You to find one that is Dell compatible, they did make one for use on planes + cars (Dell).
I think mine has just two... plus and minus. This is my usual wall adapter:
I have another wall adapter; Vanson SMP-120W like this:
and that works with the same connection into the laptop as I tried with the SDR-100W and SDR-120W.
So why won`t the SDR-100W or SDR-120W charge the laptop? Is it because of wrong power spesifications? Or is it the plug?
