mime came with just a EU plug, had to use an adapter.
Did it come with a UK plug please?
Mine arrived today :).
For anyone that got one of these and doesn't actually have an Orbi router already, the satellite unit should work with this router, which looks like a reasonable deal and create a pretty decent mesh setup together:- https://www.hotukdeals.com/deals/netgear-rbk30-orbi-whole-home-mesh-wi-fi-system-router-and-satellite-tri-band-ac2200-22-gbps-9999-amazon-3177478?utm_source=orbi&utm_medium=email&utm_campaign=keyword_alert&itm_content=3177478
No the power supply is 100-240V so all you need is a pin converter.
