Bo I recently bought just what you describe
I have tried it on several client's laptops and it seems to work fine
I bought it on Ebay. I like this one because the power supply has a
pretty common size tip so you can use a regular set voltage supply
with the adapter plugs, if you wish.
 The power supply  has a slider to set the voltage
from 15 to 24volts in increments
 it is 90watt so it supplies
 enough amps to power about any device
 search eBay for " 90W 10tip Universal AC Adapter Power Supply "
on Ebay and you will find it. Usa seller name is"laptopz-outlet"
shows $13.80 buy it now with free shipping
when I checked just now.
