Innovative Solutions for Fast and Convenient Charging

Combination USB chargers give you the ability to charge virtually any device from a standard outlet without the use of bulky adapters or powered computers. Quickly charge smart phones, tablets, e-readers, MP3 players and more while also powering traditional electronics such as lamps or televisions in the same receptacle.

Tamper Resistant Shutters (Shown Above)

The National Electronic Injury Surveillance System (NEISS) reports that more than 2,400 children are injured each year by inserting foreign objects into receptacles. Tamper resistant receptacles feature a built-in UL listed safety shutter system that prevents the insertion of foreign objects into the receptacle openings. This means that the safety shutters only open when a two-bladed prong presses simultaneously against the two shutters for added security and protection.

Perfect for Phones iPods but not for Tablets

Perfect for Phones iPods but not for Tablets
I installed these outlets after I got tired of the phone chargers walking off. This is because I have 3 daughters who are always losing them then "borrowing each other's without asking". This was especially true when friends came over with phones needing charged. Anyway I am happy to report these have solved the issue of the disappearing adapters as they can't walk off. I now have a surplus of adapters I save for traveling/vacation. So far they have charged the Droid Razors, IPOD 4th Gen, and regular phones. When the charger is charging the accessory a red led light glows. After charging is complete the red light turns off. Update: However as other reviewers have noted Tablets require higher outputs will only charge when powered off! My HP tablet indicated it wasn't able to charge however after I powered it off it charged fine overnight. Not ideal but worksI installed 3 of these in 3 bedrooms and plan to get at least 2 more for the living room and kitchen. They don't carry anything like this at Home Depot, Lowes, or Menards yet, so this is a must for early adopters.The installation is very simple just connect the Black wire to the black screw and the white wire to the silver screw.Important:One note that needs mentioning is this outlet only has 1 set of hot and neutral screws vs the 4 screws in typical plugs. Directions in the box indicated this was for the end of a circuit.The location you want to install it at is likely in the middle of the circuit so you can double up both the hot and neutrals on the 1 connection point. In the event you don't have adequate wire length for your connection. Then you may need an extra 6 inches of Hot, Neutral, and Ground Wires and 3 wire nuts to pigtail the circuit on.Also they are UL rated. Its on the side of the box.

4.0 out of 5 stars High quality -- if you will give up one 120v socket.
Reviewed in Canada on April 14, 2017
Bought this because there are too many "cheapies" out there. Most of those have reviews saying they broke in a week or month. I've installed two of these in a high traffic area.

Choose Cooper because it's solidly built, has a great reputation, and I know I can count on them. The build quality is fantastic but what you're giving up is a 120v socket. If a very high quality USB outlet is what you need and you can sacrifice one 120v socket, this is for you! It installs FLUSH with no protrusion, unlike all others on the market (see photos). The back is also low profile as well so if you have a shallow wall box, this is great.

Overall, GREAT high quality choice if you're willing to live with just one 120v socket.
