Making a charger for Prime - Asus Eee Pad Transformer Prime

Hi,
If you lost your charger for the prime would this work to charge the prime too or the keyboard dock ?
http://www.youtube.com/watch?v=UaG__WOWEHI

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.

12V car charger!

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?
$1.99
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.

Unfortunately, worthless.
Transformer needs 11v-15v to charge reasonably well. Any 5v charger, even at 1000000 amps, will not charge the TF with screen lit, or charge takes days with TF turned off.
Much harder to find auto chargers in the 11v-15v range, some that say 12v are actually not. I found one advertised as 12v (that measures 9.8v actually) and it also did not charge TF. Good luck.
Wont work. Unlike most devices the Transformer does not use 5v to charge like the iPhone and many other Android devices. It does use USB but it will only charge via Asus's special chargers. This is because our Transformers charge via 15volt and the charger cable is actually a USB 3.0 cable that has extra pins in back, and the 15volt pin is one of these extra pins the USB 3.0 layout provides.
Edit Bob Smith42 beat me to it by a few seconds lol
Be aware that it's incorrect to say that the TF won't charge from a standard USB charger. It does charge however it only trickle charges and therefore takes much longer. So let's make sure we are clear when we respond about what works and what doesn't. I used my iPad 2 amp charger on the TF and went from about 30% charge to about 85% charge in about 6 hours (screen off). The absolute fastest way to trickle charge from a generic adapter is with the TF powered off. Hopefully Asus will come out their own car adapter for the TF.
The charger that the original poster mentioned WILL trickle charge the TF. Also new TF users should know that the TF will not give any charging indications when plugged into anything other than the Asus charger - but it is trickle charging none-the-less.

One thing to mention that you can do if you have the tock is trickl-echarge THAT while still using the pad... then in 5-6 hours when the padd is getting low, you can dock it, and it will charge off of the dock while you keep using it. Once fully charged, undock it again, etc. This is what I want to do, and why I want a second USB cable.

portable battery pack.

Has anyone found a portable Battery pack that we can use on the TF? I have several that I have used for my iPhone and my old iPad2 but all are only 5v. is there one out there that can charge out TF or is the keyboard dock the only way to go for extra Battery?
There are several battery packs used for notebook computers that will work listed on Amazon. Just be sure they have a 12Volt output. EverReady had as battery pack that will also work but you will need an adapter provided by them. The key is that you need an output of 12 to 15 volts to charge the TF or Keyboard. You might read Devcake's post on a DIY charger for the TF as information on the voltages required to charge the TF. There is also a post on external batteries that might help.

You will need a conector for Asus (Willy cable WI15) from them. You will have two free tips a year for the life of product
By any chance do you know the tip number?
The cable you note doesn't appear to connect directly to the Transformer.
What setup are you using to connect to the Transformer?
Thanks

The cable it's a Female USB with 16V output. You need the Asus cable.

Or get both, even better
I just saw this while I'm looking for a battery pack.
On a german page I found this interesting:
w w w.intecro.de/XTPower-MP-16000-Powerbank-mobiler-Akku-mit-16000mAh-fuer-Laptop-Handy-iPhone-iPod-iPad-PDA-MP3-Player-mit-20-Adaptern
(can'f find an english page for this product)
Could I use this one by using an adapter?
I just got an Anker Astro3 10000mAh battery pack. I plan to use it while camping this summer, mainly to charge a phone, but occasionally to charge my tablet.
It is intended to charge 5V USB devices, and has two USB ports. It also has a 12 volt port. The adapters for the 12 volt port, of course, do not work with USB or the Transformer. So I made an adapter, and I am good to go now for charging the tablet.
The battery pack charges from a 12 volt wall charger. I have also made an adapter to charge it from the 12 volts on my motorcycle. So I will be charging it from the motorcycle during the day when riding, then using it to charge my devices in the evening at the camp. I've already tried it a couple of times, and it worked well.
I tried to charge the battery pack using a solar panel, but the solar panel was far too wimpy. It was like trying to run a house air conditioner from a penlight battery. It may make you feel good to try it, but it isn't going to do much.
So far so good. This is very close to what I need.
The issues I have had to work around are:
1) I want to also charge an in helmet bluetooth intercom from the USB port. But the charge current is so low, the battery pack auto powers off, thinking nothing is plugged in. Not a big deal because I can plug in my phone at the same time. That keeps it turned on until everything is charged, then it auto shuts down.
2) When I charge the Asus Tablet, it doesn't appear to auto shut down. Just the opposite of #1, it looks like the load stays high enough to never shut down when charging the tablet. This may not really be true, as I have only tried it a couple of times. Also, it isn't good for much more then one and a half charges of the tablet, as expected.
3) You need to figure out your own harness to get the 12 volts to the tablet.
4) No charge cable for a car. I mean this is rated for an input of like 10 to 15 volts, or some such. This thing is GREAT for charging portable devices. Charging it from a car is as simple as a cable, but there isn't one.
Over all this charger is a winner. At right around $55 US, I recommend it, if you can fabricate a plug for charging the Transformer.
Try a 12V UPS type battery along with a 2A fuse and adapters. It only costs about $20 or so. Plan on using only 50% of its capacity and recharge often to get the most life out of it.
Someone posted this product on another post

For me, this is actually what I use now. But it has issues.
One is simply that it is large. I carry it in the trailer that I tow behind the motorcycle, so it is OK, but a bit too large and heavy. It is a gel cell that has about a 48 WattHr capacity. LiIon has a a lot less and weight. In this case, it has about the same capacity, in a very small light weight package.
The other problem is charging the lead acid battery is an issue. I need to carry a AC charger and find AC when camping. I put a diode/resistor combo in the trailer and tapped off of the taillights. but by the time the weak motorcycle voltage gets to the taillights, add in the diode and other losses, and I'm lucky to see 13 volts at the battery. Not enough to charge it very well. The LiIon pack I use has the supply built in to charge properly from +12.
So I've tossed the lead brick battery (literally) and upgraded to a portable LiIon pack. So far so good.
This is what I use "Portable 12V DC USB 5V Rechargeable Lithium Li-ion Battery Pack for CCTV Camera" search on ebay, you can get one up to 13AH
I got a 3.8AH version for $16 , Dimension: 9.2cm X 6.0cm X 3.0cm
Outout rated 5V (5.8AH) and 12.8V (3.8AH)
small modification because the charger is NON-US wall plug, I just pull the plug pin out and add in a regular power cord cut off from an old appliance
Keep the USB plug for 5V use, cut the 12V DC cable and connect it to a female USB cable (pin 1 and pin 4) , then you can plug in the Asus usb/charge cable directly and charge or power the Asus

[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?

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!

[Q] Gary Key - Car Charger Question

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

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.
Sent from my Transformer Prime TF201 using XDA Premium HD app
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.
