The two main types of string trimmers are gas string trimmers and electric string trimmers (and a few electric string trimmer sub-types). There are advantages and disadvantages to both with some of these features compensated for by finding the best string trimmer line.
You might find that the best corded electric trimmers for your backyard are more environmentally friendly than a gas string trimmer. However, when you need more power for professional use you might want to check out the Husqvarna 4 stroke trimmer, instead.
Which Are Better Gas or Electric String Trimmers?
It’s a good idea to look at the specific differences between gas string trimmers and electric string trimmers to really understand which kind of string trimmer works best for your backyard.
To help you further compare gas-powered trimmers and electric string trimmers, we have put together a guide that will ultimately help you tackle all of those backyard chores.
String Trimmer with the Most Power
Gas string trimmers are more powerful than electric string trimmers. Being gas-powered, the engine is more capable of powering through weeds and thickly overgrown lawns.
Though some electric string trimmers have decent power, none of them can match the strength of one that has a gas engine. If you need to trim rocky lawns, a landscape with different levels or large commercial areas, then one with a gas-powered engine is the better choice.
Best String Trimmer for Covering Large vs Small Areas
How much power a string trimmer has is closely related to how suitable it is for small or large areas. You don’t need that much power for an average sized backyard lawn but you will need more power for a commercial space like a golf course or resort hotel. 
Corded electric string trimmers are great for the average backyard. They may have less power than a gas trimmer but they hold enough power for a small area.
Corded electric string trimmers are more affordable, make less noise and are more environmentally friendly than one running on fossil fuels. This makes them the best gardening tool option for personal use.
For large areas, look into a gas-powered string trimmer. Being cordless, you do not need to stay close to a power supply which lets you cover more ground.
Cordless electric string trimmers are not as well suited for covering large areas as you might think. The battery on this type of tool has a limited amount of run time so you might need a second battery on hand to be able to cover a large area.
Which String Trimmer is the Easiest to Use?
The ease of use of a string trimmer depends on the model but you can make a few generalizations on the user-friendliness of the different types.
A gas string trimmer requires the most maintenance so it is the least user-friendly. It requires oil changes, refueling, and general engine maintenance to keep working properly.
A corded string trimmer is the most user-friendly because it is a plug-and-go system. However, the cord does limit your movement which might make it more difficult to use for certain backyards.
Cordless electric string trimmers also require little maintenance besides replacing the battery. Plus, as they are cordless it is easier to maneuver them around uneven lawns and rocky patches.
Another factor to consider for the ease of use is how safe it is. A gas trimmer is the least safe option because of the release of fumes and the use of flammable fuel.
A cordless electric trimmer is the safest to use because you have the least chance of a short circuit. You also don’t risk a damaged cord like with their corded counterparts.
Most Environmentally Friendly Trimmer
A gas-powered string trimmer is obviously not environmentally friendly since it uses fossil fuels as its source of power. These machines are noisy as well, so there is also the factor of noise pollution.
Arguably, corded electric string trimmers are the most environmentally friendly type of string trimmer. This is especially true if you are using an outlet that is fed by a renewable energy source like wind energy or thermal energy.
Since cordless electric trimmers do not produce any fumes, they are also more environmentally friendly than a gas string trimmer. However, it is difficult to dispose of batteries in an environmentally conscious way. Use rechargeable batteries whenever you can for a more environmentally friendly upgrade.
Conclusion of Gas vs Electric String Trimmers
There is no straightforward answer on which type of string trimmer is the best. It really depends on whether you are using this gardening tool for personal use or are looking for a commercial grade option that you can use for a small business or heavy duty use.
Think about the area that you need to cover and the type of vegetation. Gas string trimmers may be the best choice for professionals but the electric string trimmers also have a lot of advantages to consider.
