I lost my Ipod charger how do I replace it

My iPod Touch 7 works with any charging cord I use that can plug into my iPod. Anything I plugged the charging cord into my iPod charged.

I bought a case for it on Amazon it fits great.

You can probably find cases and chargers for your iPod on EBay.

Do you mean iPod or AirPods?

It's not the same thing.
