Emergency Charger / Alternative Chargers - Asus Eee Pad Transformer Prime

I am going to a venue next weekend and I'm quite sure my prime will run out of battery, I can't get to a plug socket at the venue but I can charge it in the car however using the charger cable and a lighter socket adaptor it doesn't seem to charge.
How can I charge my tablet when I'm out, is there any solar option or an extra booster battery pack or something.
I am also looking for an alternative charger for when I'm at home because the cable is so small I can't have the tablet charging on my desk where I want it because the cables too short.

Buy a power converter. They are cheap.

Any car charger available now?

Don't know if a universal usb charger will work and if so, we still need the cable. Any thoughts?
you would have to get a USB3 Car Charger which I have no idea if it exists yet
Try a power inverter they aren't terribly expensive on amazon.

HEHEHE This just made me realize that I will get to use the plug in my rear seat for the built in inverter in my Dodge !!! The only reason I can think of wanting a USB3 charger is if I find a mounting solution for the inside of the truck...like the in dash stuff being done with the xoom and ipad.
I'm hoping to combine this:

Most of the 'universal' chargers out there have USB 2.0 connections.
I plugged my TF into my Nook Color charger (USB 2.0, 1.9A output), but the TF didn't react, so I'm expecting it won't charge the device. Might do it while it's powered off, but definitely not while it's on.
This leads me to the conclusion that the device will require a specific car charger. I don't know exactly how they'll get around the 15V source with a 12V car socket, tho.
While it may suck, an inverter with the regular AC charger may be the best solution. Get a QUALITY inverter, tho.

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.

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.

Prime AC adapter

Hi all,
I am about to do a long trip and I do not want to carry multiple AC adapters. I use the Targus Premium Laptop Charger for a few of my devices. I am wondering if Targus has an adapter for the Prime. I will write to them and ask.
What is the power adapter for the Prime? Does anyone use another adapter for the Prime?
http://www.targus.com/us/productdetail.aspx?sku=apm69us
Cheers,
Phil
The Prime uses a proprietary power connector that ends in a USB connector, however it needs 15v to charge properly and I don't think any 3rd parties create a power adapter that will properly charge the device. Even iPad chargers don't deliver enough current to charge the Prime at full speed and adapters made for the iPad are your best bet for finding unofficial accessories for the Prime.
In short, if you are traveling and wanna use the Prime, bring the Prime's power adapter.
Thanks. It's small enough but when you're traveling the less you carry the better.
Cheers,
Phil

If you are willing to buy a 2nd one, Office Depot has TF Prime power adapters that have folding prongs which would make it a little bit smaller.

It should be said that you can choose to use the Asus adaptor to charge other "USB" style devices. When I travel, I take the Asus adaptor because I can use it to charge several devices.

Just an FYI, i bought this one last night at Office Depot and the image on the box shows a folding prong wall adapter. However, the wall adapter inside is exactly the same that came with my Prime. The prongs do not fold down.

Interesting. I purchased 3 of them off the Office Depot website, and all 3 have the folding prongs. I have heard others state that the ones they got didn't have the folding prongs just like the one that comes with the Prime.
I wonder why Asus went to the trouble of making two versions of the same thing, and then selling them in the same packaging...
I'd love to be able to find a small power adapter to carry in my sleeve...

Sorry, but that is very unlikely to happen.
If you don't mind taking 2-3 days to charge your Prime, you could find a small 5v USB outlet adapter that would be more portable, but nothing that will charge the Prime is a usefully short period of time is likely to be much smaller than the stock wall charger.

