I have been using one for a little over a year now. Has
worked perfectly, cost only $17.90 and it comes with a
selection of tips

Have been using a Toshiba laptop. Just got a new Compaq.
The only change I had to make was to move the selector from
19 volts to 18 volts. Tip was the same.

I just received one from N4UAU and the workmanship is faultless. I got the
plug-n-play one I only have to supply the laptop plug. It's great! Leon
