Question 1

Do I screw this product on on top of my existing faceplate or do I have to remove my faceplate and put this on to act as the new face plate is it safe

Accepted Answer

Hello.  Please remove the wall plate screw while keeping the original electrical wall plate in place.  Align the Wall Charger, Surge Protector, using the supplied screw line it up in the extender's hole and into the wall socket cover hole. This screw when tightened secures both the wall Charger and original wall plate to the wall electrical socket.

Question 2

can this be used on a gfi outlet?

Accepted Answer

I would not recommend even trying.  To use this, you have to mount this over the existing outlets using the supplied mounting screw.  If the backpressure pressing against the test button doesn't trip the GFI, you would not be able to reset the breaker if it tripped.  In addition, the GFI's I am familiar with do not have a center mounting screw which is necessary to have a secure mount.

Question 3

What is output per usb? each usb a port features 5v/2.4a which would be 7.2a total, not 4.8a.

Accepted Answer

* 4 USB ports total 4.8 A, 
* each USB A port features 5V/2.4A Max output. 
* USB C charging port features 5V/3A MAX.

If all of the USB ports were in use all at once, the total maximum output would be 4.8 A. Think of this as the 'total maximum output bucket.'

A USB-A port can pull up to 2.4 A. 
So if only two USB A ports were being used at maximum draw, you would max out the 4.8 A total available bucket.

So what happens when you plug in another USB device?  Well... something isn't going to get its full power draw because you've reached the max output. So, the max bucket will get shared across the active ports, and things will 'trickle charge' because they aren't getting the full juice.

If just the USB-C port is in use, and it is doing the full draw of 3 A, what happens if you plug in a USB A device that needs 2.4 A?  You are at the bucket max which is 4.8 A which is then shared across the active ports. Trickle-charge again.

Question 4

There is a little green light in a circle around the mounting screw to indicate silent operation, but why is there a green light in the 3rd usb slot?

Accepted Answer

The green LED light is surge protection indicator.  The light for this is on the interior of the surge protector.  The light you are seeing on the USB port is the surge protector light.  The LED light is next to the USB you are referring to.  I just happens to be right where the USB is on the outlet.  It is just a reflection of the surge protector light.
