Norelco All-in-One 3000 Series 13-in-1 Cordless Trimmer MG3939/50 — 8 Lengths, Self-Sharpening Metal Blades

The Norelco Philips All‑in‑One 3000 Series MG3939/50 is a 13‑piece cordless trimmer that trims beards, hair, nose and ear hair with self‑sharpening metal blades and up to 60 minutes of runtime.

This versatile grooming kit combines durable metal cutters, multiple combs and a detail blade to let you shape stubble, sculpt a beard or tidy up a haircut at home — all with rounded blade tips designed for comfortable skin contact. The set includes eight adjustable length options, a narrow detail trimmer, nose‑hair attachment and rinseable parts for straightforward upkeep. A USB‑A cable powers charging on the go and the battery indicator keeps you informed of remaining charge.

How does this trimmer adapt to different beard and hair styles?

The kit provides range and control through interchangeable heads and a wide span of length settings. Switch between combs to go from a close 0.5 mm stubble to longer, maintained lengths up to 16 mm for fuller beards or quick haircuts.

• 13 included attachments for beard, head, nose and detailing
• 8 length settings covering 0.5–16 mm for gradual or dramatic adjustments
• Click‑on combs for fast, repeatable styling

What makes the blades suitable for regular use?

The blades are made from full metal and engineered to stay sharp without routine oiling, helping maintain crisp cutting performance over time. Rounded tips on each blade reduce friction and irritation, letting you trim closer with less risk of nicking sensitive areas.

• Self‑sharpening metal cutters preserve edge quality
• Rounded blade tips for gentler skin contact and smoother passes
• Removable heads that rinse clean for hygiene and longevity

How long does the battery last and how do you charge it?

The rechargeable battery supplies up to 60 minutes of cordless run time per full charge, ample for several grooming sessions. A USB‑A cable is supplied so you can charge from a laptop, power bank or wall adapter (adapter not included), and an indicator light shows charging status and battery level.

• Up to 60 minutes of cordless use from a full charge
• USB‑A charging cable included — adapter sold separately
• Battery indicator light for convenient charge monitoring

How easy is maintenance and everyday handling?

The trimmer is designed for simple cleaning and comfortable control. Removable combs and blade assemblies rinse under water, while an ergonomic handle makes long or detailed sessions less fatiguing.

• Washable blades and combs speed up post‑use cleaning
• Ergonomic grip improves maneuverability for precise shaping
• Durable attachments resist bending and frequent swapping

It suits those who value durable metal blades, multiple length options and portable USB charging — ideal for home use, travel or quick touchups between professional barber visits.
