Automobile Quick Charging Solution

What is the best solution for quick charging the Galaxy Nexus in an automobile?

I have started to use 12-220 volt converter so I can use wall chargers.

I have bought a few of the low profile car usb chargers but they were never recognized as an AC charge. Come to find out, it was the USB cable. I bought a usb charging cable from Amazon last week and it goes in the USB charger and the phone does not think it is a USB charge. I have not timed it but it is recognized the same as the wall charger.

+1 .. this solution has been working great for me, as well.

I've been getting 2.1A car chargers (look for ones for the iPad), most of the ones I had prior to this were 700mA or so and they can't keep up with my 1A phones. Be careful of dual port chargers advertising 2A, they may only be 1A each and may be "optimistic" about that rating. And don't worry about getting one rated for too much current, the Galaxy Nexus won't pull more than an amp no matter what the charger rating.

Some really good solutions here and thank you all for the help.
I'd really hate to use an inventer in my car just to maintain a clean install, so that really isnt an option for me.
Was really hoping to be able to use a off the shelf car charger with the correct pins to trick the GNexus into thinking that it was charging from a USB port, but the above solution should work well with using a socket USB charger.

I've never run into a car adapter that looks like a USB port, including the VZW charger with a spare port or the cheap 2.1A chargers I got from Amazon. My guess is that a charger not built correctly and leaving the data pins open only supports ~500mA anyway. Even if that's not the case I have a moral objection toward buying a cable to fix a design flaw in another cheap product - but that's just me

I've got a charger similar to http://www.ebay.com.au/itm/USB-Car-...ccessories&hash=item4ab18358f4#ht_1638wt_1392
All I had to do was undo the screws at the top, put a bit of solder between the middle usb pins, and my phone recognises it as a AC source rather than USB.

There has got to be a standard car charger on the market with the middle usb pins already soldiered!
I found this on Amazon which advertises itself as a rapid charging device.

Make sure the charger has the IC (rapid) chip. I use this one:
http://www.amazon.com/Motorola-Vehicle-Adapter-micro-USB-Charger/dp/B000S5Q9CA

I've heard that Motorola one mentioned a lot as a good one.
The nice thing about having the low-profile usb plug is (a) it is low profile, (b) I can use it to charge other devices. The charge-only cable is only about $4, so I had no issues buying it to work with this to charge as an AC charge over a USB charge.

I have this one and it charges just like it does from the home outlet and its says "AC" charging. I bought another 8 for family and friends and they all love it.

I think I've figured out the disconnect, I've run into chargers that appear as a USB host which limits the charging to 500mA on previous phones I've had.
You guys are concerned about USB vs. AC charging mode. Of the chargers I've got, this one lists as AC while the rest as USB. However, the fact that the other chargers all work just fine keeping up with GPS+streaming music indicates that the USB vs. AC really has no bearing on the charge current delivered. I'd stay away from charge-only cables just because they'll get mixed in with your standard USB cables and you'll knock yourself out wondering why they don't work. On the other hand, if you really want AC in your battery info order the one I linked.

I keep it in my car... i think I've heard on other threads that USB charging doesn't keep up with GPS (for Directions). Any verify?

What's much more important is the rating on the power source. The GN can pull up to 1000mA, if your charger is only rated for 800mA (like many car chargers) it doesn't matter if it's in AC mode.

makes sense.. the one I use has dual usb (1.0 and 2.1)

