tonies USB Toniebox Charger, Portable Charging Station Powers up to 7 Hours of Songs and Stories, Kids Gifts, 5V Input

My little girl loves her tonie box and I got this to use for charging while in the car on long journeys so the battery would last the full day.

So we came from USA to U.K. and bought this and simply used with a U.K. usb plug and Toniebox works perfectly and less bulky than an adapter.
