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.

You will be charged at much slower rate (limited to 500ma max), or not at all if your phone battery is almost dead. iPhone chargers are designed for iPhone only. You will need a Samsung auto charger (some other non-iPhone smartphone chargers may work too, just not iPhone chargers).

It will definitely work. The question with those cheap ones is, how long will it last. I usually try to find an OEM branded one like this:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250973439590#ht_2859wt_1000
Typically, chargers with USB port on it will only do slow charge. In order to support fast charge, you will need short out the data pins to allow phone to draw more than 500ma. Typically auto-chargers that comes with microUSB plug directly, such as the Samsung auto charger, will do so, asume your charger is rated to output more than 500ma.

It will be able to charge it. Keep in mind IF your iPhone USB charger max current output (5V 1000mA) is LESS than the Note's charger output, it will take longer to fully charge - but it will charge and will NOT damage the phone.
If you're looking to buy a new usb charger, look for one with the highest mA output rating since whatever device you plug into it will only draw what it needs. ie, my iPad charger is rated @ 2A/2000mA so it covers every device I own (all rated for different current inputs from 500mA up to 2000mA) and that's the only usb charger I take when I travel since I just have to switch out cables to charge other devices. On the other hand, if I only had a lower current rating usb charger, my iPad (requires 2000mA) would be out of luck.
Current output info can be found on the respective charger of your favorite device.
Hope that helps.

I am currently using my computer's USB port which as you will know doesn't give quite enough juice. I have seen a microusb charger with 5V and 2A. Will this do a job (and also not get rid of the message that i am drawing more juice than the battery is getting)?

No.
The reason for the strange shape USB lead HTC have is that it gives 9V and 1.7A - 5V isn't going to cut it, it will charge but ever so slowly and if you try to charge whilst using it you'll probably find it doesn't, it just discharges more slowly.
If I were to take an old wall wart I have here that is 9V and 2A and wire a standard micro USB cable to it, would that work to charge my flyer quickly? In other words is the strange connector necessary or just the 9V and 2A?

NO, because the fast charge requires the special connector on the HTC power cord , a micro-usb will not allow the Flyer to draw the high current.

If you're using the HTC-specific microUSB cable, the adaptor would have to provide the correct amount of power (9V and 1.7A). Most usb power adaptors do not provide the adequate amount. A little while back, I made the mistake of taking just my phone usb adaptor to charge everything on a trip out of the country for nearly two months. It worked great for everything except for my View. Even though I had the HTC-specific usb cable for the View, it was still like charging via a computer usb port. It would get the job done if I left it all day or all night, but it took forever to charge.
I really would try to track down an OEM charger. Even if you find a usb adaptor that puts out the right amount of power, it still might not provide the short amount of charging time that the OEM charger does. It should theoretically, but many users have had charging time woes when using anything but the OEM charger.

Volts and Amps - PowerFlask
From the posts on this subject it seems that the Powerflask 13000 mAh powerbank I bought today and which charges at 5.3 volt with a 1amp and 2.5 amp port won't properly charge my flyer?
Can I safely use the 2.5amp port or should I rather stick to the 1amp port.
Any advice would be much appreciated.

Folks on here have mentioned that the device (and other tablet/smartphone devices) will only draw the amount of current (amps) it needs. So using a charger with a higher amp rating is not a concern (in theory).
But I think others have debated this, and even made claims of higher volt/amp rated chargers damaging their devices (however anecdotal).
In any case, from the responses on this thread, it appears that any charger that doesn't have HTC's proprietary connector that they used for the Flyer, will charge the tablet very slowly. I just plugged my Flyer into a microUSB charger the other day (just got back from a trip, and my stock charger was still packed), and it charged extremely slowly. It was slower than I remembered it being. It was plugged in for maybe 4 hours, and only increased the charge by 10 or 15%.
PowerFlask Volts and Amps
Thanks for the feedback, much appreciated.
I ran a quick test and connected the Flyer to the battery pack.
The flyer charged from 76% to 84% in 30 minutes . I realise that such a short charge isn't a proper test but it looks promising.
I used the 1amp port and will as you cautioned avoid the 2.5 amp port.

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 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.

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.

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?

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.

Hi,
Where I charge my TF300T, the cable is too short... and when I plug a usb cable extension, no charge. A friend tell me it's possible that if I want to extend the cable, I need a USB3.0 extension...
So? What cable I need to extend the lenght of the charging cable?
Thanks!
Same. Tried multiple extention cables (though no specific USB 3.0 extenders) and no dice. It will not charge, even though other devices charge flawlessly even when I plug them into a USB extention cable (iPhone, Samsung Galaxy's, PS3 controllers, camera's, etc.)
However, the Power output of the AC adaptor for the TF300 is either 5V - 2A, or 15V - 1.2A (in contrast to the power requirements of the above mentioned devices, which are tailored to comply with USB 2.0 standards). Default power draw on USB 2.0 on Battery Charging Spec 1.1 is 100mA (1A), so that would definitely seem to be the problem. I however haven't yet had the opportunity to test a USB 3.0 extention cable, but I would assume these would do the trick, since USB 3.0 (or Battery Charging Specification 1.2) should be able to go up to 1.5A with a 5A max draw.
This thread for the TF101 shows why USB 2 extension cables don't work, and how to mod one to make it work.
A USB 3 extension cable would work too.
Consider getting the usb cable extender

if you are just looking to wall charge it, get an extension cord at the dollar store
thats what i use
extention cord will be best.
thanks for the links. have been wondering about cable length and didn't want to add another cord to plug into the wall.
does the cable change when plugged into a PC? wife took off with laptop and didn't notice when I rooted.

