Wahl Stainless Steel Cordless USB Beard Trimmer — Black Diamond Forever Blade, Waterproof, 3.5‑Hour Runtime

The Wahl Pro Series Stainless Steel Cordless USB Beard Trimmer is a waterproof, long‑running grooming tool with a Black Diamond coated Forever Blade that delivers exceptionally close, smooth trims.

Designed for everyday use and travel, this cordless Wahl trimmer combines a durable stainless‑steel body with a soft silicone grip for secure handling during wet or dry grooming. Its advanced lithium‑ion power system provides extended runtime and very low self‑discharge in storage, while the near‑zero gap blade geometry and hard carbon coating focus on delivering a cooler, closer cut. The kit includes multiple guide combs and USB charging for flexible styling and convenience.

How does this trimmer deliver a closer, smoother cut?

The trimmer uses a Forever Blade finished with a Black Diamond Hard Carbon coating that resists heat and gliding friction. The near‑zero gap blade setup moves hair extremely close to the cutting edge for precision shaping and refined finishes.

• Black Diamond coating for reduced drag and cooler cutting
• Near‑zero gap blade design for up to four times closer cutting versus older Wahl blades
• Precision metal blade construction for consistent edge retention

What power and charging features should I expect for travel and daily use?

This model uses an updated Lithium‑Ion 2.0+ battery delivering about 3.5 hours of continuous operation per full charge, ideal for multiple trims between charges. A USB cable is included so you can recharge from common power banks, laptop ports, or wall adapters while traveling.

• Approximately 3.5 hours runtime on a single full charge
• USB charging for compatibility with modern chargers and power banks
• Low self‑discharge so it stays charged during storage

Can I use and clean this trimmer in wet conditions?

Yes—the unit is fully waterproof, which means you can trim in the shower or rinse the trimmer directly under running water for easy cleanup. The waterproof design simplifies maintenance and helps keep the blade area free of loose hair.

• Fully waterproof housing for wet/dry grooming
• Blade and body rinseable under running water for quick cleaning
• Silicone grip helps maintain control when hands are wet

What styling options come with the kit for different beard lengths?

The package includes seven guide combs that let you switch between short detailed trims and longer stubble styles. There are six T‑blade guide combs for close cutting and a 10‑position adjustable comb for intermediate lengths, giving precise length control across a wide range.

• Six T‑blade guide combs covering 1/16” to 1/2” (very short lengths)
• One 10‑position adjustable guide comb ranging from 2 mm to 11 mm
• Quick comb changes for fast style transitions
