Cordless vs. Corded Weed Eater
Electric weed eaters come in two main categories: corded electric weed eaters and cordless electric weed eaters.
#1. Cordless Electric Weed Eaters
Also known as battery weed eaters, this type of weed eaters run on battery power. The size of the battery varies from one model to another.
18-volt cordless weed eaters are ideal for lawns measuring up to 1/3 acre while 24-volt cordless weed eaters are perfect for lawns up to 2/3 acre. Those above 36 volts come in handy for lawns measuring from roughly 2/3 to about an acre.
Cordless weed eaters have one main advantage over the corded electric weed eaters. They give you complete freedom from cords, a feature that makes them extremely portable. That said, they can be used just about anywhere as long as you have charged them ahead of time.
Pros
- Can be used virtually anywhere
- Can be used for light to medium trimming tasks
- Quiet operation
- More economical to operate than corded weed eaters
Cons
- Usage limited by battery run time
- More expensive compared to corded weed eaters
- Heavier than corded weed eaters
#2. Corded Electric Weed Eaters
Corded weed eaters come with a power cord that needs plugging into the main power line. That means your usage of these babies is limited by the length of the cord. These weed eaters come with different motor sizes rated in amps. Generally, the higher the amp, the more powerful the motor.
Corded electric weed eaters are specially designed for small lawns measuring up to 1/3 acre. This type of weed eater generally comes lighter than cordless weed eaters since there is no additional weight of batteries.
Pros
- Lighter in weight compared to cordless weed eaters
- Unlimited run time and consistent power
- Little or no maintenance
- Less expensive than cordless weed eaters
Cons
- Poor coverage limited by the length of cord
- Must deal with the frustration of cord getting in your way
Advantage of Using Battery Powered Weed Eater
Battery-powered weed eaters or cordless weed eaters have many advantages that give them an upper hand over most gas-powered and corded weed eaters. Let’s look in detail at the advantages that make a battery-powered weed eater a more convenient choice.
- Lighter: Though every model comes quite different, battery-powered weed eaters are generally lighter compared to gas-powered weed eaters. It’s not uncommon to find battery weed eaters that come at half the weight of the gas models.
- The reason for their lightweight construction comes from the fact that they sport lightweight aluminum shafts and smaller heads. They also lack an internal combustion engine that contributes more to its handy lightweight construction. Generally, battery weed eaters weigh less than 13 pounds.
- Quieter: Weed eaters can be quite noisy, especially the gas-powered models. Some may require protective hearing aid in order to operate comfortably. Battery weed eaters come quieter … to the extent that you will probably not need a hearing protector to operate the unit. You can get some models that are as quiet as 85 dB.
- No emission: With battery-powered weed eaters, you get the convenience of zero-emission, a feature that makes them more eco-friendly. In short, they have a very limited carbon footprint compared to gas units, especially those with 2-cycle engines. In this day and age, conscientious homeowners will do everything they can to reduce carbon emissions in order to help protect the environment.
- Unlimited mobility: Battery units can be used just about anywhere. Unlike corded electric units, there’s no limitation to the range of usage.

Disadvantages of Using Battery Powered Weed Eater
Battery-powered weed eaters are great, but they are not always the best tool for every yard working purpose. There have been many times where I have forgotten to charge the battery and my weed eater is dead. There’s nothing I can do to speed up the process, I just need to plug in the battery and wait until the next day.
Here are some more things to think about.
- Battery Chargers Die: Even if you buy a backup battery, sometimes that’s not enough. I’ve had more than one battery charger die on me and those things are not easy or inexpensive to replace. Often times, I put in a few more bucks just to get a new weed eater. A gas weed eater can last you much longer before it dies since it doesn’t rely on electronics that can be finicky.
- Even though gas weed eaters can be heavier, there is a good reason for that bulk. They can generally be sturdier machines than what you find with battery-powered ones.
- The quieter noise not only comes from the lack of an engine but also because it has less power than most gas weed eaters. If you’re whacking a lot of weeds, you are going to miss the power of a gas or corded weed eater.
- Expensive backups: As mentioned earlier, you might have to buy an extra battery AND an extra battery charger to have as a backup in case things go wrong. Compared to a gas weed eater where you just need to have an extra can of gas lying around, the cost of this can add up.
