Ordered a universal one with wall attachment and car attachment and when I connect the USB to microUSB cord the phone doesn't charge. Ordered another stand alone car charger and it, also, doesn't charge. If I attach the USB cord that came with the phone to the wall/car charger it charges fine. Both, specifically said for the "Nexus One". Is it an amp issue? Most microUSB charger in the mall cell phone kiosks won't charge it either. Is it a proprietary microUSB cord that I need or a matter of amps or something?
Why not buy from Monoprice.com?!
I ordered 8 USB cords (2/each of 4 different lengths), 2 Car Chargers, and 2 Wall chargers. All work perfectly fine, and I paid under $25. (Wife has a CLIQ, so we got plenty to work for both of us.)
So, I don't know what your issue is... Other than just not going to Monoprice

well I havent ordered from monoprice since customers got slammed with bogus charges... i guess i could give them another try though, but still... kinda weary
Why? I had over $1300 attempted to be spent at Newegg, and my CC company called me and stopped the charges. Got a new CC in the mail the following day. Some random amount at Apple as well. LOL. Fun times.
(Yes, it happened to me. I'm fairly confident it was from the same issue as others..) But, that doesn't stop me from using a company that makes good products, expecially when they just made such a big mistake. Odds are, it won't be happening again for a long while
Either way... Those are risks with online shopping. You just have to make sure that your method of purchase has fail-safes.
I have a CRAP load of mini USB chargers (all HTC stock) and didn't want to buy more. I bought a bunch of Motorola mini to micro adapters off Overstock.com for $2 a piece and couldn't be happier. I also bought the official Google cradle to avoid additional wear and tear on the microUSB port.

I bought a car/home charger from eBay when I had my Motorola Cliq, and my home charger would keep going on/off charging. I later found out that it was the voltage issue, where the charger was giving a maximum of 5 amps and the Motorola Cliq needed 5.1V or something like that.
But most chargers I've bought don't power the Nexus One. What specific voltage or amps should I look for it to have? The two I bought off of eBay specifically said they were for the Nexus One. Neither worked. Sellers are putting any micro SD chargers up for sale assuming they will change the phone. They will not. What technical spec will tell me if it really will charge it?
Could someone post a link to a USB charger that absolutely works? I just bought another one from Best Buy that doesn't charge the Nexus. Made by Rocketfish and is suppose to be universal.
Thats really wierd. Every charger i've tried works fine.
You're charger should be outputting 5V and anywhere from 300mA upwards. There is no max mA limit because the phone will only draw what it needs.
This might sound patronising, and I really dont mean it to, but when you say doesnt charge how do you know?
Do you mean from totally flat it won't turn the phone on and start charging it, or do you mean when the phone is on the battery indicator doesnt show a charging, and the LED doesnt go orange/green?
Or do you mean it never charges to full?
When I plug it in it's as if nothing happens. No light, no thunderbolt symbol on the battery, no screen wake-up, nothing. Nada. Now, the HTC wall charger and usb charger work fine. But if a MicroUSB charger calls itself "universal" it does not mean it will charge the Nexus. The HTC HD2 charger my wife has works fine on the Nexus though.
Hmm strange.
The charge process works like this:
- Charger plugged in causes voltage change on +ve USB line - potential charger detected.
- Phone draws minimal current (50 to 100mA) and tries to negotiate USB power
-- If that suceeds it tries to increase power to 500mA if the USB port supports it. If yes charging starts at 500mA, if not charging starts at 100mA
- If USB negotiation fails, it checks if D+/D- are bridged.
-- If D+/D- are bridged, the phone draws as much current as it can/needs
-- If D+/D- are not bridged, the phone draws a max of 500mA
There's nothing special about the chargers unless they have been wired in some special way for a specific phone. Thats why I'm very surprised these chargers dont work.
I know that if I chop a USB extention cable and cut out D+/D-, my nexus charges at 500mA. I've tried this myself for a totally different purpose. Thats no different to ground and power being wired to a 5v source.
Odd, I have three car USB adaptors and two AC USB adaptors.. All charged the phone, although only the AC charger shipped with the Nexus would do a fast charge, and none of my car chargers would. I found one that was rated 1Ah and soldered the two middle pins, now it works as a fast charger too.
The Motorola P513 car charger (OEM designed for a Droid) gives out 950mA, is super cheap (~$3+shipping), and works great for a fast charge with the Nexus One.

