Wahl Stainless Steel Beard Trimmer — Slate Model 9864, 3.5‑Hour Lithium Ion Kit with T‑Blade & Nose/Ear Heads

Wahl's Stainless Steel Lithium Ion 2.0+ Slate Beard Trimmer (Model 9864) is an all-in-one rechargeable grooming kit with four heads, ten guide combs, and up to 3.5 hours of runtime for precision beard, face, nose and ear care.

This premium cordless trimmer combines a slate-finish stainless-steel housing with self-sharpening precision blades and upgraded Lithium Ion 2.0+ battery technology. Made in the USA, the kit bundles a wide T-blade, a precision detailer, a rotary nose/ear trimmer, a dual-foil shaver head, and multiple guide combs so you can shape, trim, detail and finish facial and body hair at home or on the go.

How will this trimmer handle daily beard shaping and touch-ups?

The wide T-blade and included guide combs let you quickly reduce length, define edges, and maintain stubble or fuller beards. Self-sharpening blades stay effective over time for consistent results with minimal tugging.

• Wide T-blade for beard, mustache, and body touch-ups
• Ten guide combs: eight fixed (1/16"–1/2") and two adjustable (2mm–21mm)
• Self-sharpening stainless-steel blades for durable cutting

Can I use it for nose, ear and close shaves?

Yes — the kit separates tasks with purpose-built heads. The rotary nose/ear trimmer is rinseable for hygiene (remove before rinsing), while the dual-foil shaver provides an ultra-close finish on the face and neck.

• Rotary ear and nose head detaches and rinses for cleanliness
• Dual-foil shaver head yields a smooth finish after trimming
• Precision detailer head for edges and small design work

How long does the battery last and is it travel-ready?

Wahl's Lithium Ion 2.0+ battery delivers up to 3.5 hours of continuous use on a single full charge and holds charge well during storage. Worldwide voltage compatibility makes it suitable for travel; a travel lock prevents accidental activation in transit.

• Up to 3.5 hours runtime per full charge
• Minimal memory loss — long storage times between charges
• Worldwide voltage and travel lock for safe international use

What maintenance does the trimmer require to stay in top condition?

Keep blades clean and lightly oiled for best performance; use the included cleaning brush and rinse removable blades after detaching. Avoid immersing the trimmer body in water and remove the charger when storing the unit.

• Remove and rinse blades; dry fully before reattaching
• Use included brush and apply blade oil at least every other trim
• Do not store with charger plugged in; avoid wetting the trimmer body
