Not every micro usb cord is built the same...

Ive been using my OEM charger cord untill the other day it fell off my desk while charging and bent the tip. I started using another cheap 99 cent ebay cord with a blackberry logo on it and it seems like my phones never charged slower. So I installed current widget and it seems to be charging at 280MA while the OEM cord charges at 380MA. Does anyone know where I can get a new cord that charges just as good as the OEM one for cheap?

Amazon has the HTC cord identical to the one that comes with the phone for like $6. My phone charges at around 800ma with the screen off. I suggest spending the extra $5.

FWIW, it might be worth mentioning that your battery will actually last longer if you charge it with lower amperage. The downside to this, is that it will also take longer to charge.
In fact, your battery's overall life expectancy will also be longer using lower amperage charging.
Just thought I'd mention it.

Do you have the link to this still? im having a hard time finding it

i am about to try a few from monoprice.com
too cheap not to try

You can buy the original charger, and cord off ebay from a guy for 10$ shipped..when i bought mine, he had 10 left.

I use monoprice cables. Seems to work fine, although, I never tested charge speed.

did you guys get the USB charge cable with your EVO? I never got one. All I have is AC charge cable, and using my wife's moment USB Charge Cable, and works fine.

Typical Micro USB cables (like those from monoprice.com, awesome btw) don't charge my for-work Blackberry Curve.
Go figure. I hate Blackberries.

Correct me if I'm wrong but that micro usb cable that came with your evo can be plugged into a usb port or the wall charger itself, and it can even be plugged into a car charger hat accepts usb cables.

I'm doing this now, charging my phone from my car charger that accepts USB cables. It charges REALLY slow however, I'll check to see at what amperage.

Charge with USB or the wall charger?

I know that this is a really lame question but I was wondering if one offers a "better" charge? USB charges very slowly compared to the wall charger so I dont want to use it unless I have to.
Also, why does the car charger have a USB hub for the charging cable that comes with the phone if it has a micro USB hub on the end of the cable that is connected to the charger anyways? That is just redundant, is it not?

The wall charger will charge faster... As for 'better'? A charged battery is a charged battery. If you charge it faster than the wall charger allows, there's a potential for overloading the battery (though there should be safeguards to prevent explosive results). But the wall charger is what I'd suggest.
As for the car charger, it's to allow multiple devices. Micro USB for your phone, and a USB port to plug in anything else that might need it (like an iPad or something). If you don't have 2 devices, ignore the USB port and just use the micro USB connection.

Thank you.

Most USB-based charging only goes at 500mA, where as the OEM charger is about 1.5 amps (1500mA). You can find some 2.0A USB car chargers on eBay / Amazon for fairly cheap. They're worth it to get a full charge if you are in a hurry or have a short commute.
Here's one that's 2.1A for $9.99 on Amazon

Silly question, but as long as it's a 5 volt 2 amp MicroUSB charger, it'll work? I just don't want to fry my phone using some incompatible charger.

Warning: iPad Charger
I tried using the iPad charger yesterday and that didn't work out very well. My phone turned off and didn't charge. I couldn't turn it back on, had to do a battery pull to get it going again.
Not sure if this is an isolated incident or not, but I'm going to stick with my Nexus and/or USB charger.

It makes sense that your phone got hot. When using the stock charger (or any charger with a current rating of 1A or less), the charger is the one that is limiting the current to the battery, so the current-limiting circuit in the phone is not necessarily active and therefore not generating much heat. However, when using the iPad charger (which is rated around 2.5A, I think), the current-limiting circuit in the charger is not active because the 1A or so that the phone is drawing is well within the rating of the charger. Therefore in this case, the current-limiting circuit in the phone needs to actively limit the current and thereby generate a lot of heat.
I personally think that it's better to just use a charger that has a similar current rating to the stock charger. I higher-rated one might charge the battery just fine, but I'd rather keep all of that heat in the charger and away from the battery. Although, of course I could be mistaken -- feel free to correct me if I am wrong.

[Q] Car charger recommendations

Hello. I'm trying to pick a car charger that would work with the galaxy nexus. from what I've read so far the samsung CAD300UBEB/STD model seems to do the trick but a few review says that the battery discharges faster than the charger can charge it back under heavy usage. can anybody confirm or deny this?
and also, I would like to know if that same charger would work for a galaxy S2. I'm looking for a charger than can be used with both models because I have both phones. the listing of models in amazon website doesn't list the nexus or the S2. so I want to make sure before buying it. thanks!

