I wish I had read the previous reviews before placing the order as they are all correct. This power extension cable is the wrong size and of no use at all for the camera. It's relatively cheap and so when discovering it was wrong and planning to return it it turned out the cost of postage was as much as the item itself, so wrote off the fiver. This isn't the fault of the seller but of Amazon for wrongly recommending it. Given all the comments on this issue you would have thought that Amazon would have changed it.
