I’m not sure if they sell it in Germany but in the US you can buy a prepaid Visa or Amex card for a set amount, usually around 50 to 100 dollars. You do have to pay a one time fee for it (usually around $5 US) but then you can use it just like a regular credit card up to the amount purchased. Here’s an example on the US Amazon store. $200 Visa Gift Card (plus $6.95 Purchase Fee) https://www.amazon.com/dp/B07HJD9FVV/ref=cm_sw_r_cp_api_i_nTV1CbMT8NK3S
This one on amazon or you can find it at office depot
All the onewheels on amazon are overpriced and sold by random sellers who cant be trusted. If you want to use your amazon gift cards, buy some of these and either sell those for cash or just use them elsewhere.

Might as well reply for everyone to see what they need to get. It says "Blackhawk Network" in the fine print on the front or back of the card.
This maybe isn’t as good.
But they actually mail you the physical card.

Just buy a visa gift card with your balance. I believe they have up to $200 so you would have to buy 5 of them and then you can withdraw the money from the visa card. The only ones i can see rn are with purchase fee of $6.95 so it would total to 206.95. $200 visa card $200 MasterCard
