"Those batteries have nasty voltage regulators in them....."

True. Not just nasty voltage regulators but switching regulators. You are not running purely on battery power with those USB battery devices.

....isn't that defeating the whole point. "

Sort of in terms of quality DC power.

The main technical advantage I can see in using a USB battery is that it is isolated from the AC mains. But you can achieve the same or better with a quality switching power supply or linear power supply on an AC power regenerator. I have the old PS Audio Power Plant P300 for AC power regeneration and isolation.
