In this Black & Decker NST2118 review, we find a cordless string trimmer which is often referred to as the GrassHog NST2118 trimmer. It comes complete with a pair of 18 volt batteries to provide the user with twice as much running & decker nst2118 review

This might not be of that much importance to you, if you don’t have a lot of grass that needs to be trimmed but for those with a fair area to be tended, it means the difference of finishing the job in one go. One battery can be on charge, ready if needed when the first one peters out.

Of course being cordless allows the Black & Decker NST2118 trimmer to be used anywhere in the yard without relying on electric power from the mains outlet. Making a more neat and tidy finish to the grassed areas where the lawnmower has been unable to reach.

Changing the trimmer head from the flat general position to the lawn edging cut, can be done using Black and Decker’s Groom’N’Edge head feature. This allows the head to rotate 180 degrees to do the edging work.

The B&D NST2118 cordless string trimmer also removes the need for bumping the head in order to feed more new line from the spool.

Centrifugal force is used to create an automatic feed spool, making adding new string that bit more easy.

(Quick note: There are other versions which will give more power if tough weeds need to be tackled or larger areas need to be cleared. The next stage up with a stronger battery than the NST2118, would be the Black & Decker LST136 with the 36-Volt battery.)

I have noticed that the B and D NST2118 is only available as a factory reconditioned model.  The reconditioned version number is NST2118R, see the link below for more information on that model.

Will the NST2118 be available again is anyone’s guess and will depend on B&D, but I suspect that it will not.

Video of a Cordless Line Trimmer In Action

I have added a video of a similiar string trimmer in action to give some idea how these machines perform.  Although this is not the Black & Decker NST2118 model, it looks very similar with a lot of the same features.

Could be an earlier model as the model number looks to be earlier, something I need to check out! Hope it helps.

I have two 3/4 acre yards to cut/maintain (not at the same time) and i seriously doubt anyone is getting 20-30 minutes of continues run time. I feel that I am proficient at trimming/edging,no back and forth swinging, pull the trigger, drop and go. That being said I have light/moderate grass and was surprised how much I got done in 13 minutes. A 40ftx140ft perimeter for the house, 3 trees, 30ft driveway (one side), 20ftx24ft work shop and a 40ft fence line (both sides). with the 2nd battery I was able to cut my front ditch (3ftx160ft) with thick grass(10 minute run time). No edging, so that left the 3rd battery for touch up.

I bought this trimmer because I had a Black & Decker that operated like this one, but it was not cordless. I love the Idea of not having a cord.The saleman told me that the batteries would last thirty to forty five minutes. I did what the instrustions said and charged the batteries and did just light weedeating,down the driveway and started down the side of the house. It wasn’t long the battery was dead. I changed the battery. I looked at my watch and continued weedeating. The Battery only lasted ten minutes.

It took me 5 minutes overall to unpack, assemble the trimmer, and another 8 hours to charge the battery before I can use it. It is lightweight, but comes with surprising power. The string feeds continuously and did an excellent job of trimming. Edging take a little to get used to, but I can already see how convenient it is. There are 2 batteries that come with the trimmer that can be used with other 18v B&D tool. This trimmer really hooked me into using cordless tool. My next purchase will be a 18v blower
