You can find the matching female cable ends.
Like this.I have a couple cables using them that I attach
to other power supplies or batteries as needed.
That makes it cheaper to replace the receptacle
if/when it melts or otherwise goes bad.
Or add one to an existing supply.If you don’t need much current, I think I’ve seen
supplies with lighter sockets sold for CB radios,
at least legal ones that don’t draw a lot of current.
Certainly putting it on a low current supply to
start with is likely to help prevent the sort of
“unintentional thermal disassembly” that can
occur with a high current supply.
