Powerful Rechargeable Li-Ion battery.

The Braun Series 5 integrates a PowerDrive feature for high speed cutting even on dense hair. With 20% more motor power than previous generations, the motor supplies sufficient torque on every terrain. The powerful rechargeable Li-Ion battery is fully charged in 1 hour – for up to 45 minutes of cordless shaving. A 5 minute quick shave gives you sufficient charge for one cordless shave. The SmartPlug has an automatic worldwide voltage adjustment (100V-240V), for optimum convenience – at home or away. As a wet & dry shaver, the Series 5 5040s is for cordless use only.
