Braun Series 9 PRO All‑in‑One AIO 9550 electric trimmer, shaver & clipper — waterproof, AutoSense, PrecisionLock (with Gillette La

The Braun All-in-One Series 9 PRO AIO 9550 is a rechargeable, fully waterproof men's grooming system that trims, clips, shaves and details face, hair and body with AutoSense power and precision length control.

This compact kit combines a high-performance Series 9 PRO trimmer with precision attachments and a Gillette Labs razor to handle full-body grooming from dense beards to fine edges. Engineered in Germany, the AIO 9550 uses AutoSense to adapt motor power to hair thickness, a Lifetime Ultra Sharp ProBlade for clean strokes, and PrecisionLock settings for fine-tuned length control—so one tool covers beard, hair, nose, ears and body without swapping multiple devices.

How does the Series 9 PRO tackle thick or fast-growing beards?

The trimmer reads hair density and raises output automatically so cutting stays consistent even through dense patches. PowerBoost mode adds short-term extra torque for stubborn areas, reducing tugging and the need for repeated passes.

• AutoSense technology adjusts motor power to beard thickness.
• PowerBoost for extra cutting force on dense hair.
• Lifetime Ultra Sharp ProBlade for one-pass efficiency.
• Detachable precision trimmer for finishing lines and mustaches.

What length options and precision controls are available?

PrecisionLock and the integrated control wheel let you choose from more than 50 settings in 0.25 mm steps for micro-adjustments or broader 0.5 mm ranges. A simple switch locks the head for accurate shaping around tricky edges like sideburns and neckline.

• PrecisionLock with 50+ lengths in 0.25 mm increments.
• Control wheel for fast, intuitive adjustments.
• Precision ProTrimmer attachment for detailed edging.
• Head lock feature for stable trimming on contours.

Can I use the AIO 9550 in the shower or with shaving cream?

Yes—the device is fully waterproof and safe for wet or dry use. You can pair it with foam, gel or use it in the shower; the sealed design simplifies rinsing and hygiene after each session.

• 100% waterproof body for wet/dry grooming.
• Compatible with foam and gel for smoother shaves.
• Easy rinse under running water for cleaning.
• Cordless Li-ion battery supports extended runtime.

How reliable is the battery and build quality for travel?

The long-lasting Li-ion battery is built to supply extended cordless runtime, and the trimmer’s titanium-coated parts resist corrosion for durability. Its robust German engineering and travel-friendly cordless design make it suitable for frequent trips and daily use alike.

• Li-ion battery with up to long runtime for multiple sessions.
• Titanium-coated components for corrosion resistance.
• Cordless convenience for travel and on-the-go grooming.
• Durable construction engineered in Germany.

Who is this for: The Braun All-in-One Series 9 PRO AIO 9550 is ideal for men who want one durable, high-performance tool for complete grooming—those with dense beards needing extra power, anyone who values precise length control, travelers who prefer cordless reliability, and people who want a waterproof device usable with shaving products in or out of the shower. It suits barbers at home and individuals seeking an all-purpose kit to trim, clip, shave and detail face, hair and body with professional-level results.
