The HEX is our first ever Bluetooth Speaker that also functions as a Lantern, a Flashlight, FM Radio and a Micro SD Card Reader ALL-IN-ONE. It has a USB port for charging mobile devices and also a Micro USB port for rapid charging. You can use any light source to keep your Bluetooth Speaker charged which means you can jam your tunes outdoors or even in your dorm without worrying about missing your favorite song. With the 2200mAh lithium-ion battery the HEX can enjoy 20 hours of listening pleasure at mid volume. As a lantern it can give you up to 60 hours on the 40 lumen setting or 8 hours @ 400 lumens and can turn out 10 hours on the flashlight. So you can take your tunes anywhere or keep it handy in your glove-box, kitchen drawer, garage, or boat.
