Agree with above I found it cheaper to buy mains connection lead already fitted with plug and socket ends rather than just the cable. Crazy but true. Two things to consider. (!) Are you sure 10 metres will be long enough for your purposes. I found it too short on several sites and had to borrow extra leads hence have just purchased a 25 metre lead. Both together can now reach up to 35 metres! (2) Do check before purchasing that the cable really is 3core each core 2.5 square mm. Some are only 1.5 square mm. The cheapest ones on the internet could well be only 1.5. This was not made clear in several of the camping websites I checked before purchasing. The volt drop through a long 1.5 mm cable could cause a problem with some equipment.
