A620 AC adapter
Why not get yourself a card reader which makes life so simple and they are not expensive. They come with various card slots in case you change cameras and you won't require the ac adaptor. One can now get batteries 2500 which seem to last for ever with a battery charger which charges AA and AAA. The AC adapter can be bought from places online like B&H but only you know if you will need it.
