i got this a couple months ago on sale and use it all the time ,it can charge phones battery packs it came with a aaa/aa battery charger i use it near every week to keep my gaming controller batterys going. and i just leave the panel chargeing a bluetooth speaker in my window. it also has a usb port on it, you can daisy chain wih it. it has hooks to hang it from stuff. its just a really awsome little device you can get. and come SHTF ya im not gonna be running any major stuff off of it, but it would still be quite a boon. very good for those small electronics electric razer, mp3 players, talkies, cb's. ya itll take a little bit, a couple hours for most things but it does work. suprisingly well.
