Sorry to hear that, mate. Maybe a few people will fail to reimburse you, so you can just keep their units.

It does mean however that I am probably going to have to use the "warranty" one to test and compile MinePeon support, if anyone objects pleas speak up

will power my five units. It can deliver 3A of current, hopefully that will be enough!
