how should i connect two/three DC fans to 5 v USB supply ? to make laptop cooling pad. Answered
hi, i'm trying to make, laptop cooling pad as own.
hope it will help many members here,
my concept - i want to connect 2/3 DC fans(axial box fans, generally finds in computer cabinet) & through USB connector,
i want to join it to laptop.for a cooling purpose.
but, now i am simply using 1 fan to 5 v usb right now.(i had tried 2 fans at one connection but another fan goes slow, so not confident about this experiment)
can you guys help me fast.
Some Points to Consider - fans which are going to connect 5 v USB connection should not Exceed 500mA. (heard that USB should not drawn more power than it. & should not be hectic to laptop battery but still very effect).
please explain here in detail.
