Why do they call it "cordless" when it uses string

This question is from 40-Volt Electric Cordless Straight Shaft String Trimmer

March 4, 2016
I have had horrible luck with string trimmers in the past. Hoping to find something that uses blades instead of that annoying string. Why are these products called "cordless" when some kind of cord is used to knock down weeds? The category "cordess" raised my hopes, which are now dashed. Every product description I opened uses string, which is a variant of "cord."

Answer: 
Some trimmers, such as this one, has a replaceable head, meaning you can take off the head that uses string, and replace it with a head that uses plastic or metal blades. They call those brush cutter heads. That is what I am going to do.

Cord in this case refers to electrical cord that powers the trimmer, not the plastic string that trims or cuts grass/weed. I'd be eager to get a stringless trimmer myself. Even better if it uses air rather than blades.

Due to the higher capacity battery this model will probably be heavier than older models your Dad is used to using. I found my arm was getting a tired pretty quick compared to the older model B&D I had intended to replace this unit with.
I found the battery run time far shorter than stated on the box. I was completely out of power in less 30 minutes.

It's vey light compared to a gas trimmer. With the battery in place it's also well balanced. Not knowing your fathers physical abilities I would recommend visiting a Home Depot and letting him get a feel for it. As for the battery, it has never let me down. I use mine weekly for basic clean up after mowing. A half hour of use on medium speed and it has never pooped out. I was very skeptical about buying this. But after years of battling the mix gas trimmers not starting, running erratic, throwing projectiles at 100mph at me and everything around me, I gave this a try. 2 years of loyal service. Couldn't be happier. Keep in mind this is a maintenance trimmer. You can't go mow down a field of 4ft. weeds. But to keep a maintained yard maintained, this is must have. Read Less

I think it is lightweight, but I used to use a 4 cycle gas trimmer. It is hard to know if it will be good for your dad without knowing whst "lightweight" means to him. I have a small townhouse property of 6000 SF so the battery life is fine 4 me. It has different power settings so you can dial it down to lower power to & the battery will last longer if you are just trimming grass.

Rated 4.6 out of 5 by 887 reviewers.
Rated 5.0 out of 5.0 by Great Value Great value for the price. It's lightweight and very powerful. The only downfall is the battery life. It runs out before I finish the entire yard (even when I use it on the lowest setting). June 30, 2016
Rated 5.0 out of 5.0 by Perfect for the Woman who likes Yard Work! This is perfect for me. I had the 18V and it would take a long time to edge my very long driveway and side walk. With this one, the variable power lets you muscle through with ease and speed. Best of all it is not too heavy like most gas powered and you don't throw your shoulder out cranking it up. Push in the button and flick the switch and away you go. Plenty of power to get the job done. Love my Black & decker yard tools. One small piece of advice. Go ahead and buy extra spools of line. They don't give you much to begin with, and you can get carried away trimming with all the ease. July 19, 2016
Rated 5.0 out of 5.0 by Awesome! I was hesitant buying a battery operated line trimmer as I always have had gas ones. But, this performs very well. I like the variable speed setting and use it mostly on 3 or 4. Don't have to have the hassle of gas and mixing and...you know the rest. Battery charges very fast. But, I can get my entire yard done without running out, so charging is not an issue. I was a little annoyed that I couldn't just walk into a Home Depot and buy one. It was available only online. Funny thing though, I ordered it on a Wednesday and it came the very next day with regular shipping chosen! So, I guess not that annoying. June 28, 2016
Rated 5.0 out of 5.0 by Awesome! I've been using this for 3+ years now and I can't say enough good things about this. Only today did I finally run out of string for the trimmer and am going to get more later tonight. The performance has been reliable and the battery life has not been a problem. I'm able to complete the trimming of my lawn with a half battery left. I have two batteries so I just switch them out on the charger as I use one and replace it with the other. It's a very efficient system and for me that's very important. I love it! July 20, 2016
Rated 5.0 out of 5.0 by Great! Wow! Technology has come long way. I used to seldom trim my yard. Because pulling out the 100' extension cord was such a hassle. I did not want a gas powered trimmer, so I just lived with what I had. This thing is a game changer. No cord, no gas, fast and simple. Holey moley, I trimmed the entire yard; front and back in about 10 minutes. The dial that saves battery power is useless to me, because it has to be turned to full power. The fact that I no longer have to tap the trimmer on the ground to feed more line, and I don't have to plan my route to not tangle an extension cord is alone a winner. BUY ONE!!! You'll love it! June 26, 2016
Rated 4.0 out of 5.0 by Good product thus far Downsizing from a 2-stroke gas powered trimmer to a battery operated trimmer takes some getting use to. However, this light compact 40V trimmer does the job around my small yard, yet I was surprised when I found it to be only a single line trimmer. Not having a double line will limit the ability to cut thicker stem plants/weeds. I run around my .25 acre yard in 15 minutes or so and have yet to charge my battery in the 3-times I've used it since the original charge up. The noticeable difference in using this Black & Decker 40V trimmer is the ability to grab and go - no more filling a gas tank and yanking on a pull cord several times then waiting for a motor to warm up. June 28, 2016
Rated 5.0 out of 5.0 by Great trimmer! We bought this to use on a bare swath of land along the back of our yard, between the lawn and a stand of trees. We live in a maintenance-free community, so don't own a lawn mower. We hoped a string trimmer would be enough to keep the weeds down/prevent them from encroaching on other landscaping. We've only used it once so far, but it worked beautifully. We ran it constantly for 30 minutes on one battery charge, which was enough time for us to cut down all the weeds in an approximately 300 square foot area. Love the self-feeding of the string, not having to bend down and pull more out or bump on the ground. We also purchased an additional battery, but think we'll return it since one charge should always be enough to keep our weeds down. The price was excellent, especially for the quality of this tool. July 20, 2016
Rated 4.0 out of 5.0 by Sure beats a gas trimmer........for me! I haven't had long enough to make a subjective review but my initial impression is very positive. I love the light weight and the charge lasts for quite a long time. It does take quite a while to recharge the battery so I would recommend purchasing a second battery if possible so your project doesn't come to a halt before you finish. I use the trimmer for knocking down weeds on a half acre lot and the unit seems up to the task. Plenty of power for all but the real heavy stemmed weeds and I keep my unit on the lowest setting which works fine for the dry grass and tall weeds I have on my property. I would recommend this product at this point. Still don't know how long the cutting string will last and of course only used it twice so I'm hoping it proves to be a long term reliable unit. Beats the heck out of a gas trimmer that's for sure. July 19, 2016
