The US charger is not dual voltage (120 only) so you need a step down transformer that is over 600 watts. (the ego rapid charger is rated at 550 watts) Something like this: https://www.amazon.com/International-Voltage-Converter-appliances-overseas/dp/B000WQ0MTG
If you just use a plug convertor you will burn up the US charger in the UK.
