Hello,

I have a pair of speakers that need a 13V and 2A DC power adapter or wall
wart. I lost its wall wart and found a wall wart for another device, which
I
have no idea what its for.. it gives out 15V and 400mA DC.

The power adapter I found said on its back that it must not be used with
any
other device except..[some brand name]...

Now, I used it with the pair of speakers and it worked!!! Now, i'm
worrying
that this configuration could cause it to explode or something....

Will it do any harm???

P.S. (im cross posting to two newsgroups...)

The speakers if they indeed need 2A to operate may damage the 400mA adapter.
The extra 2 volts may or may nto harm the speakers, though likely not. Your
best bet is to find a 12V 2A adapter since 13V is not a common value. Try
Radio Shack or various online merchants such as DigiKey.
