THE MUSCULAR POWER BANK
If its time to live off the grid for a while, don't leave home without this lim but mighty power bank.
Capable of pressing out 3 whole charges, it'll keep the music playing nonstop for hours. Before you take off, preload with the loop charge-function that charges your phone first and then the bank for an extra boost. Snap the cables back into place, then hang somewhere close by until you need it.
