This is more than just a cooler--it's a portable music player, too! Audio components include a 2-speaker music console with MP3 connection, an AM/FM radio, bass & volume control, and an led power indicator. The console is powered by 4 "AA" alkaline batteries (sold separately). In addition, several large exterior pockets provide towing space for personal items such as mobile phone, sunscreen, and more. The telescoping handle, wheels, and swing-up side handles make transporting and carrying a breeze.
