Same here. Although I'm using a bench power supply I intend to supply a 3V regulator from USB power in the finished product.

On that subject here are a few consumption measurements, in case anyone's interested:

WP34S all values mA

Erased, waiting for flash command 8 mA
Idle, no buttons pressed 0.17
Idle, button pressed 0.30
Scrolling through X.FCN 0.85
Running STOPW application 1.37

The above were in FAST mode but SLOW mode made no difference.

Contrast this with the HP50g:

idle 13 mA
pressing a key 28
drawing a plot 76
beep 50
self test 67

... that thing is a beast!
