Is the USB charger fully grounded?

It has both three-pronged input and plugs to go into the wall socket, and my rudimentary understanding of current Code standards is that the third prong is the grounding plug, but "fully grounded" is a function of how well your wall socket is grounded -- in other words, if you plug a three-pronged plug into a three-pronged wall socket, but the wall socket is not properly grounded, whatever device you have plugged in is not "fully grounded".

I don't know but I can sure tell you that this is an excellent product. I don't use a charger I just use a usb cable connected to the usb port and my phone is fully charged in two hours. I really recommend this surge protector.

I haven't had any problems with any type of USB port - car, wall, computer... It's a great charger for the price.

Look on the heel. There is a symbol for polarity and input voltage, ac or dc. Take the unit to a store like radio shack and have the clerk match you up. It is NOT proprietary. Test your charger with a little meter. Buy one when you are at RS.

It is grounded. All items of this nature are grounded, required by lawor it could not be sold. The 3 prong male plug on these units are the same rating as the 3 prong Daisy Chain female receptacles.

It's only solid when it's charged and plugged in but goes out when unplugged. If it works ok, I wouldn't worry about it. If it bothers you, send it in for repair.

Works fine while plugged in. However, I'm not sure it is actually charging while working.

The lights flash while charging. If they are steady then maybe it is fully charged?

No, just the usb cord. But between my phone charger and my generic usb adapter I don't have a problem charging it. I found ghe generic adapter at walmart for a couple of bucks, it has two usb ports and plugs directly into the wall. On a side note, I'm only now having to recharge my keyboard, if it lasts this long again I'm going to be even happier with my purchase!

It is a USB charge only. We haven't had much luck getting ours to work properly.

cable still needs to be grounded, outside of cable plug (gold plated part) acts as ground

Yes, that's what it is supposed to do, but I have not used it yet. I just got it and charged it. I bought it because it has a regular plug rather than just a USB port.

Not sure what you mean. It's powered solely by the USB outlet you plug it into. If you want to charge something through it that needs serious voltage, you need to plug it into a high powered USB outlet.

Yes it is. I bought an AC adapter, by itself, that has a USB port on it. I charge mine overnight while I'm sleeping.

No. Like all USB charged devices, it operates on 5volts and low current. Besides, it's made by Sony. Its up to spec and won't damage your equipment.
