Foil shaver Braun Series 7 71-S4200cs Black AutoSense Battery

The Braun Series 7 71-S4200cs Black AutoSense Battery foil shaver is a wet & dry electric shaver with AutoSense technology that adapts motor power to beard density for consistent cutting performance. It uses a foil shaving system combined with an integrated pop-up trimmer for precision on sideburns and mustache areas. The unit is powered by a rechargeable Lithium‑Ion battery and comes with a base station for automatic cleaning and charging to simplify maintenance and storage. The black finish provides a modern, low-profile appearance suitable for everyday grooming.

Advantages

AutoSense technology continuously adjusts cutting power according to beard thickness to maintain an even shave without repeated passes. The foil system offers close contact with the skin for a smooth finish while the built-in trimmer handles detailed work. A rechargeable Lithium‑Ion battery delivers longer run time and stable performance throughout the charge cycle. The included base station performs automated cleaning and charging, reducing manual maintenance and preserving hygiene. The shaver is washable and rated for wet & dry use, enabling use with water, foam or gel and allowing easy rinsing after use.

How to use

Charge the shaver in the base station before first use until the battery indicator shows a full charge. For a dry shave, glide the foil gently over clean, dry skin using light, circular motions and avoid pressing the foil tightly to the skin. For a wet shave, apply foam or gel and shave under running water or in the shower, then rinse the foil frequently. Use the pop-up trimmer for shaping sideburns, mustache lines and hard-to-reach areas. After shaving, place the shaver in the base station for automatic cleaning and charging according to the manufacturer’s instructions.

Recommendations

To maintain optimal cutting performance, rinse the shaver head after each use and run the cleaning program in the base station regularly. Replace the shaving head or foils according to usage intensity or when you notice reduced cutting efficiency. Store the shaver in a dry place and avoid exposing the charging base to excessive humidity.
