This is an AC adapter, and unfortunately, nothing more. There is no USB cable, although I wasn't very surprised after Sony did the same thing with the PSPgo.
-An official Sony product, so it won't void your warranty if you break the Vita. A unlicensed third party adapter technically voids any warranties, but only if Sony somehow found out you had used one.
-Too expensive for only half of what you need to charge the Vita, you'll need to buy another USB cable seperately.
-Sony has placed grooves outside of the USB port to prevent other USB cords from being used with it. Some USB cables will fit, but you shouldn't plan on using it as a multi-purpose charger.
-At the time of this review, it's the only AC adapter approved by Sony. It's in your best interest to get licensed products if you bought an extended warranty from Sony, the terms specifically state that damage caused by any unlicensed accessories will void the warranty.
Sony will hopefully license power accessories from third parties at some point, but you don't have many/any options if you want an official product until then. If you want a Sony adapter, I suggest getting a PSPgo AC Adaptor
, it'll probably always be cheaper than this one. I apologize for not knowing the proper term, but the input and output numbers (voltage?) are the same as the Vita's AC adapter. Both adapters have grooves in the same place designed to prevent other USB cables from fitting in them, so either adapter works for either system.
