Any quality DC adapter with a center positive barrel jack will be marked with the following symbol:
Any adapter labeled as compatible with the MPC One, MPC Live, and MPC X will work with ALL of the kits using the standard barrel jack.
Advanced PSU Kit:
You will need to look for a +45W DC adapter capable of outputting between 18-20V.

Boosted PSU Kit ONLY:
The boosted kit is compatible with any DC adapter capable of outputting 12V, 3A.
The boosted kit is also designed to work with the following 12V battery banks available on Amazon.
About 2 hours of runtime was accomplished using the small TalentCell YB1203000. (link)
The bigger YB1206000, (link) has double the capacity. So it should get about 4 hours of runtime.
