Hard to believe that the small device can produce as much. I use the speaker on my sites, rather than the so-called "construction site radios", for which one could often take an elevator to take them to the second or third floor. The speaker's also a radio, when you connect with the supplied cable or without power. If then believe presenters, you would annoy me with their chatter, I switch up my playlist via Bluetooth, and all is well. Only while charging the radio reception rushes occasionally, then you have to try around a bit until it sounds good again. For my way of using a strong buy recommendation.
