Recommend a rodi booster pump

[Bill Nye]

Looking for some opinions on an rodi booster pump. I have an rodi (SpectraPure 90 gpd) hooked up underneath a bathroom sink that doesn’t have a dedicated waste line I just stick it in the sink. Looking for a booster pump to increase my water pressure from 40 (on a well). Because I don’t have a permanent system it needs to be something I can plug in and then unplug and put back under the sink when not in use. Was looking at the smart buddy but it seems like a system that needs to be constantly hooked up and in a permanent location. Any suggestions would be greatly appreciated.
