You'll need to check around and try disposable cups ahead of time to see what works. I found the tubing that came with the disposables was too small for the Trek so I used a wider diameter tubing (Pari wing tip). Also, it depends on the quantity of what you're nebulizing. There are a few variables to consider. Be prepared that you will likely spend more time nebulizing than with your larger compressor at home. It's a trade off.

If it were I, I would also pack reusable nebulizers with a Drizzle pot (Amazon) for boiling (ramen pot) and a container to soak the stuff in prior to boiling. I tend to be over prepared when I travel. It all really depends on your disease condition and how often you need to nebulize.

The ultimate travel nebulizer, IMO, is the eFlow. very pricey. It occasionally goes 25% off. Needs to be boiled or baby bottle sterilizer.
