The Only Car Charger You Need for the Nexus 7

There are so many threads on car chargers that actually work for the Nexus 7 and yet none of them seem to have reliable answers. Maybe it works, maybe not. Does it do "AC charging"? Is the amperage high enough to keep it running while I use it? Do I have to short Data+ and Data-? Does it work with OEM or aftermarket cables? Is it expensive?
It's enough to make you just want to keep the Nexus in the house. So I'm here to help - just go buy this:

It's a 3.1A dual port car charger for $12.99 on Amazon with a full 5/5 review. I just got mine and it's well built, very sturdy (almost OEM quality) and has two USB ports, one for Apple devices "A" and one for non-Apple devices "NA". The "NA" port will charge the Nexus 7 and the "A" port will charge most other non-tablets, including the Galaxy Nexus. It works with the OEM Nexus 7 cable, a Monoprice cable and a Galaxy Nexus cable.
So that's it. Just go buy it and be happy. It will charge quickly if you leave the tablet off but will still charge it if you keep using it.
EDIT 2-11-13: This charger has been charging my Nexus 7 virtually every day (40 mins/day) for over 3 months now with no problems.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
For those of you wanting to know some more specifics, here they are. (You don't have to care, honest! Just go buy the thing.)
I did a test with my 7 starting at 40% battery. I did a "worst case scenario" of Wi-Fi on and connected, Bluetooth on, GPS on and using Google Navigation, Spotify streaming and the screen on at 100% brightness throughout charging. I powered the adapter off a variable DC power supply that shows current draw as well as voltage. I used 12.2 VDC to simulate a car's battery. Below is the relevant portion of the battery monitor graph.

It does indeed charge using the "NA" port with no modifications. The power supply showed an average current of 0.50A @ 12 VDC which once converted to 5 VDC is 1.22A not counting for the small loss in the DC-DC converter. It did get as high as 0.62A (1.51A @ 5VDC) but seemed to level out at 0.5A for the vast majority of charge time. (FYI I assume Watt's law applies here when stepping down voltage - feel free to correct me.)
I checked on the progress every 30 mins and here are the results:
00:00 - 40%
00:30 - 48% (+8%)
01:00 - 55% (+7%)
01:30 - 62% (+7%)
02:00 - 68% (+6%)
02:30 - 76% (+8%)
03:00 - 83% (+7%)
This is where I stopped. It seems to be very capable of providing a decent charge while under heavy use. At this point I turned everything off and waited another 30 mins and found it charged another 12% while "idle". At that rate it could charge from empty in around 4 hours. It would take around 7 hours to charge completely if being used heavily, but it's not just "maintaining" a charge or discharging slowly - it's actually gaining a charge.
So there you have it.

Powerful car chargers (2Aand above) usually affect your FM radio reception, how does that one go?

Sounds great!
I checked, and it's available on amazon.co.uk as well, here: http://www.amazon.co.uk/PowerGen-Ch...ZY/ref=sr_1_15?ie=UTF8&qid=1351432753&sr=8-15

What about the "A" port makes it exclusive to Apple devices only? I own zero Apple devices, so would this dual USB charger effectively be... a single one for my uses?

I think the "A" port does not short the two data pins because Apple doesn't like that. Most Android phones don't seem to care either way though. My Galaxy Nexus works with it, I think a friend's SGS3 works as well. A reviewer notes the Kindle products worked as well. The thing to note is that charging non-Apple devices in the "A" port will only charge them at USB speed. Not perfect but it should do the trick.

If you are rooted and have a kernel setting to enable fast charge on USB, you should be able to use the "A" port for full power. Be sure to turn that feature off, though if you want to swap data with PC.

I tried this on computer USB and the notation in Battery Monitor Widget changed from USB plugged to AC plugged when connected to my computer. milliamps went from 479 to 875. Still will see what happens on various chargers. But to get 875mA from computer's USB port seems pretty darn good.

Thanks a lot for sharing this with us! seriously there are many car chargers than would never work due to low amp!!

Bought this same charger the other day. Arrived yesterday, so far so good! Excellent value for money :good:

Good Deal On Amazon
Thank you for pointing the way about car chargers that work. I have been impressed with this charger doing more than slowing down discharge. I can actually use the larger GPS of my N7 and charge my tethering GS3 at the same time. When purchasing this charger I was offered the 3.1a/15w AC charger for 20% off. It definitely charges like the OEM one. Very happy camper.

What cord are you using with this to charge the nexus?

