This is a brand new, unused Lumin linear power supply. I just took delivery of a new Lumin U1 (full size U1, not the mini version) and this is the linear power supply that comes with the U1. I already have a Lumin X-1 linear power supply, so this unit is not needed.

Lots of U1 Mini/U2 Mini owners modify them to use LPS. Lumin privately confirmed with me that this LPS could be used to power a U1 Mini or U2 Mini through Pin 1 and Pin 2 of the LPS. This is of course a DIY job and you will also need to DIY the connector.
