Is it OK to power a G3 Lombard from a PowerBook 1400's power supply?

I had two 1400 style PSUs which unfortunately broke so I bought a new one a couple of years ago. I started using that with a Lombard which I obtained last year and about 6 months ago, it also broke. So now I have no power supplies and no way of powering either the 1400 or the Lombard.

Did I ought to get separate power supplies for both computers?