Thank you sir. I've been trying to find a car charger that guarantees a fast charge.
Just ordered one from Play.com for £3.99 w/ free shipping.
Maybe now I can use GPS for more than an hour...
I dunno.
My motorola charger for my old bluetooth (H780?) works fine, as well as the original google charger. I also have a car charger for my old bluetooth as well.
My suggestion, is to only buy name brand chargers?

Sidekick 4g will not charge via wall, but does charge very slow on usb. I tried different wall chargers except the "official" wall charger, even a samsung branded usb detachable wall charger, but it still keeps doing in and out with a beep sound and doesn't charge. Am I missing something??? Please help, this issue is extremely aggravating especially when you use your phone for business. X(
I am on the final smooth maximus rom btw.
Well in my experiance with samsung phones and even some htc modles you have to use an offically branded charger for your modle sometimes, it has to do with the pins and how they line up, now if you use the usb cored and a travle wall charger (I use this set up in my truck for work) you should see a faster charge time cause the voltage is higher and its the right pin set
Sent from my SGH-T839 using XDA App
The connector is an industry standard. There's no problem with the pins not lining up. There's also no difference in voltage between chargers. Being USB, it has to be 5v.
However, some chargers have higher capacity than others. The USB spec allows for 500mA from a PC's USB port, but chargers sometimes increase it to a full amp for faster charging. The phones will still charge from a PC's USB port, but they'll take longer.
Also, some companies (Like Motorola) require a special Motorola-branded charger. It's just because they want to sell more chargers. The only difference between a real Motorola one and a generic one is a resistor between two pins to identify it to the phone.
The Sidekick doesn't have this vendor lock-in crap. It'll charge from just about anything you can plug it into. If it's not charging I'd suspect a broken USB connector on the phone, a faulty battery, or a damaged charging circuit inside the phone.

Thanks for the response guys.. Yeah, this stuff is pretty weird.. it would blow if the port is messed up. The phone is brand new though, would they be manufactured faulty?? In that case samsung tech department sucks!
When you make a million of something, statistics say that a few mistakes will happen. If it's new I'd suggest taking it back. I charge my Sidekick off of my PC's USB port and am often surprised by how quickly it charges.

Hello
I am not sure how to properly explain this but hopefully someone understands what is going on.
My Nexus S (i9020a) doesn't charge properly. The original Micro USB cable that came with my phone frayed and no longer works so I went and picked up a third party one for $20. For some reason my phone will only either charge on an angle or upside down with this charge cable.
(It isn't the cable its self it works perfectly on everything else Micro USB wise)
I do find it weird that I originally thought it was the USB port on the phone that was dying so I cracked it open and there seemed to be no sign of destruction on the board so I put it back together. I then plugged it into my Nexus 7 Asus wall charger with the Asus cable and the phone charges properly no angles or upside down.
Any suggestions besides buying a $24 charger from Google?
Things I have tried:
1: Different wall chargers
(Nexus S wall charger + 3rd party M-USB):crying:
(Original Galaxy Tab 7.0 Wall charger + 3rd party M-USB):crying:
(Asus Nexus 7 wall charger + Asus M-USB):good:
2:Cracking the phone open to check the usb port on the board.
Phone: Nexus S i9020a
Carrier: Telus
Rooted: No
Version: 4.1.1
PS: Let me know if you need anymore information.
The thumbnail below is what I mean by Charge on an angle.
I doubt opening your phone will show you if the usb port is broken, unless you opened it previously. The most likely problem is that your USB port is worn out, dirty, etc and it's having trouble making contact with the cable ('charging at an angle' is usually caused by this). My recommendation is to try to clean it. First power off your phone, then try sticking something that can scrape the little metal pads in the usb port. Be careful that you don't bend or snap anything inside or outside the phone, so be very gentle.
Another possible reason, which is a problem I've run into myself, is that the charger you're using just doesn't work with the phone. My Nexus S doesn't charge when I connect it to a generic USB charger in my car, nor does it charge with most wall chargers and the original Wall charger that came with my phone was DOA. The only way for me to charge my phone is at my computer or with some wall chargers that, I guess, output more amps (I'm noob when it comes to electrical stuff! ). If it doesn't charge in one USB port, try connecting to another one and/or switching cables.
If it doesn't charge at your computer, then it's probably dirty.

