Samson PB10 X2?

[wilkinsi]

I've probably asked someone about this before but can't find the post in whichever forum it was placed...

I have ONE power conditioner in my room. There's only ONE mains outlet. I'm expanding the number of rack devices which would exceed 9 outlets. So the only way to power both PB10's is to power one from the other. Should I be going by the number of watts used by each device or something else? Or is this a no-no? I could use both PB10's independently, but the 2nd mains outlet is outside the room, which would mean I would possibly damage the power cable with the door.
