Customer Questions & Answers

Is a battery charger included with the purchase? or do you just plug it in and unplug it for use?

Just have seen this item on line.
Asked by: Timbo
Battery is removed to charge. The model from HD is LST400 which has 1 battery, the LST420 has 2 batteries. Last check I did was HD does not carry the 420.

How long does the battery take to recharge?

Asked by: Bandmom
Out of the box, the initial charge took about 10 hours. The next time I had to charge it, it took about 8 hours. I get about 1 hour of run-time before needing to recharge the battery.

Can this trimmer be reloaded with bulk trimmer line instead of having to buy Black and Decker specific replacement cartridges?

Asked by: dataway
Yes, but not recommended. Hard to get the auto feed system to work correctly if you do not get tension correct.

Customer Reviews

20-Volt Lithium-Ion Straight Shaft Electric Cordless String Trimmer is rated 4.3 out of 5 by 203.
Rated 5 out of 5 by from better than what I was expecting Did not want to spend a lot, was a little worried about other reviews complaining about battery life being short but bought it anyway since we don't have a real big yard. I have used it once a week for four weeks without recharging. love the auto line feed. I thought the guide wheel and 90 degree rotate for edging was a lame gimmick but found I really love that feature the most. it wouldn't hurt to have more power but for the price I got more than I was expecting and quite pleased with this purchase. I give it five stars based on what I got for the price.

Rated 5 out of 5 by from string trimmer It's very easy to use and easy to put together. It does not use a lot of string like two of the other black and decker combo edger and blower 20 volt and 40 volt. I love this this edger. This is my second one. The only problem is it doesn't last for a long time.

Rated 5 out of 5 by from Love Black & Decker 20 V Max* Trimmer/Edger LST 400 The price was lower than other places that I researched online. It does the job with two speeds. The wheel for edging worked perfectly. Black &Decker products are easy to assemble, easy to understand and durable.

Rated 5 out of 5 by from Solid weed eater I had a gas weed eater that was heavy and hard to start. In purchasing this product it is fast, easy to handle, and light. Also, runs on a battery for one hour. I recommend this product.

Rated 3 out of 5 by from Light duty This is fine for small light work, but doesn't deliver the power to trim thick grass or weeds easily. Requires multiple passes to adequately trim thicker weeds and grass alone fence lines.

Rated 5 out of 5 by from Powerful, Light weight Excellent tool. Really does the job. Rotating head for edging is a big plus; guide wheel is a big help. I still haven't figured out how the automatic line feed knows when to kick in, but it does. Better than a bump feed. Battery has never run down on me yet. Recharges quick; probably won't ever use my gas trimmer again.

Rated 4 out of 5 by from Battery needed to be replaced I love this edger. After 4 months of ownership, the battery failed. Had to be replaced through the warranty process. Took a couple of weeks to locate my receipt. Then the battery was on back order, which tells me they are having production problems with this new 20v battery. Took 2 more weeks to reroute a battery from a different distribution site to me. So after 6 weeks I have it working again. I just love it. Just wished the battery was more reliable. But the next time it croaks, I'll have the receipt ready and if it is backordered, I and the repair center will know to find one somewhere else in the country and get it to me in a more timely manner.
