With the BigBen Party Speaker Lite, you can throw a party wherever you go. This Bluetooth speaker has a 4-hour battery life and built-in light effects. Thanks to the included microphone, you can sing along with the music alone or with your friends. Use Bluetooth to connect the speaker to your smartphone. If you'd rather connect an MP3 player, use the speaker's AUX input. When your phone's battery runs out during the party, you can just connect it to the speaker's USB input to charge it.
