My stock charger says it is 2.0A .
I have a third party car charger with two usb ports: 1.0A and the other is 2.1A
Would it be unsafe to charge with the 2.1A port?

You coul use 2.1 A port. Look on your original plug charger. It is 2 A.
Yep, so doesnt that mean that 2.1A is too much?

0.1 A you could say that is the fluctuation of accumulator current. I say that is safe.

Just looking to confirm what I think I've deduced from the forum.
I can't charge my transformer when it's on or asleep with a standard USB charger, correct? I've invested in 2 different 2.0+ Amp 5V USB supplies and none seem to get the charge going on the Transformer. It sounds like I could turn OFF the unit and trickle charge it (by the way would the 2.0A charger be of any benefit in this circumstance?). It also sounds like the ASUS charger gives off 12V and that's what the Tranformer is expecting to get the charge going, right? If so, I'm definately dissappointed that ASUS went this approach- non-standard. I always like extra chargers for traveling and throughout the house and this has limited me. Anyway, if someone would be so kind as to reply to this and confirm I've read the threads correctly, I'd appreciate it.
The ASUS charger is 15V.
5V isnt nearly enough. If you got it powered OFF, you might be able to get it to full (from empty) in a few days (yes, days).
The TF can be charged normally with 10-15V.
I suggest you read this thread to get some other ideas.
Yea you need a 2 plus amp carger which also is 15 plus volts, and if you want to make your stock charge cable longer you have to use a male+female 3.0 usb cable... a 2.0 usb cant transfer enough power quick enouqh

So much misinformation in this post...
First... The real wall charger is 15v 1.2A. So the 2 amp is just bs...
Second... A usb 2.0 cable transfer power just as "quick" (wut?) as a usb 3.0.
The reason you need a 3.0 cable is because the charger is looking for connection on a pin only present on a usb 3.0 cable. If you dont use a usb 3.0 cable the wall charger will only send 5V.
This is done this way so you can use the wall charger for other devices apart from the TF.
You can open the charger up and bridge 2 connections to make it send 15v all the time. Then you can use a usb 2.0 cable just fine.
Please, try not to spread false information.

Before you correct people how about you do your research first.
Actually if you read the wall plug it is a 15v 2-1.2A. You can DIY a charger as long as it can produce 11v+ at 1.2A-2A and will trigger the charge functions within the tab. USB 3.0 is only required with the stock charger.
Dynex sold "The Ultimate Charger DX-UA" that had a MAX setting of 11v but when tested actually produced 11.7v at 1.7A. I was able to find one but they are rare now bc they haven't been making them for over a year now. It comes with aton of adapters one being a USB. I use it often without issue.
Also they sell on Ebay USB car charger adapters rated at 12v at 2.0A I own one of these also and it works great with the stock cable.

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.

It takes me about 1-2 hours on a wall charger, 2 if it's fully flat. I always try to use the wall charger as it's much faster, but I will use USB attached to a computer if I have no other option.
wall charger is two times faster than the usb! one is at 1000 mA and the other is at 450mA by default. If you want to change that you should install custom kernel.
Usb3 should be detected and the full 900mAh used (which on some compuhers may cause the chipset to power down the port if other devices are plugged in

Maximum is 100. This is the "safety" level that the kernel controls when it detects an "unstable connection" to USB. means either your wall plug, USB cable or USB port on phone is faulty. 99% of the time, it's the samsung cable. Try swapping it for any other USB cable.

Tell me what you think and if any of you can try out the charger.

You already got it ?
Do not bother with quick charge 2.00, although snapdragon 801 support it I don't think our z2 software has that enabled.
Why I am saying that is because the maximum charging current the z2 draws is 1.50 amps (measuring it with one of these)
I've tried different chargers (oneplus charger, anker charger which both capable of 2 amps) and different cables and always the max is 1.50

Yes, I know about that already and I mentioned that in my comment. But as I said the z2 maxes out at 1.5 amps I think because of software limit.

Is that on a dead battery? Current flow will settle down as the battery reaches more charge for safety.
I use a 1A charger from my old HTC phone with the dock at night, but it doesn't feel to me like my Sony wall charger is any faster. In fact, it feels slower. The quickest charges I got were actually through my desktop, my motherboard has a charging feature on the USB 3.0 ports.

Ah sorry, guess I read wrong.
But as Sony and Qualcomm say the Z2 is QuickCharge compatible I think it should be working.
You can't see more than 1.5A because you do not have a QuickCharge 2.0 charger! And even if you would and then plug this USB anpereMeter in between it might block the data transfer making the phone think it is connected to a standard USB port.
I'm not even sure if QuickCharge 2.0 CAN draw more than 1.5A! We only know that it allows up to 9V or 12V.
There are 3A or 4A 9V chargers around. But I don't know how much the phone would want to get.
BTW. With Doomkernel and FastCharge enabled you should be able to demand more than 1.5A... I think up to 2A was available in FauxApp
But I think I failed when I tried. Not sure anymore... ^^ been a while.
