The only legit fast chargers I've found were the free ones that came with Motorola bluetooth headsets. But the wires would fray after a few months.
I see many 2.1A chargers online but only for Apple devices. I'm having a hard time figuring out which chargers deliver 2.1A to Android devices, Nexus 4 in this case.
Can someone point me to something that will deliver 2.1A to our N4s?
Thanks.

i have this charger under a different brand and can confirm it charges a bit faster than the motorola rapid charger(mine broke too). You can get this same charger under the powergen or mediabride brand.
also 2.1 amp chargers are usually specifically designed for the ipad and will not work well with android devices, it's just that this one has a 1amp socket that works well with android.
If I understand what you guys are implying, the Nexus 4 won't charge any different whether on a 2.1A or 1A output charger?
The Anker description says it will output 2.1A to an iPad and 1A to an Android device simultaneously.
It charges at 2.1a without an issue. Its older android phones that have problems with high speed charging. Nexus 4 charges very quickly with my car charger (Anker) and my home charger, 1.8a blackberry charger.
**this one is not specifically designed for the iPad. Its actually designed for android hence the microusb output. It just has an extra USB out that if connected to an iPad, can also charge it at 2.1a but if both devices are connected at the same time, it gives priority to the iPad. OP wants it for his nexus 4. No issue, it'll charge at 2.1a

no android phone can accept 2.1a, only tablets specifically the ipad can accept this much current. 2.1a is the default current for the ipad. I've tried lots of 2.1a chargers and very few can actually deliver more than 6-700mA to an android phone.
this is the same as the mediabridge/powergen one just with a cable attached, the micro usb cord attach is coming from the 1a socket. If you plug a micro usb into the 2.1a socket you will get the same current(probable less since that socket is designed for the ipad) as the attached cable.
the fastest rate is 800 or 900 mA for the nexus 4 with the factory adapter. you can check using battery monitor widget. i have the ankor charger(mediabridge version) and it gives about the same current as the factory adapter.
Hey Neo,
You're right. I downloaded "current widget" and see that it maxes out at a little over 800mA.
Learned something new today..
For all those interested, this post summarizes the different charging modes for the Nexus 4:

Does anyone know where to get a good 1piece wall charger with a longer cord. Or maybe even a good data/charging cable that can handle higher amps of our chargers. I'm looking for something longer than the small cord they gave us with ours phones charger. I know that not call cables are created equally though.

get the monoprice 28/24AWG 6ft cable. It will still charge a bit slower than the factory cable since it's so much longer but it's better than most other cables.

I bought a 10ft usb extender cable. My girlfriend is is love with it. Adds resistance so it'll charge slower than the normal plug, but it's good for when you sleep or are doing stuff around the house. Best $4 ever spent lol.

This car charger freaking rocks. It charged my N4 in 1 1/2 hours from 2% to 100% I highly recommend it. I never thought ID ever find a car charger that's faster than my old Motorola rapid charge but this charger takes the cake. Plus it has an extra usb port so I can charge my N7 or another phone at the same time and its a 3.1 amp charger to plenty of juice.

I use Avantek for my Nexus 4 and my iPad. Dual USB ports with one 1.0A and another 2.1A. Dunno if the specs were right but it does give full charge to my N4 when I'm using the navigation app.

Any idea why I can't seem to charge my Nexus 7 with my car charger?
i have both a generic Micro USB charger and I have one of the dual USB ports that you put into the cigarette lighter. It wont even acknowledge that I have plugged anything into it.
i have used the USB port to charge MANY different cell phones my old Dell Streak 7 and even a friends iPad.
Any ideas?

I think the N7 needs 2A to charge. a single USB is 500 mA and the dual 1A, so I don't think there's enough power.
Also check if the output of your microUSB cigarette charger is 2A

This one will work: http://www.amazon.com/gp/product/B0090SVY3K/ref=oh_details_o02_s00_i00
It charges at the same rate as the stock AC charger.
The N7 is one picky device for charging. I have several chargers for the car that charge the iPad but not one will charge the N7. Same as AC chargers. This set works for me

This is what I use and it works just fine. I use it to charge my N7, GNote, Nook Color or my grandsons IPhone and it works equally well on all of them.
BTW, it prime available if you are a member.

It only charges via usb when the screen is off or when the device is off. Try plugging it in checking the battery % leave it awhile and then recheck the battery % you may find its gone up!

Unfortunately I left my Nexus 7 charger in a hotel room a month ago and it has not yet been handed in. Consequently I have had to buy an off the shelf charger. One I tried stated that it was rated at 2 AMPS, and it does work, but at about 1.5-2x the charging time as the stock charger. I also noted that when using that charger the Nexus system did not say it was charging, although it obviously was.
I just obtained another charger rated at 2.5 AMPS and it performs exactly as the stock charger. Has anyone else noted this - that if the charger outputs less than 2 AMPS the Nexus 7 does not notify the use that it is charging and does so at a much slower rate?
Larry
My understanding - the charger has to let the device know it supports high current mode. Otherwise the Nexus limits it to 500 ma, which is correct for a cable plugged into a computer.

This is true; the same method applies to samsung chargers. There has to be 5v on one of the data lines as well to let the device now it should change to high-power mode.
Search for a tutorial on what to solder together inside of the charger or buy an official samsung charger of at least 1A (I believe Galaxy S2 chargers have that output).
Has anyone found a dual car charger for two Nexus 4's or a Nexus 4 and a Nexus 10 whilst in use?
Most dual car chargers seem to have one output to charge Apple devices at 2A plus another output to charge non-apple devices at 1A which is not what I need.
Thanks
I've managed to find something but it seems to be unavailable in the UK

Monoprice has plenty of these. I love their products and pricing.
It might be possible to charge two Nexus 10 tablets or two Nexus 4 phones using a dual iPad charger and power USB cables as described in the first link below.
The second and third links are items from Amazon which might work.

