Charger Overheated? - Asus Eee Pad Transformer Prime

So, i put my TFP on the charger last night.. it was around 5% battery. I check on it now, and its completely off, the charger is hot and smells like burning plastic and my TFP is dead.
I'm not getting any response when i try plugging in the USB to any USB to 110V charger..
Anyone else experience something like this? I've had no problems with the device so far
-edit
anyone have a support number i can call as well? ughhh

do you happen to know if its the same charger for the tf101 and tf201?

From what I've read it's the same charger.

RMA it right away or return it to the retailer you bought it at it will be faster than Asus

They are identical.

Also: Besides it being USB 3.0 (Requiring a special charger), the Asus chargers are chipped to recognise Asus devices and deliver 15v verses the standard USB 5v so that they charge faster. The TFP wont charge at all on only 5v. It's the same reason it wont charge from your computer.

wrong again the dock pulls the 15v at 1.2A the reason it will not charge or chages very slow is your usb is outputting like 500 mAor less without the flow of electrons which current is it will not charge very fast at all! 5v is fine for it! but the charger charging at 5v pulls 2.1A
the tablet also trys to pull more current when it is almost dead! so try to keep it above 20% to avoid this

Ok, my Gigabyte motherboard puts out 2.5A specifically with tablets in mind. If it was charging, my lockscreen would say "Charging..." on it, which it does not. No need to be a rude know-it-all with your "Wrong again..." attitude. Just trying to help out here.

The Prime will charge on a USB but it has to be turned off. I've confirmed this and the manual says this as well. As far as my charger goes it gets warm but not hot or smells. One thing I do when charging is turn off the tablet.

Ok. That seems correct. Thanks for verifying.

It does take a lot longer to charge on the USB though. I can go from 20% to 100% in a couple of hours on the wall charger with the Prime turned off. On USB and the Prime turned off I was at approximately 15%, went to lunch and did some other things, came back about 1.5 hours and when I turned the Prime back on it was a little over 50%.

Might be faster on my Desktop since I have the high power USB ports. I will try it and post results eventually.

ipad usb charger for transformer

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.

best buy has a usb charger that you can get, its called a dynex ultimate charger for cameras and camcorders. its like 30 bucks and charges at 11 volts / 1.5 amps. it works great. I had to get one when my usb charger melted. Its the only one that I have found to work. I tried around 30 of them lol

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

Cool, at first glance it looks like the cable is longer because of how many times its looped around. I just wrapped my cable around and looks close but not that exaggerated, you think Asus differed the photo? Lol

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.

12V car charger!

http://androidforums.com/asus-eee-pad-transformer/382444-bargain-car-charger-inverter-uk-5-a.html
Jason71 on AndroidForums.com said:
Hi all
Long time Android addict and just got myself a transformer at the weekend. I have been puzzling the best way to charge it in car (read the threads on the subject) when I happened to wander in to Asda and spotted a mini 75W 12-230v power inverter on sale reduced from £20 to £5!. They are exactly the same as ones that sell on Ebay for 2-4 times that price out of Hongkong e.g.
12V to Mains 75w Car Van Mini Power Inverter Adaptor | eBay
I bought one and tried it on the way home from the store with the Asus AC charger and the transformer and it worked perfectly.
As a bonus it has a usb port built in not only rated at 1000ma but wired to be recognised as an AC charger (many arn't) which means it will do full speed charging on an android phone. So it should supply enough current to charge my HTC Desire even when using it as a satnav (many don’t). The only downside is that the flange on the Asus mains charger covers the edge of the USB port on the inverter so you cannot use both the AC and the USB at the same time without trimming the flange on the Asus a little.
Anyway I thought this was too good a deal not to share it with you guys.

The ASUS AC charger is normally working very close to it's limits when running off fairly stable AC mains. Running off this modified sine wave poorly regulated device may be enough to push it past its limits. If you want a good mobile solution that you can use for the TF and other small DC devices, search for the thread by Devcake where he lists options and actual reviews.

