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.

P605 Charging Issues - Voltage?

I've had some trouble charging my new tablet.
When I first received the tablet, I plugged it in to the supplied cable and allowed it to charge to 100%.
I used it for a day to run the battery down.
I then left it plugged in to the computer with a standard cable for 11 hrs.
It appears that it didnt charge at all.
Now I drove all the way back to my office to test it again with the factory supplied cable and it does appear to be charging slowly but it is totally discharged.
I've experienced intermittent issues with charging. Seems like it prefers but doesnt require the samsung charger/cable. Are the voltages and everything the same?

Yeah, seems like it wont charge on a usb port. Only seems to rocognize the supplied samsumg charger...

Do you see that the battery icon has a red X over it when you have it plugged into the computers USB port. The tablet needs the power that the supplied Samsung charger puts out to charge that big battery.
On page 9 of the users manual it says "Note: You cannot charge the battery using the USB cable and
your PC"
.

so is it just a 2A usb charger?

When it's got the red cross over the battery symbol (when it's plugged into a computer USB or car charger etc) it does still charge, but very slowly. Probably only with the screen off.

It charges with any standard charger. I use non-samsung charger and it charges fine, in fact I have not removed the original charger from the box.
As with USB it does charge but really slowly, while it shows not charging.

I believe that a standard USB is 1A and the note 2014 is 2A. Can anyone confirm?

Yes, this is correct, my standard Galaxy S4 is 1A, however a computer may put out even less than this.

No. Standard USB 2 port supplies 0.5A. USB 3 port will supply like 1.5A or less. As for USB 2, you may install (if motherboard supports it) ASUS Ai Charger so that it supplies 1A.
I have gigabyte mb and it has its own driver to over supply usb 2 current. With that I have about %6/hour charging rate if screen is off. Using Samsung own charge, I got about %24/hour.
PS: Look like my desk usb 2 port supplies .5A only (%6x4=%24).

I think you're right. I'm using a 2.1A CostCo Charger and it seems to be charging the 2014 P-605 perfectly.

Not to be rude, but what you wrote here makes no sense to me .

i got the charging issue also, with original charger 2A, original USB cable
checking with galaxy current, value at 900mA

my tablet charges perfectly with original charger and cable but using every standard usb charger (2A and 700mA) it charges but the "connection" is unstable: it's like usb is connecting and disconnecting repeatedly.
I've checked every connection, using the same charger and cable with another phone the connection is stable.
Anyone with the same issue?

Xperia Z1 wireless charging?

I have a Xperia Z1 and I was wondering if it is equipped with any functions that enables wireless charging (QI-enabled something)?
Tried googling but found no results other than some news on Xperia Z..
On the other hand, if Xperia Z1 does have it, is it possible to buy any wireless charging pad from ebay and charge it?

Don't know about it,too, but I dug into that tech a while ago in orderto know about pros and cons.
I have to admit, it's a convenient technology to just lay your mobile onto that charger and get it charged.
But there are two big disadvantages from my point of view:
Low efficiency - the induction tech used has a small efficiency, so there's a big loss of energy
Low charging power - the charging rate that is possible with the current tech is rather low, it takes AGES to have your phone fully charged, and I even read about people not getting any extra fuel because they used the phone during charge.
Personally speaking I like the magnetic charger plug for our phone a lot more, because it has hardly any loss and just takes a second to attach it, needing no closing of flaps upon removing.
Just my 2 cent

I have a n4 as well. Charge time is marginally longer/slower. The info you have read is incorrect based upon my and other users that have used wireless charging.

Thanks guys. I do own the magnetic cable (dismantle it for the cable), however it is a nuisance that the magnetic cable only works with the charger adaptor and not with the PC..
Been trying to find alternative ways to get my phone charged other than opening the flaps and I thought wireless charging may be a better idea

Nope. Mine is stock. infact magnetic charger seems to charger at a faster rate for me from Laptop

I have 2 of the magnetic cables: one is original from the sony DK-31 dock and the other from japan. Although the both look identical to one another, they function differently.
The original one doesn't charge from a laptop and has to be used with an adapter
The generic one charges from a laptop and can be used with an adapter, however in a laptop it charges significantly slower. Has to charge all night and it still won't be a complete full charge in the morning - it will be close to full.

1.) The Z1 does not have any sort of wireless charging built in.
2.) The Z1 will charge via PC USB connection, however the output of the USB cable varies based on the standard.
** USB 2.0 can charge at a rate of up to 750mAh with concurrent data transmission. Without data, the charge rate maxes out at 5A at 5V.
** USB 3.0 can charge at a rate of up to 900mAh with concurrent data transmission. Without data, the charge rate maxes out at 5A at 5V.
** USB 3.1 can charge at a rate of up to 900mAh with concurrent data transmission. Without data, the charge rate maxes out at 2A at 5V and up to 5A at 12V or 20V.
3.) Qi wireless chargers are slower than wall chargers as well. A typical Qi wireless charger transmits power at a rate of 750mAh at 5V.
To put this all in perspective, the standard wall charger that comes with the Z1 charges over USB 2.0 at a rate of 1.5Ah at 5V.
A PC USB connection will typically be 50% slower at charging than the stock wall charger for the Z1.

Thanks all for the reply. Yup, my cable is inded the one from the Sony Charging Dock and hence it does not seems to be working with the computers unless it is paired with the adaptors.
At least now I know that Xperia Z1 does not comes with wireless modules.. Keep hoping that it may have.

Is there already any Case out there for the Z1?

You can use it but Quickcharge won't work because the OP3 only supports Dash Charge...
I tried several different chargers: 2A, 2,4A 3A. I'm only getting 1,5A if I dont use the original charger AND the original cable. I tried the original charger with a longer USB-C Cable and it did not dash charge at all.

So if I use a different charger and different cable it'll charge at the same 1.5A's as using original cable and different charger?

Yeah, as reported and reviewed everywhere, the only way to fast charge this phone is with the factory adapters and cables. It will still charge just fine with other adapters/cables - but you will NOT get fast charging with it. Just regular speeds.

[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:

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)?

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?
Thank you!!! :good:

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.
https://goughlui.com/2014/10/01/usb-cable-resistance-why-your-phonetablet-might-be-charging-slow/
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!
