Thank you for viewing. This is a brand new 9V 1A center-positive power adapter. The cable length is approximately 90cm. If it's too short, you may want to use an extension cord. Operation has been confirmed with a Footmax KM-10, and compatibility has been verified. Although it is new, we will test it before shipping just to be sure. *The item for sale is the adapter only. It will be shipped via Click Post, but please be aware that the packaging will be simple. *Please refrain from negotiating the price of this item.
