A lot of portable radios are powered by 4 AA batteries or mains electricity. Some radios, however, can be charged by USB cables to a PC (must be a built-in battery) as well as having AA batteries - but no mains charging.
Thank you all for your input. I'm not too bothered by the make/brand, it's the simplicity of effecting presets I'm after. Some maker's models differ from other models from the same source.
