There are not that many portable digital radios about, however this one maybe worth considering.
It has up to 10 hours playback time.
It uses rechargeable AA batteries which does make life a lot easier.
It has a backlit LCD so you can read the display in the dark and it is also able to access FM as well. It is designed to pick up only DAB III signals which is fine.
The reviews have been average, most people loving it others finding it has been faulty, however there are not many portable radios about and this seems to be the best portable digital radio on the market, the Sony portable radio has worse reviews, have a look on Amazon to make up your own mind.
The DA1000 seems to work best in London but this should change as more transmitters are added.
It’s the second best selling digital radio on Amazon.
