At the original Amazon PSU leads for far (unfortunately) no way around, because with almost 20 EUR it is not exactly a dime items, the one once in passing buys. I've been looking a long time for alternatives, but found no more favorable power supply with the right performance on the market. Also various universal power supplies in my home did not bring the required power.
An alternative would have been for me to wait for the Fire TV Stick as a second solution, but this is indeed currently no official release date in Germany securely.
