Can it charge over QI when its unplugged from power? In other words, can it charge my phone wirelessly from the built in 8000mAh battery?

It is suppose to. Mine worked that way but after a month or so it can't provide my phone with a full charge. The unit runs out of power after charging my phone 1/2 way. Bad quality and poor customer service.

Toby is right, all qi chargeable phones I know of will accept any qi charge signal it comes near and just start charging. I'm not even aware of a way to prevent it. Remember there is a coil inside your phone that must be aligned up with the coil on top of the radio. You can't see either so you just have to move it around until you hit the 'sweet spot'. Once you find it a few times you know just where to set it and don't even have to think about it.

The wireless charger is not required to charge the battery. Yes it supports wireless but can also be charged with the cord

If you have the cable yes, but it will only charge at 1 amp instead of the typical 2 amps... I can't vouch for the wireless charging, but if your phone is Qi comparable it will.

Nope. It charges when it's plugged in, so you can unplug it and it works without a cord. It has an on/off switch to save power when you're not using it while it's not plugged in.

Not sure on the first question. The blue light stops blinking when it's done charging while plugged in so I assume it doesn't over charge. But I can't say for sure. It gives me a good charge with just the solar panel it has. If I leave it in the window all day I can charge my Samsung GS3 probably twice every three days. If I put it in direct sunlight (I live on the bottom floor of a split level) it does even better than that.

With the qi charger you place it on it. It beeps tells you it is charging wirelessly

This cover doesn't connect to the USB jack. It works just like a regular back cover but inside of the cover are some metal contacts that touch some metal contacts on the back of the phone. Which give it the ability to wireless charge. You would need a QI charging base and if you have this cover, you can just lay the phone on the base to charge. No wires or USB connection needed.

Yes. I've used it while it is plugged in.When you says "use it uncharged", I assume you mean use it when the battery has been drawn to a very low level. If you plug it in, it will start charging the battery and when you turn it on, it will stop charging while allowing you to shave and when you turn it off (while it is still plug in), it will resume charging the battery. Hope it helps.

Don't get it man. It will stop working in one of many ways, you'll Fix it then something else will go wrong. Then you'll just toss it in a drawer and forget about it. Go with a real QI charger if your phone supports it otherwise get a QI compatible phone.

It charges wirelessly using the Qi (pronounced "chee") standard. Bought this for my son to charge his Nexus 7 while waiting for a replacement micro USB port when he broke his. It works quite well...

It will charge under a light after an initial computer, however I got a new android phone and I can't get it to charge it. It will charge my Bluetooth though.

My understanding is when it is charging it does not operate wirelessly. I usually get 5 hours out of it.

The S5 "off the shelf" doesn't include Qi wireless charging. You'll need something like this: http://www.samsung.com/us/mobile/cell-phones-accessories/EP-VG900BBUSTA

Hi Jerry, This is such a delicate thing to do for your SmartPhone. Yes, sir, it has to be PERFECT :-) I would NOT PLUG YOUR SMARTPHONE in if you have NOT COMPLETELY UNISTALLED THE QI CHARGING ITEMS... I hope this helps... Let me KNOW.. :-) Christopher "sky2112007@yahoo.com"

Out of the box it doesn't support QI wireless charging, but you could certainly add a very thin QI inductive/wireless charging receiver for you model of phone. I've got a thin wireless charging receiver in my Galaxy S4 Active.

This is not the wireless charge model. That would be the BH-220W. Looks identical, but you can set the carrier on a Qi charge plate to re-charge. Not sure it is available yet.
