Since the Newport was designed from the get-go to be the ultimate portable speaker, we made sure the battery is big enough to keep it running for up to 12 hours. To ensure the music never stops, we included a USB port to charge external devices and made sure the battery has enough capacity to fully charge a smartphone twice. Battery operated and compact size for portability. Built in microphone for hands free phone use 30 Watts of power. Two woofers and one tweeter for natural sound reproduction. Plays your music via Bluetooth or the built in 3.55mm auxiliary jack.
