We use this power bank for off-grid camping and for power outages at home. Its a real workhorse! At our first camping trip, we were surprised at how little battery power many of our devices used, and after a week we came home with power to spare. The solar panels work great and I would definitely recommend them. (Although of course, regular a/c power charging is the fastest.) Solar panels have a little target to be sure you have the best alignment to the sun, and I discovered that you can plug devices directly into the solar panels (like a cell phone) for charging. Not a huge fan of the easel-back flaps (with elastic) on the solar panels, but they work well and once you get the panels in place, changing the angle is easy. I like the ergonomics of the carry handle on the power bank (folds down flat, easy to carry) and find it easy to use and transport. Its a bit pricey, but well worth the $$.
