[Transformer TF300T General] TXKSSnapper:
The tf300 charger is not 5V, its either 12V or 15 V (can't remember which). This is why you see nothing. if the only difference was the current (1A Vs 2A) You would still get a charging notification, it would just take longer. The difference in voltage means It should not be able to charge at all off of a normal usb connection.

Saw that guy on ebay for $13. Think it would work?
[Transformer TF300T General] BierLiebHaber:
the tablet gets charged on a normal usb port it just doesnt tell you its being charged and it take quite a while to fully charge up
[Transformer TF300T General] TXKSSnapper:
I haven't seen it charge any when i've plugged it in to my computer via usb. but it could be that I don't have the patience to wait long enough.

---------- Post added at 01:07 PM ---------- Previous post was at 01:05 PM ----------

yes, but it will be slower than with the charger it came with. that charger only has a 1.2A output as compared to the 2A of the stock charger.
[Transformer TF300T General] sark666:
Everywhere I read, people have said that it does not trickle charge at all via usb. Can someone confirm this?
[Transformer TF300T General] Jake2kOne:
Okay, I can confirm that the TF300T charges at 15V/1.2A.

Both, the tablet and the dock uses 15V. None uses 5V.

I was confused because it's USB. For this purpose it can transform to 5V/2A. But this is not for the tablet.

So I think it's not possible to charge it on a normal USB port.
[Transformer TF300T General] psjw12:
Has anyone tried using a USB extension cable? I tried one on my Tf300 and it wouldn't charge, no matter what the table arrangement was. It would only charge off its own charger and with only its own USB cable in the USB charger.
[Transformer TF300T General] fingery:
At a guess, i'd expect it's because the ASUS charger outputs 15V so the charger or cable will be wired differently to a normal USB lead in order to prevent blowing normal USB devices if you connected them.
[Transformer TF300T General] stinkyjak:
USB 3

I can't remember where, but I read that this needs to use USB3 cable. Sorry if this is not the case.
[Transformer TF300T General] Jake2kOne:
I don't think USB3 is the key here. ;)

It's a Asus system plug and not just a Micro USB or something else.
[Transformer TF300T General] psjw12:
I believe the voltage wouldn't make a difference, only the current will. But if it was wired different then how does it seem happy with being plugged into a PC? This is strange...
[Transformer TF300T General] TXKSSnapper:
As I've stated in one of these threads I've never seen it register charging or "trickle charge" through a PC.

Kinda dumbed down engineering explanation:

Voltage will make a difference. Following Ohm's Law V=I*R (Voltage = Current*Resistance) The Tablet/Battery Is our R and it is constant. Therefore if you take the normal adapter you get 15=2R. If you switch this to a normal USB, you get 5=0.5R. R=7.5 in the first scenario, R=10 in the second scenario. Because R is constant it is impossible for it to equal two different values.
[Transformer TF300T General] Neuralgia:
Anyway, I started the thread to find some answers... Now that I know it's not only mine, but a behavior of all Tf300 tablets let's here some solutions

Any generic brand that works? I don't want to send $30 in one of these if you I can.

It's dumb but I don't like Asus decision here
[Transformer TF300T General] rwniel:
If you need to extend the length of the standard Asus cable, then that is where USB 3.0 over 2.0 comes into it (- you need a USB 3.0 extension cable as 2.0 ones don't work). In terms of chargers, there are a few options mentioned in the Prime accessories guide thread (mostly for in-car charging solutions) ; http://xdaforums.com/showthread.php?t=1377669 . I would imagine it's the same with the TF300. As a number of commenters have mentioned output voltage and current is primarily the main factors. Other usb chargers that supply too low a voltage or current tend to only work when then tablet is completely switched off (i.e. not just in sleep mode) and at too low a rate to really be practical.

