    Purchased it on recommendation from professional live sound engineer to eliminate 9V worries for onstage preamps, pedals, etc. Thing hums so loud through my sound system. Waste of money for my purpose. Hopefully I can find an at-home use for this.

    I have now purchased 2 of these units, both actually provide 12V DC output.

    Review of 78540

    The company's service, shipping, etc were just fine. However the "9" volt power supply was putting out 14.2 volts. I also noticed that the electrical device does not show an Underwriter's Lab (UL) certification, nor does it show the country of manufacture or the manufactor's name. I haven't used it yet, as I am somewhat reluctant to chance overpowering my 9 volt transmitter.

    Upon checking the voltage, the device was putting out 14.2 volts - well above 9 volts. I have not yet tried it to see if my outdoor sensor can withstand that high a voltage. I would also note that the device shows no claim of UL approval, and has no voltage listings, nor country of origin.
