    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.
    JOHN -- canyon lake, CA   10/10/2013
    Works as expected
    Rick -- houston, Texas   8/28/2013
    great, works perfect in my tens unit.
    AL -- moorpark, CA   7/28/2013
    Way too expensive. Does not indicated available current. But it does the job as intended.
    RAYMOND -- virginia beach, VA   7/27/2013
    This is exactly what I have been looking for. I love this adapter. It works perfectly.
    MATTHEW -- highland, MI   6/27/2013
    This unit works beautifully with my portable guitar/headphone amplifier. no more dead batteries :>)
    RONALD -- sewickley, PA   5/9/2013
    I have now purchased 2 of these units, both actually provide 12V DC output.
    OTIS -- howe, OK   2/18/2013
    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.
    HARRY -- toledo, OH   2/17/2013
    good service though a bit slow. well packaged items. works ideally.
    Otis -- howe, ok   2/1/2013
    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.
    GREGORY -- oakland, CA   12/13/2012
    it is self explanatory
    DAVID -- lakewood, CA   9/6/2012
    Useless and dangerous! It killed my motion detector because the output was at 13V. Plug was extremely hot. Don't waste your money.
    JOHN -- rowley, MA   8/13/2012
    fast service
    THI -- sugar land, TX   7/30/2012
    Needed this for a 9v door chime. Works great!
    PEER -- hornell, NY   7/13/2012
    Excellent. Works like a charm.
    KARL -- fontana, WI   7/1/2012
    should have bought 2 or 3 of them, S&H for the additional ones would have been free.
    FRANK -- north marshfield, MA   6/24/2012
    Very pleased. This item was extremely difficult to find.
    HERB -- saint simons island, GA   6/24/2012
    Have used this about two weeks now, hooked up to 3 ScareCrow motion activated impulse sprinklers. Wired them in series, used 9v battery connectors from Radio Shack, and plugged into a timer. Works great keeping deer out of the gardens, and now I don't have to go to each one to turn on & off; heck, with the timer I don't even have to remember to turn them on & off! Couldn't be happier! (except the shipping was a little steep & slow)

    Joe Gartner -- austin, Texas   6/15/2012
    I received the unit in a couple of days of placing the order, that was good. I plugged the unit into my TENS unit and it burnt it out. I tested the voltage output of the unit and it was putting out 14.9 volts. That is way to high for a 9v system. I put in a return request and am currently waiting for Smathome to respond. Be carefull if you order one and definitely test it before hooking it up to anything.