Another Option
Hey guys - there is another option that is very high quality -
The Scosche ReVIVE II works very well with the nexus 7 (at the same time as a phone too) with the 2.1A charging port. The only catch I found was that I had to short out the data connections - but I did this with a USB extension cable.
Essentially all you do is cut a USB extension cable, reconnect the power wires and then join the two data wires on the device end. This, for someone who has done some soldering, is a super easy job and takes 5 minutes, as well as making sure you don't ruin a perfectly good micro-USB charger.
The reason for shorting the Data is that some devices wont charge to their full potential (ie. only to 500mA) if they dont have the data wires shorted because the device might be connected to a computer - which wouldn't handle the full 1/2A.
anywho, it's a fantastic, very high quality charger and well worth the price.

Charging Cord
I use either my OEM GS3 or N7 for the NA port. I have a Rocketfish USB charging cord when I have to use the A port. I purchased it from BestBuy a while ago, initially for my BB at the time.

This sounds great.
I have a iPod Nano 6th Gen that I keep plugged in all the time, and a USB cable for my Phone. I modified my existing one so my Galaxy Nexus reads it as AC and charges fast, but my N7 doesn't even see it.
The one posted in the OP sounds like it'd be perfect. I could use the A for my iPod and the NA for both my N7 and GN. Fortunately the N7 doesn't require car charging very often

Sadly, Amazon.ca doesn't sell the charger and Amazon.com won't ship to Canada. Has anyone found a good source for this charger in Canada?

I just purchased the OEM battery with charging dock from Samsung with a 50% off coupon posted on this forum. Cost just under $30 bucks and the charging cable is 2 amps for certain, I checked the current while charging my phone with it. It cannot be used to plug into a usb port on a pc.

The thing is, I've gone through two OEM chargers now (One came with the phone, one bought on Amazon) and both no longer charge at 2A
In fact, the one that came with the phone has deteriorated so much it only charges at 160mA.

Looks like my original cable isn't charging the way it used to. The one that came with the external charging dock works better than the one that came with the phone.

Interesting. How do I check if my OEM cable has deteriorated for sure? Mine "feels" like it is getting slower for some reason.

so is there no true 2 amp cable? I'm not going to pay the extra money for the OEM one if its just going to deteriorate

I had trouble finding cables that I knew were reliable, so, I ended up fabricating my own. When purchasing new cables, they rarely mention what gauge wire they use. Most typical usb cables use 24/22ga. Some, like the oem use thicker gauge wire for the charge lines. The cables I made, easily handle 2 amps and thensome. I used the same wire that I use for my high powered LED light system which draws up to 6 amps without breaking a sweat. I know it is overkill, but I went with military-spec 18 gauge wire, stranded, silver tinned copper with teflon jacket. I bought new connectors, usb-a and micro-usb from overseas as I could not find them locally. After soldering, I filled each connector with an epoxy resin to eliminate all vibration and make the plug all one solid unit. I rarely actually use cables for data, so, I made them strictly for charging. Using only two wires also made is easier for me to use the thicker gauge. I bridged the data ports within the micro-usb plug. I have a non-samsung usb car charger that never charges some of my other phones at full rate unless the data ports are bridged. I made an inline adapter for the purpose that I used for a while. Making my own cables gave me the perfect opportunity to bridge them internally and eliminate the adapter. Certain phones need the data ports bridged or else they will think they are hooked up to a computer and limit charging to 700 milliamps, give or take. Hope you find the cable to suit your needs.....

There have been quite a few posts with links to cables that seem to work fine for others. I would be willing to sell some cables, if there was enough of a demand for them, however, to be honest I think there are many other viable, more inexpensive options. I could never sell them for what some of these other cables are going for that are mass produced. I put a lot of thought, time and work into these. The mil-spec wire alone that I use could buy you a few sets of other cables. I purchase the connectors in bulk and the first batches have been accounted for. Also, I am backed up doing so many other different mods at the moment that cables are at the bottom of the list. I'll try to post some pics soon. If, after that you decide you'd still like one, we can go from there.....

I bough an OEM samsung note 2 charger and a couple of days ago it stopped charging like it used it. It goes much much slower.