Thanks for input.
I don't think the plug is worn out since it works perfectly with my Nexus 7 charger. I did look into the bottom of the phone and it does look a little dirty so that could be a small part of the issue but that doesn't explain why it it would work perfectly with one charger and not another. It does sound like it could be just the wall chargers I am using are not as good as the Nexus 7 charger (When I use the nexus 7 cable and charger the cable seems to fit alot better and it very firm when it is plugged in where when I plug in my 3rd party cable it is loose and feels like it is going to fall out. I might just buy the extra asus charge set from google since I know its a 100% work rate. was just hoping I wouldn't have had to spend that on just a wall chargers. >...<
So I use my phone in the car quite a bit. I usually connect audio through bluetooth and run a navigation app. When i do this, even with the charger plugged in, I slowly LOSE battery life, I can't even hold it at its current level. If I'm not running anything, my phone will slowly gain charge, but I'm wondering if there is any kind of stat I can look up to see if my charger is defective.
Thanks

It sounds like your car charger is not putting out enough power. Make sure your car charger matches the output level of the stock wall charger that came with your phone.
If that's not the case I'm at a loss.
Well its definitely not the same output as the wall charger. Even on my old phone (Incredible) it charged much slower int he car, but at least on that one it would still charge. Could the power draw on the S3 be that much greater?
I don't have this issue with my SGSIII.
I use the Device for Phone & music via Bluetooth to my Car Stereo, and Navigation. Charging has never been an issue for me. I didn't buy the Car Charger Accessory for the SGSII but instead opted to use the Car Charger that came with the mounting kit for my old Google Nexus One.
If you have a Car Stereo that has a USB Connection port, I would'nt recomendyou use that to charge your phone as most models don't put out enough Juice to charge a powerhouse like our phone. As with mine I used it one time to try and charge my phone and it only trickled charged it.
The output on the stock charger is 5V 1A
Ideally it would be best to use a car charger that output 1A
For comparison my old blackberry car charger puts out 0.5A and my old iPhone "quick" car charger aka iPad charger puts out 2.1A
The lower the amps = slower charge sometimes slower than your consuming.
That being said if Samsung put in all the proper safety features you could use a higher amperage and be ok as it would limit the amps pulled... If they didn't it could create too much heat and shorten the life and stability of your battery.
I would recommend locating a car charger that is equal to 1A and play it safe.
Hope this all helps... I'm not an expert at any of this but I researched this exact issue myself before as I wanted to know if it would be safe to use my iPad charger on this GS3 as I did my iPhone for quick dirty chargers... Short of it... I don't..
I'm currently using this
http://www.amazon.com/gp/product/B003HM27DG/ref=oh_details_o00_s00_i00
I like it mainly for the cord retractability. I will try and grab an old micro usb charger from my parents and see if it makes a difference in the charging.
From looking at their website it says that charger is 600mAh
I don't know enough about power, etc.. To know what that converts too in A. But if I had to guess I would say it's lower than 1A but maybe somebody else who knows more could chime in as I would hate to give you any false information...
Either way, I hope you get everything straightened out
We have used these Verizon dual USB chargers (i.e., they have a male micro USB connector and also a female standard USB connector - so, you can attach a second cable for dual charging and/or use a proprietary connector, when desired) for some time now in two cars, both used almost daily. They charge well and only one had a connector that got a little loose after nine months, then was replaced with the same model. You can find them rather cheap at other sites and eBay, as compared to full price from Verizon's store.

