Adata D8000L is a shiny, weather-resistant power bank
 

Since the primary victim of the phone thinness wars has been battery capacity (and because no-one seems to value user-replaceable batteries anymore), carrying around a backup battery has become the easiest way to make sure your phone stays ready to use all day. Adata's latest power bank, the D8000L, provides up to 8000 mAh for folks with no time to search for an outlet mid-day.
