The official B&N car adapter is $25 in the store. I am thinking it might be better to just get a car inverter for a little more money and use the regular wall plug that comes with the device, leaving you open to using other devices in the car too.
Thoughts?
Try this on amazon.com. This Kensington charger has a high output (2.1amp) and a low output. You need to use the Nook usb cable to charge though.

I was thinking something more like this:
http://www.amazon.com/BESTEK-invert..._1_1?s=wireless&ie=UTF8&qid=1322763865&sr=1-1
And using the regular wall adapter for the nook to charge it in the car.
http://www.amazon.com/AmazonBasics-...1?s=electronics&ie=UTF8&qid=1322765700&sr=1-1
7 dollars 2.1 amp should work and save you a couple bucks. I believe you can only use one port while charging the nook because of the split in power.

My only concern is, other users have said it doesn't charge quickly via powered USB, so if you had the inverter with a regular outlet plug, you could charge the nook much faster in a car with it. I guess it depends on what you look to do.
I do like the price on the one you linked though, so much better than B&N one.

With a standard USB port on your PC (most are 0.5 amps), you would be absolutely correct - charging would take forever and only with the screen off. This, however, provides up to 2.1 amps - enough to charge an iPad and, presumably, a Nook Tablet quite comfortably. I would assume, however, you would need to use the included cable instead of a standard micro USB - from what I've been reading the cable has additional pins for these power requirements.

Yes, I read that the USB cable is not a standard one. So I guess I'm back to: Would the utility of getting an inverter (for about $15) be more useful than to get the <$10 USB charger. Either way, the B&N USB charger is a complete rip off at $25.
But then again, they want $20 for 2 screen protectors...

I guess it would depend on what you can dream up. I personally only have USB-based devices that I use in my car, hence my USB adapters. I've never felt the need for a power inverter.
If, however, you have several devices that have custom charging dongles (or plan on getting any) the inverter would be a better investment as you wouldn't have to get a separate car charger for each of those devices. Not to mention, you could power a laptop for a passenger, charge your kid's Nintendo DS, etc.
It really just depends on what you have. Sorry, I'm not being helpful with respect to a decision.
A Highpowered (2amp+) USB adapter would be more efficient than a power inverter, and take up less space. Converting 12v DC to 110v AC then back down to 5v DC is a waste of energy, and in the long term it'll put a damper on your car battery. I'd never use an inverter for more than a few minutes without the car running either. I personally use both for my charging on the go needs, especially since laptops need a bit more than 12v to charge.
Look for a USB adapter than can charge an ipad (2.1A).
I believe the Nook Tablet needs 5v 1.9A (or 1900mA), more is fine (totally safe.)

Based on what you said, I didn't realize until now that the 2.1amp USB adapter would charge it at the same speed as the inverter.

Yup, I took a quick glance at the wall-plug for the nook, and it is indeed 5v 1.9A out. So a 2.1A USB adapter is more than enough to charge a Nook at full rate.
I bought an inverter, but I use it for my laptop, too.
Cheap inverters do not have a clean sine wave and can damage electronics. You should get an inverter with a pure sine wave to be safe.
12v charger for book hd
Normal USB car chargers do not work with the nook HD. I bought a 150watt 12/240v inverter that plugs into a lighter socket. I plug the nook mains charger into the inverter and it charges the Nook no problem.
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.

By chance do you have a link to the EverReady battery pack? I would like to see it

I have an XP8000 from Energizer, and work perfectly.
w w w.energizerpowerpacks.com/us/products/xp8000/
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
steve
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.

