  • What's Included
  • With the Cooper Wiring in-wall combination USB charger and tamper resistant receptacle unit you'll be able to charge portable electronic devices directly from a wall outlet. The Cooper Wiring TR7746 provides quick and convenient access to charge virtually any electronic component including smart phones, tablets, e-readers, cameras and MP3 players. All you will need is a USB cable to connect to the one of two USB ports on this unit. 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 two standard AC electrical outlets 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.

    Not compatible with Samsung devices. Charges other brands but not Samsung. This is according to Cooper tech support.

    We got two of these to use in our kitchen where were plugging in our devices to charge. They work GREAT! Now we have no bulky chargers laying around AND devices charge up much fast than before. I did check the circuit we planned to use and it is a 20 amp circuit common in kitchens. Be sure to check the amperage of circuit you plan to use and order the properly rated receptacle, either 15 or 20 amps.

    Works great! I can leave the cords plugged in, and the light only goes on when a device is actually attached to the other side. It charges quite fast! My only quibble is that the writing on the face is oriented for ground-prong-up installation (which is more common for industrial receptacles) as opposed to ground-prong-down installation (which is more common for residential receptacles). But it's not like I ever look at that any more. :)

    This has been a great kitchen upgrade. Now I can charge phones AND make toast at the same time!

    Purchased this to replace an existing duplex receptacle in the kitchen where we're always charging USB-type electronics. Was easy to install thanks to the excellent installation instructions for the do-it-yourselfer. Was a bit pricey probably due to the 20A rating but still worth the money. Have already recommended it to some friends.
