That seems to be the original iPod from 2001

Do you really have that model? 🙂

If so, it will only work with a FireWire port. It uses a standard FireWire cable (older 6-pin "400" type) to connect to that port, so you don't need a special docking cable, if that's what you mean by "charger." However, it won't "charge" unless you connect it to a FireWire port. There is no way to connect it to USB.

So, if that is your iPod model, and you have a computer with a FireWire port, which even the current Macs do not have anymore, the cables are commonly available. However, the one to get depends on the type of FireWire port you have on the computer. The two likely types are 6-pin (older FireWire 400) and 9-pin (newer FireWire 800). Your iPod has the 6-pin (400) port.

Apple-centric vendor OWC has a selection of all types

If your computer has 9-pin (800), you need a 6-pin (400) to 9-pin (800) cable. If it has 6-pin (400) that looks like the port on the iPod, then you need 6-pin to 6-pin.
