The table adapter has a steady, regulated output that allows for pedals to be daisy-chained without too much of a risk of noise and hum. However, it is not as stable and noise-free as a power supply with multiple outputs. The unit I received generated (or captured?) interference noises that would affect the signal chain even when not connected to the pedals. (Although it's quite possible that the unit I received was defective and not all Mooer Table adapters are noisy?) However, as with all things Mooer, size and price are a plus factor. I have chosen to keep this unit as a reserve. It fits nicely under my pedal board like a spare tire!
