Best Electric Weed Eaters – Buying Guide

You can find hundreds of electric weed eaters in the market these days. However, the process of checking and buying is the same for every model. Below, we have included a buying guide that would help you in separating good electric weed eaters from the ones that are not suitable for you. Here are the most important factors that you need to consider while buying an electric weed eater. 

String Trimmer Design and Layout

The layout and design of your string trimmer are crucial because you’ll use the machine for a long period. A badly designed trimmer makes the user tired quickly and results in awkward handling. The overall experience depends heavily on the motor placement, overall weight, and shaft length. When it comes to shaft length, most models come with adjustable lengths.

Trimmer shafts comes in two design types: straight and curved. Straight shafts are more suitable for taller people and those who need a little distance between the handle and the ground. As for the curved shaft, it’s more comfortable, lightweight, and reaches challenging spots like under the bush. You must find out which type is ideal for you. 

String Features

The string of a weed eater is among its most important parts. You must check if your weed eater can be easily restringed and has nice line-feed abilities. Additionally, check its cutting width too. A broad width clears a large area in a single sweep. 

However, a narrow one is practical for small, tight spaces. Moreover, look for an even mix of single and dual-feed lines. A dual-line offers better cutting power, but a single-line head is sufficient for most gardens.


Of course, the power source of an electric weed eater is the electricity. Weed eaters with more powerful engines consume more electricity. This is why power ratings are important.

Corded weed eaters tend to be more powerful, offering a standard of 120 volts with different current levels. If you want more power to remove robust weed or grass, get a corded model. Since they’re corded, they have a short range, which is why they’re better suited for small to mid-sized gardens. For small yards, 1 to 4 amp rating is enough.

However, for large yards, choose a weed eater with more than 5 amp rating. If you don’t have tougher weeds, choose a cordless electric weed eater. Needless to say, these machines have an increased mobility. Therefore, they’re more suitable for large yards.


When you buy a weed eater, make sure it’s powerful enough with a strong battery. However, you must not forget to consider the battery charge time. This time depends on the power rating and battery type, which results in different charging times. People usually go for batteries and chargers that result in shorter charging times to save their time.


In electric weed eaters, weight is a crucial element. The overall weight of the machine affects its portability. You’ll be using the machine for longer periods, so it should be extremely lightweight for you. Fortunately, most electric weed eaters aren’t too heavy. 

Wrapping It Up

Now that you have all the necessary information, we hope that you won’t find it hard to get the best electric weed eater. You buy a weed eater only once in a few years, so make sure you pick a durable product. We have done the hard part, and now it’s up to you to identify your requirements and choose the best electric weed eater for your garden.
