Dual Nexus 4 or Nexus 4/10 Car Charger

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.

We can only use the LG charger?

Since the battery life of the phone is quite poor it's only natural that i would like to charge it when i'm on class or with an usb cable when im using my laptop, using other usb chargers/cables, but on the manual says (of course) that we should only use it with the lg charger that comes in the box or an official nexus 4 charger .
It kinda sounds like bullsh*t until i remember what happened with my motorola milestone, sometimes when i used another charger the screen started doing crazy things, like swipping the homescreens by itself , oppening apps, until i charged it for at least a few minutes with the official charger, some months later my digitalizer died, so you can imagine how traumatized i am, but then i think what's the point of trying to make a standard out of microusb chargers if we can only use the official charger? what do you guys think?

I find battery life to be very good.
I have been using an old HTC charger on mine without issue though. I suspect the 'only use LG charger' is to cover themselves in case you kill the device with a cheap and badly made knock off.

AW: We can only use the LG charger?
I have literally problems in draining my battery, running Franco's Kernel and Minco v6.
Anyway, using another charger should be no problem. I used the charger of my Asus Transformer and a mobile charger in my car without issues.

Feel free to use any USB wallcharger you'll find.
I tried some i had laying around (HTC, iPhone 5, iPad) and they all charged without trouble.. :good:

Yeah, I've used a 1A HTC charger with no issue. I accidentally left my lg charger at a friends house and had to use what I had.

the battery life is good, better than s2 with its extended battery, i was wondering about this too as i want to use a sony rx100 at 2amps to charge while im traveling.
on page 168 of the service manual it states the max charging current is set at 900mah, over voltage protection upto 28volts

The current should be controlled by the phone, not the charger. Therefore there shouldn't be a problem with more powerful chargers. The voltage has to be correct, though

The phone certainly regulates the power it takes.
If you are really worried about the chargers just flip them over and read the output ratings. Most of them are exactly the same these days.

P.s- the battery life on this device is outstanding, you just need to find the kernel that works well on your device

Any USB charger will work. Note the output current on the charger though, as that will impact how fast it can charge and whether or not you can have the screen on while you charge. The LG charger that comes with the phone is 5v 1.2a, an iPhone charger (at least as of the 4S when I got mine) is 5v 1a and an Amazon Kindle charger is 5v 0.85a. The USB 2.0 spec calls out a max power output of 5v 0.5a.

I'm confused , the lg nexus 4 charger is 5.0v 1.2A and my galaxy nexus charger which i use sometimes with my nexus 4 is 5.0V 1.0A , what does this mean? what's the difference?

My Nexus 4 is on the way so i cant comment on that but my Sony Xperia S acts differently to different USB leads even on the same charge unit. It might charge at 500mAh or 950mAh (on a charger rated at 850mAh), the screen might be fine or it might act erratic and it all depends on the lead plugged in to the charger

I used Samsung/blackberry chargers and they worked. Not sure if they were as efficient though.

I pretty much use anything but the LG charger and have been doing so over a month. So feel free to use any quality charger you like.
I also charge of my Philips Qi pad and off computer USB ports.
As long as it's providing stable power or anything close to it, it's good.
Just be careful with (fake) cheapo chargers. Those might cause issues with the touchscreen going haywire while charging off them. I've also read that about some car chargers, but so far my cheap 2A 2port USB car charger that came of DX is working fine for me.
YMMV of course. But there is no need to stick to just the LG charger.

[Q] Recharge time > 8 hours?

Hey all,
I've been using my N10 for a week now and am wondering why and if it's normal for the tablet to require 8+ hours to recharge?
I'm plugging it into the wall using a generic USB cable and non-Samsung power block. Should that matter at all?
Signed 'confused...'

Yes, the charger matters. The stock wall charger is at 2Amps, while a normal USB connection is at 0.5Amps, for example. All devices will charge more slowly on lower amperages, but since the battery of the Nexus 10 is so huge (9000mAh - about double your average laptop), charging it from 0 to 100 will be dreadfully slow, if you're not using a proper charger.

1. Are there other wall chargers with higher Amp output that are safe to use w/ the N10?
2. Is there any long term damage to the battery using a higher or lower Amp charger?

Another issue is if the charger is made for an Apple product it doesn't short the data pins so the Nexus doesn't see it as a high amperage power supply and only pulls .5 amps.
Use the OEM Samsung charger or get one of these:

And if you want a it to charge even faster, use a pogo cable.

