Bought a second hand Tom Tom One, Came with a car lead, But I tend to drive vehicles without a cigarette lighter socket, So A mains lead was a must. I went on E-Bay saw the house plug cable, read the reviews, ordered it straight away, Delivery was quick, I have used the lead twice now. Very happy with the product, even as a charge light on to show it`s working. One very happy chappie. Thank you very much
