Customer Questions & Answers

does it come with a battery charger? and can you leave it charging until you need to use it w/o dmg to the battery?

Asked by: kauaiboy
Instructions say yes. Charger blinks until it's ready to use. A great trimmer and edger. One charge lasts long enough for a normal-sized yard/house/walkways.

Auto feed

How is the auto feed on this? I currently have an older Black & Decker Grass Hog with an auto feed spool and it is horrible. No matter how careful I am to reload the spool, it never auto feeds properly or it jams. So I dread using it and I'm leary of getting another trimmer with an auto feed spool.
Asked by: JCobes
Yes it is autofeed. I bet your problem is NOT using cartridges. Worth the extra money; comes in packs of three; can get them from Amazon. This is our second "grass hog" and I'd gladly buy another! One charge on the new one just purchased in April lasts long enough to trim 2000 sqft house, fence, and edge sidewalk. Cartridges last a very long time in my opinion. We use three in 12 months.

how long does it take for the battery to recharge?

Asked by: Red
24 hours for full charge; charger has blinking light while it's charging, so that you'll know when it's ready.

Customer Reviews

20-Volt Max Lithium-Ion 2-Speed String Trimmer is rated 4.3 out of 5 by 103.
Rated 4 out of 5 by from Solid for my Yard I hated dealing with my corded trimmer, and I don't have a big enough yard to deal with a gas trimmer, so I gave this rechargeable B&D a chance. I have a small yard, and it works well. For most trimming I use the low setting to save battery life, and it does just fine around the rocks, poles, posts, etc. I only switch to high for edging my sidewalk. I can get probably 40-45 minutes out of a charge, so I can't trim the yard and edge the sidewalk. But I can do one or the other. The auto-feed is great and becomes a time-saver; I'm over dealing with bump-feed. I waited a couple months to review this, to myself time to assess it completely. I'm happy with it.

I'm a gurl but in good shape, not pint size but small ..... and I'm a home owner with a lot of ambition. I bought a home with a gorgeous yard. And, I want to keep it that way. This little edger is amazing! So satisfied with it that I'm taking time to say that "this little edger is amazing". I don't have a large yard so it's the perfect size. And, I already have a Black and Decker drill with the same battery .... so bam, I have enough battery to more than get the job done. Let me add that I've spent hundreds of dollars on edgers and grooming tools. This is the best yet .... let the BEST lawn competition begin. :)

Rated 5 out of 5 by from As expected I bought this because I wanted mobility and don't have a lot of areas that weed eating is needed. I was not disappointed as I was able to edge my entire front yard and weed eat my back yard. Great product for the price.

I have a fairly good sized front yard and a large back yard and this trimmer does a good job at allowing me to attack all the edging in a fair amount of time. With the edging and trimming around the trees and tall plants it goes through a full battery with it on the max speed(roughly 45-50 minutes) . It does take me using a second battery for 15-20 minutes to wrap up the rest of the job. I really like i can use the same battery for my Drill and Driver and a couple of the other tools. If you get this get a second battery , you'll want to have one standing by. All in all its a very good product.

Rated 5 out of 5 by from Received this for Father's Day Already had the hedge clippers that use the same battery (love those too). This thing works great. Got a 1/2 acre lawn and use up a battery and a half usually. Has more power than you would think. I use the edger wheel a lot for the driveway, walkways, and front curb - its a nice feature. Two seconds to flip from edger wheel back to normal trimming. This trimmer will cut into the dirt nicely to give you an edge. Not quite as powerful as a gas trimmer, but the ease of use / low maintenance factor of this thing is more valuable to me than having the strongest trimmer on the block. Would definitely recommend.

Rated 5 out of 5 by from Amazing little trimmer! Did my research and read reviews. I didn't believe that this little thing would work that well being only one string (versus the two string gas powered hunk of junk I had before that I thought did a good job) but I am amazed at how well it it trims and edges. The only thing I will say against it is the battery life and re-charging time but I knew that going in. As long as you don't have a huge area to do or are not in a rush to do it then it will work just fine. I'm going to buy a second battery and a better charger and then it will be perfect!

Rated 5 out of 5 by from GREAT! I bought this trimmer for my son so he can start learning how to take care of a lawn. It's a great trimmer if you are looking for something lightweight and easy to use . It's power is good for it being one string in oppose to other two string edgers. If you're looking into have a good electric edger and not spending more this one is for you. I also recommend to use number 1 power . There's a option of choosing 1 or 2 , 2 is of course powerful but drains the battery. I just cut my edges with the 2 and my battery drained just when I was about done . With the 1 set on I never drained my battery .

Rated 5 out of 5 by from Excellent cordless choice This Black & Decker LST522 trimmer / edger is a nice cordless trimmer with excellent features. The trimmer can be rotated with the twist of the wrist so that it performs as an edger; it comes with an edger wheel attached. The trimmer speed can be set at 1 for longer battery usage or 2 for more power. The length of the shaft can also be adjusted with a simple twist. I am 6’ 1” tall and fully extended is best for me. The D shaped handle angle can be adjusted with just the push of a button. The cutting head is the single string type. It uses the Model No. AF-100 replacement spool filled with .065 inch (1.65 mm) round nylon mono-filament line. It comes with a full spool already installed. Assembly is very easy and only consisted of simply pushing the plastic guard into a slot and securing with a single screw. A single 20-Volt 2.5AH Lithium-Ion battery is included. The battery charger that is included is very compact and it takes about 3-5 hours to recharge the battery. With a total weight of less than 8 pounds the trimmer is light weight but it still feels sturdy. It is ideal for trimming borders and edging sidewalks as well as drive ways. I get about 30-55 minutes of moderate to light trimming from one charge. If you have been using a gas or plug in type trimmer you will love the convenience and comfort of this versatile cordless trimmer. Based on my experience I recommend it as a good choice for the smaller suburban lawn. I have provided photos and a short demo video, I hope they help.
