Question: Does it make a humming sound when a phone is plugged into the USB portal and charging?
Document: The charger/outlet was easily installed but what was determined after the fact is that it does not charge Samsung Galaxy S4/S3. Plugged in the Samsung Galaxy and no charging light. Apple Iphone/Ipad devices charge with no issue. The safety on the outlets make it difficult to plug power cables in.
This product is a bit mysterious to some, in that it doesn't really tell you exactly what it will charge. If you're like me, you've got a drawer full of chargers that do one phone but not the other, or your phone but not your tablet.It's important to understand how much power this has available for devices. When you're talking about charging iPhones, iPads, Nooks, Kindles, Androids, etc, it's best to work in terms of Watts. To get Watts, you multiply amps x volts. This particular outlet has two USB ports that operate at 5V.
This is a real good idea, and the device with matching screwless wall plate looks real good, but the USB ports will NOT charge a Samsung Galaxy S3 or S4. I'm surrounded by electrical engineers and we're determined to find out why so I'll update this review as soon as I have more information. Samsung phone owners beware! Overall the receptacle works great though.
pros:- works- having the USB in the middle has a better aesthetic than the other hybrid receptacles from Cooper, Leviton, etc. some have the USB only on the top, Leviton's looks kind of weird -- this is the best looking type of outlet/USB thing out there in my opinion)- 2 usb ports and 2 regular plugs available- 2.1amp is enough for all my devices- great to be able to get rid of the travel plug and just plug in the USB cable- fantastic to combine with a phone cradle in a double (or more) gang area.
Really cut down on the number of power supplies needed for our mobile equipment. I highly recommend this unit. NOTE: make sure you have a deep receptacle box.
This outlet provides the standard outlets AND two USB charging ports. The only observation would be that they are just a little larger than a normal outlet.
Easy to install. Works great for charging any product that plugs into a USB outlet, iphone, iPod, iPad (which requires high current)
Provides the always available USB charging capability even when the charger is missing or has been relocated....as long as you have a cable you are good to go. Plenty of capacity for iPods and iPads and iPhones.
This is the best design out there, as it allows 2 USB connections and full 3-pronged plugs to be used simultaneously, while not requiring a special wallplate cover as many other products do that place the USB connections on the side. As for charging, just using it for phones but has worked great for my EVO 4G and our iPhone 4.
I need some USB charging ports in my new Jayco Trailer. I replaced one 115VAC outlet with this unit and now have two USB charging ports for guest to charge their phones. Would purchase again.Would like it to be redesign to have less depth requirements as need to change the box (enclosure) but no worries. Works great.
