Anyone use a Powermat to charge their phone? it looks like the usb attachment doesn't make it register like it's charging?
I have the same problem with USB charging. Neither my PC nor my Macbook Pro will charge the phone. It says charging, but the battery continues to drain. I noticed on my mac the USB port is only providing 500mA. The plug-in charger that came with the phone says 1.0 amp (1000ma).
I have a powermat too, but you need a special back cover on the phone to get it to charge this way, even that's even going to be an option on this phone.
having an issue with some of my car chargers too, some work some don't.

I initially had problems when using the power cube as well. This was a little surprising since its output was 1A which was the same as chargers which worked well. I decided to try using a different mini to micro usb adapter than the one which comes with the power cube. Once I switched adapters, the powermat worked perfectly.
Any particular model?

You would ask that. I found the packaging and it's an Adapti. It's just a cheap adapter that I bought from the local Fred Meyer (a department store chain in the Pacific Northwest) about a year and a half ago. It also came a mini-usb to iPhone adapter.
Hopefully this helps. You should be able to find an adapter that works.

Hey guys,
So I made this rather funny discovery (not surprising though). I have an OTG cable for my Gnex to read USBs, out of curiosity, I plugged in my USB data cable for a Galaxy tab 7 (P1000).
Since this tablet doesn't really have USB host functionality (unless I have like 300 cables and a power source), my Gnex was charging my Gtab :\
If I were to get a new tablet (which I plan to later), could I choose which device to charge which device? Say e.g I want to charge my phone using my tablets power. I ask this since newer tablets have host functionality.
Thanks
Bwahahaha. I have visions of a short guy bringing a tall guy a ladder.

it's not going to work, you can't output power through MHL or host(im pretty sure) and besides the voltage would be to messed up to charge. so no.

OK.JPEG
I see your point, the charge provided by USB host wouldn't be that high anyway...
Would be a cool function to have though right? I've been caught in situations where I wish my tablet could charge my phone ...

Yes you can output current through OTG, so it is not a wonder that you can charge your tablet. Otherwise you could not even use any memory sticks and such.

Every night i charge my Galaxy Nexus using my Motorola Xoom.
I have my Xoom plugged into the wall charger --> my USB Host cable plugged into my Xoom --> my USB-MicroUSB cable plugged into my Galaxy Nexus.

I doubt the GNex can output enough power to charge the huge tablet battery at anything but painfully slow 1% per hour process.

Moreover, the Xoom cannot be charged through USB...
But I like the idea to charge the GNex through the tablet. It's got quite a large battery. Two actually.

The other way around works just fine with my XOOM. My XOOM can charge my old N1 and my new GNEX just fine... XOOM has like 3 times the battery...
Seems like that any new tablet I get then would be able to charge my phone then
I won't be charging my tablet much, most likely tablet charging the phone e like you guys have mentioned!

I own a N7 2012 and hated its short and stiff cable.
If I use other cables, it won't charge as fast or at all.
Does N7 2013 has the same problem?
Not a nexus problem anyway. The cable and charger declare themselves as high current - or they don't. If you use a charger and cable that don't meet that standard, you will be limited to 500ma. A lot of cheap Chinese cables can't carry more than 500ma anyway. Cut them in half - you won't see any copper.

My 2012 N7 DESTROYED microUSB connectors. It would bend the catches down in the cable connector. It worked fine at first, but after a few days of using it, the cable wouldn't stay in because it had pushed the spring loaded clasp down to the point it wouldn't come up. Also, why does Asus put the connectors upside down from EVERY OTHER MANUFACTURER? So annoying. I was trying to make a bluetooth speaker with a charging dock in it, but I can't use my N4, GS3 AND Nexus 7 because the N4 and GS3 have the port oriented one way, and the Nexus 7 is oriented the other way.
Part of the problem is that iphone/ipad chargers don't require the same configuration to be in a high-amp charge state, whereas micro-USB requires the proper connections to be in the proper charge state. I have some chargers for iphone/ipad that will not even show charging for Nexus 7 2012. Original Apple or not.
What is a good app to monitor the output from my charger? Or does stock have a built in feature? I feel like my Nexus 7 charges REALLY slow. I just dropped 10% while playing a game and charging for about 40 minutes, maybe that is normal? I may just be spoiled because of a certain other tablet that charges quit quickly.

Because of the nature of how devices charge, measuring the current via an app is very unreliable. The only app I have found that works at all on the 2012 nexus was https://play.google.com/store/apps/details?id=com.promethyl.batterychargingsourcecurrent . Not sure if it works on 2013, but its free

I've always wondered this. It's quite odd.
To answer the question, absolutely not. It is a charge whore just like my Galaxy Nexus. I've used iPhone chargers at 500ma all the way up to 2.1A chargers. The N7 was picky but the new one is not. It even charges off my car charger now which the first one would never accept... even after I modded it to do a fast charge on my Galaxy Nexus.
So yea, I haven't found one USB charger that it wouldn't gobble up.

