I don't have a cordless iron but thought I would share a couple of items that I have for ironing. One is for the cord, which I find very helpful, and the other is an iron holder.
The cord is clipped to the top of the cord holder and doesn't go slack or get in the way like it does with some holders.

The iron rest is very good. It attaches to the ironing board at the end or the board so you get more ironing space. I also like the fact the the iron is laying down and more secure. (The screws that hold the holder to the ironing board do need to be retighted occasionally in order to keep it secure to the board and to keep the holder from sagging.) The iron can be laid in the rest either way so it is both right and left hand user friendly.
This picture is from Keepsake quilting. The site that has the cord holder also has the iron rest but the large picture wouldn't come up. Unfortunately, both sites are out right now but Keepsake says it will be back in stock in April. I have used mine for about 7 years and I am very happy with it.

Happy quilting and ironing!