You went and gave me a project for the weekend, and once again science prevails over anecdotal evidence. I took each of my 5 chargers and hooked them up to a 12V power supply that measures current. I then recorded whether the charger reported AC or USB, for the ones with USB I modified a right-angle adapter to short out the data pins, and I measured the current. The contenders:
Verizon Wireless Dual Charger
XTG Dual Port Charger
Griffen Powerjolt Dual USB Charger
Griffen Portjolt Micro
CostMad Dual USB Charger
The VZW model was USB out the external port as I had tested before, however AC out the built-in cable which I hadn't bothered to test. It pulled 0.25A @12V via the USB port and 0.59A via the cable. Hmmm... A hole develops in my previous observation. While I had used this on a long car trip with no issues, it was via the built-in cable.
The XTG was new, I hadn't used it before as it's in the car I rarely drive. It reported USB and 0.22A. With the adapter to make it report AC it pulled 0.48A.
The pattern was set. I had expected the Griffen adapters to be built more appropriately but the dual charger reported 0.22A without the adapter and 0.42A with. I had used this without losing charge in the past so this was surprising to me, but it's possible I just wasn't drawing as much current because the screen was dimmer or something.
The compact Griffen adapter (which is great for a laptop bag, BTW) pulled 0.21A and 0.47A respectively.
The cheap CostMad adapter was the only one that performed well out of the box, both reporting AC and pulled 0.57A.
In theory, a perfect adapter should pull 0.42A. Anything more is waste, anything less means it's not keeping up. I have doubts about the Griffen 2x allowing for a full amp, but the VZW and CostMad chargers are pretty lossy. What's even worse is that I'm pretty sure the VZW charger is rated for 800mA (but I can't find an actual spec on it) which would mean that it pulled the most power for the least current. Not that this really matters unless you've got an electric car.
Sorry for misleading you earlier, I should have checked the other port of the known-good VZW charger and probably doublechecked the numbers on my other "known good" charger. Still hating cables that work for charging but not for data, I ended up modifying each of the chargers to short the middle pins (except for the VZW one). If I didn't have the soldering iron for this, I probably would have gone for some of these instead.

I'm using the same one and it works perfect. Charges even when GPS navigation is running.
Make sure you select Amazon as the seller though. I heard there are a lot of fake ones.

+1 to those recommending this one. I have this exact model and it does indeed charge at the "AC" rate, about twice as fast as the "USB" rate.

The Motorola one will charge even when using GPS. I have a friend I bought one for that uses his GPS all day and loves the Motorola charger.

Charge 2 SGSIII's at once?

I would like to get a charging cable that has 2 Male Micro USB connectors and 1 standard Male USB connector.
These are supposed to charge 2 cell phones through one USB charger, but I've read that you might need a higher capacity charger than comes with your single cable charger.
Will the standard USB charger that comes with our phone work, or will I need a higher capacity charger?
Thanks

Our S3's can charge at approximately max 1.1amps and perhaps more on a custom rom. Our stock chargers will not likely provide enough to charge 2 S3's at that fast rate. But, instead it will likely charge both at half that rate. So. I would get a charger that can handle more than 2amps...preferably 3amps so that there is plenty of headroom especially if the charger specs are over-rated. The S3 will only use what it needs and of course, it will slow down the charge as it gets closer to being fully charged. Also, note that if the USB Y-cable or splitter is not wired correctly, then it may not charge at fast rate.

I have a usb 2amp cigarette lighter charger and it has 2 usb ports for charging and charges my S3 and an HD2 together at fast rate when I use proper usb cable(s).
On a 2sec Google search, I found this 3amp usb wall charger (2amp + 1amp) example...or this Scosche 4 port 4amp wall charger although it says each port is limited to 1amp max. You can always put in a USB Y cable making 2 ports merge into 1 yielding 2amp max output...if necessary.
Here is a 2 port x 2.1amp per port example..which would give you maximum headroom and might work well for more demanding tablet devices etc.

[Q] EU Charging methods

I live in Finland and just ordered the Nexus 7 (2013) from the US. I just realized we have different electric plugs and won't be able to use the default charger without an adapter. Couple of questions:
1) I have two miniusb smartphone chargers. The HTC charger says "Output: 5V = 1A" and the Nokia one "Output: DC 5.0W 1200mA". Will I be able to use these to charge the Nexus 7?
2) I think it's possible to simply use a piece to change the US plug type into the Finnish one since the adapter supports universal voltage and amperage ranges. Will this be the safest and most efficient way to charge?
3) It's possible to use a computer as USB power source. Will this work and how does this method compare efficiency/safety wise to 1) and 2)?
Update: support.google.com/nexus/7/answer/3257354?hl=en
The input voltage range between the wall outlet and this charging unit is AC 100V–240V, and the charging unit’s output voltage is DC 5.2V, 1.35A.

Your Nexus 7 can be charged via the USB port on a computer only when Nexus 7 is in sleep mode (screen off) or turned off. Charging through the USB port will take longer than charging with the USB charging unit.

4) Wireless charging looks sexy, but how does it compare to 1, 2 and 3? Any recommendations in that regard?
Update: Wireless charging has a speed penalty and the chargers seem to be quite expensive.

