Question: The "Concert of Sound": I'm assuming the "Chime, Ding, Whistle" is to notify the device is charged.  Does it stopped when individual device unplugged?
Document: It doesn't matter which ones or any order you plug them in. The outlet itself has a microchip inside of it that detects the device connected to it and applies the correct amps accordingly.
Our first thought was to put this there, but the need to keep regular plugs forced us to find somewhere else. We eventually settled on replacing an outlet in the den, which isn't as useful, but that's hardly the fault of Leviton or this device.Overall, this is a solid investment and something that almost every household will find useful ... as long as you can find a place for it.
Extremely useful device with one problem; it doesn't deliver enough current for my Nexus wireless charging dock. I have been using the Cooper TRR745W instead which works fine. Everything else seems to charge fine with the Leviton though, so unless you need more than 2.1A per device, this should work just fine. If you need more than 2.1A, this probably won't work.
This is a great product to install in your home if you have a variety of devices that need routine charging. You no longer have to plug in unwieldy transformer blocks in your outlets since that circuitry is built into this device. My biggest issue was finding an outlet that I wanted to dedicate to charging devices. We have an older home and our outlets are at a premium. I already have the version of this product that retains one AC plug and has 2 USB outlets, which is enough to satisfy our needs.
Works well enough but the Apple iPhone cannot be charged in the off position as the USB outlet sends pulse power to the devices at the beginning when trying to charge and as we all know the apple products are always trying to stay on.
The in-wall usb charger works great. No problems at all. I have charged 1 iPad, and 3 cell phones simultaneously.It looks a lot neater than connecting 2 usb wall-warts at a time, and swap them about.
Can charge 2 kindles and 2 phones at the same time. Occasionally an iPhone will say not comparable but unplug and plugging the phone in fixes that. I bought 4 retractable cables and this setup saves me a lot of space and gets all our stuff charged quick
With a family of four gadget freaks we always have things that need to be charged. A normal outlet will only charge 2 items at a time with USB ac converters. This allows you to charge 4 things at the same time and you don't have to swap out chargers. My only suggestion is to think of the placement carefully because you will be giving up a traditional outlet when you use this.
It works as advertised. I know that's not exactly a ringing endorsement, but honestly it's a bit difficult to get too excited about a wall plug. At least it is for me, anyway. Still, this plug is a great solution to the very modern problem of having too many devices that need to be charged via USB but not enough plugs around to do the job.The only problem we had with this was finding a place to put it.
Greatest invention since universal USB charging! We put two of these in a double gang box above a side counter in the kitchen. Coupled with a bunch of Amazon Basics cables, we now have a very convenience charging station. Charging seems as fast as the OEM chargers. Devices charged so far: Samsung Galaxy 5, iPad 3, iPad 1, Samsung Intensity II, iPod nano 5g, iPod touch 4g, and an electronic body massager.
