So I've been thinking - the TF has a power requirement of 5V/15v at 2/1.2A, which is the same requirement as the ipad. Really wouldn't see any reason why this wouldn't work so long as the charger has a usb port and you use your OEM cable.
Much easier finding chargers for ipads than the TF, for now. Have some home and car chargers on order and will post results later.
TF's charger requirement is 15V.

That was the first time I plugged the Transformer in. I didn't even get a full charge out of the thing.
The transformer charger can shift between [email protected] or [email protected]
I have confirmed with my multimeter that the voltage is 5V when charging the transformer
The [email protected] is to charge the keyboard dock, but do not own one to confirm
You can use other chargers, its just Asus's stupid smart charger makes the charging indicator comeup when using the official charger, it also chargers faster, need someone with an electrical background and an oscilloscope to probe it out
I have been meaning to do a test on charging times with different chargers
Overall, as long as the charger is [email protected] under (ex. [email protected]) It will charger, the Transfromer will not show it, but if you check on it the percentages goes up
Ipad chargers are at [email protected] so give it a try
looks like the ac adapter is available online...

Wonder if it would be safe to charge iPhone and iPad through Asus "block".
I plugged my iphone 4 into the Asus block and it seems to charge fine. How safe it is, is another question entirely, but I can confirm it does charge the phone, and the thing didn't spontaneously explode or anything

I had reservations on getting the dynex charger but I hate only having charger for any unit I have. I bought it as a backup and cord lenght...lenght is very good. I received the transformer the next day from Amazon and saw the shortness of the stock cable. Brought out the dynex charger set it at. 11 volts and plugged it in and Viola...charges. 11 volts is lower then 15 but it still managed to charge from 29 percent to 100 in a acceptable and fairly good pace. I now use this charger over the stock because the stock charger gets really hot if used for a long time and I really don't feel comfortable. Using it.

I noticed that too but when I plug it in at night the next morning it's cool. I guess it heats up only when actively charging. Towards the end it should go down to trickle or no charge at all.

So my charger met with an untimely demise. I am unable to get my hands on a replacement one at the moment.
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)?
I use the charger that came with my Evo 4g. It needs to sit overnight, but it charges to green.

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.
Thanks

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.

Have you ever wondered how an EP800 compares to an EP850, or an iPad charger? I have. Reading the comments on the forum there is a lot of subjective opinion, but little in the way of facts. With this in mind I decided to make a little app to measure how long it takes the phone to charge from 20% to 80%.
20% was chosen as the start because readings below this have a high uncertainty
80% was the ceiling because the Xperia shows down charging somewhere around 90% to protect the battery.
I wanted to ensure I was measuring the charger at its peak output.
So far I have done 3 runs:
EP800 (rated 850ma) with normal USB cable, 8845 seconds (est 427ma)
HTC B250 (rated 1000ma) with normal USB cable, 7910 seconds (est 477ma)
Unbranded (rated 1500ma) with "data" cable 3120 seconds (est 1211ma)
My current suspicion is that the charger is not as important as we have previously believed, it could be all about the cable. I will run some more tests over the next week using the same charger with different cables.
In the meantime, if anyone wants to give it a go, my app is available here
https://play.google.com/store/apps/details?id=com.vexedbadger.chargertimer
(once Google gets around to approving it)
and my latest results are here
http://vexedbadger.com/?page_id=97
But I will keep this thread updated until I reach a satisfactory conclusion.
I am also eagerly anticipating the EP851. I wonder just how good its boost charge feature is. Could it simply be a normal 2A charger with pins 2 and 3 bridged?
If you do give the app a try, post your results here.
-----------------------------------------------------
For newcomers to this thread I believe I have made an important discovery. I ran a test using a HTC B250 1A charger. I did it first using a normal USB cable. I then repeated it using a USB charge cable (2 wires, no data lines) and got these results
Data Cable, 7910 seconds, est 477 ma
Charge Cable, 3530 seconds, est 1071ma
In other words the cable you chose to run between your charger and the phone is absolutely critical in determining the charge speed. Here I have observed over a 100% speed increase.
Using the supplied EP800 (850ma)
Data Cable, 8845 seconds, est 417ma
Charge Cable, 5170 seconds, est 731ma
Again, a huge difference.
Oh, and the BlackBerry Playbook charger is a beast.
I have just done a run with the BlackBerry Playbook charger HDW 34625 (2000ma).
20-80 in 2875 seconds. That means approx 1314ma output. An estimated 0-100 in 1hour 20 minutes.
I have a new charger of choice : )
Nice find, but is it good to charge the battery like that ?
I suspect you're correct OP.
I charge mine with a 1A iPod charger with an x10 cable + 8M Extension cable(sockets only on one side of the room), with that charging is pretty slow. Tried it without the extension but it wasnt noticeably faster. Then one time I used a 15cm USB Micro cable from an unknown device on the front USB port of my desktop(500ma maybe, probably less) and it was insanely fast.
So yeah, think its the cable.

