So I bought a car usb charger that claimed it was rated at 1 amp. Using both my blackberry and HTC oem usb cables it will only show up as a USB charger (500ma).
This is not exactly enough to charge the phone while using 3g, gps, full screen brightness, etc. I'm looking for a good confirmed 1 amp hardwire (not using a usb cable) car charger and home charger. I used my sisters Samsung charger (rated at 700ma) and it charged it quicker than with the OEM htc charger.
And I would like to try and get ones that are confirmed to show up as fully charging the phone. I would appreciate some insight

And now that I think about it,
I would like to be able to use my Amazon prime for a change, so amazon links would be nice

I went through a few different car chargers, so I can help you out here. I bought the Belkin car charger recommended here in another thread, low profile and rated at 1A, but my phone only recognized it as USB and charging was fairly slow, extended road trips using video recording and navigation while plugged in would drain my battery over time.
I used my friend's palm pre home charger and it worked very well, so I went on to Amazon and bought the "palm vehicle charger". The one I got in the mail (from Park Deals) was DOA, wouldn't turn on at all (I emailed Park Deals and they sent me a new replacement free of charge, didn't even have me ship back the defective one). I called the local radio shacks and found one in stock at $9.99 (radio shack isn't carrying palm anymore, so the accessories are on closeout but hard to find in stock). Works like a charm, the phone recognizes as AC charging, the phone still charges while running navi or recording video.
My friend got a cheapo car kit on ebay, came with rubberized case, mount that fits the evo with the same case on, and a cheap unlabeled car charger with a bungie type cord. I tried this on my phone, my evo recognizes it as AC also, so I assume it would charge well if it's rated at 1A. I've seen several other cheapo car chargers rated at 1A as well.
Another thread here on XDA says that if you modify your charger/cable by altering the middle data pins you can get the phone to believe the usb port is plugged into the wall and draw full current from the charger. I tried covering the two middle pins with a piece of paper and plugging it in, but this didn't work for me. The other methods involved shorting the two data pins together, I didn't really want to waste a cable or mess up a charger and potentially my phone so I just bought a different charger. Another thread mentioned buying a specific rocketfish usb cable had a similar effect.

That was me on both accounts. Love my rocket fish cable. Bought the 12v/usb converter for the car and whether or not i use the pc or car to charge, it shows as ac charger on the phone. I use this cable on all my pc's as well as the usb outlet in my vehicle.
This is the charger that I bought from amazon. It shows up as charging from AC (instead of USB) charging. It's available for Amazon Prime for under $6:
The Motorola P513 micro-usb charger.
Ok so I ended up with the Moto 513 charger as well (950ma rated)

How fast does it charge?
One the 2.1 amp port, the Evo only charges at 1 amp. The Evo doesn't charge any faster with this charger than any other 1 amp charger.

Gotcha, thanks for the info.
I just ordered a Rocketfish cable. We'll see how that works.
Would be nice if they made a Y-cable to get 1amp from 2 USB ports in a PC. I mean, I know they MAKE cables like this but I read somewhere that HTC phones were designed to still only charge at 500mAh even with one of those.
Dunno.
It depends on what you're using as a charging source. When usb charging on my home pc or car, it's AC charging at 1 amp.. But if I'm charging with my Energizer external battery, it's only USB charging at 0.5 amp. This is using the same usb cable.
iGo
Would anyone happen to know what an iGo tip (A97) delivers? I am trying to rig up a custom solution that is hard-wired, but uses iGo tips so I don't have to use the cigarette lighter plug and I have the flexibility at the corner of my windshield to swap tips for different devices.
Right now, I have a 4-port USB hub installed under the dash that is 12v powered. I then use a proprietary iGo cable that uses a standard PC style USB connector on one end and then terminates into an iGo tip connector at the other end. That USB cable runs up to the corner of the windshield so I can swap tips at will.
If I use the iGo A97 tip on their cigarette lighter adapter, it seems to charge, but I am not sure at what rate. If I try to use the A97 tip on the USB hub, it charges for about 2 seconds, and then the light goes out. The Evo does not seem to like the custom arrangement, yet all my other micro usb devices do not seem to have any issues and charge just fine...
Thanks,

I can attest to the Moto 513 working fine - it has served me very well on my Evo and the Treo Pro before it.
Unfortunately it is a big ass charger though - wish there was a good micro option.
How do u determine how much power its actually charging at or if its not using the full 1amp rating?

