I don't have anything that big, but I can tell you that I have the Elinchrom BXRi 500 kit and when I plug both strobes into the mini it has a hard time with them at their lowest settings. I saw some successful tests on Youtube and bit the bullet after reading about the new innovatronix XT3 coming out this month and how it was better than the mini for handling my strobes, but I decided not to wait. I tried using them at Christmas with both strobes on the mini at 3/4 power and one of the strobes went out and I could not get it working again that day. I did not have time to work on it, and so a few days later I tested both strobes on the mini at low power and the modeling lamps on both would dim several times before each strobe was ready. I did have several successful tests in a row, but I would wait a few seconds between each test fire of the strobes. The green lights on the mini indicated that the battery was fully charged.