Well, then sir, I guess I'll half to just update my sleeve!
I don't think it's too off topic but what are the best sleeve solutions for the dock, tablet, and, relevant to this thread, the wall charger?
Sent from my Transformer Prime TF201 using XDA Premium App
I like the Swissgear Lunar 10" net book case for carrying around my Prime while docked. It is very sturdy and has a decent sized pocket that can hold the charger. There are some pics of it in the ultimate accessory guide thread.
However unless you are traveling for an extended period of time, you might not need to carry the charger with you. I get 3 or 4 days of moderate usage out of the Prime, and even on occasions where I am constantly watching movies I haven't gotten less than 6 hours of battery life out of the tablet between charges. 12 or 13 hours if the tablet is in its dock.
Unless you are gonna be away from home for a few days you may not need to bring a charger with you.

[Q] What is the BEST car charger for SGH-I717

Already I have gone through 3 car chargers for my note 2 cheap ones and a Samsung charger none work well charging. The best one was the OEM Samsung but there must be a broken wire in there cause it charges then stops i move the cord and it works again. So I am looking for another car charger that actually charges and wont break in a month. Please post your opinions and links to the charger you refer (with best price of course ).
Here's what I use. About the best for any normal use. Had it since launch and so far so good.

Open up the charger and solder the middle 2 pins together. Or short the data cable.

This really is the best option (but I WOULD NOT SHORT THE CABLE). I downloaded an app that measures incoming amps and tried several car chargers. Most of them only output .5 amps. You are better off buying a car charger for the iPad (2.1 amps) or modding a normal charger as suggested and using any data cable.
I use a modded Power-Bolt charger with a retractable USB cable. This combination takes up the least amount of space and rapid charges my phone even if I'm using Google Navigation at the same time.
The Note comes with a normal USB cable and a shorted wall charger. The Note knows to rapid charge when it senses the short.
Rather than butchering either of my Kensington PowerBolts ......yet I chose to use Current Widget to measure output of basic Samsung microUsb car charger. Depending on battery level it registered over .9A at times yet on 2 hour ride last week w/ Google Maps it wasn't enough. I use ProClip device mounts, but for the hell of it bought Samsung's car mount today to see output of its included charger. Top measurement on 80%+ battery was 1.092A ?????? I'll let battery drain down and report back....

I actually just use a cigararette lighter/USB converter and use a USB/micro USB cable and it charges just fine.

If you do decide to butcher your PowerBolt, you won't be dissappointed. I'm getting over 1 amp now regardless of battery life or Navigation. It's a bit tricky with the PowerBolt Duo, but you cannot tell it's been modded.
You have to peel off the top sticker, then unscrew the top. I did not have a torx driver that was small enough, so I just drilled out the torx screws. Then you remove the top, disassemble the charger, and solder the two inner USB leads on the 1 amp side only. Reassemble the charger, add a drop of glue to attach the top, and put the sticker back on. Now I can charge my iPad3 and my Galaxy Note at the same time, while they're running.
I own both the single 2.1A port and the Duo 3.1A. What are you getting out of 2.1 ports? I don't remember getting over .992A with it. Am I wrong to expect closer to 2.1A?
I didn't look under decal yet, but own mini torx set.
Even though I own ProClip mount I bought Samsung Car Dock on sale at CompUsa to see what charging output the included charger produced and Current Widget measured 1.059A while battery was at 73%. It's the first time I remember getting over 1.0A

After some reading, as long as you get a charger with 15V @1.2A / 5V @2A with a USB 3.0 cable you'll be fine. Otherwise the tablet will have to be off for it to take a trickle in charge.
I bought this one:

Watch out the Output combination voltage and Amperage
What I understand is the original AC adapter is 15v 1.2a (18 watts). So we have to look for car charger output either 15v 1.2a
(http://www.caseen.com/ASUS-Transformer-TF101-Car-Charger-15V-12A_p_198.html) or 9v 2.0A (18 watts) or 12v 1.5A (18 watts).
The NTK car charger output 12v 2.0A (24 watts). That could be why some people report their Transformer got grilled ! But usually the 2A is the max, the TF draw 1.5A only.
I did use the car charger for iPad 5v 2.1A (10 watts) to charge my TF300T (screen off/sleep) successfully but it took longer time. Almost double time of the AC adapter.
