Wahl Aqua Blade Rechargeable Wet/Dry Beard Trimmer 9899-100 — Waterproof Lithium‑Ion with Interchangeable Heads

The Wahl Aqua Blade® Rechargeable Wet/Dry Beard Trimmer is an all-in-one lithium-ion grooming kit built for precise edging, wet or dry use, and travel-ready battery life.

Engineered by Wahl, a century-old pro brand, this Model 9899-100 brings interchangeable heads, a sealed waterproof body, and a powerful lithium-ion motor together in one compact trimmer. It combines an angled ultra-close blade with multiple attachments—T-blade, rotary detailer, and precision head—plus guide combs and travel accessories so you can trim facial hair, moustaches, sideburns, and body hair with control. The sealed aqua blade construction lets you rinse the unit after use and operate safely in the shower, while the lithium-ion pack delivers long runtime and quick-charge convenience for busy mornings or trips.

How does the Aqua Blade handle wet and dry grooming?

The Aqua Blade design is sealed for showerproof operation and rinsing, so you can trim with foam or in the sink without worrying about damage. Self-sharpening precision blades and low-noise operation maintain cutting performance in both wet and dry conditions.

• Waterproof housing allows safe rinse and shower use
• Self-sharpening blades retain edge and cut smoothly wet or dry
• Low noise motor for discreet bathroom or overnight trimming

What attachments and length options are included?

This kit ships with three interchangeable trimming heads and a set of guide combs to cover everything from detailed edge work to longer beard styling. Heads snap on and off for fast switching between face detailing, ear/nose trimming, and full facial or body grooming.

• Extreme Precision T-blade for crisp edges and close shaving
• Rotary head and detail trimmer for shaping mustaches and sideburns
• Eight guide combs (1/16"–1/2") plus a 10-position adjustable comb for varied lengths

How long does the battery last and what about charging?

The rechargeable lithium-ion battery is tuned for extended runtime and long-term reliability—up to two hours of continuous use on a full charge. A quick-charge function provides minutes of trimming from a short charge, and worldwide voltage makes this trimmer suitable for travel.

• Up to 2 hours runtime per full charge
• Quick 3-minute charge yields approximately 5 minutes of use
• Compatible with 110–220V for international travel

How do I maintain performance and blade life?

Routine cleaning and light lubrication keep the precision blades cutting well—rinse after wet use and dry thoroughly when used outside the bathroom. Wahl recommends charging the battery fully at least every six months to preserve battery health and storage life.

• Rinse blades under fresh water after use; towel dry exterior when used outside shower
• Apply included blade oil periodically to reduce wear and prolong sharpness
• Charge fully every six months if stored to maintain battery health
