Those packages are nice integrations, but, for instance, that one contains a lithium battery equal to two $25 "usb recharger" batteries, plus a tiny solar panel. Well...another $50 would buy you a lot more panel than that. Which of course wouldn't fit in your pocket.

But if you are going off-grid, don't plan to use a lot of power, but want a long-term way of topping it up IF you do...they probably would work well. Personally I just picked up a couple of the usb batteries on sale, I figure they'll give me a boost long enough to get me back to the grid, if I need one. There's also a little hand-crank gizmo for the same purpose, not expensive.
