The Quantum Instruments CZ2 Power Cable will allow a Turbo series battery pack to power a compatible Canon or Nissin flash. It also has been updated with a locking feature that keeps the cord locked into Quantum Turbo 3 Battery Pack sockets, preventing the chance of it falling out while shooting.
This cable is compatible with the following flash units: Canon: 430EZ, 480G, 540EZ, 550EX, 580EX, 580EX II, MR-14EX, and MT-24EXM and Nissin Di866 for Canon Cameras
