Well packaged, received in good condition and excellent delivery time (13 calendar days from order). In most of my projects, I use a distribution line of 9v or 12v and step it down with a buck converter in the local device. These buck converters are ideal for that. I find these step-up cables useful while I am developing the project so I can power it from a standard USB power bank That keeps everything isolated while I am experimenting. I recommend these boost converters.
