Bon, si on veut bouger avec, le tout pèse quand même plus de 35 kg ... mais le résultat peut en valoir la peine pour tout bon Robinson Crusoé ou assimilé.

Extrait en VO: I opted for parts that would run my laptop in the sun for around five hours without tapping reserve battery power. Together they weigh about 70 pounds and fit in Pelican’s 1550 Case. A Sun Xtender PVX-560T battery gives backup power for two sunless days, and an inverter supplies 120 volts of AC power. The rig also has a router, weatherproof connectors, and a solar panel and charge controller to keep the computer running without using reserve power. It works great no matter where I am. I’m only in my backyard right now, but I used it to write this article.
