XIELAOBAN 21V Cordless String Trimmer — Wheeled 4-Blade Edger with Dual 2.0Ah Batteries and 650W Motor

This battery-powered tool combines portability and control: a 650W motor powered by two 21V 2000mAh lithium batteries delivers enough runtime for small- to medium-sized yards while a wheeled base and adjustable handle let you trim and edge with minimal bending. Safety features include a dual-start security button and battery temperature/overload protection. The trimmer’s adjustable head flips from 0° to 90° for edging, and the handle extends from 34.7 to 48 inches so users of different heights can work comfortably at lower effort.

How long will one charge last while trimming a small yard?

Run time depends on load and cutting conditions, but the two 21V 2000mAh batteries give 60–120 minutes of work on a single charge under typical residential use. Lighter trimming and intermittent use push runtime to the higher end, while continuous heavy cutting decreases it.

• Battery type: two 21V, 2000mAh lithium packs
• Estimated runtime: roughly 60–120 minutes
• Charging time: about 2–4 hours
• Built-in overload and temperature protection for safer charging and operation

What adjustments let me trim edges and low areas without straining?

The trimmer head rotates from 0° to 90° so you can switch easily between upright trimming and vertical edging. The telescoping handle extends from 34.7 to 48 inches, and the overall tool weighs only about 3.2 pounds, reducing strain for users of differing heights and mobility.

• Head angle range: 0°–90° for trimming versus edging
• Handle length: 88–122 cm (34.7–48 inches) for customized reach
• Lightweight construction: approximately 3.2 pounds for easy maneuvering
• Wheeled base for stable guided edging along paths and lawns

What cutting system and safety features come with this trimmer?

The tool uses a four-blade cutter paired with a 650W high-power motor to handle grass and light branches. For safety, there’s a two-step start—pressing a security button plus the on/off switch—and the battery includes overload and temperature protections to reduce risk during heavy use.

• Cutting: four replaceable blades suitable for thick grass and light stalks
• Motor: 650W high-power unit for improved cutting performance
• Start safety: dual control start (safety button + switch)
• Battery safeguards: thermal and overload protection built into battery pack

What should I know about maintenance and first-time use?

Before the first session, fully charge the battery to ensure optimal performance. After each use remove the battery to prevent accidental power-on and charge/stow batteries in a cool, dry place; periodically inspect blades and fasteners for wear or looseness.

• First use: fully charge batteries before operation
• Post-use: remove battery pack to isolate power
• Routine checks: tighten fasteners and inspect blades for damage
• Safety tip: keep bystanders at a safe distance while operating

Who is this for: The XIELAOBAN 21V Cordless String Trimmer is suited to homeowners with small to medium lawns who want a compact, low-fatigue trimming and edging solution. It’s especially helpful for users seeking a lightweight tool with adjustable ergonomics—such as seniors, those with limited lifting strength, or anyone who prefers a wheeled guide to produce straight edges—while still offering the power and battery safety features needed for routine yard maintenance.
