JBL GO 1 Speaker with External Nokia lithium-ion Battery, short bluetooth function test and charging
NOTE1: the battery was taken from Old Lumia 830 and placed externally due to its size, the original controller for charging is enclosed in the green shell and it works great!
NOTE2: the music you hear in the video is from the game Psychic 5: Eternal (remake), one of my favorite arcade games from the late 80's
