Hacking USB powered speakers to be Non-USB powered

Pages: (1/2) > >>

Hello,

I just bought a set of the cheapie Benwin USB powered speakers to use for their amp.  Now, I am short on USB ports, so what I would like to do is hack the power to accept a normal wall-wart style power.  What is the  voltage that USB supplies?  I *should* be able to just find a DC adapter that supplies ~ the same voltage and tap it in, correct?  Thanks in advance!

Ahh..so it should be very easy...plenty of 5V DC power supplies lying around...any reason I shouldn't do this?

Teebor:

Would a self powered USB hub not be easier?  Give you more ports as well as running the speakers?

you can get them quite cheap on ebay or a local computer store

Yea that might be easier....believe it or not, I never really thought of that!  :-\
