The powerful, versatile Panasonic Beard Trimmer ER-GB40-S for men can easily be used cordless anytime, anywhere or plugged it into an AC outlet for longer use. The durable, super-sharp blades in this powerful beard and mustache trimmer system are precision-honed to an acute 45° angle to create the optimal cutting edge for quick, efficient maintenance of beards, hair and mustaches. A quick-adjust trimmer dial is located on the sure-grip, ergonomic men's cordless trimmer handle to provide 19 precision settings — from 1mm to 10mm — for the exact length you want for smooth, precise trimming, sculpting, detailing and cutting. This Panasonic hair and beard trimmer for men is also wet/dry convenient. When you’re in a hurry, the ER-GB40-S waterproof beard trimmer delivers a quick, even dry trim over the sink or on-the-go. And, because this Panasonic trimmer is fully immersible in water, it also performs just as effectively when used in the shower. Clean up is quick and simple. The Panasonic ER-GB40 beard and mustache trimmer cleans under running water with easy-open water drain for thorough cleansing and maintenance, and a handy cleaning brush is included for on-the-spot hair clipper blade cleaning. The included, high-efficiency AC charging stand keeps your mustache and beard battery charged and ready. An indicator lamp glows red while the Panasonic ER-GB40-S trimmer is charging. And for grooming away from home, both the compact beard and mustache trimmer and stand fit easily into any men's grooming kit, bag or luggage. Power source AC 120V.
