Canon 550ex Flash Mod. what do you think?

Discussion in 'Digital Photography' started by earthlink news, Nov 1, 2003.

  1. I got it in my head to make a external power supply ( i.e. wall plug ) for
    my Canon 550ex Flash. ( Canon does not make one)

    I know the flash has a DC power in port on the side for external battery
    packs and looking at canon's web site I found a cable called a "connecting
    cord E" that is used to go from the battery pack to the flash.

    So it looks like I could get the cable,
    bare the battery end,
    get a regulated AC to 6 volt DC ,3 amp Transformer,
    make the connections and ....
    no more batteries while using the flash on a stand with reflector.

    The refresh should be great with all the amperes the transformer gives.

    What do you all think?

  3. The side-port is a high-voltage input, 270 volts. If you really want to
    do this, buy a Transistor Pack E and supply 9 volts DC in (substituting
    the 6 C-cells) and let the "pack" boost the voltage to 270 VDC.

    BTW, Canon charges $50 for the Connecting Cord E separately, but its
    included with the Transistor Pack E $125.
