VIC-20
C-64
A 5VDC and 9VAC power supply. When they fail they can fry your beloved C-64. The earliest models are encased in epoxy. Some of the slightly newer models are repairable. If you plan to throw away the power supply because it is old and you don't want it to fry your or someone else's C-64 - that's fine but please cut the power connector side off. Cut it off right next to the power supply so there is a long power line and C-64 connector. People want these.
C-128
A DC and AC power supply. You can cut off the end and replace it with a C-64 power connector and have a high quality power supply for your C-64. Here are some details on the US model.

These rock because there is a built-in power supply - just like a REAL! computer.
