US is 110V, Most of Europe is 240V 50Hz, with many many different plugs,
A 240V-110V inverter would be 12-25lbs 5-10KG deadweight & many times the cost of a cheapo compressor, (at least those used on building sites to run power tools)
I have seen a battery powered compressor capable of running an Iwata, possibly with 7.2v R/C gear batteries, with mains chargers capable of running on 110V or 240V... Truly portable.
