Flint 1 powered via PoE splitter?

I remember one mentioned that he powered his Flint 1 via a PoE Splitter.
Since I would like to do the same, can someone give me a decent/good option for a PoE splitter for Flint 1?
Preferably via a European Union based Amazon!

P.S. Flint 1 wool be used a dumb access point
