Party Squasher works in most countries with the exception of Russia and Mainland China.
In terms of power, it comes with a USB cable that you can plug to a local power plug or a powered USB port - as you often find on an internet router.
See if the Party Squasher app is available in your local Apple or Android store and contact us if it is not; we may need to make a minor release to add your country to the list of supported phone numbers for SMS alerts.
We have customers in the USA, Canada, Mexico, Australia, New-Zealand and most of the European countries. Some countries require a specific certification, contact us if you are not located in a territory listed above.
Orders for North America can be placed on our online store; international orders are managed via Amazon.
