[Q] Gary Key - Car Charger Question - Asus Eee Pad Transformer Prime

Hi Gary,
I would like to have a car charger for the Prime. I've seen a couple 3rd party ones that may work....However, I DO NOT WANT TO BURN UP MY PRIME.
I was wondering if ASUS had a recommendation of a reliable one, or maybe even had one in the early stages of development.
Thanks,
Bob

While you wait for an answer I charge my tablet on the go with one of these
http://www.amazon.com/PowerDrive-RP..._3?s=automotive&ie=UTF8&qid=1333830174&sr=1-3
It's a different one but same functionality. I always have it in my truck and has totally replaced the need for me to have any dedicated mobile chargers. Worked fine for my prime on a recent road trip.

Thanks....I already have an inverter, which I will use if necessary, but with a passenger in the car, the front seat area gets a little crowded....geez.....maybe I ought to put her in the back seat.
Since the car runs off of a 12v battery, it should be relatively easy for ASUS to produce a charger designed for the Prime.

Might not be too bad an idea
Though yes I agree. It would be easy enough for them to make one just has to be financially sound.

Can be totally wrong now.
Prime Needs 11+ volt to charge in normal speed.
A Phone or the standard chargers with a usb port that you can find anywhere usually output 5V.
People swap charger back and forth between their phones or other devices that have USB connection on the charger.
If Asus release a charger for Prime that Output 11+ volt I don't think it would be to good if people plugged there phones that only need 5V.
And I pretty sure that people will try to use it and don't look at the specifications of the charger and the specifications of their device. They will just plugg it in expect it to work. And after their phone broke they will blame Asus for release a charger that don't work with other devices.
And if Asus release a charger that don't have a removable cable and that only fits Prime. Folks will be made about that to.
Just some late night thoughts.

Correct...It would have to be a dedicated cable to cigarette lighter .....not a removeable cable.

Shouldn't be a problem, the prime charger and usb cable are designed so that it wont cause issues with other devices. If you look carefully at the charger and/or usb cable you can see 9 contacts rather than 4. If you plug a standard usb cable in to the prime charger it will only make a connection with the 4 contacts not all 9.
Car adaptor can be made the same way so it will provide 5 volts on a standard cable using the 4 contacts and 11 volts when all 9 contacts are in use.

I use one i bought from radio shack, with changeable tips (outputs 12v/1a), in combination with an usb tip (extra attachment bought separately) , altogether about $20.
I plug the prime's usb charging cable straight into the usb attachment, and it's been working just fine.
Nobody else uses that charger but me, and it stays in my car, so i m not concerned about other people's phones getting burned out XD.

Any 3rd party chargers and cables?

Does anyone have a 3rd party charger and/or cable that will work with the TF?
I am also interested in finding that question out. I move around alot, and would like to have an extra charging cable.
Would the cable for the iphone/ipad work?

No Apple cable will work on this device. The Transformer has a proprietary charger interface, so the cable would have to be made specifically for this device.
Similarly, all Apple product chargers use their own proprietary interfaces, so chargers made for iPhones or iPads will only be made to work with iPhones or iPads, not other devices.
And the funny part is that someone responded...

Haha, no iPhone cable would not work with Asus. Last I checked, Asus cable was proprietary as well.
Wait a little, soon someone's gonna dismantle one and they will be anywhere (monoprice, ebay)... (i guess(hope), the apple cable actually is everywhere even if it is proprietary...)

cable no, but the ipad charger itself is 5v 2A. Has anyone tried one, if it works may provide an easy solution for car charger.
I would love an additional cable. I'm going on a trip and I could just see me losing the one and only way to charge the Transformer. Stupid proprietary cables. I still love my Asus Transformer, but we need uniformity.

It is a different size entirely. If you would like me to post a picture I suppose I could, but unless you're going to take a crow bar to your TF to wedge it in and hope the pins magically match, you're SOL. Sorry.
I think he meant the wall charger (the one you plug the usb ipod cable in...)

I believe they're just referring to the charger itself not the apple sync cable. And no that isn't likely to work as the ASUS charger gives out 15V/1.2A on one of the pins unique to USB3
The 6ft USB 3 Male/Female extension cable is now back in stock on monoprice. For those that haven't been reading up, this is essentially an extension to charge your Transformer since the extra pins in USB 3 are used for power.

