Best Cordless String Trimmers Buyer Guide
There are factors that you should take into consideration before buying a cordless string trimmer.
Below are the most important factors to ensure that you get the best cordless string trimmer that fits your specific needs.
Runtime/ Charge Time
Since cordless trimmers ideally come with a single battery, it is essential you know its runtime.
Go for a trimmer with a longer-lasting runtime to avoid the inconveniences of having to recharge the battery after a few minutes of use.
The higher the AH of a battery, the longer the run time after a single charge.
Some of the best string trimmers have a run time of up to 60 minutes.
Charging time, on the other hand, is also another factor to consider.
A battery should not take too long to charge since it minimizes the trimmer’s downtime.
For a string trimmer to be useful, it should be capable of cutting overgrown and tough weeds.
The more the workloads, the more powerful trimmer you need.
Nickel-cadmium batteries have less power and require frequent charges, while lithium batteries will give you longer runtime and better performance.
You can determine how powerful a battery is by checking its voltage; the more the voltage, the more powerful it is.
Comfort and Design
Your choice of string trimmer should be ergonomic, offering you a comfortable time during operation.
A curved shaft string trimmer is the best in terms of ease of use and ergonomically, while a straight one is recommended for only small and tight lawns.
You can also go for a 2-in-1 trimmer since it gives you the freedom to interchange both designs.
Check whether the trimmer is maneuverable enough to reach tight areas like under bushes or flowers
Most solid 40 Volts plus cordless trimmers range from 175 to 250 dollars.
The cost of a cordless string trimmer mainly depends on its battery and the construction materials.
Battery determines the performance of the product while the construction determines the durability.
If you on a tight budget, go for string trimmers with a low AH but note that it will come with its drawbacks.
However, the battery recharging and replacements may be too frequent, leading to more maintenance costs.
Choose a trimmer that will give you reliable service for a more extended period.
A good string trimmer should be light and strong at the same time due to the kind of task it performs.
Battery type largely determines the trimmer’s weight; lithium-ion batteries are lighter than Nickel-Cadmium batteries.
Trim width is the total width covered by the trimmer with a single pass.
Different trimmers have varying trim width ranging from 12 -15 inches.
For a small yard, go for the 12 inches, and for the larger yards, go for 13- 15 inches.
