Essential Info

With this in-wall combination USB charger and tamper resistant receptacle unit, you'll be able to charge portable electronic devices directly from a wall outlet. No more carrying around bulky USB adapters or powering up a computer to charge Smartphones, MP3 players, tablets, or any other USB-powered device. All you will need is a USB cable to connect the device to one of the USB ports. This energy-efficient unit uses less energy than traditional chargers, leading to savings of up to $31 per year in electricity costs. In addition to the USB ports, this unit also features one standard AC electrical outlet. Equipped with UL approved tamper resistant shutters, this unit complies with the 2011 NEC Article 406.12 requirement.

Any standard duplex receptacle can be replaced with this unit in minutes. Constructed with injection-molded housing, PVC resin, and a zinc-plated steel mounting strap, this combination receptacle was designed with durability and corrosion resistance in mind. An automatic grounding system eliminates the need for a bonding jumper in grounded metal enclosure. Triple wipe blade contacts and double wipe ground contacts also allow for long-term plug retention and can withstand regular use.

    Easy to install
    BRENT -- shawnee, KS   9/16/2013
    Smarthomes delivery and pricing where great. The TR7740 is only a .7 amp charger. It will charge cell phones & MP3 players fine, but is really slow. I you want to charge a tablet or just charge any device faseter, buy the TR7745. It is a 2.1 amp charger. It is more expensive, but worth it.
    Paul -- Los Angeles   12/18/2012
    This plug works great. I'm able to charge my cellphones including an iphone. Unfortunately the USB port will not charge my iPad. That i company really doesn't like following standards.
    PATRICIA -- brookfield, CT   6/30/2012
    It works great but the color is not a match with Lutron and Leviton Almond color. I wonder if I actually got the classic "Ivory" color but the package was thrown away so I am almost reluctant to make this report. My order says "almond" but what is in my wall does not match. I did not pursue it with Smarthome becuase it would be another visit from my electrician.
    DAMIEN -- kirkland, WA   5/3/2012
    Received in perfect condition. Easy to install... now my wife can charge her iPhone while my Windows phone is being charged, thanks to the dual USB port. Cons: in my configuration I have it installed inside a 2-gang electrical box with a 1-Duplex/GFCI combination metal cover plate, and these metal plates cost a fortune, nearly 10 bucks a piece!
    BRENNAN -- fort worth, TX   4/26/2012
    Great. As advertised.
