Buying Guide: How to Choose the Best Cordless String Trimmer
I’ve spent a lot of time testing and using cordless string trimmers, and I can tell you that not all of them are created equal. The best one for your neighbor might be a poor fit for your yard. To find the right tool for you, there are a few key factors you need to consider before you click that “buy” button.
First up is power source. You’ll find models that use a single, powerful battery and others that use two smaller batteries. Single-battery systems are often lighter and more balanced, making them easier to handle for longer periods. Two-battery systems can sometimes offer more raw power, but they add weight. Think about your yard’s size and how long you typically need to work. If you have a large property, a longer run time is non-negotiable.
Next, consider the cutting swath. This is the width of the path the trimmer cuts with each pass. A wider swath means you can cover more ground faster, which is fantastic for big, open areas. A narrower swath gives you more precision, which is perfect for navigating tight spaces around flower beds, fences, and trees. For most people, a medium swath offers a good balance of speed and control.
Don’t forget about the power transfer system. You have two main choices: direct-drive and bump-feed. Direct-drive systems connect the motor directly to the head, providing instant power and responsiveness. Bump-feed systems are more common and involve tapping the head on the ground to release more line. I find direct-drive to be more efficient, but bump-feed is perfectly adequate for most residential tasks and is often more affordable.
Finally, think about the entire tool ecosystem. If you already own a brand’s power tools, like a drill or a blower, it often makes sense to stick with that brand for your cordless string trimmer. This way, you can share batteries between tools, which saves you money and the hassle of managing different chargers. It’s a small detail that makes a big difference in your overall tool experience. By weighing these factors—power, swath, feed system, and battery compatibility—you can confidently select a trimmer that will make yard work feel less like a chore.
Frequently Asked Questions
How long does the battery typically last on a cordless string trimmer?
Battery life varies a lot depending on the model and how you use it. A smaller, lower-voltage battery might last 15-20 minutes, which is fine for a tiny yard. More powerful models with larger batteries can easily run for 45 minutes to over an hour on a single charge. If you have a bigger job, look for a model that comes with two batteries or has a quick charger so you can always have a fresh one ready to go.
Can a cordless trimmer handle thick weeds and grass?
Yes, many modern cordless trimmers are surprisingly powerful. The higher-voltage models (36V and above) have no trouble with thick, overgrown grass and even light brush. The key is to use the correct line thickness for the job. A thicker, more durable trimmer line will power through tough vegetation much better than a thin, standard line. For the very best cordless string trimmers for your yard, you want one with enough power and the right line to match your typical workload.
What is the difference between a brushless and a brushed motor?
This is a great question. A brushed motor uses physical brushes to transfer power, which creates friction, heat, and eventually, wear. A brushless motor is more advanced; it uses an electronic controller for power transfer. The benefits of brushless motors are significant: they are more efficient, which means longer run times from the same battery, they generate less heat, and they last much longer. While brushless models are usually more expensive, the investment is often worth it for their durability and performance.
Are cordless string trimmers as powerful as gas-powered ones?
For most typical home use, a high-quality cordless trimmer is absolutely comparable to a gas model. They start instantly with the pull of a trigger, are much quieter, and require virtually no maintenance—no oil, no spark plugs, no messy fuel mixing. While the absolute top-end gas trimmers might still have an edge for commercial, all-day use, the power gap has narrowed dramatically. For maintaining a residential yard, you will likely not notice a difference in performance, and you will definitely appreciate the convenience.
How do I advance the line on my trimmer?
Most residential trimmers use a “bump-feed” system. It’s simple: while the trimmer is running at a good speed, you gently tap the plastic head on a flat, clear spot on the ground. This action releases a small amount of new line. You don’t need to slam it; a light tap is all it takes. Some higher-end models have an automatic feed that senses when the line is short and advances it for you, which is a nice convenience feature.
