Failure EP1: Building a USB 5V to 12V Power Adapter for 3.5″ Hard Drive Enclosures

DESCRIPTION

In this installment of AA Computers and Technology I attempted to build a USB 5V to 12V Power Adapter for 3.5″ Hard Drive Enclosures. I really do not like having to use a big wall wart to power my “portable” hard drive, it gets in the way and makes it really hard to move around. To get around this I attempted to power the drive off two USB ports using two 5V to 12V step-up converters I bought off Ebay for $00.99. When combined both of the USB 3.0 ports barely output enough power to keep the drive running. The initial start up current of the drive was way to much to the ports to handle (2 amps @ 12V at one point!). To accommodate for this I tried to build a fairly large capacitor bank but unfortunately I still could not get the drive to power up. I published this video so I could get some help from my viewers. Any suggestions? should I just give up?
