QFX's Portable PARTY Speaker has you covered for any occasion. This versatile PA speaker rolls on into events to pump out music or amplify announcements. Once it's in place, it can stream music from a variety of sources: wirelessly via Bluetooth-enabled devices, through USB and microSD card slots, or connected with a cable through the aux-in port. No matter what you're playing, the speaker's 8" woofer and amplifier ensure that everyone can hear clearly. The rechargeable battery lasts for 4-hours so you can stream music even in places without an outlet nearby.
