  • I have no idea how i missed this episode lol.

    I'm thinking of doing the same idea but making a usb panel so that during a party i can have everyone charge their phone/tablets/laptops/etc..

    hopefuly around 10-12 usb ports.

    My question is how many amps/milliamps is the 5v rail on a power supply actually putting out? would running off of that single 5v rail be enough to get 1.5 or even 2a per port?
