I always had issues with underbolted power supplies and separate power adapters, just want an IEC and everything else to be connected. This provides a huge amount of power options, in a very compact space, with a large number of add ons. It comes with many different adapters, reverse polarity, current doublers etc and cable clips to keep things tidy. On the back it has USB socket for when your iPad is dying in the middle of a gig. Combined with the SpaceShip 40, it probably gives you more power outlets than you can fit on a pedalboard this size, but as I have a couple of 12V pedals too, its nice to have that as well as the large number of 9V options. Overall the Spaceship 40 is the same size as this with or without the power strip but more robust with this.
