Don't know if a universal usb charger will work and if so, we still need the cable. Any thoughts?
you would have to get a USB3 Car Charger which I have no idea if it exists yet
Try a power inverter they aren't terribly expensive on amazon.

HEHEHE This just made me realize that I will get to use the plug in my rear seat for the built in inverter in my Dodge !!! The only reason I can think of wanting a USB3 charger is if I find a mounting solution for the inside of the truck...like the in dash stuff being done with the xoom and ipad.
I'm hoping to combine this:

and this:

with some soldering fun to make my own car charging cable.

What you need is something like this:

Most of the 'universal' chargers out there have USB 2.0 connections.
I plugged my TF into my Nook Color charger (USB 2.0, 1.9A output), but the TF didn't react, so I'm expecting it won't charge the device. Might do it while it's powered off, but definitely not while it's on.
This leads me to the conclusion that the device will require a specific car charger. I don't know exactly how they'll get around the 15V source with a 12V car socket, tho.
While it may suck, an inverter with the regular AC charger may be the best solution. Get a QUALITY inverter, tho.
Already I have gone through 3 car chargers for my note 2 cheap ones and a Samsung charger none work well charging. The best one was the OEM Samsung but there must be a broken wire in there cause it charges then stops i move the cord and it works again. So I am looking for another car charger that actually charges and wont break in a month. Please post your opinions and links to the charger you refer (with best price of course ).
Here's what I use. About the best for any normal use. Had it since launch and so far so good.

Open up the charger and solder the middle 2 pins together. Or short the data cable.

This really is the best option (but I WOULD NOT SHORT THE CABLE). I downloaded an app that measures incoming amps and tried several car chargers. Most of them only output .5 amps. You are better off buying a car charger for the iPad (2.1 amps) or modding a normal charger as suggested and using any data cable.
I use a modded Power-Bolt charger with a retractable USB cable. This combination takes up the least amount of space and rapid charges my phone even if I'm using Google Navigation at the same time.
The Note comes with a normal USB cable and a shorted wall charger. The Note knows to rapid charge when it senses the short.
Rather than butchering either of my Kensington PowerBolts ......yet I chose to use Current Widget to measure output of basic Samsung microUsb car charger. Depending on battery level it registered over .9A at times yet on 2 hour ride last week w/ Google Maps it wasn't enough. I use ProClip device mounts, but for the hell of it bought Samsung's car mount today to see output of its included charger. Top measurement on 80%+ battery was 1.092A ?????? I'll let battery drain down and report back....

I actually just use a cigararette lighter/USB converter and use a USB/micro USB cable and it charges just fine.

If you do decide to butcher your PowerBolt, you won't be dissappointed. I'm getting over 1 amp now regardless of battery life or Navigation. It's a bit tricky with the PowerBolt Duo, but you cannot tell it's been modded.
You have to peel off the top sticker, then unscrew the top. I did not have a torx driver that was small enough, so I just drilled out the torx screws. Then you remove the top, disassemble the charger, and solder the two inner USB leads on the 1 amp side only. Reassemble the charger, add a drop of glue to attach the top, and put the sticker back on. Now I can charge my iPad3 and my Galaxy Note at the same time, while they're running.
I own both the single 2.1A port and the Duo 3.1A. What are you getting out of 2.1 ports? I don't remember getting over .992A with it. Am I wrong to expect closer to 2.1A?
I didn't look under decal yet, but own mini torx set.
Even though I own ProClip mount I bought Samsung Car Dock on sale at CompUsa to see what charging output the included charger produced and Current Widget measured 1.059A while battery was at 73%. It's the first time I remember getting over 1.0A

$10 -- PowerGen Dual USB 2A Heavy Duty Ouput Car Charger for Apple iPad 2, iPhone 4 4s 3Gs 3G, iPod Touch (USB Cable not included) --- Review
Click to expand...
Click to collapse
Has anyone else used the PowerGen car charger with the Note? I have a handful of other ones that all claim to fast-charge devices, but apparently it only works with iPhones and iPads. But since the PowerGen unit is on the list, can I assume people have used it and confirmed it will give me a 1A charge rate on the Note? I need a charger that can keep up with the Note occasionally drawing 1.4 A or more (display 100% brightness, GPS, LTE, Bluetooth all active, running Navigation).
A quick search for "powergen" in this forum only brings up the above thread.
Works like a champ. My battery was charging at 1600mAh while streaming soundcloud and using navigation. Definitely does the job.
I am using my car charger for galaxy tab 10.1 (2.0 amp) and it is working much better than any of the 1 amp chargers I have tried, OEM, boxwave, etc...
I also use the GT 101. 110V charging brick, so when I travel, only one brick and two cables. My experience is that the 2 amp charger works really well and will charge the phone while using GPS full time, where the OEM charger and other 1 amp chargers either maintain charge, or slightly discharge.
Thanks for the confirmation! Of course, now I discover Amazon won't ship that to Canada, and amazon.ca does not carry it. :crying: I'd go see what TELUS has to offer, but I'm sure it will be A) expensive and B) not have dual USB ports, or perhaps not even a detachable cord.
If you do find one, also buy a charge-only usb cord.

