I have one connected to my Icecap Gyre. I would assume it would work with the Jebao. I have only had it a month or so and haven't actually had time to test it out but it looks pretty sitting in my stand and hasn't blown up or anything.
They claim 50w at 35 hours capability. I'm not sure how that stacks up against a regular old computer UPS dollar for dollar. The big benefit on these is that they can tell your Maxspect Gyre to slow down if power goes out to extend the life of the battery. For some crazy reason they don't offer that capability on their own gyre pumps. ;Facepalm