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

I own an iSound Portable Power Max charger http://www.amazon.com/i-Sound-Portable-Power-iPhone-BlackBerry/dp/B00439G3WS and just realized that it does NOT work with the Prime. Anyone know of any similar products that do work?
Edit: I found something that will charge the Prime, however, it's neither inexpensive nor small.
http://www.sejats.com/12000-mAh-Solar-Battery-Charger-for-ASUS-Transformer-Tablet-ZERO-1-ASTRFORM.htm
Well that sucks! I just bought a Motorola P893 to have back up for my Razr and was hoping to be able to use it for my Prime as well (when I get it)... Does your charger not come with the appropriate connectors? Mine probably won't work either, and its only like 8,000 mAh anyways, probably not enough for a tablet???
Anything that can plug into a USB port works with it. I've tried it with 4 different phones and an iPad 2. They all work except for the Prime.
I have a few newtrent devices but they won't do anything but a trickle charge when the prime is shutoff, if on it draws more than the newtrent imps can provide (5V).
I don't know of any off the top of my head, but the input the prime is looking for is 15V 1.2Amps, find a battery pack that can provide that and my guess is that it should charge the prime.
Prime needs a USB3 charger, it seems. Who knows if they exist...

Here's a review of one that should work:
http://www.androidpolice.com/2012/0...c-of-portable-chargers-with-a-price-to-match/
Realistically, anything that was designed to charge a cell phone or iPod-sized device won't work well for the TF Prime as it will take too long to recharge your tablet to be really useful.
Also, the Prime's battery is significantly larger than most mobile backup batteries so you won't be able to get a full charge. At best you will be able to recharge your battery to around 25%, but in most cases you will probably get a lot less.

I'm under the impression that the TF Prime looks for a higher voltage -- 15V to start charging, not just a higher current at 5V.

The solar charger I posted has a button for 5V, 9V, 12V, or 16V settings. It will charge the Prime at 12V and 16V.

That depends greatly on your definition of "work."
You can charge the iPad via an iPhone adapter or an external battery designed for use with a phone however the iPad will charge much more slowly. Also, since the size of the iPad's battery exceeds the size of most external batteries they usually won't fully charge an iPad.
By the same token, you can charge the TF Prime via an iPhone adapter or similarly powered external battery. But it will be very slow, almost to the point of uselessness (~2-3% an hour, if you are lucky)
In both cases for most non-standard chargers you will need to have the device turned off for it to charge at all.
That's interesting a solar charger, how long does it take to reach capacity though?
You need 15v to charge normal speed.

This is true, but frankly it looks way too shady for me to be attaching to my TFPrime. I prefer to wait for more commercial products, versus quick Chinese ones.

Good point.
For $125 you would probably be better off spending $25 more and getting the keyboard dock. It contains a ~6 hour extended battery plus a full keyboard, USB port & SD card slot. It also exactly matches the TF Prime, acts as a screen protector and tablet stand and doesn't add a lot of bulk so it will fit inside most cases/sleeves that can also hold the tablet alone.

The dock works great and I kill the battery in my dock by the end of the day but my tablet battery is still above 80% when i get home if I play games or surf all evening on it it is still not below 25% by the time I am ready to charge it while I sleep. If you kill both batteries in one day then you probably haven't done much of anything else but stare at your tablet.
I second the dock, sometimes I go a few days without charging because the dock so generously gives up it's own life first
I third the dock! Very useful but it can get a little heavy. I was hoping to get an external battery for under $50. Does mAH matter, I seem some big ones with 6600 maH wondering if that would work.
i've looked around and they go for around 20 bucks...
overpriced as hell... where can i buy this cable cheap? thinking of buying couple.
Since the connector is proprietary and not a lot of 3rd parties have started making them they can be hard to find. You will have better results if you look for a cable fro the original TF101 Transformer as the cables are the same.
Here is one on eBay for about $13
You should note, that if you are hoping to charge your tablet you will be much better off buying an Asus wall charger since using the cable to charge by USB will take a very long time and won't work while you are using the tablet. Similarly iPhone chargers and similar USB wall adapters will also be very slow and won't work while you are using the tablet.
You can buy additional wall chargers from Office Depot. I have purchased several and they have very fast shipping.

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.
