With a running time of up to 10 hours, the battery makes it possible to listen to music for a not inconsiderable while without a power connection. With its gun metal, the color design of the device is rather classic. The Flip Essential has a respectable battery capacity of 3,000 mAh. To establish a connection with other technical products, there is a 1x micro USB connection. Thanks to the common Bluetooth standard, wireless data transfer is made possible.
