[Q] Qi Pad with loop through?

I have done some google searches and came up empty, but i figured i would ask. I am trying to find out if there are any Qi pads that have a power input as well as an output as to connect a second Qi pad or a charger direct from another device. Has anyone seen anything like this?
I would love to be able to cascade 2 Qi pads as well as a non wireless charge enabled device and only have 1 line go back to my outlet. I don't see why this would not be possible.

The only charger that I've seen and do own is a Lugulake that will charge two devices.

The RAVpower charging pad Qi enabled can charge two devices at once. Plus you can charge a phone in your pocket https://www.youtube.com/watch?v=nFPII0dKyC4&feature=youtube_gdata_player

I have the energizer 3 position charging pad. Has 2 qi chargers built in for 2 phones and a usb port on the side. I've used all 3 at once. Works fine for me.

[How-To] Moto G wireless charging (Universal Qi Receiver)

I've received my universal Qi wireless receiver today. The receiver is smaller than I had thought and fits perfectly into the Moto G. Since our phone lacks internal preparation for Qi (like it can be found on the Samsung Note 2), the connection is made via a micro USB plug. The backdoor can still be clipped on without being disturbed by the Qi receiver pad or its flat band cable. Charging time should be about the about the same as charging the phone from a PC USB port that doesn't output more than 500mA.
This solution is obviously for those who don't need the phones usb port on a daily basis.
The adapter on the left picture (and in the video) is from ebay and is the one that arrived here first. I’ve changed the cable routing to remove the ugly bulge that was visible on my first picture. This adapter outputs a maximum of 500mA and can be purchased from ebay.
Make sure to purchase the "interface layout A, narrow interface up” variant.

17.Jan.2014 - The picture on the right shows an adapter purchased from DealExtreme, that arrived here yesterday. This adapter delivers up to 650mA and the flat band cable comes out of the lower side instead out of the backside which removes the need to bent over the cable.

Both adapters work well, so don't worry if you've already bought the one I've first reviewed. (I have both version in use on different phones)
Here is a small video that shows me placing the receiver inside the Moto G:

Update 13.02.2014
From my testing I can tell the following:
1. An unrooted Moto G needs to be screen locked (I use the pattern lock type) or it will refuse to charge due to the missing pins. You can unlock the screen while it is charging as long as you don't lift it from the qi charger. (tested on 4.3 and 4.4.2, DE and FR firmware)
2. Root in combination with dubidu's tool makes it more straightforward but is not required.

Should you wish to buy an adapter for your Moto G, make sure to get the "narrow-interface up" variant

Nice. Can you tell us where you got it from -- is it just one manufacturer making these?
Cheers.

I just bought it off amazon (hooray rewards card, it was free).

Thanks. I had looked on fleaBay and it looks like they all have the same packaging. I imagine any qi wireless charger thingy should work. In theory.

anyone know if this would work through an otterbox case? or I guess if this would even work with one due to the fact the part that plugs in sticks out a little bit...

I've bought it here:
http://www.ebay.com/itm/261348107126
The auction uses the same pictures as used in the amazon offer posted by JCBomb, might even be the same seller.

This is cool! I just hope there's like another way we can integrate that wireless charger.

Just saw your post at android.hilfe and started looking for some charger, it's indeed a neat solution.

Are u guys using this wireless QI receiver? I'm going to buy one next month, D: . Just for curiosity, how much time do u guys spend to get a full charge with the QI

Guys i found this one at dx.com
http://dx.com/pt/p/micro-usb-qi-wireless-charging-back-clip-black-253066

Those kind of product are not so great are chaging, basically it's almost the same power that if you charge through uSB = 500mA.
What you need to check is the charging value, sometime it's :
- 400mA or less (avoid it, will take ages to charge),
- 500mA (just like your regular USB charger),
- 1000mA (great ones, will charge just like a wall charger, twice as fast as the previous model).
So the one at DX is great, but they're cheaper on ebay, plus you can choose between Black or White - http://cgi.ebay.fr/ws/eBayISAPI.dll...eName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

This one was the cheapest (around £15) I could find and works fine.

wow, so cool :good:

Am I the only one thinking about finding the plug they use with all the pins intact and integrating a micro sd card into it for OTG storage? Wireless charging and storage, all in one, and fitting under a case.

