I don't know about *constant* current compared to a conventional
supply--that depends on regulation (if any) and overall power supply
sizing relative to its load--but obviously doubling the voltage cuts the
current in half. That's kinda an immutable law of physics.

** There is more than one kind of " voltage doubler " circuit.

The two diode, two cap " full wave" doubler has no current limitations.

Clint Eastwood's famous remark applies.
