The speaker’s built-in carry handle and lightweight design allow for maximum portability, so you can always take the party on the go. The Adventure’s NFC tap-to-pair technology makes it easier than ever to connect your Bluetooth device to the speaker. Simply tap your device to the speaker and walk away… you’ll remain connected up to 100 feet away! The speaker also has a rechargeable battery that lasts up to 12 hours so your party won’t be interrupted. And in case your cell phone or music source starts to run low on juice, the Adventure will help you charge it with a built-in USB Powerbank. You can also take or make calls without disconnecting your phone! The Adventure has a built-in microphone for hands-free calling right through the speaker.