I have this hardwired into my WRX:

I ran it off the clock circuit (my clock is dead anyways) but any switched 12v source will do. It charges my car integrated Nexus7 without any issues, and at the faster rate.
I have another powering a servo and an aux USB port, but unfortunately I ran so much wire to get it into the center console by the handbrake it charges at USB rates.

There was a thread somewhere that explained why some chargers won't do the 1900mah charge. He figured out where and what size resistors to put across the wires to enable it. I think it was in a car dock thread, I'll try and find it.

It's the shorting/grounding of the data pins that activates 'fast charge' mode on some phones. Nexus 7's and my E4GT (Sprint S2) when I used it didn't require the pins to be shorted to charge faster. Mostly it was the charger (duh) and the quality/length of the cable that affected the charge speed. As well, most of the heavy 1A plus chargers short the data pins in the charger itself so you can use any cable. I believe the S4 doesn't require it as well, but don't have any data to confirm it.
The way I wired mine was to sacrifice a USB female port from a USB extender, and attached the power leads and shorted the data leads. Figured it couldn't hurt. The converter doesn't care if it's putting out 500mA or 3A. It's not intelligent like some chargers in what current it doles out.

Yours is the second post I've seen where someone has shorted the data pins on a charging-only setup. Is there a reason for doing that?

MichaelBR said:
There are some reasons why it won't work, and some ways to solve it. First, let's understand how it works:
The USB cable has four pins. The inner two pins are where the data goes through. THe outer, power.
When the USB cable is plugged in to a computer, the data pins are connected normally and the phone knows it can only draw certain amount of power
When the cable is plugged in to a charger, the two middle pins are shorted, and the phone knows that it's NOT going to be sendind/receiving data, so it can draw as much power as it can. That's why it charges faster with the charger than when plugged in to a computer
Most chargers short the two pins. Some cables have a switch to do that.
There are different cable cauges as well, with different power capacities.
Some USB chargers, notably car chargers and some low-end (i.e. not good brand) chargers that don't draw from the car/don't give the phone as much current as it needs.
So, if any of below, the phone won't charge, or won't charge fast enough. Or, worse: it may appear as charging, but actually losing battery charge!
Cable too long or incorrect gauge
Middle pins not shorted for some reason
Charger doesn't deliver enough current
And the solutions are:
Don't use cable extensions, cables that are too long. Stick with the cable that came with the phone or with the charger
Get a good car charger, that delivers the right amount of current
I imagine you just got the cable from your original wall charger and plugged it in to the car charger. If you did that, then chances are the cable is OK, and the charger is the culprit. If this is the case, then get a better charger. Check how much current that charger can deliver. Check how much current your device actually needs.
Hope this helps.

To be clear, there is no indication it is *required* for the S4. Mine quick charges just fine without shorted data leads. However I did this because my friends have a variety of phones and it only took a few minutes to do.

While I agree with what you posted in general terms, below is the link to the thread I was talking about. He did some testing and found the pins aren't just shorted, but shorted w/ 82K resistors to get the maximum charging current.