Your Nexus 7 will be fine with any USB charger. I have tested mine on 3 different chragers with US, UK, and EU voltage. My USB chargers all say 100-240v. I know EU and UK is 240v. So yes you will be fine with any usb charger.

As far as I know, all micro-USB chargers can take an input voltage of around 120-240 V, which it what you'll find pretty much everywhere in the world, and supply 5 V to the device, so no need to worry about that. The only difference between cables is how much current they can carry, but your battery will only suck as much as it needs to (unless it's limited by the cable, of course), so there is no way more current could go into it then it is safe.
I have also bought my N7 in the US and use it in Europe and charging it by using an adapter to convert from the US plug to the EU one works just fine.
Connecting it to the USB port on your computer will only give about half the current, which is why they say you should keep it off while charging. It will take about twice as long as using a wall charger and there is no gain in battery health. However, if you want to actively use the device, the current supplied by your PC may be less than how much the tablet is using, which will result in an overall (slower than usual) discharge.
I can't say anything about wireless charging, as I've never used it and I'm not planning on starting now.
tl;dr: Use any USB charger on any of your devices, no harm will be caused. The only difference that could show up is charging speed. :good:

G5 charging slow on 99% of cables

Hey!
I noticed recently that my G5 charges quite slow. So I tested all of my powerbanks, cables, and wall chargers, in various combinations. I had 4 different powerbanks, 3 wall chargers, and 4 cables.
I used a USB ammeter to measure the power draw going through the USB cable.
On the motorola charger and cable that came with the phone, it charges at 1.8a. I then charged my phone from each powerbank and wall charger, using each cable in turn. The average charge speed for my phone was about 0.5a. Out of 28 combinations, only 2 yielded a draw over 1a.
I have created a spreadsheet detailing the charge speeds of each combination, but unfortunately cannot post it yet (10 post permissions).
I then charged my USB powerbanks from the same wall chargers, using the same cables. One powerbank charged at over 1a with every combination, and reached over 2a on numerous combinations. This proves that the cables and wall chargers are not at fault, it is a phone issue.
Why? Has motorola put something in their chargers that 'talks' to the phone, and allows for faster charge speeds? 0.5a is awful!
Secondly, does anyone know of cables that I can buy, which will support fast charging for the motorola? I have looked at genuine motorola cables, but there is no way to tell one from the other.
Thanks!
Paul
P.s. charge speeds were the same, whether the phone was switched on or off.

Welcome @agour
I've come up to a similar conclusion with a lot less data (thus I didn't share them).
I caught power consumption at the wall outlet when charging my device with two chargers: Motorola stock charger and a Samsung Adaptive Fast Charger.
The Samsung has the following specs: 5V 2A or 9V 1.67A with fastcharging capable device.
Using Samsung Adaptive fast charger and Samsung 1.5m cable : 6W, so the device charges at something like 5V 1.2A...
Using Samsung Adaptive fast charger and the cable provided with my XT1676 : 11.3W (which is coherent with the max 9V 1.6A, and would mean the charger provides 2.2A if at 5V which more than the specs.)
Using stock charger and stock supplied cable : 11.3W ==> fast charge for similar reasons as above
Using stock charger and Samsung 1.5m cable : around 6W ==> low power charge
I'd need a USB multimeter to confirm those data. (mostly due to the variable voltage that can provide fast charge adatpers)

Interesting! It's suprising how much difference the combinations can make.
I don't think I have experienced this on a phone before, however I have never felt the need to test it...
I tested the original cable that came with the phone, and an off the shelf 'genuine motorola cable'. The stock cable is still the fastest, however the secondary cable still worked very well.
Interestingly, one of my powerbanks will charge at 2.2a from pretty much EVERY powersource and cable combination. This is with 7 cables tested, and 3 USB wall adapters.
Shame that motorola doesn't allow their phones to draw maximum power from hardware that can provide it..