Does your TF indicate charging, e.g. with Dual Battery Widget, using this bullet charger?
E.g. If it outputs 11V-12V it should indicate charging on the TF, but if less than 11V, say 5V-10V, it would trickle charge only (no indicator).
I got one from same guy, and it does not work. I measured 2.8V output.

Mine arrived today. I hooked it up to 12v and tested the pins, got 2.8v. Then plugged i transformer and waited about 20 seconds. The transformer said it was charging on AC. I havent checked to see how quickly it was charging, but it gave the charging indication with the screen on.
EDIT: Tried it on another vehicle and now won't charge. Weird!
Any update to this working?

I use this one for my phone (HTC Desire HD). It should also be okay for the Transformer, right?

This one arrived today, there is one small issue with it, when you first plug it in the lighter the blue light gets bright and the asus orange light goes on and eventually green showing also the charging symbol, but if you unplug the cable from the charger and plug back in, it wont work, you have to unplug the charger from the lighter and plug back in. weird... But it works

sorry, I don't think it will work.. the transformer needs 15V to charge, that one only is a 5V charger. i'd cancel my order.
OK, let's go over this again. The TF will charge with 5V at 1.5 amp but take forever to do so. The amps has nothing to do with it. It is the volts. If you feed the TF with 11V to 15V at 1.5 amp's or more it goes into the fast charge mode and charges in about 2 hrs. Anything that says 5V will charge the TF if you have several days to wait. If you have just hours you must charge using 11 to 15 volts at 1.5 amp or more to charge with. This is what the original power supply is doing. Please look at the specifications printed on the original charging brick. Note that it has dual outputs 5V and 15V if you plug your phone into the ASUS charger the charger is smart enough to know not to output 15V however when you plug in the TF the charger outputs 15V to charge the TF in the speedy mode.
Please read over "Dvecakes" thread for even more details and items you can use to charge the TF on the go and at home.
Hope this helps.

[Q] HELP Transformer Prime Won't Charge via wall plug

My 3 day old prime will not charge via the power adapter, I tried bending the prongs, I tried freezing it thinking there may be a thermal cut off switch.
The cable i snot bad because my PC and MAC both see it via USB, I just can't get it to charge.
Any ideas would due greatly appreciated before i send it back to New Egg. It is a C Series Serial Number.
Thanks
Check the power adapter. Mine had separated a little from the "brick". Once I snapped it back together it worked. My experience.
Same thing for me.. PC recognizes it as a media device, but will not charge with wall charger. Wall charger works with my HTC Phone, so it works.
I don't think it has anything to do with the latest update, since the Dock wont charge either, and there's no OS in that, right?
There have been a lot of people remarking on the wall charger going dead. Contact Asus or bring it back to the store.

How can a charger which came with the Tablet give an output power which is not enough to charge the Tablet which it has been made for? That does not add up.

Can it be something with the newest firmware update? I read something about that on another Android forum, but that was for the old Transformer.
But still, why then wouldn't it charge the dock, since there's no OS on there, is it? Would not have anything to do with a firmware update?
This charger crap is stupid....mine stopped and it wasn't even plugged in....freezer fixed it though

I recall reading somewhere that the Asus charger can put out 5 volts, or 11+ volts (11 + is required to charge the prime.) It could be that it is charging your phone because it is supplying the 5volts, but it may have something wrong with it and it is not putting out the 11+ volts required to charge the Prime.
My first Prime had this EXACT problem where it would no longer charge, and I returned it for a second one while under the return window- I believe the Asus chargers are just not very good and they are prone to failures.
When I received my second prime, I went out and Purchased a Radio Shack 12 volt wall charger, with a USB adapter that plugs into the transformer prime charging cable. The Radio shack charger is much better for me- no failures and it does not event get warm while charging- the tablet has worked fine for the last 2 months so far without issue.
If you are interested in the radio shack charger, see other posts made by me for specific part numbers. you can order online, or pickup in store at most locations.
Asus needs to do something about these wall chargers. They need to be re-designed so that they do not seperate, and do not require cartridge based adapters- this is a huge problem.
The primes biggest issue with " Prime reliability" is the wall charger IMO- More failures and returned units for this than anything else.
I love my Prime, and the radio shack charger works for me- good luck: and check all of your other options first before returning your tablet... there is a good chance it has to do with the charger itself.

