Question about Grundig GBT Band

Can the Grundig GBT Band really play music from a USB stick? According to the digitec website, yes (connections audio connections USB (1x)). However, when I visit the Grundig website (https://www.digitec.ch/de/s1/product/grundig-gbt-band-schwarz-bt-lautsprecher-5w-bt-lcd-display-dab-und-fm-radiords-8-h-30-m-akkubetrieb--23167588), it says USB (charging) under connections. What is correct now? Does anyone have any experience? Thank you
