Having a brew when you are away from home can sometimes be difficult. You may have a hotel room without a kettle or just fancy a cuppa after driving to a remote but picturesque location. Fear not, as there are a number of options available for boiling water without having to take the cumbersome kitchen kettle with you. If you have a mains electrical plug outlet available then travel kettles are ideal. They are basically compact and lighter versions of your standard kettle, boiling enough water for up to two large cups of tea. If you are away from mains electricity but are in your vehicle, then you can use the cigarette lighter socket to power car kettles. heated mugs and immersion cup boilers.
