So sorry for the delay in response. The Rohm is very compact and portable, and measures 3.75" x 3.5" x 1.75". Please let us know if we can help with anything else.

Thanks for your question. A full charge on the Rohm will last anywhere from 10-22 hours. (This is because Rohm does not feature a nightlight.) Again, louder volume = more battery drain. It is also possible to run these units while they are plugged in. Our FAQ section has all the answers you need!

So sorry for the delay in response. Yes, the Rohm has 4 volume settings and you can choose between the bright white noise, deep white noise, and the gentle surf sound settings. Please let us know if we can help with anything else!

Do you have the same white noise machine with dual power and hz for Europe, as the movil phones and cpap machines?
What do you recommend?
We do not recommend using the domestic Dohm internationally at all. The voltage for our Dohm DS is 120V and these units run on approximately 18 watts of electricity. We have found that even with a "low wattage" converter our domestic units will not work, or if they do it is only for a short period of time. We do make a Dohm DS 240V unit specifically to be used outside of the US. It comes with either a EU, UK, or AU plug. It is available from most dealers in tan. We do have it in black and white but those are only offered from some of our international dealers. You can find it here in the US from earplugstore.com.
We currently have two options the first being the our Zohne. It is our travel model. This unit has a dual voltage transformer that will automatically adjust to the power being used. This way it can be used domestically or internationally effortlessly. It comes with a travel bag and the EU, AU, and UK plug adapters. Perfect for traveling internationally and domestically. Please call us direct if you should choose this option. A second would be our Rohm. It has a rechargeable battery and is quite small and very portable. You charge it using a USB cable so you can use it most anywhere. Here is a link to our store page, marpac.com/shop.html, just scroll beneath the Dohms and you will see the Rohm.
