I need a cord for a shower radio.

I have an unbranded/generic shower radio I got on Wish.com. It is NOT aYaesu VX-6 , but there was no option for unbranded/generic.

I lost the power cord. Where can I locate another one, without having to buy another shower radio, and how much can I expect to pay?

I have included a picture of the radio, and the area where the plug goes-in.