Just a heads up
You can find these at Wagreens usually around the register areas. They aren't the best looking but they charge my Note 2 and Nexus 7, which both require a 2A charge, very quickly. I can get from a 30% back to 100% in less than an hour on these bad boys.
Ive ordered several micro USB cords on Amazon and they either don't work at all or charge my phone very slowly. Even ones that have claimed to be OEM samsung, they finally show up and they're not. So far these are the only ones I have found that truly work with 2A chargers
One side of the "Y" is micro USB and the other is mini USB

How I fixed slow charging

A lot of us have the slow charging problem. I'm pretty sure it's a hardware problem and the micro USB port isn't the highest quality and suffers from wear and tear. I've already replaced one and was going to have to do a second.
Instead, I've come up with a brute force solution that seems to be working. Whether it's hardware or software or green aliens, I simply increased the current flow by increasing the voltage. I bought a 5.6V 2A generic charger off eBay and wired a micro USB charger cable to it. Just two wires, +ve and -ve. Seems to be working. I tried 6V but the tablet rejected it.
It's not perfect but I can charge the tablet in about 4-5 hours, as opposed to 2 days. I'll post updates if anyone is interested.

I too have this problem, but i really didn't notice it till i had to go on a trip a friend and was gone 4 days. the tablet was on, but asleep.
When i got back the tablet was dead. it seemed to take over a full day of charging to get it back to full. Then a couple of days later i had got my Y charger adapter. i installed it, and added a USB stick for more storage.
I found out the next day i had to go out of town again, but i was going to drive this time. After being on the road a few hours playing videos, i noticed my tablet using more power than it was charging. So i removed the Y thinking it was faulty even tho it showed it was charging. I still had a slow charging problem with it removed.
I would like to know if this did indeed fix your issue.

It's not perfect but it will at least maintain battery whilst gaming with brightness up. Charging when off is WAY quicker than a standard 5V charger

Probably 99.9% of android devices will expect shorted data pins, which is supposed to be the USB charging port standard. There are manufacturers that deviate slightly from this. For example Samsung adds 1.2volts to the data pins to signal that it's connected to a Samnsung charger and try to pull more amps (mostly for their early tablets). With the the S4 they added another signal voltage for their new 2 amp charger.

Now for my point. My Nexus7, and S3 use the smb347 management IC (maybe the S4 too). It is picky when it comes to input voltage, and in the case of the Nexus7 it was programmed to be EXTRA picky. The USB standard port voltage is 5.0 ±0.25, while I believe a USB3 dedicated charging port raised this to 5.3volts. I would personally not follow LeighR advice and set up a supply to feed my devices with over 5.4volts.
If I was you I would look for chargers with a voltage under load of atleast 5.2. Use a multimeter to measure, I love the ChargerDoctor, but they used cheap connectors it drops a lot of voltage on top of the parasitic usage.

weedy2887, my issue is that my tablet is a permanent install in a car, so i must use 12V-DC.
I have a 5.0V charger plugged into a cigarette lighter, and using the factory USB cable that can be plugged into an AC or DC connector.
Any suggestions for a fixed car mount?

Weedy2887 is correct that over voltage is of course a potential danger to your device. However, if the voltage is too high, your tablet/phone will reject it.
The voltmeter idea looks great but the problem is with the N7 microUSB connector. So you could be supplying 5.3 volts but high resistance due to a poor connection will drop some voltage and the potential difference actually reaching the battery will be lower, hence the slow charge.
He is of course correct that if your tablet is NOT faulty, it is not a good idea to hit it with a high voltage.
I like the idea of a smart charger - is it a constant current generator? Or does it detect current drawn and vary voltage accordingly? That would be an excellent solution. In any case, some great info posted, thanks.
Regarding the car installation, if your tablet has the super slow charging problem and you want to copy my solution, you'll need to find an in-car charger that puts out 5 and a bit volts and then wire on a micro USB connector.

Being permanently installed changes nothing. You still need to pick a better supply.
Something adjustable, and then buy a micro usb plug:

or a better cig converter:

I dislike the idea of relying on the device to reject over voltage, it just feels dirty to me. And your point about connector losses is interesting. You could calibrate the charger with the tablet open and a multimeter on the solder behind the socket.
The "smart" part of the charger is it can detect what the client device is and setup the right pin out on the plug. IE: Apple, Android, HTC, or Samsung.

All very valid points. Agreed

What i'm using now says it is a 5 amp.

This fixed the N7 I had. Takes about twenty minutes. Carefully pop the battery out, take out some screws to get access to the ribbon cable contact at the bottom, clean it and reconnect. Clean the top contact too by the battery plug.
It's not the usb port it's those damn little contacts on the ribbon cable.

In your case it was the ribbon cable. And you're right, it could be for other people too. But in other cases it's a worn microusb port or other issues.

Watts are not amps.
It's probably wired for Apple.
It doesn't matter what the side of it says it will put out.
The only thing that matters is what the tablet THINKS it can pull. After that is all down to the voltage level it will sustain under load.