Higher than 2.1 amps? Not commercially that I'm aware of, though you could always jerry rig some contraption to deliver more.
The problem is, however, that the device will not draw the extra power. A device will draw the power it can use, and no more. I haven't tested what the draw is on my Nexus 10, but on my Note 2, it never draws more than 1.8 amps (although that reading may be a little inflated and it really only draws 1.5 amps). I suspect it's more or less the same with the N10 and the stock USB cable and Samsung 2.0 amp charger. So if you went nuts and jerry rigged a 50 amp power supply to the device, it would still only draw 1.5 amps.
Note that the draw can be affected by the USB cable you use. I've seen some USB cables draw less than 500mA where the stock Samsung USB cable draws 1.8 amps.
Bottom line is that you're not going to find a wall charger above 2.1 amps as far as I know, and even if you did, it wouldn't charge the Nexus 10 any faster. The problem is what you identified in your original post -- using some plain vanilla 500mA (0.5 amp) micro USB charger that you've had lying around the house for the past several years and assuming that it should charge just as well as the stock Samsung charger. It won't, as you discovered -- the N10 will only draw about a third of what it's capable of drawing from such a charger.
Be careful buying 2.0/2.1 amp chargers from Amazon or wherever, particularly if they're identified as Samsung chargers. They're almost always counterfeit, and no better than the 500mA chargers I mentioned above.
You might also want to look into the POGO charger cable because it allows the Nexus 10 to draw virtually the full 2.0 amps from the charger rather than 1.5.

Listen to this guy.

@JasW - Wow, thanks for the information / education. It makes a LOT more sense now.
Thanks again, F

@Gearhead_ENG - Thanks for the links! I'm going to go home and scrounge through all my old chargers and see if I have more 2Amp chargers. If not, I'll be following the links again to purchase...

Where can I buy a new charger at?

I don't see a charger from evga on newegg or on their site. Third party suggestions welcome if necessary. Thanks in advance.

My factory charger is rated at 2 amps @ 5V so any charger with those specs should work. I use my Amazon 2A charger without any problems as well as the 2A port on my Ravpower portable battery pack.

TLDR: You get what you pay for. Any 5V charger will charge the device, you do not need a specific "Tegra Note Charger". The larger the current rating the quicker the device will charge. If the psu does not have a USB port in which you can plug in a USB>MicroUSB cable, ensure that the psu has a microUSB plug attached.
There are two main considerations though besides this, first is brand/quality, the second is the charge current available.
Brand/quality - Not all chargers are made equal. Most nowadays are switchmode but component quality and design will vary greatly between chargers of different brands. Whilst the basic buck design that most manufacturers will use is efficient, there is a lot of transient noise introduced as well as voltage ripple depending on the design and components used. The funny thing is that the difference between a "good" psu and a "bad" psu is cents in the dollar but many manufacturers will choose to save those cents. The sense behind it? Most consumers are completely ignorant.
Charge Current - There are two main differences you will see between a 500mA or 2A charger. The first is charge time - if the psu is capable of supplying a higher charge current and the device is capable of drawing that larger charge current then your device will charge quicker. Thing is though, the USB standard requires negotiation to be made between the psu and the device for charge currents larger than 500mA. If you buy a cheap psu that is capable of 2A but does not have the negotiation IC, you will never charge more than 500mA. Once again, the difference between having this IC and not is cents in the dollar.

I just bought some US->Euro AC-adapters so i can use the original charger. A new charger that has decent quality would cost at least 15$ or more, since 2 ampere outputs are rather uncommon (most phones-chargers ones only have 1 ampere).
And 1 ampere is not quite enough to charge the TN7 an use it at the same time (currently using a 1A-charger).
But even with those adapter you don't want the cheapest. Or at least read some comments on amazon before buying. There are a lot of really cheap ones.
I got these ones from amazon and i really hope they're the better ones ...

Turns out the Nexus 6P can be charged via Quick Charge afterall

It was disappointing to find that the new Nexus devices don't support Qualcomm's Quick Charge 2.0. I would have thought after all of the demand, especially with the Nexus 5 that Google would make it a requirement. So I saw this article on Droid-life and thought I should share as a general PSA to everyone. They did tests and found that the only quick/rapid charger that can charger nearly as well as the more pricey stock charger is Tronsmart's Type C car charger.
Unfortunately I can't post as links as I've been a lurker for too long and not enough posts, but they have it over at droid-life if you want to check it out. Someone could probably even comment it for me.

http://www.droid-life.com/2015/10/19/nexus-6p-nexus-5x-quick-charge/

Except it charges at about half the speed of the dedicated 15W/3A USB-C chargers.

I bought one of those tronsomart car chargers last week. Seemed like an adequate charger until I can get a suitable one that can supply 3A. The fact that it had a USB port so my wife can plug her iPhone into it sealed the deal. It's definitely going to be better for me than the car chargers we have now, that's for sure.

Get this. I've had 2 of them for a year or so and they charge my N6 faster than any QC2 charger I have. No usb c, so if you really want that you are SOL but I don't think that it will matter

I must be missing something? Down the bottom at Update 3 it says that the Tronsmart was almost equal to the stock charger and one of the tests has the stock at 2642mA and Tronsmart at 2511mA.
