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.

[Q] Best Charger for OPO

So I'm looking to buy some additional chargers for my OPO. But unfortunately you cannot buy the official charger seperatly. Are there any 3rd party chargers that work just as well? I have a few at home that just don't seem to charge the phone fast enough (also, I think it does not hold the charge as long with these chargers, but that could be the placebo effect.) What should I be looking for in a good charger? Is the wall piece more important that the USB cord. Does the type of USB cord even matter if the wall piece has the right "specs". Any suggestions for chargers to buy (preferably on Amazon since I have Prime).
Thanks for the help!

Definitely look got chargers with high A. I noticed that on my old chargers were the A was 1.3, it would not charge the phone or would charge very slowly. The stock charger is great, I use a different USB cable so it's longer in length.
http://forum.xda-developers.com/goo.../hands-best-fastest-cheapest-nexus-5-t2729066 is a good charger, for $5 you can get two of them. They're 1.8A slightly less than the stock oneplus one charger but works very well and the length is very long and is cheap.

What is the stock details of the OEM chargers? Not got mine yet and I usually use some old HTC chargers which are 5V/1amp

Cool, thanks man.
I just used that link and unfortunately ( I found more for a few more $ but I can wait.) they are unavailable at this time but ill keep my eye open.

5v=2a
yeah most of mine are around 1a

The galaxy S4 and up chargers are 2A. If you can find some around somewhere.

The OnePlus charger is a 2A 5V part and the included USB cable charges it relatively fast. However, the small length of the cable pissed me off.
I ended up getting 2 of these - http://www.siig.com/it-products/it-accessories/mobile-phone-accessories/3-1a-ac-dc-usb-charger.html . It has a little 1A USB charge port addon for use in the car's 12V port. The main USB port on the charger is a 2.1A port if I remember correctly. Charges as fast or faster than the OnePlus charger included.
The charger has a little removable two-prong plug (like the Apple chargers) and you can stick any random two-pin power cord on this end, basically giving you as much length as you need. That's what I liked a lot about these. Annoying thing though is the blue LED, a bit bright but nothing electrical tape won't fix.
EDIT: Use any charging-only cable, one of the Samsung 2A cables or the Oneplus One cable itself for fast chargng.

I just got this: http://www.amazon.com/gp/product/B00GTGETFG/ref=oh_details_o00_s00_i01?ie=UTF8&psc=1
and this: http://www.amazon.com/gp/product/B004GF8TIK/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
coupled they are killer. The anker hub is amazing...will provide PLENTY of power to anything plugged into it, and the mediabridge cable is 24 AWG, so it can handle the 2amp that the phone requires...plus it's very long.

the blackberry playbook chargers work great. they have long cords and are < $5 on amazon.
i ordered these: http://www.amazon.ca/gp/product/B00K8HY132/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
they charge fast and work well.

Recommendations for Micro USB cable for Moto G

I'm currently using Sony CP AD2 charger with the Moto G 1st Gen. The cable supplied by Sony is good enough to give an output of 1A (checked with the Ampere app). But since the cable provided was short, I started using a Belkin Mixit cable. It hardly gives 0.5 ampere output. Any recommendations for a good Micro USB cable?

yes, and no.
Any cable will be 'ok'... to make data transfert and 'slow charge'.
But to get the best out of the charger (and it is even more important on high lenght cables) the wire gauge is important:
the thicker it is the less you'll get resistance and energy loss.
a Samsung's USB cable made for fastcharge is great for that (though i bought both the cable (1.2m) AND the dedicated charger 5V/2A which is quite overkill for MotoG)

I back @matmutant. For data transfer, most cables won't make much of a difference. But for charging, yes it can make a significant difference. For the moto g, even if you use a higher guage wire, the stock moto kernel and the CM kernel doesn't support a high current off the USB 3.0 port of the computer from the looks of my experience (even thoughh USB 3.0 supports 2 amps). May be @matmutant can throw some more light on this topic.
So you can just get an AmazonBasics USB cable and be content. It supports a 1A max current. If you wan't something more future proof, the only certified 2A cable I know of available in India is the OnePlus' microUSB cable which is sold separately. If that is not available and you don't want to bother with much research, buy a 2A charger and use the cable included with it.

Regarding my tests, my Samsung wall charger gives up to 1200mA to the MotoG max (although the charger could go up to 2A and MotoG specs say it can handle up to 1.5A):
As usual, the charged device limits power to what it needs, but here i think that a 1A charger is enough as the power regulator (pm8226) used to charge the battery heats a lot at 1200mA ==> it shouldn't damage the device, but prevents from using it much while charging.
On computer, the device won't take more than 500mA, even on the 3.0 port (at least that's what happens on mine ).

I agree with what @matmutant and @pfufle have said. The Sony CP AD-2 charger I'm currently using gives maximum output of 1.21 A (checked with Ampere), and gradually decreases as the battery gets charged up fully. The actual output might be a little higher I guess.
So I'll stick with the AmazonBasics cable as @pfufle suggested. That should be enough for a quick charge.
@matmutant The micro USB port of the Moto G is based on USB 2.0 (if I'm not wrong), which is why the output limits itself at 0.5 A. If both ports are on USB 3.0, then the output increases to about 1 A.

boAt Smart Micro USB cable. It works pretty well. With reversible connector. Can handle upto 2.4 amp. Metallic Braided Cable. Super solid and Quality is amazing. Worth investing 350 INR. I got it on Amazon. Here is the link boAt Indestructible Smart Micro USB Cable (Grey)

Reversible broke easily(
My absolute best for now are Chinese Tronsmart and Aukey cables. Give them a try, and tell what you think.

