Yes, I could tell it was a UK plug. That just means that the charger has more work to do to lower the voltage from 220 to 8.4 volts DC. Other than that I have no idea how stable line voltage is inside the UK. This I do know; If you get hit ( momentarily ) with 110volts AC over here in the states it hurts like the Dickens. If you get hit ( momentarily ) with 220 volts AC ( and yes we have that here too in the states ) that will knock you on your arse. That said, I can only imagine what happens to an electronic device when the 220 power supply interface shorts out. Ah the smell of melting plastic.
