Notes: * Wattage is shown on the back of some items, either as for example 4W or 4VA. It can be calculates by multiplying the Voltage (V) by the Current (A). Mains connected items run at 240V Battery operated items run at the battery voltage x number. e.g. 1 AA Battery = 1.5.V 4 AA Batteries = 6V ** The cost per unit can be found on your most recent electricity bill