This method works for me, although not perfect. From frustratingly long 22 hour charge time down to 6 hours on 1.5amp charger

While the improvement is great, your still charging in USB mode.
The tablet will charge in a little over 2 hours if it's pulling over an amp from a charger.

Choetech C to C 3A/5V wall charger

I received this from Choetech a few weeks ago at a discount for an honest review. We have both a 5X and 6P in the house, so having an extra charger for work was a must but there weren't really any options other than the Google Store. I like this one better because the cable is not fixed, so I can use any cable I want with it. Paired with the Choetech 1m C to C cable this thing performs just as fast as the stock 5X and 6P chargers, topping out at around 2700-2800mAh on Ampere when my battery is around 10-15%. Build quality is excellent and I like that it has the plug on the end of the charger like the stock Huawei charger, not the side like the LG charger. THe cable itself (sold separately) is well built also; some of the other third party ones I've tried are too thick but this one is just the right balance of thick without being overkill. Another big bonus with the cable is that they come in 0.5m/1m/2m/3m lengths so there is something for everyone. I've purchased Choetech products before for my Nexus 5 and 6 and have been very happy. Overall this is a solid combo and I will likely be ordering another one or two so we have some extras around the house/work!

Glad to know it works well for you. I've had bad experience with the longevity of the two Choetech products I bought in the past, neither work anymore so I probably wouldn't buy from them again.

Too bad they dont make a EU version of the wall plug

Bought the following:
USB C to USB C
USB A to USB C
USB C charger
I have tested the USB A to USB C with CheckR/Nexus 6P and it passed. I rarely transfer any data using USB these days, so I am only look for charging. These are great accessories for these prices.

I also have this charger and cable from Choetech. My only (minor) gripe is that this combo takes an hour longer than the factory charger to fully charge my dead phone. I only plan on using this as a spare, so no big deal. The build quality appears to be very good, so we'll see how it holds up over time.
I also have the Choetech type A to C cable, which also works very well. I was initially concerned about Benson Leung's review of this cable and how it did not meet Type C spec. After reaching out to Choetech customer support, they quickly responded and sent me a revised cable this is within spec. I tested the cable with CheckR, and it did pass the test. Choetech's customer service has been great.

Using ampere, I find that the Google stock C->C and choetech c->c cable both charge near the same rate
I like the quality of the CHOETECH cables, this is the first time I've received them. They seem like they're very strong as they are very thick. I get a max 2.4A using the a->C cable

I also have this Cable and charger from Cheotech. To date I do not have any complaints about it and it seems to be working well. Like you stated, it does indeed charge at the same rate of the Google stock charger/cable. For the price, I would recommend it.

I just recently received the choetech c to c cable and the adapter, I think it charges about as fast as the factory charger does. Even if it is a bit slower for anyone, it's still way faster than what we would have without type c, so good enough to me.
The cables do seem to have good build quality, and with my usage of cables, I think they'll probably last pretty well. I've never really had problems with any cables from anywhere before though. But these cables are cheap too, which is nice with how expensive other cables can be. I'm probably gonna use the c to c cable for a car charger I recently bought, and then the adapter is a really nice backup adapter to keep around.

something seems wrong, like I said this charges at the same rate as the stock chargers for my 6p and 5x, and everyone else who has chimed in here and in the 6p thread has said the same thing. you might have a bum charger?

That could be the case. It took 2.5 hours to fully charge my dead 5x, and my phone was not being used during the charging period. That's definitely slower than the stock charger for me.

I received this cable and charger from Choetech a few weeks ago at a discount for an honest review as well.
Like others have indicated above it charges at the same rate as the 5x stock charger for me as well. Quality of both the charger and the cable is good. I keep this charger and cable plugged in on the opposite side of the house from my stock charger and cable. I also plan on taking it along when we travel so I have the convenience of fast charging.
It's nice to have a modestly priced product available that can offer the same charging speed as the stock charger.

