A:AnswerYou get a standard sony charger that charges the battery while inside the camera. If you want an external charger than you have to buy one. I purchased a DigiPower external charger at Best Buy for $25 and it works very well. Charges the battery in 2 hours.
A:AnswerThis camera does have wifi. I've only had it for a couple days. I've successfully used my smart phone to transfer pix to the camera, but have not yet figured out how to get the camera to send pix to my smart phone. I haven't tried linking my camera with my computer yet.
A:AnswerIt is! Sony's DSC-HX50V digital camera supports 100V to 240V, 50/60Hz, 70mA power. Just keep in mind that an adapter plug may be necessary for non-standard outlets.