I'm also interested. I was just looking at this discussion on Reddit taht goes a little more in depth

The motorola charger listed there seems work well for the nexus and also for the S2 according to amazon reviews.

I went with one of these and a USB cable, and it seems to work just fine. Also gives me a spare USB port for additional charging.

I have the Motorola one already (the one with the blue LED) when I had my Droid 3, now it can't keep up with the Nexus' power drain. Just using it moderately on 3G only in the car today had it drain 3% over 40 minutes.

not according to this guy
I have a galaxy nexus cell phone which requires probably around 1.5 Amps when using GPS. The phone does not come with the car charger. It only comes with a 2A wall charger. My temporary solution has been to use a car power inverter that has house-type outlets on it (which I already had) so that I can use the wall charger in the car. This has been working fine, but for obvious reasons, is not my desired long-term solution.
Enter this piece of crap. Now, the phone and only requires a little over 1 A with GPS. With the real two amp wall charger, I am able to both run GPS and charge the battery pretty darn fast. But, with this charger, not only can I not use GPS without draining the battery, but even when not using anything special, the battery charging times are horrendous.
Stay far, far away.

Wow... granted, I am not using a GPS, but I never really checked the charge times. I don't rely on it for a fast full-charge.. usually just plug it in on the trip home and charge as much as it can until I plug it in at home.
Thanks for the heads up.. I am gonna have to keep an eye on it now.

I've researched this pretty thoroughly, and the key question is whether or not your GN shows "AC" when you check the Battery status, or if it shows "USB."
With most car chargers, it is seen as "USB" as if it's plugged into a computer, and will draw minimal current, generally not enough to keep up. I had 2 different chargers in my cars, none of which showed as "AC". I bought and then returned the Griffin PowerJolt Dual USB Micro Charger - it also showed as only "USB."
Finally, in one of the other Android forums I've been monitoring on this issue, somebody came across this one:
HTC T-Mobile myTouch 3G Car Charger
$3.12, free shipping. Mine came yesterday, plugged it in, and finally my GN showed charging as "AC".
Hope this helps!

When your smartphone shows your charger as ''USB'' this means that the USB data lines in the charger are not short-circuited. Then smartphone reduces its charging current to avoind any problems with USB laptop power sources
I made some experiments to check this point : see http://78michel.unblog.fr/?p=184.
I also opened a car charger and short-circuited the data lines on USB the plug . That way I have solved my previuos charging problem in my car during long trip.

It charges the phone just as fast, if not faster than my home charger. On the way back, my phone was at 35%, within 2 hours it was back up to 100%. No GPS and a couple phone calls.
on the way up, GPS on and it never dropped below 97%.
so i can tell you without any doubt what-so-ever that this charger works perfectly with the galaxy nexus and will charge it with Navigation and phone calls running.

I bought a charger very similar to this one and it works great in my car. I make sure any charger I get is rated 5V DC at 1000mAh at least.

I have 2 USB 2.5A dongle chargers, one by Belkin and the other by Kingston. Both register as charging via "USB mode" and do not provide sufficient power while the phone is in use(loses charge usually). I also have that Motorola Rapid charger but the way the cable is designed it tugs on the USB port and comes loose often. I ended up just using the normal USB cable that comes with the phone and a 140W power inverter. Granted, it's not the most compact of devices, but it works well. I got it from Walmart for $20. Here's a link to it:
http://www.walmart.com/ip/Schumacher-XI14-Power-Inverter/15140199?findingMethod=rr
(and yes, using a power inverter will have the phone registering as "charging AC" and give a full proper charge.)