If I have some time, I may test internal impedance of the cables, it is possible that the device somehow probes the cable (or the cable + charger) and then decides if it can or not draw that much power without overheating/melting the cable; and then it will negotiate the quickCharge with the charger.
there has been a discussion about quick charge on this thread a while ago (before I got this devices : https://forum.xda-developers.com/g5/help/quick-charge-3-0-support-t3632457)
Lenovo adds the following that I have not tested:

It is quite obvious that especially cheap cables will charge phones much slower as the resistance is too high, even if the phone does not perform any checks. Those cables are basically too thin. Resistance limits the current (amps) that can flow. Newer phones most likely just look at the charge current during the first x seconds (or less) and then decide wether to enable fast charging or not to keep the cable from heating up. A wire with high resistance is basically a heater. So it's a necessary safety feature (from the companies POV).
Regarding the power bank, it may be possible that this particular design provides a voltage slightly higher than the nominal 5 volts (still fine for most devices), which helps overcome the resistance. That is also the reason why the Samsung fast charger provides 9V: You don't need a cable as thick as with 5V.
Keep in mind that the USB specifications only recently got updated for such high charging currents, so it is advisable to use only the cable that comes with the phone as USB cables in general don't need to provide such high currents by spec!

That sounds correct, although my Samsung wall adapter is fast charge capable, and was provided with a cable (and not a cheap one), that basically can't be use for fast charging with the G5, that looks silly...

[Q] Need a new charger - where should I look for a good one?

Hi.
Two questions:
1. Where should I look for one?
Found this on Ali-express but wanted your opinion:
http://bit.ly/2ze7U2U
2. Regarding the cable: are all cables the same? Or is this (in link - the one that comes with the OPO) different (can move more current)?
Trying to save where I can
Thank you!

I have been using a 5V 2.1A charger (from Belkin) but with a "regular" old Samsung micro-usb cable and it took 6 hours to charge till full.
I can't imagine it's right.
Perhaps a new, more powerful cable?
Also, how long should it take to fully charge the One?

if you use cable that support fast charge you can charge your phone less then 2 hour...just get a cable that support fast charge or support quick charge 2.0 and you will see the difference....

getting a good cable makes all the difference. I'm not sure if it is due to Lineage, firmware or the kernel... but my OPO has been very picky with the charging cable for at least the last 9 months. I first noticed this when my Jaybird Bluebuds X flat short cable charged significantly faster (then i lost the cable). then on some cables, it would say it's charging but the percentage would remain constant or even drop at a slower rate! I then tried different cables and charger combinations using the the AccuBattery app and OPO Charging Current app to note the ampere.
the xiaomi fast charging micro usb 1.2m flat cable is cheap and charges "fast". I highly recommend the xiaomi cable (i even bought like 4 of them for the office and for home).
paired with new-ish samsung quick charge chargers (which came with the S7 and C5 Pro that i had lying around), i get about 1.58A (screen off).... i also get comparable results with an old Samsung Galaxy Tab 10.1 charger from like 2011 and an ipad 3 charger.

well I went with blitzwolf ...I don't use my original charger as blitzwolf is faster(just a tad but still) ...BW-S5 is my main and I've ordered an BW-S9(I'll make BW-S5 a second to charge my phone in my shop and also charge clients phones/tablets if needed - I fix them too)
BW-S5 has an extended review from a dude with all the pros and cons ...great review if you want to look at it(he'll do the S9 as well but didn't receive it yet and I couldn't wait, I needed a good 2nd one)
P.S. Using custom cable made by me to avoid getting slow charges(only power cable, no data - for safety too)

I'm on this charger: http://s.aliexpress.com/qeaIfIrE and reversible micro USB cable from the same manufacturer (reversible micro usb seems to be not available to buy any longer though, I can see regular micro usb only)
Both are excellent.

Chotech SMT0008 5V/2.4A charger
Hi anybody who want to use a longer cable (1.8m -3m) without losing the charging speed, I would recommend Chotech SMT0008 5V/2.4A charger. You would be able to increase the charging speed up to 10-15%.
https://www.aliexpress.com/item/CHO...er-for-iPhone-Samsung-Xiaomi/32742790687.html
This charger can supply up to 5.5V to compensate USB cable resistance (especially when using a longer cable).
https://lygte-info.dk/review/USBpower Choetech usb 5V 2.4A SMT0008 UK.html
Don't forget a good quality cable as well for fast charging. Up to 1.5m 22AWG is OK, but over 1.5m get a 20-21 AWG cable. If you want to learn about cable resistance during charging the below article is helpful.

I myself use Chotech SMT0008 5V/2.4A with a Tronsmart 20AWG 1.8m cable. I have tested some cables: Mageek 21AWG 3m, Blitzwolf 21AWG 1.8m, Ugreen 22AWG 1.5m all of them are OK. Avoid VoxLink cables !! their "fast cable" uses fake 24-28AWG!
