It might be that it is only sold in Europe at the moment because it’s a European version. European countries use 230V 50Hz mains power so it might only work there. If the product can’t switch to 110V 60HZ automatically you may need a special American version (probably available later).

Make sure you check before you order one from across the Atlantic.

Oddly, the specifications on their website show the power supply is capable of 100-240V 50/60Hz. It's also not available in the UK!? I have no idea why, though. I can only imagine it'll be a certification of some sort which it hasn't yet passed to be allowed to be sold in certain countries. I can't imagine, though, what specifications and certifications it needs to be usable in the UK when it seems OK in the rest of Europe!? It's low voltage, so can't be the light itself - must be the wireless charging pad somehow?
