​If you are looking for the right weed eater to maintain your lawn, the Black & Decker NST2118 might be just what you’re looking for. But before you go ahead and purchase this trimmer, make sure that it has everything you need.

​What are the important aspects of theBlack & Decker NST2118 Cordless Electric GrassHog?


This trimmer is a type of electric trimmer that is not limited by a cord. Being cordless, it runs using two 18-Volt NiCad batteries. This is good for people who don’t want their movement to be limited by a cord as they can freely traverse larger areas through this.

Cordless trimmers are suitable for owners with large yards and lawns that couldn’t afford to drag a long cord behind them.

Other types of trimmers are gas and electric-corded trimmers. Gas trimmers are for heavier use as the fuel powers up the engine more while corded trimmers are suitable for trimming a small area, for post-mowing maintenance.


For a battery operated trimmer with a decent cutting path and power, the Black & Decker NST2118 is lighter compared to its peers. This trimmer only weighs 6.4 pounds and can be easily wielded and controlled.

As for the size of the trimmer itself, it is considered to be in the medium category, but still packs a punch with dealing with stalky weeds and grass.


The Black & Decker NST2118’s exclusive PowerDrive transmission ables the motor to deliver more power into the cutting string so you’ll be able to finish a large area faster, giving your more time to relax and enjoy outdoors with your family. The batteries also enable users to reach more areas away from power supply to make sure that every inch of your lawn is trimmed and manicured.

This trimmer also features a Groom'N'Edge head that can be rotated 180-degrees for quick switches between cutting and edging tasks.

There is also the so-called Automatic Feed Spool (AFS) system, known to be a main feature in Black & Decker trimmers, which uses centrifugal force to dispense more line whenever you need it for added predictability and dependability.

Ease of Use:

This trimmer easily starts with the pull of a trigger; you don’t have to trouble yourself with several pulls to start it, unlike gas trimmers. Although considered to be in mid-weight in the world of trimmers, the Black & Decker NST2118 is very easy to handle and carry with your for long periods of trimming.

The best part for comfort is its telescoping pole that enables you to adjust it to your preferred height. This gives your back a huge favor, considering the weight you have to carry. Being cordless, you also won’t be limited or bothered by a cord behind you. Meaning, you’ll be able to reach more areas without added worry.


This trimmer doesn’t come with any attachments that will make it function more than a trimmer and edger, unlike other products/brands out there. This shouldn’t be considered as a deal breaker, however, because the Black & Decker is still capable of properly doing its job.

The package comes with an external battery charger that plugs easily onto a household outlet and is Energy Star qualified for energy efficiency.

Help and Support:

This trimmer is backed by a two-year warranty. It comes with a helpful manual for helping you put together your machine, as well as help and support via online and telephone.

​What other things should you know about the Black & Decker NST2118 Cordless Electric GrassHog?

Putting it together is fast and easy; all you need to do is follow the instructions in the manual that comes with it. Afterwards, starting it can be done with just one pull.

Since this is a medium sized trimmer, you might have trouble with hard stalks and tall grass as well as large clumps of weed. Be careful as it might damage the cutting string. Make sure to take cutting one step at a time.

The battery holds a good charge, although some owners have complained about the lack of efficiency of their batteries.

This might be associated with a poor one, and you can get your machine easily swapped if this is the case. The charge should hold up at least with an hour. Charging it can be a pain though, as it takes about nine hours.

​The Verdict

If you aren’t planning to use your trimmer for long periods of time, then the cordless Black & Decker may fill your needs. It can be brought all the to far locations without power source and effectively cut and edge grass.

However, if you’re searching for a trimmer with more runtime without having to stop to charge for an entire day, you can choose to get a corded one or a gas-fueled one. Each has its own pros and cons, but it heavily depends on usage and needs. Take time to read about each one before purchasing.
