If you're just tent camping for a couple of days, of course, your laptop with some external battery juice should suffice. However, for those that live the"Airstream life" and work from "home", you might want to consider the Kanz Field Power Desk. This mobile desk compliments a Cabela folding chair rather nicely and resources its power via solar panels, allowing you to setup office anywhere! It even has a satellite internet option for those who need to commune beyond the forest. Two models are available with 120 Watt/Hours and 240 Watt/Hours respectively. Learn more at Kanz Outdoors.
