Portable Radio THOMSON RT400DABBTBK — FM, DAB+, Bluetooth, USB

The THOMSON RT400DABBTBK is a portable radio that supports FM and digital DAB+ reception, and includes Bluetooth and USB connectivity for flexible audio playback. Designed for transportable use, it enables listening to local FM stations and digital broadcasts, streaming audio wirelessly from smartphones or tablets, and playing or charging devices via its USB port. The compact form factor and straightforward controls make it suitable for home rooms, travel, and small social settings where multiple audio sources are useful.

Advantages

This portable radio combines FM and DAB+ reception with Bluetooth wireless streaming and USB support in a single unit, providing a range of listening options without additional equipment. The integrated digital tuner offers clearer reception of DAB+ channels where available, while the FM band maintains access to traditional broadcast stations. USB connectivity allows playback from USB drives and can supply power to mobile devices. The device’s portability and simple interface make it practical for quick setup and everyday use.

Suitable for

• Listening to local FM stations and DAB+ digital radio at home
• Wireless audio streaming from smartphones or tablets via Bluetooth
• Portable use during travel, in offices, or in small gatherings
• Playback of audio files from USB drives and charging low‑power devices

When it may not be suitable

The RT400DABBTBK is intended as a compact portable solution and may not meet needs for high-fidelity audio or large-room sound. It does not replace multi-speaker home audio systems or professional-grade equipment where powerful amplification and advanced audio adjustments are required. In areas without DAB+ coverage, digital reception benefits will be limited and users will rely primarily on FM reception or Bluetooth streaming.

What to consider before purchase

Regularly check and remove unused files from USB drives to ensure quick access to desired audio content.
