But wouldn't there be a problem being able to package enough power to keep it going for four hours? While the empeg doesn't require a lot of power, it does require an external amplifier. I think the power requirements of the empeg plus even a minimal 50-watt amplifier might prove difficult to make truly portable. The battery pack would be more like a cantaloupe than a potato, I'm afraid...
