I recently ordered this solar panel to supplement my emergency preparedness setup. I have an old Brunton solar panel that I occasionally used but it was limited to only outputting the 5V USB. The great thing about this panel, along with the other Goal Zero panels, is that they can be used in multiple ways. You can charge your portable device directly from it, connect it to a battery pack such at the Guide 10 Plus or Switch 8 or you can daisy chain them together to increase your power output. I plan to get a 13W and 20W panel from Goal Zero to allow me to pick which one(s) I want to take with me depending on what kind of trip I'm taking (i.e. car camping, backpacking, end of the world, etc.). As I mentioned above, these are great to have for being prepared too. The ability to chain them together means I didn't waste my money on a 7W panel that can't be used to charge larger items. With the three panels combined I'll be able to output 40W!