Any car charger in the market? Off topic but optimumwifi is getting 6mbps down, 10mbps up on this baby.
Bumping this thread. I find it hard to believe (or at least surprising) that this has been out 3 months now and I still can't find any third party replacement cables and/or 15v chargers. Paying $25 for a factory one is simply not something I can do, it just makes me sick to my stomach.
The most important thing I would like to find is the cable. I did buy a monoprice USB extension cable, which at least makes using the device while charging possible - but it is no solution in the case of this factory cable breaking in any way. I always like to have an extra charging cable on hand, and usually pay $1.99 or less for such things for my other phones and tablets.
need cables
@brunes
I agree with you. This reminds me too much of the original asus eee pc. There were no additional chargers nor expansion ssd (mini pcie) available for months. People were coming up with all sorts of work around ideas. Argh.
The idea of not having a replacement cable and charger does make me very uncomfortable. This is really unacceptable, and I hope Asus fixes it immediately.
I have to think about a post I read: just buy a second one and immediately return it with the bad charger if yours goes bad. This seems to screw the retailer, but hopefully Asus covers their cost in these cases.
In any case, it is a bad problem. I wrote my newegg review to exactly highlight this problem.
Not having a replacement cable is not a very comfortable feeling.
Anyway, an iPad charger does work for the tablet. I don't have a dock so no way to test it.
However, I noticed that using an iPad charger, theTF does not chnage the battery icon to charging and it charges a bit slower.

It is charging at 5V. I assume using diodes to charge the cells in parallel instead of series without causing a short. Only other explanation is ASUS put DC-DC regulator in to ramp up the 5V. Only works while off or asleep and is sloooooowww...took me 8 hrs to get 22% charge on 5V USB.
a rabbit just chewed up my new transformer's cable
i emailed asus, but from my googling it looks like i'll have to spend about $40 ordering a replacement cable from a random retailer. sucks!
Check the DIY charger thread link in my signature. With 2 off the shelf parts you can have another charger for under $15.

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
looks like the ac adapter is available online...

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 was just looking at this;

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.

Can you charge the Gtab through USB?

Just ordered a portable USB charger.
Does the gtab take a charge from either of its usb ports?
I hope it does
Nope, but I am a noob. Ask an expert.
If it does, it would have to be from the mini USB port. The full sized one is a master (i.e. it supplies power to devices and operates them through the tablet), and the mini one is a slave (i.e. it lets you access the device as mass storage through another).
Other than that I'm not sure. I'd be interested to know this as well.

It does not.
I don't think that most USB ports provide enough juice to charge a battery like the G-Tab's, so they probably just didn't bother making it a possibility. My friend's iPad requires a wall wart, too.
Oh poo.
The charger I boughts a 16000mah
It can charge the ipad etc... Bought it mainly for my phone but was hoping it would charge my gtab as well.

It will absolutely not charge through either of those ports because it was not wired that way. DO NOT TRY FORCING THIS or you will in all likelihood destroy your tab.
Hopefully a basic cable that attaches to the dock port will allow charging via usb, even if it's a slow trickle charge.
Someone here said that the SanDisk Sansa cable fits in our dock port, but I can't recall if it worked at charging or not, though I'm sure if it did we'd be all over it.
USB voltage < gTab voltage
Per the Viewsonic web site the gTab operates at 7.4V and comes with a 12V charger. USB charges at up to 5V iirc. Maybe the gTablet is set up to charge one cell of the battery at a time, but I really wouldn't count on it. Likely the battery charging system isn't even connected to the USB ports at all (but I've been wrong before).
I say you give it a shot. In addition, I will offer you $25 for it, plus shipping, after you are done. I want to try removing the anti-glare layer as an experiment.

[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.

Now that's weird !
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?

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!

Making a charger for Prime

Hi,
If you lost your charger for the prime would this work to charge the prime too or the keyboard dock ?

If you lost your charger, you would be better off buying a new one from a place like Office Depot (http://www.officedepot.com/a/products/768723/ASUS-Power-Adapter-For-Eee-Pad/). It would be safer and it would probably be better for your the longevity of your Prime.
Something like the charger shown in the video might work OK for the Prime. I say "might" because the Prime expects 15v not 12v and generally won't enter "charging mode" from only 12v. However it will still charge the tablet, just more slowly than the original Asus charger.
I build a charger for my car from a similar setup to what is in the video. I followed the directions that are in the ultimate accessory guide post. My charger switches to 15V so it charges at the normal rate. Mine also has a USB port so I can charge my phone at the same time.
i got my second charger from ebay. cost me $15, its was a new in box asus transformer wall charger. Now i have two and dont worry about it.

I dont think its the prime thats entering "charging mode" but rather the charger itself that gets thrown into "Charge Mode". There is a connection at the 40 pin connector that goes from ground back to the charger, i do believe THAT is what makes the charger output 15v instead of 5v so it doesnt fry your other USB devices.
There are many people who have used home made chargers for their prime. Look for a thread talking about the pinout of the 40pin connector and you can find more. Hope this helps.
