Anything that uses a plug pack power supply should have a 110/120V equivalent plug pack available from US distributors or service agents.
You can use generic plug packs if you know what output voltage and current capacity to look for. If you go that route suggest you get regulated plug packs - ie the output is regulated to the specified voltage so you won't cook your peripheral. Cheap generic uinregulated plug packs are usually over nominal output voltage, relying on load to bring them down. If your peripheral is a light load the voltage won't come down enough and you risk damage to your equipment. A regulated plug pack avoids that, and usually has a switchable output voltage, so you can use it on other things if you want.
