I'm not sure how the Luna Cycle compressor will connect to an ebike power to be powered by USB? Looks like you have splice into the wiring harness?
Didn't check the price and never used a CO2 inflator. Usually it takes me a few minutes to get my MTB tyres up to 40 PSI which is adequate to get me home after repairing a flat. Going above 40 PSI takes ages with a hand pump, so I normally pump my tyres up to 65 PSI before leaving home using the big air compressor. I presume pumping hybrid/road bike tyres is a lot more difficult because of the higher pressures they require.Looks like a clever product but a bit pricey. On the plus side, It has the ability to recharge from USB equipped ebikes. Other than that, I don't see the advantage over lighter, smaller and cheaper CO2 inflators.
