These days the specific MP3 player is not really the question. You should be able to buy whatever MP3 player best fits the features you need and then use its "charge by USB feature" in addition to something like the following (USB CHARGER FOR CAR OR WALL OUTLET): amazon.com/WORLDWIDE-USB-CHARGER-WALL-OU... to achieve your wall outlet charging needs. The specific model of unit of usb charger is not important - there are numerous different brands, the link is just an example.
There are lots, actually. I know cheap ones which do not need to be connected to the computer to charge. You can check out their site: cheap mp3 players.
