Panasonic ER-GB40-S Cordless Beard Trimmer with 19-Position Dial & 45° Blades | Wet & Dry

Meet the Panasonic ER-GB40-S, a versatile beard and mustache trimmer designed to adapt to your daily grooming routine. This model delivers cordless freedom with up to 50 minutes of runtime on a rechargeable NiMH battery and can be used plugged in for longer sessions when you’re near an outlet. The blades are precision-honed to a 45° edge, promoting clean, efficient cuts that help maintain shape with fewer passes. The result is a dependable tool that supports quick touch-ups or more deliberate sculpting, whether you’re at home, in the gym locker room, or on the road.

Length customization is centered on comfort and control. The quick-adjust dial offers 19 precision settings, ranging from 1 mm to 10 mm, so you can dial in the exact length you want for a stubble, beard, or mustache look. The ergonomic, rubberized grip keeps the trimmer steady in your hand, reducing fatigue during longer grooming sessions. For added flexibility, the trimmer supports wet or dry use, letting you combine grooming with your routine or use it on dry hair when you’re in a rush. The unit is fully immersible in water, making cleaning straightforward and efficient after use.
