Quantam QB23 10 ft. (3m) Extension Cord for use with Quantam Battery 2. The QB-23 extends the working distance between the Quantum Battery 2 and any of the power modules available for it (such as module S, M, P, or others). Insert the plug end of the QB-23 into one of the Quantum Battery 2 flash outputs. Plug the power module into the socket (other) end of the QB-23.
To prevent accidental disconnect while using the extension cord, secure the power module cord and extension cord in the clip provided. You may also secure the extension cord by looping the plug through the "D" ring on the Quantum Battery 2. Then insert the plug into a flash output.
