There’s a device for that called the Norelco Genius 2D. It is suitable for permanent installation in your car on the premise you have access to an outlet. It costs $50. If you have street parking only it is questionable whether you will be able to leave a car a whole week without incurring the wrath or a municipal agency. If you have parking lot parking only in an outside lot at an apartment complex of some sort, you might prefer a panel, though I more that you can get a kind that you leave on the dashboard that plugs into the lighter socket for a similar price —without the convenience of an integrated form factor admittedly but still.
