That connector was micro-USB, and almost all phone makers use it now. Unfortunately that excludes Apple, who like squeezing their customers for all they can get on proprietary stuff (not a fan!).
Saying that, a plug that has a USB output is the best start, then at least all you need is cables - apple for ipod/pad/phone, micro-USB for other phones, you can get a USB->DS cable (be aware connector changed between DS Lite/DSI and XL/3D, get the right one). Camera will probably need a specific external battery charger (depends on camera, may use mini-usb, NOT the same as micro-USB). DVD may well be proprietary. All USB plugs I've ever seen can cope with 110-240V. If you search on ebay for "worldwide USB charger", you get a whole selection that have changeable plug prongs for uses around the globe.
