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:

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.

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.

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.

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).

You'll need to purchase from B&N (unless somebody else can find another source). It is unique. If you look at it, the connector not only has 12 pins, but is longer. The extra length is what initiates contact for charging.
Although its slower to charge attached to the PC (500mA instead of 2A), it does charge. I left mine overnight and it was fully charged using a standard micro-usb cable.
My Samsung Galaxy Tab is like this. There is a software work around that makes it charge faster over USB (see http://forum.xda-developers.com/showthread.php?t=1323957). This gives hope that someday we get similar functionality.

I have heard it will only charge on PC via USB if the screen is off. Otherwise, it uses too much power to really charge it.
What would happen if I put the USB port into a power adapter? I use them to charge my phones when I don't have access to my laptop's USB ports.

using the nook cord here with my htc phone charger. all works well
None of my generic USB cords work.
USB Extension cables appear to work with charger
I tried a USB extension cable with the Nook charger and it does work. That means, I think, that the A end of the USB is standard.
I know nobody wants to sacrifice the Nook cable but I'm surprised no one has done this yet. I thought at least the Nook Color cable would be cross-compatible with the NT and someone would have buzzed out the Color cable by now.
There's the bi-color charge LED, but I can't see how they could put a charge chip in there; no room.
This cable is unique....and poorly constructed/misaligned to the 2 prong AC adapter. The USB does not fully insert into the AC Adapter. If not perfectly placed/propped while plugged in to charge, the NT does not charge or charges slowly.
My remedy has been to move the NT closer to the plug so that there is little to no bend in the cable leading to NT.
Will B&N send another if I request online/call? Or, must I unroot and go to a B&N?

Yeah, it's terrible. I don't have any charging issues, but the misalignment causes a ton of electricity to leak, so don't leave it on a couch or a fuzzy blanket unless you want (shockingly) pleasant surprises for hours. I wish they would make an all-in-one-piece as well (do they? would be a good add-on). Sheesh, poor design.
With the billions and billions of 3rd party cords out there, it seems amazing that none exist for the nook tablet. I don't really wanna pay 30 bucks for a backup charger.
2mA too much?
I noticed that the official Nook charger output is rated at 1.9mA - I've just bought a generic 2.0mA USB plug adapter and am hoping that it will work with the existing Nook USB cable. I'm hoping the extra 100mA won't fry the thing...
The extra pins in the Micro end of the Nook USB cable are used to support the higher power draw of the Nook when charging at full rate (2.0A) since the max rated current of a Micro-USB connector is only 1.8A. I am sure they also use the additional pins to make the cable proprietary and possibly also control the bi-color LED. The extra pins are set further into the connector so that they do not cause compatibility problems with standard Micro-USB cables.
In addition to this, the charger brick that comes with the Nook has its Data lines shorted, to each other I believe, to indicate to the Nook that it is plugged into an adapter and not a computer.
The combination of those two things is what is needed for the Nook to charge at its full charge rate. Since the USB A end of the cable is a standard 4-pin design, extension cables that offer all 4 pins/wires will work fine.
The Apple adapter (even the 2.0A version) will not work because it uses a voltage divider (couple of resistors) on the data lines to indicate to the iPod/iPhone what style charger it is (1.0A or 2.0A). One of the data lines is held at 2.1V and the other at 2.7V. Depending on which one (D+ or D-) is at what voltage determines what style charger it is. So the Nook does not recognize the "non-zero" voltage values on the data lines and assumes it is a PC, so it will only charge at 500mA.
Other vendors power bricks use the same "short the data lines" trick as the Nook adapter so several others will work. I believe as mentioned already in this post that HTC uses this same method.
WARNING
Be careful though because if the adapter is rated at less than 2.0A (e.g. 1.0A) you could cause damage or fire. I am not sure if the Nook will slow down charging if it detects the charge voltage dropping if it is trying to pull too much power out of an underrated supply.
If you really want to use your Apple IPad adapter with your Nook Color/Tablet cable you could modify a USB A/A extension cable to disconnect the Data lines and then tie together only the data lines on the side of the cable that will go to the Nook. Again, this can be dangerous, I can not take any responsibility if you attempt to do this.