Did you mean me does it charge? If so then the answer is yes but not fast. It is pretty much a trickle charge when plugged in to a PC. A pc does not put out a large enough charge via USB for the tf300 to charge properly. It would take forever for the tablet to charge.
You need a 15v plug like the one that comes stock with the Transformer.
Pretty much the only thing the USB cable is good for with a pc is to transfer data.

Hi,
Where I charge my TF300T, the cable is too short... and when I plug a usb cable extension, no charge. A friend tell me it's possible that if I want to extend the cable, I need a USB3.0 extension...
So? What cable I need to extend the lenght of the charging cable?
Thanks!

Hey,
I had this similar problem with my asus TF300T, I used to have a cable +-1.5m long or longer, then I had to send it back for repair.
Couple of days later I received a new charging cable, though it was 1.30m long or less. Which is very uncomfortable when using the tablet at the same time as it is charging. So I phoned Asus Support. They told me that it is indeed possible that some tablets are sold with a smaller cable. These are most likely the newer ones.
I asked if I could send back the shorter cable (which was broken upon delivery) and receive a longer one as the one I used to own.
They told me that Asus has stopped making cables any longer then 1.30m. Though costumer service had no clue why.
They suggested me to send the cable back and to include a note in the package that I used to have a longer cable and I would like to have a similar one back. Of course I was very polite etc, and it worked!
So as Asus' costumer service says : "Asus themselves owns very few longer cables, they don't produce the longer ones anymore and moved to a shorter standard cable. Only if you are lucky you can get your hands on an older long cable".
Of course this doesn't stop you from looking for other third party cables.
I just hooked up my new Plugable 7 port USB 3.0 switch and although the speed is fine I noticed that the N3 still only charges at a lowly 450mA. Knowing that it should be capable of more, up to 4A in total, I decided to try a trick I'd been using for my Galaxy Tablets. These tablets won't normally charge from a non Samsung charger but with an inline dongle they will.
So I put the inline dongle between the switch and the USB 3.0 cable and presto, 1800mA charging current to my N3. Of course there is no data connection at that point but it's one less samsung adapter I need to keep around.
You can find the dongles here.

Umm dude use a normal charger oh i don't know the one it came with lol. I have no issue charging at 1800 mAh with standard charger. I understand you're using a port to connect other various devices but reason it's charging at that low rate is because it's USB and not seeing as AC. Just charge your phone in a wall socket and use your port for your other devices.

how do you guys get 1800mAh on a USB port?
i can't get more than 450mAh from the USB port
It only goes above 1000+ from the wall
good find...

What are these people above talking about?
Their response is irrelevant to the OP's post.
Why not try to READ the entire post FIRST, stop wasting our time reading your irrelevant BS.

interestingly enough, it seems to only work on USB 3.0 ports
i have the cable version of that dongle you are using
on USB 2.0 ports still doesn't go over 1000 mAh, but it does double the usual rate of 450 mAh
cable quality seems to make a difference too

i did if you read my post you'd understand he did a trick to where it charges @ 1800mA in the usb 3.0 port which is essentially a wall socket. he uses a port for several devices, if he didnt care that he cant access usb then whats the point in wasting a space on a port and just use the wall socket.
What if you don't have a wall socket or forget to bring your AC adapter?

maybe you but the OP stated a 7 Port which means most likely it needs a power source i.e wall charger.
1. Even with an available wall power source, a USB Hub next to your keyboard is more convenient than the wall socket charger behind the computer.
2. A $5 adapter is cheaper than the original AC transformer.
3. You might not have the AC adapter with you when you're away from home but closer to another computer
4. A coin sized adapter is much easier to pack than an AC adapter
I'll be honest, I find myself in NUMEROUS situations where I have plenty of spare USB(3) ports but no spare wall plugs. My office is a prime example of this, from a 2-gang wall socket, we have 2x 8-socket extensions and those are all full. Some of those have another 4-gang extension coming from them, again full (mostly bloody adapters, so power draw isn't actually that higher - and yes we know it's a safety risk).
My computer, on the other hand, has something like 12 USB ports, of which about 8 are in use. Makes sense to me.
As someone pointed out the 7 port USB switch does have an AC adapter that provides 4A total. It's not that I don't have AC outlets at my desk, I have 10, but they're hidden behind a 400lb desk and not the easiest to get to whereas the USB switch sits within arms reach and is always on and available.
I also have several AC outlets around the house that have integrated USB charge ports. Given the number of devices that charge from USB these days these are very convenient but won't charge a Galaxy Tablet at all without the adapter. If you travel you will also find these at a lot of airports now too, usually located on the pillars in the waiting area.
In my experience at least it's a lot easier to find a spare USB port than an AC outlet, and that's assuming you have your charger with you. The adapter plug just helps you extract more charging current from what's available.
