Forgot the name, but it's made by Renogy. They make the 100W panels people use for residential/commercial applications.

The unit I got has 4 panels, terminated to one USB @ 5V (obviously). I also got a PortaPow USB meter/monitor. This is real handy to get the proper angle and to monitor the load(s).

Also got some heavy-duty "charge-only" USB cables for a more efficient charge w/ the data pins disabled.

In the photo, I'm charging a Goal Zero Guide 10+. You can see it actually draws more than the standard USB 500 mA.

Edit: I like this small portable setup. Next setup will be with a portable 12V panel.
