A dangling power supply damages the 4-pin connector and DC-power input on your lights. It also makes your light stand unstable. The iKan Power Grip's Holster and strap secures and cradles the power brick and conveniently organizes your wires. Attach directly to the light stand to add stability. The spring-loaded clamps are easy to snap on and off for quick set-up or take-down and fit different width light stands. Also, its lightweight metal construction makes it durable without adding extra weight for travel.
