Hi Patti,
Many thanks for the question!
As you know, here on the island of Ireland we use different plugs and our power is 230V~ I would suggest that you contact the manufacturer of the scooter charging device or their agent to see if they have such a power convertor device or one that they would recommend.
It is possible to buy one from well-known online shopping outlets. You would just need to check that it is capable of use with your scooter charger due to any heavy-duty requirements.
Have you already made plans to come and visit us?
