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. Much like a suitcase, it has a handle and wheels, so it'll be easy to transport. 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 15" 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.
