The Blaupunkt BT11ALU Portable Speaker Aluminium is a compact Bluetooth speaker with an aluminium housing and a fabric front cover. It combines a minimalist circular design with practical connectivity: Bluetooth A2DP for wireless audio streaming, a microSD card slot compatible with microSD/SDHC/SDXC up to 128 GB, an AUX input for wired sources and a built-in FM tuner with memory for up to 60 stations. The speaker delivers 2 x 5 W RMS (10 W RMS total) output and includes a 2200 mAh rechargeable battery that provides approximately 5–7 hours of playback. A rear base supports vertical placement and a micro-USB port is used for charging.

Advantages

Direct MP3 playback from microSD cards up to 128 GB and an AUX input increase compatibility with non-Bluetooth devices. The built-in FM tuner stores up to 60 stations, and the rechargeable 2200 mAh battery allows several hours of portable use.
