The buying question
Can you manage an outdoor extension cord, and do you want a dedicated line-feed button alongside automatic feed?
Sun Joe uses outlet power and a trigger stop/restart feed routine. Worx uses a removable battery and adds Command Feed while retaining start-up automatic feed.
Quick verdict
Choose Sun Joe TRJ13STE if
- You can provide the required outdoor cord and outlet arrangement.
- You are satisfied with the documented trigger stop/restart feed routine.
Choose Worx WG163 if
- You want to avoid a trailing power cord and can plan for charging.
- You want the dedicated Command Feed control as well as automatic feed.
When the recommendation changes
- The work area cannot be reached with a suitable cord arrangement.
- A dedicated feed button matters enough to influence your choice.
- The conditions are wet; neither manual permits use in rain.
The differences that matter
Corded Or Removable Battery Work Area
Sun Joe TRJ13STE
A 120 V corded trimmer. Its instructions require GFCI protection and a suitable outdoor extension cord, with the cord kept clear of the cutting area.[1]
What this changes: Sun Joe fits a work area with a suitable outlet and a manageable cord route. Worx fits a buyer who wants to carry battery power around the work area and can plan for charging.[1, 2, 3]
Line Advancement Controls
Sun Joe TRJ13STE
The documented automatic-feed routine uses a trigger stop and restart. The manual warns against bumping the head to feed line.[1]
Worx WG163
Provides automatic feed when starting from rest, plus a Command Feed button. During Command Feed, the motor stops while the button is held and restarts when it is released.[3]
What this changes: Choose Sun Joe if its documented trigger routine meets your needs. Choose Worx if you want the additional dedicated feed control. The button does not establish uninterrupted cutting or less line consumption.[1, 3]
Best for your routine
A buyer with a suitable cord route who wants the documented trigger-feed routine
Best fit: Sun Joe TRJ13STE
Based on listed features, not comparative testing.
TRJ13STE supplies that corded setup. Check the manual’s outlet, extension-cord and dry-condition requirements.
A buyer who wants removable-battery power and an extra line-feed control
Best fit: Worx WG163
Based on listed features, not comparative testing.
WG163 combines a removable pack with Command Feed and start-up automatic feed. The button does not mean the motor runs continuously during feeding.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
Judge any current price difference against your cord route, charging routine and use of the additional feed button. Verify the exact WG163 package; the manufacturer page presents multiple kit variants.
There is not enough price history here to recommend buying now or waiting.
Limitations
- Neither trimmer was tested hands-on. This comparison does not rank cutting performance, weight, vibration, runtime, coverage, line consumption or ease of use.
- The Sun Joe instructions are the 2019 MR4 edition. The Worx booklet explicitly includes WG163 and several variants; its issue date is not clearly stated. The current multi-variant product page and the selected retail kit show different battery quantities, so quantity and bundle value are not compared.
- Follow the complete instructions for guards, protective equipment, cord routing, charging and maintenance. A feed control is not permission to touch the cutting head while connected to power.
Questions shoppers ask
Does WG163 lack automatic feed because it has a button?
No. Its manual describes automatic feed when starting from rest as well as Command Feed. Holding the button stops the motor; releasing it restarts the motor.
Should I bump the Sun Joe head to advance line?
No. Its manual warns that bumping can damage the trimmer and specifies a trigger stop/restart routine. Allow the motor to stop completely and follow the manual’s pause before restarting.
Can I use either trimmer in wet grass or rain?
Both manuals prohibit rain and damp or wet-location use. Sun Joe additionally specifies dry grass and weeds and prohibits operation below 50°F (10°C).
