The BlackDragon comes packaged in a well-designed retail package. It follows the red/black Spire colors and includes a picture of the dragon in the background. The front of the package covers the main product information and also includes the features of the power supply. The back of the box shows you the available models of the BlackDragon as well as a short paragraph about the product.

Inside the package is the power supply, nicely wrapped in bubble wrap, along with cable ties, screws, power cable, manual, and warranty card. Instead of using foam as packaging, Spire included cardboard to keep the unit protected inside of the box, which I have to say is the first time I’ve seen this.