Is that still needed if the charger itself correctly supports fast charging? The cord I use now is the one from my Touchpad. I get 1 A to the Note from the AC plug, and the Touchpad gets around 1.8 A. I do also have a charge-only cable (much thinner cord, only two wires), but it doesn't seem to make a difference.

The cord from the touchpad is probably wired correctly internally for fast charge. I bought a similar dual car charger and did not see a difference with the micro usb sync cable. I only saw a difference with a charge-only micro usb cable. The phone sees what pins are connected and determines if it is going to charge in usb charge mode(<=500ma) or AC charge mode(>=500ma).

So you use the Touchpad USB micro cable to charge your Note in the car? I thought the cable is too short? I am looking for a LONG USB micro cable that is shorted so it will give >500mA.
I am planning to buy the PowerGen but I need recommendation on the CORRECT USB cable that is long enough.

I don't think it is, because it also works as a normal USB data cable. If pins 2 and 3 are shorted (D+ and D-), then the cable become "charge only" and cannot be used for data.

Then it sounds like that car charger was an "iPad-compatible" one, i.e.: it does not have D+/D- shorted out to indicate to non-Apple devices that it is capable of more than 500 mA.

The cable is about a meter in length. I only need about half that to reach from the plug to the phone mount on the dash.

So then how does it charge fast then? If the cable isn't shorted? Motorola does the same thing. IIRC its a shorted setup to allow for fast charging. All of my USB cables come from Samsung, HP, and Motorola and I use them as data cables as well

You short the pins inside the AC adapter or car charger, rather than the cable. If I understand correctly, the danger of using a charge-only cable is if you plug it into an actual USB port that isn't designed to supply more than 500 mA. Your device could then try to pull down, say, 2000 mA and potentially damage the power supply on your laptop or desktop.

I'm using the Rocketfish 3.1A Model# RF-M657D with my Note. While using Google Nav, lowest brightness, keys backlight off, Sync off, HSPA+, the phone still loses charge (albeit, slowly). I'm assuming this is because the charger is not internally shorted between pins two and three as it is marketed as a iPad/iPhone charger. I'm using a Belkin Data/Charge cable so I know that is not shorted.
I have been doing some reading and last night, I purchased the "Satechi Smart Adapter Compatible with Samsung Galaxy S (I can't post links yet, google it.) so I will report back when I receive and pair it with the Rocketfish.
One thing I can't understand is how some of you have reported 1600mA from your car chargers. I am reading that without this adapter/cable mod, the Note will only run 460mA or so. With the adapter/cable mod, the Note's hardware maxes out at 960mA. Also, is their an app that allows me to see how much amperage the Note is receiving or are you guys pulling out the multimeter?

Where/how do you get this info? Asking because I'm curious to see how my car charger does. It has usb ports rated at 2A, and I think it's 2A shared instead of per port, but want to see how it actually does when plugged in.

From what I read, your charger is an .5 amp.
It's not like my phone dies or anything, but it'll lose like 5% an hour and I could be exaggerating. Are you using a charge-only cable or modded cable/charger at all? Like I said, I think this phone is only pulling down 460mA without said mod and I find 1600mA to be incorrect as I read the Note will only pull down 960mA max. We'll see what this adapter does for my charge times.

I think it shouldn't produce any harm to the device.
Read THIS for more information about charging through USB.
Absolutely no problem with this.
Just make sure you don't end up using something like this. For those who don't get it, those fake chargers fed 12V directly to the USB connector, supplying almost 2.5 times the nominal USB voltage. Doing this WILL fry most USB devices on the market, S3 included.
Been using 3 others usb cable for charging. No problem so far.

Bought one of the 3FHUBEG HDTV adapters today to mirror my S3 onto my tv. According to the guide i should plug the official charger into the adapter and then plug the charger into the wall. When i do this i get NOTHING on my tv screen and the phone will not charge. I thought the adapter was DOA so after trying many things i removed the wall charger and instead i plugged the usb into my pc and voila it worked and the phone started charging and the S3 mirrored onto my tv.
It seems to be working okay this way but why isnt it working when i plug the usb end of the charging cable into the uk plug adapter and then connect it to my socket? Would i be doing any damage by just powering it via usb on the tv?
Im really confused. I charge my phone normally overnight and it works no problem with the usb charging lead plugged into the wall socket and then the micro usb into the phone but for some strange reason the phone will not power the HDTV adapter this way and will only work by USB power and not mains power. Any help appreciated. :good:
Check your cable first, some of them have 4 pins only and this can be a reason. If not, I'm not sure but wall charger have 1A output and this can be too much for adapter. USB output is 550mA so nearly half of it. Charging from USB won't damage anything, it'll only take longer to charge your phone.

It's definately a 5 pin and its an official cable. I'm just concerned as every video i've seen etc shows the charger being plugged into the wall. When i was charging it via usb, as its a slower charge, the phone seemed to be losing more power using the HDTV adapter than the charge was capable of charging, i.e the phone battery was draining power quicker than the USB could charge it. Absolute mystery.
Hmmm, maybe it's just so badly made...
