WORX vs BLACK+DECKER string trimmer: what is the main difference?
The WG163 gives you more edging guidance and a second battery; the LST300 advances line automatically. Both models have a 12-inch cutting width and switch between trimming and edging.
The WORX head tilts 90 degrees for sloped ground and hard-to-reach spots. Rubberized wheels guide the edger, while an adjustable spacer guard helps protect plants and lawn features.
The BLACK+DECKER uses an Automatic Feed Spool, so it advances line without bumping. Its handle and height positions adjust for comfort and control.

Which one is easier to guide and carry?
The WORX WG163 is slightly lighter by the listed weights, while both are compact 12-inch tools. The 0.2-pound difference is small enough that handle fit and balance may matter more to you.
The WG163 is 5.5 pounds, and the LST300 is 5.7 pounds. Those figures don't tell you how each feels in your hands, so an in-store hold can help if comfort is a deciding factor.
The WORX offers a tilting head and wheels to guide edging. The BLACK+DECKER offers adjustable handle and height positions, which let you change the setup to suit your stance.

How do the line-feed systems compare?
Choose the WORX push-button feed if you want to decide when line advances; choose BLACK+DECKER automatic feed if you prefer the tool to feed line as needed. Neither setup removes the need to keep suitable line on hand.
The WG163's Command Feed spool advances line at the push of a button. Its line diameter is 0.065 inches.
The LST300's Automatic Feed Spool feeds line when needed, with no bumping. Its 12-inch swath matches the WORX WG163's 12-inch cutting diameter.

What comes in each battery kit?
The WG163 includes 2 batteries, while the LST300 includes 1. Both are 20V kits, but their batteries belong to different brand tool systems.
WORX says its Power Share batteries work across its 20V and 40V tools, outdoor power and lifestyle products. BLACK+DECKER's 20V MAX Powerconnect battery works with its 20V MAX Powerconnect tools.
The WG163 kit includes 2 batteries and a charger. The LST300 kit includes 1 battery and a wall-mountable charging base.
If you already own compatible tools from either brand, that battery family may be the deciding factor. Our string trimmer buying guide explains how power, weight and line fit into a full comparison.
When does the WORX WG183 make sense?
Consider the WORX WG183 if you want a 13-inch cutting width and a WORX battery kit. It has a dual-exit cutting head, automatic feed and 2 included batteries.
The WG183 weighs 6.4 pounds, about 0.7 pounds more than the WG163. Its adjustable auxiliary handle offers another way to set up the grip.
This model is a trimmer, not the same 2-in-1 trimmer and edger format as the other two. Pick it for its wider cut and trimming features, and compare the 40V vs 20V trimmer guide if battery voltage is central to your choice.
Which WORX vs BLACK+DECKER string trimmer should you choose?
Pick the WORX WG163 for edging guidance and 2 included batteries; pick the BLACK+DECKER LST300 for automatic line feed and an adjustable setup. Choose the WG183 if a 13-inch cut matters more than a listed 2-in-1 edger.
Before choosing, check the line system, battery compatibility and the way you'll use the tool around borders. For more brand comparisons, see EGO vs Greenworks string trimmers.