[Transformer TF300T General] pakure:
Just a doubt... Would any asus ee pc or notepad charger work?... (my tf 300 comes in tomorrow)
[Transformer TF300T General] supersoulfly:
I got the manual here:

http://dlcdnet.asus.com/pub/ASUS/EeePAD/TF300T/TF300T_MANUAL_en_20120423.pdf

Says that if you want to charge it via your computer USB port (page 10) that you need to make sure your tablet is turned off. So those not getting a charge may have better luck if they turn the tablet off. It states it will also take a much longer time to do it that way.

So, it looks like it should work. Just need to shut down the system before hand.
[Transformer TF300T General] slinker1:
Coming from the tf101 world.The tab requires 12 volt min to switch the charge mode while on,it will trickle charge while off.YMMV Real long thread under the tf101 area tf201 was the same I doubt it has changed for this guy. BTW loving the tf300 a very nice upgrade from the tf101.:D
[Transformer TF300T General] superflysocal:
The touchpad uses a 2A charger. Can anyone see if it will charge the tf300?
[Transformer TF300T General] sark666:
Can someone confirm this? Everywhere else I read said it doesn't work. Also how much it charged per hour if you can. I'm thinking on returning my acer 510 and this was one thing I didn't like about the asus tf 300
[Transformer TF300T General] EndlessDissent:
I can confirm this. It's in the user manual. The tablet must be off to charge via USB.

Edit: I'm pretty sure I read somewhere that the a510 is the same way with USB charging.
[Transformer TF300T General] JoelParke:
I can verify that a usb extension cable stops it from charging! too much resistance! I use an extension cord instead.
[Transformer TF300T General] psjw12:
Today I noticed if I put in a USB extention cable or a non standard USB charger, although the device doesn't charge it still 'reacts' to the presence of a charger. If the sceen is off and then plugged in, the screen will turn on. I've not tried to run it off a lower power USB to see if it still sends a low amount of power to the tablet.
[Transformer TF300T General] cheedear:
confirming that it does charge via usb when the screen is off. It took nearly a day to get from 5 to 97%.
[Transformer TF300T General] SilentStormer:
Yeah, i was trying to root mine on friday but it wouldnt mount in windows (and thus not show up in fastboot) and it also wouldnt charge. While i have been away from my comp, I have realized that the ports I was trying to plug it into were on the front of the PC and were probably not directly mounted to the motherboard and thus not fully powered. When I get home tonight I will be trying plugging the tab into one of the USB ports in the back of the PC which are directly attached and thus fully powered (i know they are attached, I open up my PC frequently to swap and replace components.)

ill keep you guys posted. Try plugging it into a port that you know FOR SURE is a powered port.

TF300 uses USB 3.0 not 2.0

The TF300 uses USB 3.0 not 2.0. The pinout in the cabling is different. So no, a USB 2 extension will not work. However I can verify that a USB 3 extension works just fine. I have my 300 plugged in via one right now and it has been fully charged using it.

I carry a 10' extension with my charger in lieu of an extension cord. Works well. :)
[Transformer TF300T General] sark666:
Hmm, are you sure? I thought I read others saying it'll charge over usb2.

So it's only usb3?

[Transformer TF300T General] chili_red:

They work fine for charging also, they are a foot longer than the OEM ones, and seem to be really well made. Now I just need to find a charger that doesn't cost $25.
[Transformer TF300T General] Neuralgia:

I'm also looking for a charger that doesn't break the bank
[Transformer TF300T General] Nomad692000:
I just built a new a new system w/Asus Maximus V Gene in the bios it has a setting for usb charging. Its for the usb 3 connections, it charges pretty well. Not quite as fast as the charger but faster than when the setting is off. I know Asus , Gigabyte an MSI has this feature on there 68 an 77 chipset boards. Don't know know if any of the other Mobos has this feature, I haven't worked on to many of the other boards

Can anyone confirm that an TF300T will charge with an Car Charger and an USB 3.0 cable?
[Transformer TF300T General] adrhodes:
Well... when your tablet charging in less than 3 hours you can't complain.

Get a new charger :eek:
[Transformer TF300T General] Neuralgia:
So no non Asus options for a charger yet?
[Transformer TF300T General] krhainos:
Charging the TF300 (or any Transformer) is easy!

