Jean is a happy man. He always dreamed of working from a rock by a waterfall in the jungle, rather than in a stifling office.
Unfortunately, the jungle does not come with wall sockets, making the dream an impossible one. Until now! Because now Jean has bought himself a "Sandberg Powerbank 20000 for Laptops". This gives him 4 hours of battery time in addition to the laptops own 4 hours. He can even charge his mobile phone from his new Sandberg Powerbank.
Finally he has enough power for an entire day's work in the open.
