Quality batteries hold up to 10gigs (☒hours of playing thru the night) for me. 9v batteries on the P1, can hold not more than 1/3 time of this AAA battery setup. Power of the amplification and the power consumption is way better than it's bigger brother. And thats the only thing that is better on the P1. If you make a custom cable 2 xlr mono > 1 xlr stereo it works as a stereo amp flawlessly. It is much more comfortable to use it for a standing setup, because, it is not as bulky as P1. P2 is a much better than a P1 amp in both: size and power.