The Transformer will charge when it sees 12V to 15V on what's typically the 5V pin.

The Asus charger will output 15V (earlier units were 12V) when it senses the USB 3.0 pin 7 is grounded.

Also, if you'd like to build your own power supply -- get any old female USB connector, and send 12V to 15V on pin 1 instead of 5V, and you've got yourself an Asus Transformer charger. Just don't plug anything else into it, since there's no safeguard to prevent 12-15V going into a 5V device. I've painted mine orange so I don't mistake it.

So if you use the existing 12V rail from your main power supply and send it through the 5V line, the tablet will charge and communicate over USB at the same time.

Make sure you isolate the +5V from the motherboard USB, or else you'll have blown up your USB controller (I think they're fused, but I'd rather not try ;D)

EDIT: I noticed someone mentioning a car charger -- the output on most cars are labelled 12V, but I would not recommend attaching this 12V straight into the tablet before cleaning it up since the voltage can vary and swing wildly based on a multitude of things.
[Transformer TF300T General] dragonnn:
BTW - Can I use ASUS charger to charger other USB 5V devices? Like my Ace?

Wysyłane z mojego ASUS Transformer Pad TF300T za pomocą Tapatalk 2
[Transformer TF300T General] krhainos:
Yes! The charger that comes with the Transformer is dual-purpose. If you plug in a Transformer tablet, it'll output the 15V to rapid-charge your Transformer. If you plug in a USB device, it'll output 5V (up to 2A capacity) to rapid-charge your USB device.

If you're wondering how it can tell the difference, Pin #7 on the USB3 Transformer cable is grounded -- this is how the charger can tell the difference between a Transormer and an ordinary USB device.
[Transformer TF300T General] wwphil:
Thanks for this info (and to anyone else reading this, I confirm it's accurate).

I have 2 coworkers with TF300s and they were telling me it doesn't charge on anything else than the Asus adapter. I was SO skeptical about that (and I was right to be), so I measured the current drawn by a TF300 off a whole bunch of different USB ports and chargers.... And it does charge, but the available supply is not always enough to power the device and charge it simultaneously. But it still works. This is not a very good move by Asus if you ask me but what can I do...

I didn't go as far as finding out about pin#7, very nice to know, thanks for that info.

My only remaining question (since none of my coworkers have rooted their tablets) is: Will a custom rom recognize any USB adapter with sufficient power to not still be "discharging" on this tablet ? or is the recognition hardware based ?

With a Samsung 5v/1A, the tablet was reporting "discharging" with a current of +115ma (which means it's charging, when I unplug it, it goes to -350ma or more on the next measurement)

So You're Saying There's a Chance

So...I've been wondering (why I'm on this page)...you guys are saying the TF300T has the same charging connector?

Anyone done any looking around to see what other devices/accessories made for iPad 2/3 will work with the TF300T?

Of course, the market is flooded with iPad 2/3 accessories--this might make things quite interesting if we found out that speaker systems, cradles, keyboards, other stuff, for the iPads will work with the TF300T.

(I, for one, will be making a trip over to my local Big Lots, har har).

Thanks.

I looked at this thread...

Can anyone point me in the right direction to how I can get TMOUSA working on the rezound? I might buy this phone in a week...

Is there a specific rom I need to flash to get TMOUSA to work? Or is it Flash once, done?
[HTC Rezound] con247:
Either install JoelZ's Sense 4.0 rom and use the GSM patch and then just toss your sim in.
[HTC Rezound] nitrogen618:
Is it possible to use other rom and than use GSM Patch?
[HTC Rezound] jett1217:
Miui
[HTC Rezound] con247:
There is a Stock ICS Sense 3.6 patch he made. But you MUST be on ICS.
[HTC Rezound] nitrogen618:
Is it possible to use any rom, and use the GSMPatch?

The reason I'm getting this phone it's because it can work with TMOUSA, and it has a 720P display..