I had that exact thought about two hours ago. Throw NFC in their while your at it.
Sent from my XT1034 using XDA Premium 4 mobile app

I had actually started to do some verrrry preliminary research into something like it using a ribbon cable and another usb port, so you could plug the phone into a wall charger and have the usb/sd card piggybacked off the cable. Hadn't gotten very far though...job, kid, wife etc.......
Someone TAKE MY MONEY for it!! Especially since it seems we're all soon to be headed down the 'no sd card' path.

I just got a Moto G for my wife and Nokia Wireless Charging Plate DT900 is not working any ideas why ?

It's not working with one of the universal QI receivers? Have you try enabling the floating charging (see my post)

Yes, you also need receiver in your phone.

Hello.
The Moto G doesn't support Qi on its own, you'll need to rig it with an universal wireless Qi charging receiver.
You can buy them from ebay, dealextreme and some other china based stores. The first post contains a short installation video.
This one from dealextreme will work (Output up to 650mA):

Setting to enable wireless charging?

Is there a setting I need to check to enable wireless charging on my Nexus 7 (2013)? I have 2 in my house and neither with charge with the Anker charger I bought. Whether in the case or out of it, it's not connecting. Not sure if I got a defective unit or if there is something I need to turn on on the device for it to work. Thanks!

Nope there shouldn't be a setting you need to enable to get wireless charging. It should just work right out of the box. Try moving it around on the pad and see if you can get a charge. Might be a defective unit.

No there isn't a setting, just place your N7 on the charger and your good to go. I use wireless charging on my N5 and N7 all the time.
EDIT: Make sure you put the wireless charger in the middle of the device for it to work.

Mine is a bit fussy about positioning on a Lugulake Qi charger. "x" marks the spot (the "x' in "Nexus" is where the receiver coil is located) and I have to slide it around a bit to get it properly centered. I don't use a case, but I suspect it charges more slowly with a case than without (greater separation).
Aside from those quibbles, wireless charging works just fine.

Anyone using wireless charging on the MI3? It's only possible with a receiver, btw, it's not built in.

I am curious has anyone tried using a wireless charging add on and know if it works properly?

I'm a writer for Qiwireless.com and I use my Mi3 with a universal wireless charging receiver to charge it.

I saw something here: facebook.com/MiuiCzechSlovakXiaomi/posts/10152284167068959
Manufacturer named Lencow doing this type of chargers for MI's. You can find the net for the price.

is it for real that mi3 supports wireless charging??

Note, WITH a receiver. A receiver is a piece of hardware which sits under the base of the phone, and is connected to the charging circuit. Just google the term.
You'd have to be really motivated to take your phone apart, just to attach that. Without considering the space that module would need vs the available space inside the phone, which is pretty slim to start with. Actually with a metal phone back, I believe the module would have to sit outside of the phone, between the plastic cover and the back - so the phone back would not be flat.
I have had a Nexus 4 with wireless charging for the last 2 years, and I rarely use the wireless charger I bought:
- charges slower than a wall charger
- if you pick the phone up - as we all do - you stop charging and additionally multiply the number of charging cycles.
Cables are not as cool as a Qi pad, but a Qi pad also needs its cable...
Anyway, out of the box, the mi3 doesn't do wireless charging - just confirmed that with my wireless charger

stupid!!! pls improve yourself bout the 'Electronic Science and Technology' knowledge~ don't ask such an idiot question!!!

Wireless charging

Hey guys,
Since the OPO has NFC I'm assuming wireless charging will work... What are some good and cheap wireless charging options?
Thanks!

NFC and wireless charging are two completely different things. You could add wireless charging via a universal QI receiver but that's it

Ohh didnt realize that! So would I just need a QI receiver and I can put my phone on it? Or do I need a special case for my phone?

You need a wireless charger receiver, you will lose the USB port, when you want to use USB you will have to take the case off and take the charger plug out.
Since it's pretty thin you can use any case, or none (Maybe not metal cases).
You also need a wireless sender, this is the pad that the phone sits on.
Notes: Since these are only 500ma (have not found a pad > 500) and with less efficiency (so its actually less than 500ma), it will take a very long time to charge the phone. I dont even know if its able to keep up with the power requirements of the phone if it's in use.

Powerbot chargers are supposed to put out 1000mah. I think its partially dependent on the actual charging cord plugged into the qi charger though

that is true. all parts need to be compatible to get a decent charge rate. i had a charger that put out 2amps and a cord that supported it too but most receivers put out 500-750mah which results in a slow charge. and i havent found a decent receiver yet either. Most of them are really finicky and need to have the phone placed just right on the receiver for it to charge.