Should pull 1A off the Igo
how do i determine if its recognizing a charger as ac versus usb? could this be rom specific? it seems to charge much faster with cyanogen than it did with damagecontrol
I have been on the hunt for a charger for my car and home that shows up as an AC charger so that I can get a faster charge. After a bit of tinkering I have found that all you need to do to get ANY charger to show up as a AC charger is to have 5V on the standard USB + & - leads and simply connect the two data wires together. This will tell the phone that this is an AC adaptor.
I actually bought a cheapo 1A USB car charger from DealExtreme and it was supposed to show up as an AC adaptor but it didn't. So I carefully opened it up and de-soldered the resistors that were connected to the data pins on the PCB and verified that there were no more connections going to the two data pins on the USB connector (the two middle pins) and then put a small dab of solder across them. I plugged my MonoPrice USB cable into it and went to my car. Lo and behold it shows up as an AC adaptor AND actually charges at the full 1 AMP capacity!
Just wanted to share this with you guys. If people want to send me their chargers I would be happy to mod them for you (just pay shipping). I was also thinking about picking up a bunch of the USB 1A car chargers from DealExtreme, modding them, and then re-selling them. Would anyone be interested?

i heard you say that before, and i thought you were full of crap. after trying it for several charge cycles, it is plain as day. your battery charge WILL last longer from a slow usb half amp charge. seriously.
sometimes, however, it isn't worth waiting for. in a "non-primary" charging location such as a car, I can see the benefit in catching a quicker "top-off" charge.
I know your post is old, but THANK YOU MAN !!, i was having trouble obtaining only 100mAh from a AA-battery portable charger, modded a cable and now it's working so fine !!
Hmm, I could probably modify one of my short USB extension cables and cut off the data pins and keep that cable somewhere for cases where i'd prefer the turbo charge... Just snap on this usb extension cable (or maybe even an adapter) and boom you're getting the 1A charge
PS: my old WinXP box actually complains and shuts off the usb port if it sucks more than usual 500 mA, you would need to solder two usb connectors in parallel to fix that
I've found a micro USB charging cable on ebay, where the ad says it is for the P1000(7"), and wonder if for any reason it should not work as well with the P7510(10.1") as with the P1000. (search for "P1000 micro USB")
I'm only planning to use it for charging with the micro USB charger that caem with my SGS.
Anyone whit experience or thoughts on this cable adapter?

don't just charge with anything. If you want to get a charger, get a charger. This device doesn't use a MicroUSB anything. You need at least 1amp to push anything to the device and it won't fully charge with that. You need a 5w/2a charger to accomplish a 100% charge. My iPhone USB charger will charge it. Only to 66%. It's 1a. I'm guessing your charger is too. Look on amazon. I got a charger with cable for 20 bucks. Works flawlessly. It's in bulk packaging.

I live in noway, so the U.S plug that came with the Tab is useless for me. my current solution: a 3 ft cord making the total length of my charger almost 8 ft, and i really want something that is easier to carry around. Thanks for clearing that up anyways.

Yes it would work with Galaxy tab.
I purchased the charging/data cable and car usb linked below.
http://goo.gl/Bj0JN for cable.
http://goo.gl/mzvml for dual usb charger.
It would be less than $8 for both including shipping. It works very good and usb adapter gives enough power to charge Galaxy tab very quick. Also, you get a spare usb to charge your 2nd device. Like a phone, gps etc.
Thanks for that!

Nice find, very nice/inexpensive alternative for car charging. Why does the cable need a switch for charge/sync? Samsung one doesn't have that, just curious.

If you use it with a Samsung charger, it'll charge/sync when in "sync" mode.
"Charge" mode lets it charge from chargers that normally would not charge the tab, like iPad chargers.
The way "dumb chargers" signal their presence to a device is with resistors between D-, D+, and the power rails. If the charger has the right resistors, the cable just has to pass D+ and D-. If the charger doesn't, the cable needs to disconnect them and put in its own resistor network.

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

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.

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.

+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.
