Question: Concerned about the ringing that some reviewers mentioned. Is this a big deal?  Seems like it would be really annoying.
Document: Conclusion: I had to solder for peace of mind.I wish I had gotten this for free like the rest of the reviewers here (my review is the seventh one here and the first one not from Amazon Vine).
Only while using this unit. I can't replicate it on demand and it seems very random so I can't offer a reason. It just happens. Not enough to make it a deal breaker but it does happen.This product is still much better than using four power outlets to charge all of our most used devices and only takes up half the space.
With most portable electronics standardizing on USB chargers, moving the charger circuits into a wall unit is a good idea that helps avoid the clutter. This unit, however, is not a complete package. One would need both a wall box and a face plate, both need to be purchased separately. Once the pieces are available, installation is just like adding another wall outlet.
Works as described. Looks good, too. It was really exciting to hide all the charging bricks out of site and use this outlet for everything.
We had a regular plug by our charging station for our phones so I replaced the receptacle with one of these. I really cleans up the look and works great.
Works well. I installed this in my head board to help clean up the tangle of wires. Also we do not have to deal with AC to USB adapters now.
Lots of electronics plugged into this outlet and it charges quickly. I would highly recommend this if you need a dedicated USB charging station.
Really, really handy. Several friends have purchased after seeing it installed in my kitchen (the default charging station for everyone in the house). I went with 4 USB ports as I already have enough electrical outlets available. Charges phones and tablets without a problem.
Picture shows a faceplate - you dont get one with your order. Not sure where you find the snap-on style faceplates (there are no screw holes in the socket itself for a screw-in style one so it would have to snap onto the socket itself.
It is big! fits very tight in an existing socket. If you have lot of wires tucked inside a socket hanging loose, putting this in will be difficult. You may have to trim the wires inside and minimize the lengths so you will have enough space to put this in the socket.2. Minor one: we lose the electrical socket with this!
Answer: yes