Have you tried to charge your nexus 4/10 with a 2.1a apple USB port? I tried it with both my nexus 4 and 7 and they do not deliver more than 1a. I just ordered the powergen dual USB. It will only give 1a to android devices according to the guys at the nexus 7 forums. 1a is enough to slowly charge my nexus 7 in the car with maps running but im not sure about the nexus 10. We need a car charger specifically made for android tablets that can output more than one amp but I don't know if there are any on the market yet.

If you read the article in my first link above then that says that a dual iPad charger with the correct cable should deliver 2.1A.
Here are some Amazon customer reviews showing that a dual iPad charger can charge a Nexus device at 2.1A when using the correct USB charger cable.

Unless someone tested it with the nexus 7 or 10 im still skeptical. Anytime you see the 2.1a it's designed for the Ipad. Just read that article and it doesn't say anything about android tablets just ipads. Im sure they do output 2.1a but just to ipads, android devices will only get 1a.
Sorry for offtopic a bit but is it okay to use 2A to charge the N4?
I mean does it kill the battery faster or it is totally fine?
THanks

i just read the reviews, just because it shows AC charging it does not mean its output is 2.1a. AC charging just means that its using a charger or cable that has the D+/- pins shorted. I have a moto 700mah car charger that shows AC to both my nexus 4/7 but only delivers around 6-700 mah. What im saying is that it probably wont output more than 1a to an android device. 1a is more than enough to charge a nexus 4(or any other android phone) with nav on but is a bit too slow for tablets. If you do get this car charger let us know if it does output more than 1a. you can use current widget app to find out how much current the phone is receiving from the charger. Im still looking for a car charger that can deliver more than 1a to an android device.

yes it's fine. The nexus 4 will not draw more current than is safe for the battery.

Thanks for your reply. I've ordered the charger and the USB power cable and I'll report back.
I use this
http://www.myinnergie.com/mCubeDC10/Default.aspx
Bought it when I had an iPhone and it could charge it and an iPad at the same time.
Now I use it with the SGS3 and the Nexus 7, works fine for both and they pick it up as AC.

Okay, let me start off by saying that I am complete noob when it comes to electrical matters, so excuse the silly question here...
I have found a USB powered QI charger for the Nexus 4 on eBay with an input of 5V and an output of 5V/1A. Two questions following from that...
1) Will the charge time be the same as if I just charged via USB?
2) Instead of connecting the USB end to my PC, could I not connect it to supplied Nexus 4 wall charger? If so, does it specs comply with those of the QI charger I just mentioned (i.e. will I get a fast charge time?)
Thanks in advance for the support.

Expect the charge times to be more compared to the Usb charger.. It can be ordered on fasttech.com for $40. Yes.. usb powered.. The AC adapter one on fasttech is $35.. All hav free shipping!!!!!
ii) That would depend on how much power the wireless charger needs.. The normal nexus 4 adapter is 1.2A.. If the wireless charger wants 1.5A, it will be slower due to less power... but since it is USB powered.. normal pc/laptop usb ports give 0.5A so your original nexus 4 adapter will be fine!!!!
Also.. wirless charging tends to heat up the phone sometimes.. so watch your temps..
I have the Energizer Qi charger and they warn that the Nexus supplied wall charger should not be used to power the WiFi charger. It doesn't have the power capacity to run the wireless charger.

The cahrging rate is almost the same
The power requirment for this charger is 5v 2A input. According to my test, as long as your power supply stay above 1A output, you will have no problem at all, just will charge a little bit slower. but once I hooked up with a samsung charger that was rated at 700ma, the red light goes on after a beep. The problem is, most of the usb chargers in the market are overrated that's why you will get red light on with these inferior charger. I purchased mine from a seller on eBay called gadgetsalon who included a original HP Touchpad adapter with my purchase which is fully rated 2A output, I have been using mine for almost 2 months now never had a single problem ever with my Tmobile GS3. BTW, I charge my phone with a ballistic case on all the time.

Self explanatory really. I realise any micro USB charger will fit, but I've read that of the voltage / amperage doesn't match, it can fry the phone. How true that is I don't know, but I don't want to risk it. I asked LG, and they directed me to their spares and accessories website. Initially it looked promising, but it turned out the website was terrible, was no info about anything.
I've had a look to find other 5V 1.2a (the specs of the charger that comes with the phone) micro USB chargers, but not had much luck. Any chance anyone could send me a link to a charger that matches the nexus charger? That would be very much appreciated.
Sent from my Nexus 4 using xda app-developers app
I read something that said if you use a charger with a higher amp, that won't cause any problems at all. Is that true? So I could use a 5V 2a charger with the nexus 4 (the original charger was 5v 1.2a)?
The reason I'm so concerned is that when I use my HTC Desire charger (5v 1a), the screen stops working properly. I used it all the time when I first got my phone and the battery in the phone died, and I had to get it replaced. I don't want that to happen again, so I don't want to use a charger with different amp output.

Yes, that's true. The phone will only draw the current that it needs. A 2A charger won't "push" the whole 2A to the phone, the phone will just "pull" the 0.8A or so that it needs.

Exactly. The amperage rating is what the charger can output based on demand of its load.
