Using this power lead is easy. Just plug the 2-pin Australian plug into a power outlet and connect the rounded rectangular female socket to your shaver. Make sure the power outlet is providing 240VAC. If you're not sure if this lead fits your Braun shaver, give us your model number before purchasing. We can't tell you if it fits other brands' models. When not in use, store the lead in a dry place. You can stretch it up to 1.5 metres, but don't pull it too hard to avoid damage. And always check the socket and plug for any signs of wear or damage regularly.
