Review: Very light and effective trimmer - I’m very well designed trimmer that cuts through grass and weeds very easily. The battery lasts about 45 minutes. It’s fairly light and easy to use. I think it’s also a pretty good value. Review: LST522 Your Money's Worth/5th year now - 5th year now and I am alive, and still extremely happy with trimmer. I have bumped my stars to 5. All that I wrote before still applies, I am older man with respiratory problems and I need all the help I can get maintaining the yard in the hot summer heat. This trimmer and my new small ride-on mower are my new two best friends. 1. No extension cords. What a wonderful freedom. (Circle a bush twice then go straight to the next !) 2. Lightweight. The shaft and work head rotate for sidewalk edge trimming and that's it. No head tilt or similar extras. I figure that's what keeps it lightweight and in the cost range it's in. 3. I bought this trimmer for trimming grass around places a mower can't get, weeds before they reach 3 feet tall and trimming sidewalk edges. It does that just fine in less than half the time it took with my old corded whacker. 4.Battery- I have busy yards with playthings, a garden, bushes, trees and flowerbeds with borders and more. They are fair size yards and it uses about a battery and a half. Unless you have small yard I suggest you buy an extra battery also 5. Dinky Charger. Yes it comes with a slow dinky charger but once again I believe considering the price range warrants a no star reduction. After purchase I found out I could use my Porter Cable 20v fast charger after a small simple battery alternation. It's a convenient, but I believe with the two batteries I could have made the slow charger work. 6. The wheel and sidewalk trimmer. Cool idea I think, just pull shaft collar up, turn shaft around then roll along sidewalk edge cutting grass hanging over the sidewalk. ( No, not made for trench digging like gas edgers :-) 7. Line out works as advertised. My string nightmares might be over. The filled cartridge it came with worked like a charm. Line out automatically when needed and no jams. I bought 2 extra refills later. There is an art to refilling your own and my lack of patience in the past has cost me grief. 8. Two speed. If you're thinking about it you'll probably will go with high speed, however the other day after finishing one yard I then noticed I had it on low. If your needs and thinking parallel mine somewhat I think you will find this a great buy. ## Features - Automatic Line Advancement: The AFS system automatically dispenses trimmer line as you work, delivering uninterrupted performance with your Electric Weed Wacker - Extended Battery Capacity: The LBXR2520 battery offers 66% more runtime compared to standard models, ensuring your lawn trimmer keeps going through larger projects - Dual Speed Control: Easily switch between higher power for tough areas or longer runtime for extended jobs, optimizing results with this versatile lawn edger - Enhanced Cutting Power: PowerDrive Transmission boosts torque at the string, giving your grass edger the strength to tackle dense growth - Effortless Conversion: Quickly transform the tool from trimming to wheeled edging for clean lines along sidewalks and driveways - Adjustable Comfort: Enjoy customizable height and handle settings with a premium soft grip for improved control and comfort - Premium Handle Grip: Micro-texture handle design provides a secure, comfortable grip during use - 20V MAX System Compatibility:* Part of the 20V MAX* system, offering flexible power for a wide range of tasks - Included Components: Comes with LST522 20V MAX* cordless trimmer/edger, LBXR2520 20V MAX* extended runtime lithium battery, charger, AFS spool, and guard - 2-Year limited warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B019Z72FM4 | | Best Sellers Rank | #4,930 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #13 in String Trimmers | | Brand | BLACK+DECKER | | Brand Name | BLACK+DECKER | | Color | Multi | | Customer Reviews | 4.5 out of 5 stars 6,372 Reviews | | Cutting Width | 12 Inches | | Cutting width | 12 Inches | | Global Trade Identification Number | 00885911450447 | | Included Components | 20V MAX 2 SPEED STRING TRIMMER | | Item Dimensions L x W | 41.33"L x 9.25"W | | Item Type Name | 20V MAX 2 SPEED STRING TRIMMER | | Item Weight | 5.7 Pounds | | Manufacturer | Black & Decker Outdoor | | Manufacturer Part Number | LST522 | | Manufacturer Warranty Description | 2 year limited warranty | | Model Number | LST522 | | Number of Batteries | 1 Lithium Ion batteries required.

That is what I am doing. I bought the Black & Decker 20 volt Drill and Flashlight combo a while back. The combo only came with one battery. Then I bought the trimmer with two 20 volt batteries. They interchange beautifly. I actually called B&D before I purchased the trimmer to ask this question. Good luck. **Q: Can you reload your own line or do you have to buy the preloaded spools?** A: I have always bought the bulk pack and loaded it myself. Just make sure it's .065 ROUND line! (That's what's specified in the manual.) Wind it snugly, and in the right direction, and you should have no problem. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very light and effective trimmer *by S***C on March 12, 2026* I’m very well designed trimmer that cuts through grass and weeds very easily.

Easy to handle. Bought for my wife to be able to use. I had another brand however too heavy and complicated for her to use. Replacement of nylon cords very easy and easy to order them on Amazon. Battery life is good for 20 V. Recommend getting a fast charge battery station. Cons The switch to operate went bad. Hard to open the unit to find the issue. It appeared the small limit switch not making contact. Was able to adjust to get it working again however the problem reoccured. To much trouble to replace, bought another as it was just out of 2 years warranty , (2 years & 6 months). Bought the same unit. To much trouble to try to get a warranty replacement. ## Frequently Bought Together - BLACK+DECKER 20V MAX Cordless String Trimmer and Edger with Spool, Battery and Charger Included, 2 Speed, 12 Inch (LST522) - 10 Pack Weed Eater String Compatible with Black+Decker, AF-100 0.065" Weed Wacker String Refill 240ft Automatic Feed String Trimmer Replacement Spool Line for Black&Decker(8 Spool+2 Cap+2 Spring) - YWTESCH 10 Pack AF-100 Replacement Spool Line for Black+Decker - 0.065" Weed Eater String Trimmer Line Spool, 30ft Autofeed Weed Wacker Spool Refill for Black+Decker(8 Spool,2 Cap,2 Spring) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/25438411-black-decker-20v-max-12-inch-weed-eater-cordless-string](https://www.desertcart.at/products/25438411-black-decker-20v-max-12-inch-weed-eater-cordless-string) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-22*