Same over here...my wall charger broke inside a few weeks ago when i pushed the usb into it the wrong way so when i pulled it out it took the plastic surrounding the pins with it. ..the plastic was broken but there was still enough of it left to push it back in thus covering the pins the way it was...and now ( 2-3 weeks later) the charger stopped working and the cable no longer detects a PC when plugged in and the prime doesnt detect a PC either..the screen turns on when i plug the cable into the charger or PC but thats all it does...no charging indication or Sync notification..nothing. SO im hoping its the charger as thats what im going to buy on Friday with the cable and if not then I guess this tablet went from a nice fast beauty to a dead POS really quick..lets see....oh and ive tried the freezer, detach the charger methods and pushing the pins out on the port and its still 1 BIG FAIL...hoping for the best =) ...running icylicious BTW and this is a nice themed ROM..big ups to the dev
I went to find a new charger, but a 15v wallcharger was impossible to find. So I was lucky and found an original Asus charger (50 f'in euros), so I bought that.. But still, when I plug it in, the charge-light on the dock is blinking, and the tab wont charge.. it turns it self on when I plug it in, but then I get a picture of a battery and then it shuts off....
Is the Prime broken, or is it still something to do with the charger?

Is the Prime broken, or is it still something to do with the charger?

The Prime will show the red battery once plugged into a charger when its completely dead..i would leave it charged for an hour or 2 and try turning it on again...it SHOULD work..if it doesnt then yeah I would say its the Prime unless that charger doesnt work either...at that point I would probably give up on life J/K!!!
Same problem here. The adapter stopped charging my Prime. I was able to find the original Asus Transformer charger at a local Office Depot (last one in stock). That works fine and charges. I don't understand how that charger can just fail like that. If there's a fix please post. TIA
This just happened to me too. I am trying the freezer method, but why are we not seeing anything out of ASUS about their crap charger???

These problems have been around since the TF101 as the 101 & 201 use the exact same charger. It evidently isn't a big enough issue to address.
I finally found a store where they were selling the charger (Office Max) and they only had 1 charger left! ..This was after I called bestbuy,hhgregg, brandsmart, radioshack...I even went to the ASUS ordering site and they were all out...Amazon was out, Ebay was my only bet or so i thought..I called OfficeMax as a last resort as I didnt even think about that store at first. Now My Prime is back to shape..I may need to leave it charging for a little while after 100% as the battery is draining a little faster than usual and Ive been "trickle charging" for a week already. Plus this new charger is only a 3FT if that so the cord is shorter than the 6ft I had originally with the Prime. If you guys are looking try Office Max and ask for the Asus Transformer charger not the Asus transformer PRIME as majority of all stores dont got it, never have and probably never will. Good luck!

Charging prime dock through usb

My Prime ac adapter stopped working (the cable works fine) and was wondering while i wait for a new charger if the dock can charge through the pc. Any help or suggestions are appreciated

I know that the prime can be charged by a computer,but I never tried with the dock,to charge your tablet you must turn off it or put it in to sleep...

May I ask how? Everything Ive seen and read says that the usb doesnt put out anywhere near the power needed.
The tablet can charge on the lower 5v, but its a trickle charge and it doesnt show the charging icon. Anyone try this with the dock? Mine doesnt work but mabe theres a way...

The dock does not charge from USB.
As far as I know the Prime can indeed be charged by USB only when it is off, since when it is on it will probably consume more power than the one received from USB
For the Dock, I really dont know if it may actually charge, Id say just leave it connected and check it out a few hours later The worst that can happen is that is does not charge at all.
Nope, does not charge while docked. Actually, if I forget to plug it back into the AC adapter, it will lose battery life over an extended amount of time...
Now it does charge through the PC usb with only the tablet, but as previously stated, it is a trickle charge.

