Via a standard US style power adapter (included). This adapter supports up to 240V but does not have interchangeable plugs. ION also has a 2.1mm barrel jack near the base that can be powered off any 5V 2A+ supply.
EDIT: If you need a specific power adapter for your region, please send a message to us and we will see what we can do!
At this time we do not have plans for a Windows Phone version of the app by ship date. Depending on the success of the project and customer demand, we will consider building a Windows Phone app after the first batch of IONs are shipped out.
