<p>A pay as you go electricity port, comprises an automatic switch, a plug socket 7, an energy cost meter, and a payment station 5, wherein the automatic switch provides an amount of electrical power to the plug socket as measured by the energy cost meter up to an amount paid for through the payment station. The port may communicate with a remote master registration system which is able to send a code to the electricity port to enable operation. A user may have to complete an online registration process in order to use the port. Payment may be made via a card reader and a keypad enabling a user to pay using their credit or debit card, or via mobile telephone communicator to allow payment via a mobile phone. The energy cost meter may be operable to measure the electrical power used and calculate the cost from the used power. The switch is activated to supply power when payment is received and the power supplied does not exceed the payment. When the supplied electricity exceeds the value of the payment, the switch is deactivated and power is cut-off. The invention allows users to pay for charging their personal electrical devices.</p> |