[Review] Choetech 10W Wireless charger, and 60W 6 Port charging hub review

Note: I will keep this OP updated if any issues arise, and add in more observations over time.
Choetech 60W 6 Port Quick Charge 2.0 Hub: This charger was given to me for free in exchange for a fair and honest review
Packaging:
When it comes to buying items the first impression is key, and that’s where the packaging comes into play. I don’t generally purchase products again if they seem to be poorly packaging since that indicates the initial level of quality I can expect from a company. This isn’t always the case, but more often than not it makes a difference in my opinion.
Both chargers arrived in a nice discrete brown box that contained a sleeve with all of the relevant information about the products inside. Each charger was packaged well with ample protector so neither one would float around in their box during shipping. The chargers themselves were in plastic sleeves to prevent any damage/scratches which seemed to work well.
Pictures:
Overview
Charging hubs are not always an item that many people would consider, but they provide a great alternative, and avoid clutter. These hubs (I have 2 on my desk right now) are particularly important if you have a situation where outlets are limited, or you want a simple way to charge things on your desk. Personally I don’t like having a bunch of things plugged into a powerstrip, so this is why I prefer using a multiport charging hub. The build quality of the Choetech is quite different from my Tronsmart 80W hub. It features a soft touch finish on ~90% of the charger, and the other 10% is a nice textured plastic. The charger itself is very compact for what it’s offering which is nice. I don’t need a charger with a huge footprint since I already have a lot of things floating around my desk (Surface dock, Surface Pro 4, school work, phones etc..) I also wanted to point out the length of the proprietary power cable. The cable is around 6[ft] which makes it ideal in my case because I can move it around just about anywhere on my desk. I couldn’t do this with the Tronsmart that I also have because the power cable was about half of that length.
What’s inside:
-60W 6 Port charging hub
-Power cable ~6[ft]
-Micro USB cable ~3[ft]
Ports:
The 60W charger features 6 ports in total, 2 of which support Qualcomm’s Quick Charge 2.0 standard. The other two ports which are referred to as “Smart Ports” will provide 5V/2.4A charging to supported devices. Since this is a 60W charger it can provide the rated power output for all 6 ports simultaneously which makes it great for when you need to charge a bunch of devices at once. I have 3 phones, an Android Wear watch, and 2 external batteries that I can plug into the hub if I really need to charge them at the same time. There is ample room between each port, so any if not all cables should work just fine. I tested around 15 that I have laying around without any issues.

Overall
I think Choetech made a good multiport hub in a small package that has a lot to offer. I didn’t experience any issues, and I enjoyed the soft touch finish on the charger. I see no reason to not recommend using this hub if it’s something that you need.
Choetech 3 Coil Fast Wireless Charger
Overview
I’ve owned a plethora of wireless chargers over the years, but I sold most of them with their accompanying phone. With wireless charging the design, and ease of placement is what will make or break a charger for me. The Choetech 10W Fast Wireless charger has some nice features that some of my old ones did not. (For reference I’ve owned qi chargers from TYLT, Aukey, Nokia, Anker, RavPower etc.) Choetech made the charger with a low profile, and elongated shape to help with the placement of your phone. On the underside of the charger there are 4 feet that help keep it from sliding around, unfortunately in my case it still moves around freely on both my night stand and desk. (YMMV on how well it stays in place) On the top there is a ‘wireless charging’ logo that is actually a very minimally raised rubber insert that keeps your phone from sliding off. I tried to move my slippery S7 Edge around on it, and it did move, but nowhere near as easily as it would without the added grip. There is an indicator light on the top toward the micro USB input that will glow a different color based on the charging speed and state (see the below color code table). I haven’t experienced any placement issues other than noticing how the S7 Edge acts when you move it off the pad and back on swiftly. It’s virtually impossible to not place the phone on the pad and not have it charge, so that’s great!
What’s inside:
-Qi 10W Fast charger
-Micro USB cable ~3[ft]
Ports:
The wireless charger only features 1 port, and that’s a micro USB input for the pad. It is oriented “Nexus Style” which means it’s upside down relative to how Samsung and other OEM’s have their port. I don’t mind it being this way, and frankly it doesn’t make a difference it was just an observation.
Charging
Note: You need a QC 2.0 charger to power this wireless charging pad in order to use the 10W fast charging.
I will update this area with a detailed graph of the charging speeds once I collect enough data (1-2 days of usage)

The Choetech 10W wireless charger does charge your phone faster than the Samsung Fast wireless charger as can be see in the above graph. All of the chargers were tested the same way from (14% battery) with data recorded in intervals over time.

Standard Non-QC 2.0 port test
Overall
I’ve always enjoyed wireless charging more so than any other type (including USB Type-C) due to its convenience. Choetech made a nice simple high quality wireless charger that I plan to use every day (even when my Samsung one arrives) because I like how it’s designed, and the fast charging capabilities.

Hi, does this actually work with the S7 (edge)? On every ad I've seen for it it says "This wireless charger is not compatible with S7 or S7 Edge."
Now I cant imagine why it would be incompatible but its something that they have put up and it would be great if you could clarify this for us.
I'd like to get one to fit into my ram mount to make a hoky wifi car mount but I'd like to know if it works with the S7E first.

yes it works just fine the S7E but you need a18W wall adapter nkt the stock Samsung one to use it since it requires a higher input current.
