What? Still no answer? Let me see if I can help. ;-)

This charger is marked as "use 10-16V DC only" and has a figure 8 (IEC C7/C8) style connector as input but I don't have a suitable input cable.

First of all, the regular AC-adapter/charger for the 34C is the 82090B (220 V) resp. the 82087B (110 V). It plugs directly into the rectangular socket on top of the calculator. There also was an external charging cradle + battery set that was used with the same charger.

As far as I can tell, the 82144A is a charger that is intended for the 12 V output of your car's cigarette lighter. If I understand you correctly, you seem to have just one half of the complete charger. What you need is the other half that plugs into the lighter socket and where the other end connects to the input you described.

But... that's not the regular AC charger. Maybe you can build your own 12 V supply that connects to what you have - this may be answered by others. But I think getting the regular Spice charger, i.e. the 82087B or 82090B, would make more sense.

Regarding the 8-shaped socket you described: Please take a look at this website. The Sting section shows a picture of the regular 82090B charger. Now take a look at the 82066B (next picture above). It's just an idea, but do you think this plug would fit?