The TFP must be completely off to charge from a USB port, and then it will take a long time.
The TFP requires 15v to charge at the normal rate. A USB port puts out maximum of 5v.

ASUS Transformer Pad TF300T power adapter

i have this tablet for a couple days now, when i plug the power adapter to the mains the power adapter gets really hot.
does anyone have the same result or is just normal? i know that the adapter obviously will get hot, but it seems a bit to hot, just the adapter the usb cable is fine and so is the tablet
Its normal. If it gets to hot it shuts off. I hear you have to put it in the freezer to attempt to bring it back.

well, i just dont want to wake up one morning and find the all lot burned.
but it does get really hot
Noticed the same thing with mine. I'm actually on my second pad for other reasons, but I didn't notice the charger getting as hot with my first one. But it only seems to get hot when actively charging. I've checked it after letting it sit still plugged in, but after it finished charging and it was fine.
I just try not to leave it charging if I'm sleeping or going out. Although, I forgot to unplug it this time...

can we charge the tablet via the pc usb port?
its hard not to leave the tablet charging over night when your using every day

No. Other threads in this forum tell you why.
the reason the charger gets so hot is it's 15 volts
and it takes minimum 12 volts for the tablet to kick into charging mode
so to answer your question
a usb port does charge the tablet, but usb is only 5 volts
so it will not show charging
and it will probably take 24 hrs to fully charge
Mine gets hot while charging but once it hits 100% it cools back down. I don't charge it while sleeping for this reason. Also according to the manual the PC will charge it bult as previously mentioned it takes longer. The tablet must be powered off when charging this way or it won't charge.

Same as other itt, it will heat up when charging, but if it's left in the wall unplugged from the tab/dock it cools back down.
Perhaps it needs 12v for full charge speed, but the 300 also trickle charges when plugged into a computer USB port.
i have notice that, when it finishes charging, that just cools down, i was just wondering did i get a faulty one, but as ye say its normal
thanks for all the replys
Luca
even there the charger gets very hot, so it is normal, also, we are going to have very hot temps these days, (40°C here)...
just be sure to not plug it near easy flammable things!
ciao
Yes we have noticed the charger gets very hot might have something to do with fast recharge time the device has

Good evening,
On my charger i notice it is wrting : "output 5v--2A or 15v --1.2A"
This mind that i can use the charger for any phone that charge usualy wiht 5V ?? Do the charger "swap" the voltage by him self if it's not connect to the tablet ???
I don't want to burn my HTC, but to have one charger for the tablet and the phone will be good when travelling
Thanks

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 at 2A 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.

In fact the charger of Asus is quite tricky. I haven't found any substitution, only stock charger can be used.

the connector look to be non standard as if you put an usb extension cable it wont charge.

It's not a non-standard connector -- it's a USB 3.0 connector.
If you use a USB 3.0 extension cable, it will work. If you use a non-USB 3.0 extension cable, the charger won't see that pin 7 is grounded, so you'll just get 5V instead of 15V. There's no bi-directional communication between the two.
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 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.
Hi, my Transformer pad won't charge normally when I connect it to the power adapter direclty - it doesn't show it's charging (though I can tell it is, because after some half an hour it had 2 % more of battery)... can it be that the charger doesn't recognize the tab and gives only 5V? Why? It works normally when I charge it on the docking station (through the power adapter), and the same cable works normally when I use it to transfer media to the pad from the PC...
P.S. When conneted to the power adapter directly, the orange light on the power button of the pad doesn't go on... it only goes on when the pad is on the dock and the power adapter is plugged into it.
Any ideas?

Good info to know, Krhainos. Thanks for sharing that with us. I've been wondering about using the Asus plug for other USB devices I have and the information you supplied answered those questions. :good:
