Yeah, that's pretty worst-case.
Think about it. These things are
laptops. They don't use 120VAC. They need power adapters to turn wall power into DC. So eliminate the middleman (and associated power losses) by using DC directly! You'll have to check the output voltage on your specific computer's power adapter first, but a pair of robot batteries in series yields 24VDC -- exactly what my iBook wants.
