility compared to corded versions. However, the battery and charger are not included, so you will need to purchase them separately, which is an extra cost to consider.

The battery voltage at 40 volts is generally powerful enough for most residential trimming jobs, and the 13-inch cutting width allows for a decent reach, making your work efficient. The trimmer weighs 10.78 pounds, which is relatively manageable but could feel a bit heavy over extended use. Having an adjustable shaft is a big plus, as it allows you to customize the length to your comfort, making it easier on your back and arms.

The assembly is required, which might be a little challenging if you're not handy. Also, it's positioned at #210 in the string trimmers category, suggesting it's a popular, if not top-tier, choice. This Kobalt trimmer could be a great addition to your garden tools if you don't mind the additional purchase of a battery and charger and can handle a bit of weight.