My guess is that Sony know a thing or two about batteries. They control the amount of charge passed to the battery. A very conscious decision is made at 90% to reduce the power flow to the battery. I am happy to chuck as much power as I can at it.
Also remember that Sony are about to release the EP851, a high speed charger.
If I remember correctly if you connect only the power cables within a USB cable the maximum you will get from most devices is 500ma. If you connect all 4 cables as a regular USB data cable, the 2 devices communicate and then the phone will ask for maximum current from the USB host. This could be several amps. This is why there is a variations in charging times. Try several different cable on the same port, then try them all again charging from different hosts, ie. OEM USB charger, computer usb port, other USB chargers.

I think you are close top the answer there. The USB 2.0 spec says 500ma per port. This spec was written long before charging smartphones via generic USB cables became the norm. Some manufacturers now offer high ampage ports on the motherboards. I know Apple does, my aBit one does and a few gigabit ones do.
The phone tries to detect if it is being charged from a computer USB port where it is capped at 500ma, or from a power supply that supports more than this. There are two conventions that I know of. Apple puts a resistor between pins 2 and 3 (the data pins). IF this resistor is present hen the device charges at full power. HTC (and a few others) rely solely on pins 2 and 3 being bridged. I think this is the USB standard as well. Some batter apps will tell you if the detected charger is in AC (high ampage) or USB (capped) charge mode. The speed difference is pretty dramatic.
Some cables come with pins 2 and 3 pre-bridged. They are no good for syncing but great for charging. I am running some tests with one now.
Interesting app, I have a bunch of random USB chargers and such floating around. I use as my standard charger the 850, but I have wondered if I can get better charge from the piles of other chargers floating around.
I also have a BlackBerry bold charger (direct connection to phone via fixed USB cable) do you think that could perform better? I guess I will test it out first.

No. The second one means 5A, if you bothered to read the specification whitepaper.
And my post explains clearly the difference between 1.5A and 5A current:
1.5A for "UNCONFIGURED DEVICES", and "HIGH SPEED COMMUNICATION WHILE HAVING A CURRENT UP TO 1.5A"
5A is the MAXIMUM ALLOWED CURRENT.
I noticed a lot of people want a fast charger for the Note. This charger is for the Touchpad. I have this and it works really well. It charges faster than the OEM charger that came with the Note.
Not to mention, it is on sale right now for less than $5. Go grab one. From past experience, I used this at 15% battery life and charged for an hour and I was back over to 80%.:victory:

Yes, it is a micro USB cable. One end is USB and other is micro USB. The cable length is longer than most phone cables. I haven't measured it, but from my plug to my desk, I still have excess cable compared to the original one from the phone.
Thank you, getting one!

