I took a pair of pc speakers that need a usb port to power it and a audio jack to plug in the audio port on the computer

So not very mobile am I right?

Then I got curious and put the jack in my phone and it worked great an could play music. But that usb jack I cant play music without it pluged in. Then the idea came to me, PORTABLE POWER BANK! I got one and it works great so yeah I put it in my backpack and yeah just need a subwoofer lol then I can rave anywhere. (••) ( ••)>¬¦-¦ (¬¦_¦)