I just got an S3, and was excited about the ability to use wireless charging. While looking for QI gear on eBay, I ironically stumbled across an item that will add that very same feature on my old SII, without any permanent hardware mod needed.
The item in question is this: http://www.ebay.com/itm/200963522572?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
It's basically a QI charging inlay thing that has a very tiny microUSB connector, allowing you to connect it to essentially anything that charges via microUSB. I bought one just to try it out, and sure enough, it works like a charm with my old S II. I have a cheap (but great) TPU case on my S II, and the QI inlay fit absolutely perfectly between the case and the phone's actual back cover.
I used the SII for more than a year and a half, and I frankly hope that this was just invented a few weeks ago, as I hate to think that wireless charging for my S II was $16 away all that time >.<
Hey, *thanks* so much for this, it is just about exactly what i was looking for (and not able to track down on the net). Much appreciated and can't wait to try it out on my SGS2!

With "Android Tuner Free" you can see the incoming mAh when charging (at battery stats).
With standard wallcharger from samsung I get ~640mAh
Does anybody got the incoming mAh stats about wireless charging?
Anyway, I think cable is better because you can move and use your phone.

Hi
Didn't think of this before I bought it.. But I've just received a QI charger from Amazon.
Which charger do I used with it?
The one from my nexus 5 or the one from the nexus 7 2013?
Ideally I want to be able to charge either device.
The QI states 5v 1500ma input.
Also what's the best app to monitor the charging, time, input heat etc?
Thanks

Did your qi charger not come with a mains power adapter.
I can't say for the nexus 7 but the nexus 5 comes with a 5v 1200ma charger so it won't be able to supply the current that your qi pad needs.
Have a look on your nexus 7 power brick. It will tell you what it outputs.
Nexus 5
Input : 100-240V
50/60hz 0.2A
Output : 5.0V 1.2A

what brand? you can try plugging it in your laptop. mine (Nillkin) says Input: 5V/2A but it still works just fine if i plug it in the laptop.
otherwise I use the Nexus 5 charger. I think it's just the maximum your charger can handle.
You can use any USB power source... What varies is charge rate. I picked up a 2amp supply from amazon. You have to figure in less than 70% efficiency... Especially taking into account non laboratory ideal conditions and manufacturing...
1 amp input will be like slow charging from a computer at best. 2 amp will be on par with regular wall charging if not better. You always want an adapter that is above what the charger can handle to make full use of the charger... Lower ones will still let it work to lesser and lesser degrees till it doesn't charge the device depending on supply and device needs

It can be used with either the Nexus 5 or Nexus 7 AC Adapters. The Nexus 5 is 1.2A and the Nexus 7 (2013) is 1.35A I believe. Neither will fully power the Qi charger, but it will still be enough to make it work. The charging time for your phone will just be longer since the Qi charger is not being provided full power, so the current the Qi charger can provide to the phone will also be lower. If you want your Qi charger to operate at full efficiency/power, try to use an AC adapter that is 1.5A or higher.
Since your Qi charger only requires 1.5A, the Nexus 7 AC adapter is the closest, so I would recommend using that one.
In the future though, you might want to consider buying a higher output AC adapter:
The Blackberry Folding Blade Charger is 1.8A output, and microUSB, so you can plug it directly into your Qi charger (or phone if you ever need to charge you phone at rocket speed!):

The Boxwave Fast microUSB charger provides 2A output, microUSB as well, so if you ever buy another Qi charger it would be good, as many Qi chargers require 2A input.

You could also just buy an adapter similar to the Nexus 5/7 without the cord attached. For example, something like this.

I've tried my nexus 7 charger with the qi pad and ran battery monitor widget.
Tablet showed at -432ma, sat it on the qi pad and it changed to -124ma!!
Why a negative figure ? I assume I'm using more power than its charging.
Would a 5v 2a charger male much difference ?

Just had a thought the value I'm ready is when the screen is on, out it being off make any difference ?

Try using currentwidget (free) to read just the current being provided during charge.
Set it to update at 1 second intervals.
Even with the screen on, if you are not using navigation, streaming stuff, gaming, etc. it should charge even if it is not getting the full 1.5A current provided to it. It would just charge slower not discharge.

As I learned from another thread, the cable makes a significant difference. After using a 2a charger, current widget, and checking the charge of all my cables: 2 provided about 1.4a, a few 1.1a,and a large number of cables cut power down to 600 down to 300.
You need a capable 2a charger, a quality cable that you have actually tested, and a qi charger that accepts 2a and doesn't lose a majority when converting to induction.

You might have read that from one of my posts hahah.
I've said in different Qi charger threads to have a good 2A charger and to replace the included micro USB cable with higher quality cables (premium monoprice cables, or the Motorola Ecomoto)
I did a video demonstration on USB cable quality here. Didn't expect that drastic of a difference.

Hi.
I'm using a nexus 7 charger
1st models charger is 5v 2a
I've tried the following cables: included, nexus 5, nexus 7 (1st edition and 2013) and a couple of other cables.. All with very similar results.
Think I'll send this charger back and then with a recommended one.