I'm using a Scoshe (sp?) dual USB port charger I picked up from Staples. It has a 1amp port and a 2.1amp port and I just use the micro usb cable the GNex came with

There was another thread, I think in the General that discussed all of this, what people came up with was the best combination if you want a dual port usb charger is to make sure you have a "charging only" USB cable. This cable will not make your phone think it is connected to a computer. You can tweek a data/charging cable to work but some people messed that up so it is probably worth just spending the $4 on a cable that works.
Here is my combination that works great. With this set up I can have on my navigation going with the screen on the whole time and stream Pandora over Bluetooth into my car and the battery still charges really quickly.
Dual USB Port with a 1 amp port and a 2.1 amp port (2.1 amp port is for tablets or power hungry devices - like the phone while navigating). http://www.amazon.com/gp/product/B0056VNVV8/ref=oh_o01_s00_i01_details
Charging Only USB cable:

Thanks for this. It's been driving me mad how car chargers and cables are so inconsistent. Pun intended.
Seriously, why can they come up with a standard and call it a day?
I have a had a few GPS/Pandora runs. Even while it says AC charging and my charger is rated for 1A, it drains the battery by 300-400ma.

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

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.

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.

Car charger that charges at wall charger speeds?

Any car chargers that anyone could point me to that charges as fast as a wall charger?
As it is right now, unless I have my screen off and no apps running it drains faster than the charger can put juice into it...
I'm just using an el-cheap-o aftermarket car charger.
Thanks!

What I use is a cig to usb plug (cost me 10 bucks at walmart). Then I bring the cord from home that came with my phone and plug that into the USB to cig thingy. Works like a charm, I haven't noticed it charging slower than when at home.

i bought one from t-mobile... its about $29 but its worth the price. I get charge speeds btw 850ma and 950ma when on idle

i have the oem cig to usb charger from Samsung i purchased it at best buy with a gift card lol, when i first got my galaxy tablet.

Just get any standard microusb charger rated at 1a (or 1000mAh ). I'm betting your elcheapo is .5a (500mAh).

I finally got around to ordering that Motorola charger on Amazon - works just how I wanted it to - thanks so much!

our device requires an official samsung charger to charge at full ac speed. there was an article on the xda front page last week about how to mod your charger to be recognized as official.

All I know is that now I can run my GPS with the screen on and still move UP in battery - before it would drain faster than the car charger would charge, so, I'm happy with what I have now.

Actually the problem is that some of the car chargers are not at 1amp output but less .75 or .85. Thats why your not really seeing an increase. The stock charger is at 1amp. I know AllGamer likes to use the Blackberry ones (which i believe are 1.5amps) Correct me if im wrong AllGamer.
So just look for 1 amp car chargers the cable doesnt matter itll hold whatever you attach it to.

So, no matter wht brand charger you have as long as you connect the two middle pins you will get full charge as long as the charger can put out 1000ma?
I really need a good charger for the car, right now i use a blackberry charger at work an it charges pretty fast. But i need to know how do i find the currect charge rate of a charger. Is there an app for that?

Get tmobiles car charger. Its faster than any others I've tried.

As I remember those chargers needed the center pins shorted to be recognized as AC.

This charger doesn't keep up. I have one. It will still drain faster than it charges if you're running a GPS app with the screen on.

Does anyone have an experience with this charger from MONOPRICE

I need a great car charger and really dont want to spend to much money on it. Furthermore, if I am getting a 1+amp charger, as long as i am using the stock samsung charging cable then it shouldnt matter if the charger itself has D- and D+ shorted right?
Im assuming this is something standard on all usb CHARGING cables as appose to data cables.?

You want a good reliable charger at eBay pricing..... spend the money 1 time and be done with it. You could've already gotten the T-Mobile one and been done with it.

For those of you buying the USB 12V Cigarette adapters read this.
Basically if you use a data sync cord with one of those adapters, unless it shorts the 2 data pins together internally (probably not) the phone is going to think it's plugged into a computer and only charge at 500ma (max output for a computer USB port). The write up above explains to short the 2 data cables together (this is done internally with the main AC charger head) back towards the phone so it will charge at 1amp instead of 500ma.
You can buy this cable and just modify it as described. I bought this USB adapter so I could charge 2 things at once.

Let me get this clear.
All i need to look for when it is charging is AC mode. As long as it says that, it doesnt matter what i have or have not done to the cables, AC mode is AC mode.
The charger i am looking at getting is 2.1 amp (because it has a spare usb port...so 1amp per line) and when i plug it in and it says AC MODE then its good to go right.
I just bought a TMOBILE offical charger that shows AC MODE, so when it MONOPRICE charger arrives i can compare. If it doesnt work its another 5 bucks, if it does i can take the tmo one back.
But again i am just wondering are there any caveats to AC MODE, or is it that once AC mode shows that is all that matters.
