Stupid long description, but super useful too. It's about the size of 2 decks of cards side-by-side, has a single two-prong AC cord, and six fast charge USB ports. I carry one in my suitcase and use it every night to charge 2 Galaxy phones, an iPad, a smart watch, a GPS running watch, and a bluetooth headset. I still need to carry cords for everything, but getting rid of the various wall warts is worth it to me.

I like it so much I bought a 2nd one for the house. I used velcro to stick it to the side of the nightstand and use it for phones and iPads for the wife (and me, when I am home).
