It's hard to tell from the product photo, but it seems that it's a HUGE panel - I'm assuming it will be like three PowerPort Solar 21 side-by-side, which is also indicated by the name. And with both DC and USB outputs, we are talking serious camping equipment here.
If I were to go on a long group camping trip, I would totally consider this. Just one would be enough to keep a 5 to 6-person group properly powered through an easy rotation. So, if I ever find another 4 to 5 people to go camping with me, and I'm in Japan, I'll get one!
