Wahl Stainless Steel Cordless Beard Trimmer 9818A — Lithium‑Ion, 3.5‑Hour Runtime, Multi‑Head

This compact rechargeable trimmer combines a T‑blade, a rotary ear & nose head, and a detail trimmer to cover trimming, edging, and small‑area touchups. Built with self‑sharpening precision blades and a long‑running lithium‑ion battery, the kit is designed to handle a wide range of facial hair lengths and styles at home or while traveling.

How long will the battery last and how quickly does it recharge?

The Wahl 9818A uses lithium‑ion technology to deliver extended runtime and fast charging. A full charge yields up to 3.5 hours of continuous use, and a one‑hour charge restores full power. There’s also a one‑minute quick charge that provides about three minutes of runtime for emergency touchups.

• Full runtime: up to 3.5 hours
• Full charge time: 1 hour
• Quick charge: 1 minute = ~3 minutes use
• Dual voltage: works on 110V–220V for travel

What cutting lengths and styling options does it provide?

This kit offers a wide range of cutting lengths via eight fixed T‑blade combs and a 10‑position adjustable guide comb. The guides let you go from very short stubble to longer beard lengths while the precision heads allow crisp borders and tight detailing around mustache, goatee, and sideburns.

• T‑blade fixed comb sizes: 1/16" to 1/2" for close to medium lengths
• Adjustable guide comb: 10 positions from 2mm to 11mm
• Detail head: fine edge work for lines and shaping
• Rotary personal trimmer: safe nose and ear hair removal

Which attachments are included and what are their best uses?

The kit is purposely versatile: the primary T‑blade trims general beard and mustache hair, the rotary head removes nose and ear hair hygienically, and the detail trimmer tackles tight areas and design work. All heads are quick to swap, making it simple to switch tasks without multiple tools.

• T‑Blade: general beard shaping, mustache trimming, and touchups
• Rotary trimmer: safe removal of nose and ear hair
• Detail trimmer: precision lines, eyebrows, and small patches
• Included accessories: storage pouch, charger, cleaning brush, blade oil

The blades feature self‑sharpening technology so performance stays consistent over time. Wahl tests cutting performance at the factory; any fibers seen on the blades are from hygienic testing and wipe away easily.

Who is this for? The Wahl Stainless Steel Lithium‑Ion Cordless Beard Trimmer 9818A is aimed at men who want a single portable kit for everything from everyday stubble maintenance to precise styling and nose/ear cleanup. It suits travelers, at‑home groomers, and anyone seeking a durable, pro‑grade trimmer with long battery life and a range of length options.