Fortunately, it still works great. It's been a year or near by that.

Compatible USB-C cable

I bought Blitzwolf 3A USB-C cable which I am using in my car with Android Auto & my HTC 10.
While I am switching to 1+3t I am thinking if I can still use same cable for Android Auto+charging in car
Any ideas?

The cable should be fine, but it will be trickle charge. Only the dash chargers provide quick charging.

I got this one for $6 on Amazon and it's Benson approved. I also brought a few Otium adapters, which sell a pair for $7 and of course Benson approved. They are so small, so I just have them all over the place. One in a bag, one in the bedroom, one in the car, and one in the office. If anyone found a good Benson approved USB-C cables that sell in packs with at least one 6ft, please share.

I bought a pack of these: https://www.amazon.com/AUKEY-Adapter-Type-C-MacBook-Google/dp/B01ANLA6OU/ref=sr_1_5?ie=UTF8&qid=1480436320&sr=8-5&keywords=usb+b+to+c+adapter which work ok and I didn't have to buy all new cables, at least for now. I will eventually get a new cable though.

These allowed you to trickle-charge via standard microUSB, correct? I have a 3T on the way, and I don't look forward to being chained to one charging cable.

Yes, they work fine. Description states it also has a 56kOhm resistor to prevent damage, but I don't really have any way of testing. I generally only use it as a backup at this point.

I had a Oneplus One and the only thing that broke on it was the charging cable, so being tied to one cable gives me pause.

Always go for high-quality well known and reviewed usb-c cable's. As dash charge uses 4 Amps+ you will definitely need a high gauge cable (thicker copper wires) to safely carry that amount of current. Tell tail signs of cheap cables are obviously slow charging but the worse case is a buildup of heat and short out of the cables. Braided also tend to have higher wear and fraying resistance. I went for one of these Anker PowerLine+ USB-C to USB

Yeah I just got one of these but Dash charging doesn't work. Might buy an extra from oneplus and reverse engineer and make my own.

I did discover the 1+3T slurps 1.5A (voltage drops to 4.6V)out of my desktop-PC USB2.0 socket when no data-connection is provided, and nicely reduces the current to 495 mA when connected to USB.
This with original dash-cable and Legion meter. I did not try for long though, as my mainboard is only rated for 1A.
From a good high current (IKEA) 3 x 2.1 A adapter it also takes 1.5A, with no voltage drop. So it looks to me that the phone is charging with 1.5A unless a dashcharger is directly connected, or reduced to 0.5 A when connected to USB.
When connected through my Legion meter, it will charge with 1.5A even if connected to a dash-charger.
From the cable-tables, you can select AWG 23 for 4.7A, AWG 27 for 1.7A and AWG 32 for 0.53A, so there is quite a difference

If you want to be able to quick charge you will be tied down to the stock cable. I have an abundance of USB-C cables that I used to use with my Nexus 5X (charged at 2.3A on average) and none of those cable come close to charging the OP3T at 4A. I usually get around 1.4A when using 3rd party cables.

Gor this one in AliExpress, dash working and fast delivery to Spain https://es.aliexpress.com/item/100-...-Flash-Charging-USB-Wire-For/32708785156.html

I bought this before 3 months https://www.aliexpress.com/item/Ori...32695530105.html?spm=2114.13010608.0.0.nTY2Iz support dash

Also seeing about 1.5a while using high quality cables and powerful charger...tested using Ampere. Just glad that this is my first android phone that I don't need to charge throughout the day.
Previous phones: mytouch4g, s2, note 3, note 4, note 5.... Never really put the 6p through its paces.

Question Is it safe to use USB-USB C fast charging plug with Samsung a54?

Hi there.
I recently purchased a Samsung A54 and noticed that it came with USB-c to USB-c charger. It did not come with the plug. I have been using a normal USB-USB c cable and original Samsung fast charger from an older device to charge the phone (as i do not yet have access to a USB C plug). I have noticed that the charger becomes extremely hot and makes a buzzing sound. The charger also cuts out and restarts again multiple times during the charging process. Is it safe to use the USB charger or do I need to buy a USB-C charger?
Thanks so much

Just replace the charger. It's a lot cheaper than the phone.
I've had good results with the Anker Nano series.

I'd expect this to be the charger anyway and not from the phone with it.
I use the A53 with my old Samsung 15 watt fast charger and the cable that charger came with just fine. There's no problem. The a54 should be no different.
So, I expect the charger to have a problem.

I got the Samsung Charger brick with the phone but I use the Anker Charger anyways! Ive had this for more than a year and I use this as my primary charging brick. Never faced any issue so far.

I was using my old Oneplus Warp charger (65W) and was also getting heating, and phone would only charge for like 10 mins before stopping.
Bought a Belkin 25W USB-C brick and all my issues went away
