LiTHELi 20V 12-inch Cordless String Trimmer & Edger — 2×2.0Ah Batteries, Auto-Feed, Telescoping Shaft

The LiTHELi 20V 12-inch cordless string trimmer/edger is a lightweight battery-powered weed eater that converts between trimming and edging, includes two 2.0Ah batteries, an auto-feed spool, and a fast charger for uninterrupted yard work.

Designed for homeowners who want a maneuverable electric alternative to gas models, this 12" trimmer delivers a 12-inch cutting swath with a single 0.065" line and a peak motor speed of up to 6,550 RPM. At about 4.5 pounds it’s easy to handle, while the telescopic shaft and adjustable auxiliary handle let you tailor reach and comfort without tools. The package includes two rechargeable batteries, a quick charger, six replacement spool lines, a flower guard and trimmer guard, and a safety lock to prevent accidental starts.

How easy is the LiTHELi trimmer to carry and control?

Portability is a primary design goal: the unit weighs roughly 4.5 pounds and balances for one-handed maneuvering when needed. Comfort features reduce fatigue during extended edging or trimming sessions, and tool-free adjustments make setup straightforward.

• Lightweight 4.5 lb profile for less strain
• Telescoping shaft adjusts from 36" to 47" without tools
• Rubber covered auxiliary handle secures at any angle
• Ergonomic layout for longer use

Can it handle both trimming and edging tasks?

Yes — the head converts between a trimmer and an edger, so you can trim grass or create clean borders without swapping tools. The single-line spool auto-feeds 0.065" line and cuts a 12" swath, while four head-angle positions make it effective on slopes and uneven ground.

• 2-in-1 trimmer/edger head for multi-purpose yard work
• Auto-feed spool keeps line at the right length
• 12" cutting path covers more area per pass
• Four angle settings for various terrains

How long will the batteries run and how quickly do they recharge?

The kit includes two 2.0Ah lithium-ion batteries so you can swap packs for extended runtime. Batteries deliver crisp RPMs for efficient cutting, and the fast charger reduces downtime between tasks.

• Two 2.0Ah Li-ion batteries included for continuous work
• Fast charger shortens recharge intervals
• Maximum speed up to 6,550 RPM for consistent cutting power
• Battery and charger covered by a one-year warranty

What safety and protective features are included?

Safety features focus on preventing accidental starts and protecting plants and the operator. A lock-off button near the trigger prevents unintended activation, while included guards minimize stray debris and shield delicate landscaping.

• Lock-off safety switch located by the trigger
• Flower guard and trimmer guard for plant protection
• Balanced design reduces risk of slips during use
• Three-year warranty on the tool for long-term support

Who this is for: the LiTHELi 20V 12" cordless trimmer/edger suits homeowners, renters, and small-property caretakers who need a lightweight, low-maintenance alternative to gas-powered string trimmers. It’s ideal if you value easy handling, quick setup, and straightforward maintenance—especially for edging driveways, tidying lawn borders, and recurring trimming around flower beds and walkways. If you frequently work in tight spaces, prefer quieter electric tools, or want the convenience of spare batteries and a fast charger, this kit covers those needs while offering warranty protection for both tool and power components.
