Voltage is too high, and a 5A capacity will cause some excitement if the overvoltage causes the pack to short.
What is standard AC power in the UK?
US uses 110V, 60Hz. If it's just a freq change (i.e. you guys have 110V 50Hz) just swap the connector. If you use 220, you'll have to use a transformer.