Will it damage the phone to have a 3A charger plugged into it? Also If it does not damage would it be able to run the camera as a "blackbox" and not die? I currently have a 2a charger and when i use the black box software it dies after about an hour or so.
SUCCESS!
I got the little black box in from eBay.
Gave it a quick/test wire setup. This is NOT indicative of the end result which will be soldered & have shrink tubing, etc.
Okay, first I grabbed my stock S3 data/charge cable.
Snipped off the standard USB end.
Cut off the ends of the pin 2 & 3 wires since they were not being used anymore (data pins).
Then attached the red (power) from the S3 cable to the yellow (power) lead from the little black box. And did the same for the black (negative) leads.
Then hard wired the red & black from the little black box to my motorcycle battery terminals.
On the first test, I only got 460mAh.
Then I decided to short the 2 & 3 pin wires (green & white) on the S3 cable together (attach them to each other). This gave me 1120mAh!
Next I took the tin-foil and wire braid from the S3 cable and tied them together with the negative lead on the S3 cable. This gave me 1220mAh!
Still not satisfied, I then cut down the 5' S3 cable and made it a 1.5' cable.
AND THIS RESULTED IN A FULL 1920mAh!!!! Right on.
That is exactly the same mAh as the stock S4 wall charger & cable combo give me. Very stoked about this. So now I'll do a nice clean install on the bike and then duplicate it for my car dock sometime soon. FULL CHARGE AHEAD!

No, it will be fine. The phone only draws 1900mAh. If the phone were drawing 3000mAh then there might be a problem.
All done and installed now. And working great!
Negative battery connection (I forgot to shrink tube it but will do that later).
Braided negative wire (~16 to 18awg?) running under gas tank to front of bike.
I wish I would have waited till I got black zip ties in. I hate white zip ties.
The braided wire at the right side of pic that goes up above the gas tank is the pos/neg wire lead that plus right into the phone.
2A inline fuse connecting via blade connector (sorry MC) to a previously used power-on-ignition wire.
This goes to (+) on the little black box.
Note the shrink tube over the braid over the crimp connector (wire goes to top-right of screen).
Phone sitting next to the phone dock I made out of a holster that came with my phone case.
You can see the braided/shrink tubed MicroUSB connector already plugged into the phone.
It's not showing a charge though, because the ignition key is not turned on.
Phone is inserted into stable dock (it will never fall out unless I crash hard).
Ignition is turned on and battery is charging!
And proof that it's charging at the full 1900mAh. Success!

2) Rocketfish Bluetooth Music Receiver (with aptX), with DC 5V power out (connected to 3' 5V to USB power cable)
Plan to use this to convert (found on EBAY - I can't post links here in XDA yet/new user): Dual USB Cable Connectors Power Adapters 8-22V 12 V to 5V/3A DC Volt Converters... to connect directly to my car battery to power both the Samsung charger and the Rocketfish.
I'm new at this and I'm wondering if you all think this will work, or if I'm missing any steps, or if there are other better suggestions?
Thanks for your help!

Just realize that if you wire it to your batter there will be a small draw from the converter and chargers even when not in use. If you let your car sit for a week or long weekend you might come out to find the battery dead. I personally wouldn't wire anything directly to the battery, especially since you didn't mention an inline fuse. Find a switched 12v lead inside the car. Not only does this protect your phone, charger, and car, but it also means you don't have to run anything through the firewall, which is a pain.
You can either tie into the cig lighter wiring, or find something else (I used my clock circuit since it runs to a 10A fuse and is switched).

Your clock circuit is switched?
I agree with the firewall being a pita, but I'm not a huge fan of tapping on to other circuits either. With nothing charging, what would be drawing any current? If there's anything, it would have to be minimal. It also allows you to charge a phone/device with the car not running, sometimes very handy (and a modification I've made before for just that reason). An inline fuse is also a must, good point!

Yes, my clock circuit has a switched lead to wake up the clock as well as a hard wired lead to retain the time. Both run to the same 10A fuse.
There is a small transformer in the converter and the receiver bluetooth will stay on. They have a small energy draw which is not negligible over a long period of time. At the very least I would include a dash mounted switch to completely shut the charger and receiver off. For instance I have a bluetooth OBD adapter (Not too much unlike your bluetooth receiver) that drained a 2 year old car battery over a week I left the car sitting while I was on vacation. For day to day driving it's not a problem but my OBD adapter isn't hardwired and I can just remove it when I know the car will be sitting.
Thanks

Oooh, good point! Makes sense to me. I have never done a mod to my car's audio system so I'll be paying a professional installer. I'm so glad to have this information before I shop around at the good places here and get some offers!
Thank you!