Also, I can't find any OC kernels... Is there any kernel for rezound that OC to around 1.7/1.8Ghz?
[HTC Rezound] con247:
No stable GB kernels that overclock and there are overclock ICS kernels if you search. The rezound is really fast at stock clocks though. There isn't much reason to OC.

Not sure why you are so opposed to using the roms I mentioned. Joel's sense 4.0 rom which the GSM patch is meant for is by far the best rom.
[HTC Rezound] nitrogen618:
Oh, I love his roms, I'm just wondering if I can use other roms. :p

Sorry, I'm new...

I'm from the LG G2X, thinking of getting rezound.

Is it hard to S-Off? On a scale of 10 what is it out of?

Can I flash any kernel/any rom using the HTCDev method(S-ON)?

Just to confirm, the GSMFix is 100%, SMS, Data, Call. Right?

Sorry for many questions, I want to make sure of everything before I buy this phone.
[HTC Rezound] con247:
LOL any phone would be an upgrade from the G2X.

S-OFF is probably a 2 on a scale of 10. It looks WAY harder than it is.

You can flash any kernel/rom with S-ON, but it is not a convenient. I recomment S-OFF immediately. It makes it much easier to recover your phone too if any issues arise.

GSM Fix is 100%. You will get T-Mobile 3G, texts, calls, etc.

However, since you are on tmobile, I would recommend a One series since you are a GSM user.
[HTC Rezound] nitrogen618:
I don't want the One S, Pentile display, battery, no SD.

The one X is too expensive. ( Rezound is about $300, One S is about $425, One X is about $550)

So this will work with TMOUSA 3G, or is it just EDGE?

With S-Off, I can just flash kernel, and roms with CWM right?

^^ Can't I flash roms and kernel with S-On on CWM?
[HTC Rezound] con247:
Don't use CWM. Use AmonRa or TWRP.

Don't worry about what S-OFF allows you to do. Just S-OFF the device. 3G should work fine as well as edge.
[HTC Rezound] nitrogen618:
O:

I got used to TWRP in the G2X...

Hm, I'll see you guys in a few weeks! ;D

Anyway, I can't find any OC ICS kernel.... Can you link me, if possible?

The only thing I'm reluctant about the rezound is the thickness.. :|
[HTC Rezound] GreenXSniper:
The thickness isn't really that bad, it's a beautiful phone IMO.
[HTC Rezound] palmsole:
You want thickness get the extended battery for all day power users. With an extra extended battery you can pretty much go anywhere and not worry about losing power. The phone still fits in your pocket and chicks dig it ;)
[HTC Rezound] Snuzzo:
Don't worry about an OC kernel. You won't be able to control the scaling properly. In my use leaving kernel as is provides the best battery life.
[HTC Rezound] nitrogen618:
Because I'm wondering the Sensation,Amaze, TMO SII, Skyrocket, have OC... They're the same processor... O_O
[HTC Rezound] con247:
The phone didn't come till November. Gb was basically dead at that point. Stupid to make kernels for it. We still haven't received the ics kernel source from HTC. So our options are limited until that happens.
[HTC Rezound] nrfitchett4:
the one s is not pentile display and from what reviewers have said, it has the best QHD screen right now. Just remember that a 720p screen sucks way more battery than a QHD. I would do the one s personally instead of trying to rig a verizon phone on t-mobile. Pretty sure the one s is hspa 42 (at least 21).
[HTC Rezound] con247:
I agree 100%
[HTC Rezound] tekhna:
The One S is pimptastic, I'm not sure why you'd get the Rezound over the One S. As much as I love my Rezound.

On gingerbread I was able to click Youtube links from any application and launch them using the youtube app. I was prompted once to do so and every time thereafter the app would launch.

Now on ICS, i never once got the prompt to chose internet or youtube app, it just launched every youtube link using the browser which i detest.

Does anyone know what option/default i have to clear to get my app back as the default for links?

I tried clearing defaults for the browser and any apps that i usually click youtube links in to no avail.
