Worx WG163 vs BLACK+DECKER LST300: Which Cordless System Fits?

Start with the compatible battery system you already use: PowerShare points toward WG163; 20V MAX POWERCONNECT points toward LST300. If either system works for you, choose Worx when you want its additional Command Feed button. Both document automatic feeding.

The buying question

Which compatible battery system do you want to use, and is automatic feed enough or do you want an additional feed button?

WG163 joins Worx PowerShare and adds Command Feed alongside automatic advance. LST300 joins BLACK+DECKER POWERCONNECT and documents automatic spool feeding without bumping.

Quick verdict

Choose Worx WG163 if

  • You want WG163 to join compatible PowerShare equipment and value the extra feed control.

When the recommendation changes
  • Your existing packs and charger are not listed as compatible with the chosen trimmer.
  • An additional line-feed control matters enough to change your preferred battery system.

The differences that matter

Existing Cordless Battery System

Worx WG163

Uses the Worx PowerShare system. Check the designated battery and charger compatibility for WG163.[1, 2]

BLACK+DECKER LST300

Uses the BLACK+DECKER 20V MAX POWERCONNECT system. Check the designated battery and charger compatibility for LST300.[3, 4]

What this changes: An existing compatible setup can settle the choice before you compare feed controls. A shared 20V label is not evidence that packs or chargers can be interchanged between brands.[1, 2, 3, 4]

The better fit depends on your priorities

Documented Line Feed Controls

Worx WG163

Automatically advances line when starting from rest and also provides Command Feed. The motor stops while the button is held and restarts on release.[2]

BLACK+DECKER LST300

Its AFS spool automatically feeds line as needed. The instructions prohibit bumping the head to advance line.[3, 4]

What this changes: Worx fits a buyer who specifically wants the additional control; LST300 fits one satisfied with its documented automatic routine. Neither description establishes fewer jams, less line use or uninterrupted cutting.[2, 3, 4]

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Compare exact kits after checking compatibility. Battery quantities shown across Worx variants are not a reliable basis for a bundle-value conclusion.

There is not enough price history here to recommend buying now or waiting.

Limitations

  • No hands-on cutting, runtime, noise, vibration, line-consumption or reliability comparison was performed. The shared voltage label is not a performance ranking.
  • Worx: keep the guard fitted, use the specified line and designated charging equipment, and remove the battery before adjustments, head maintenance or troubleshooting. Its instructions prohibit rain and wet-location use.
  • BLACK+DECKER: fit the guard, use only the specified 0.065-inch round nylon line and remove the battery before adjustments, line replacement or cleaning. Its instructions prohibit rain and wet-location use. Follow its eye, hearing and bystander precautions.
  • The selected LST300 configuration lists a battery and charger. Worx’s current page presents several kit variants; its displayed battery quantity differs from the selected listing and model table. Verify the exact offer rather than transferring another variant’s contents.
  • The LST300 guide is dated September 2014. Its charger-placement and charging-time information differ from the current product page, so neither is used here as setup guidance. Check the instructions supplied with the actual charger. The retained Worx booklet explicitly includes WG163 but has no clear printed issue date.

Questions shoppers ask

Is WG163 manual-feed only?

No. Automatic advance and Command Feed are both documented. The button pauses the motor until released; it does not mean the trimmer keeps cutting while the button is held.

Can I use any battery marked 20V?

No such compatibility is established. Match the actual pack and charger to the chosen model’s approved equipment, rather than matching voltage labels or using a cross-brand adapter.

Should I choose LST300 just because I want automatic feed?

Automatic feeding alone does not separate these models. Choose based on compatible battery equipment and whether Worx’s additional control matters to you.