That 1amp is the output of the charger which forwards the current to kernel of the device... NOTE can only intake 1 amp current... ( remove your battery and read the dam sticker :thumbup
Even though you will supply 2 3 4 5 amp... The maximum in would be 1 amp ONLY...
SECONDLY, micro usb cables have a restriction of carrying current... They cannot pass more than 1 amp current successfully... Therefore galaxy tab series does not come with micro usb slots....

It has been discussed, but it DOES charge faster than a conventional 1amp charger. If you don't have the charger and have nothing to compare with, then I don't think you can say it does not work.
Go check FCC about the charge. Also, the cables provided DOES carry a 2amp charge. Our note can handle fast charging but throttles down to a slower charging rate after 80%.
having a micro usb slot or not have a micro usb slot has nothing to do with the current it can handle.
Ipads and Iphones have the same connector but yet one has a 1amp charger and the other a 2amp charger.

As an HP TouchPad owner, I can confirm that the cable provided with the charger are 'special'. My TP will not charge with any other MicroUSB cable connected to the official charger, the same cables which won't charge the TP will charge the Note. (I also own the HP touchstone dock, which the TP spends most of it's life sitting on.)

I have four different wall chargers, including two of this HP barrel adapter (one that came with the TouchPad, one that came with the Touchstone). With the supplied cable, it does charge the TouchPad very quickly. From webOS, the net charge rate is about 1.6 A with the screen on, so probably close to 2 A coming out the USB port.
However, when you plug a Note into this charger, the Note will still only draw 1 A. I have other AC chargers that are also able to supply 1 A to the Note, so in that respect this HP charger isn't anything special. However, it is only $5, which is a good deal.

I've found that the microUSB cable that comes with the Note, when paired with the HP TouchPad's AC charger, will supply 2 A. At least, that's what the OS reports: /sys/devices/platform/usb_gadget/current-mA shows "2000". Plugging the TouchPad into the Note's AC charger shows a value of "900". Plugging it into my laptop's USB port drops that value down to "500", as expected.
I bought two a week ago off Amazon for $10 each. $5 each with free shipping is a steal. I picked up three more. Thanks for posting this deal. I get 1A charging with either the stock charger or TP charger. I like to have a few extra chargers to sprinkle around at home or work (for my Note and the other devices I own that charge off USB.... including a TP).

Yes, it is a micro USB cable. One end is USB and other is micro USB. The cable length is longer than most phone cables. I haven't measured it, but from my plug to my desk, I still have excess cable compared to the original one from the phone.

When you charge your phone using this HP microUSB cable, do you have issue with NO DEEP SLEEP when unplugging the Note from the charger?
There has been issues reported in XDA where, depending on the USB cables used to charge the Note (connected to computer OR power charger), if you unplug the Note, it will not go DEEP SLEEP, causing significant power drain.
This does NOT happen when the Note is charged using the cable that came with the Note.
Download Current Widget from the play store. Add widget to home screen and you will realize that your phone is not charging any more than 1 amp as designed.
Try the usb out from your pc and you will see about half an amp.

I have the galaxy tab brick charger the HP touch pad charger and my note charging brick....the touchpad charger works faster...but I feel like it doesn't get fully charged..seems to die faster?. I used the galaxy tab brick...slow to charge warms my phone up nicely...I'd stick with the original note charger.

I charge my Note overnight using my Touchpad's MicroUSB cable plugged into the Samsung charger, and I don't experience any difference in power drain.
Where is that post from the guy who put all these petty arguments to rest with scientific tests of all the various options and results??
Good lord people it's a charger for a phone .. no need to get so heated!
(unlike my stock charger.. which gets very heated!)
great price!!!
ordered 3 of them
the price is way cheaper than just a single micro usb cable shipped from other stores
i have 3 already
1 at work, 2 for home.
definitely faster than OEM. I charge overnight, no issues. had for around 5-6 months now. and i can use the phone while charging.
fact is that it DOES charge faster.
i recommend it
WOW***
Great price I bought 2!
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.