AdamOutler has confirmed that it will charge on any usb cable, but the tab must be off and it will not show signs of charging. I'm pretty sure that this was charging from the computer.
My device battery is way low.. I'm charging on normal USB so it's trickling up at a rate of about 0x0010 per 2 minutes. At this rate, the device will be ready to use in aproximately 1.5 hours... And until then i'm sure nothing will show on the screen.
This may or may not apply to using the Barnes and Nobel cable. I do not have one available though.
So, if you ever come across a situation where the device won't turn on even after being plugged in, leave it plugged in for a few hours. It could have a case of the "sleeping death".
Also, I'm able to verify that the device... even when totally powered off will charge on a standard USB cable.

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.

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

You will be charged at much slower rate (limited to 500ma max), or not at all if your phone battery is almost dead. iPhone chargers are designed for iPhone only. You will need a Samsung auto charger (some other non-iPhone smartphone chargers may work too, just not iPhone chargers).

It will definitely work. The question with those cheap ones is, how long will it last. I usually try to find an OEM branded one like this:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250973439590#ht_2859wt_1000
Typically, chargers with USB port on it will only do slow charge. In order to support fast charge, you will need short out the data pins to allow phone to draw more than 500ma. Typically auto-chargers that comes with microUSB plug directly, such as the Samsung auto charger, will do so, asume your charger is rated to output more than 500ma.

It will be able to charge it. Keep in mind IF your iPhone USB charger max current output (5V 1000mA) is LESS than the Note's charger output, it will take longer to fully charge - but it will charge and will NOT damage the phone.
If you're looking to buy a new usb charger, look for one with the highest mA output rating since whatever device you plug into it will only draw what it needs. ie, my iPad charger is rated @ 2A/2000mA so it covers every device I own (all rated for different current inputs from 500mA up to 2000mA) and that's the only usb charger I take when I travel since I just have to switch out cables to charge other devices. On the other hand, if I only had a lower current rating usb charger, my iPad (requires 2000mA) would be out of luck.
Current output info can be found on the respective charger of your favorite device.
Hope that helps.

poop i couldn't cancel my amazon order. well i 'm sure i'll still use it.
When ever I drive, I have my phone hooked up to my Escort Red Line radar detector and my car's stereo via bluetooth (both). In order for me to use the radar detector effective, I need to have GPS and Blueooth enabled. This is a HUGE SUPER OMG battery drainer for my amaze. 20 minutes drive kills about 35% of the phone's power. My radar detector offers a slot to charge my phone BUT it still drains, not enough juice flowing in. Someone said it is because it's probably a .5amp.
So I am running a extension from the 12v lighter that's in the trunk to the front of my car. Amazon has a generic 2.1amp for 3 bucks.

But on ebay, I found the original HTC car charger for 15 bucks which is a 1amp.

What do you guys recommend? My logic says go for the 2.1amp, the phone will draw as much as it needs from it.
The 1amp.
Anything higher you'll damage the phone or the battery.
A wall plug power supply or a usb supply is 5.0v/1amp.
The 2.1 amp is probably 1 amp per port. Although it does not seem to specify.

That means a higher capacity battery (more current NOT MORE VOLTAGE) will damage the phone?!!!!
Totally wrong!
A higher current will not damage the phone. A higher voltage will do it!
Please do not mix the current with voltage!
Voltage is same 5 Volts (±5%) for these “USB like” applications (1A or 2.1A power supply our case )They use USB socket/connector but usually only pin 1 and 4 (+ and-)
Regular computer USB port can supply max 0.5-0.9 A depending on version.
For battery charging devices the current can go to 5A.
Higher voltage will trip a warning window telling you to disconnect and use official HTC equipment.
The phone monitors input voltage to protect the equipment.

and to add to that... unless you take the charger apart and short pins 2 and 3, it will only ever draw 500mA, as it assumes that it is hooked up to a regular powered USB port... I have bought multiple car charger usb adapters, and I have taken all of them apart and soldered the 2nd and 3rd pins together... otherwise charge time = forever, and sometimes it won't even charge if you have wifi or data/gps/bluetooth all going at once...
I recently got an Amaze and am generally happy with it. The biggest problem I have right now is finding the right car charger for it because the car charger I previously used (a 1A monoprice car charger) doesn't give it enough charge. I have been reading through the forums and some has been saying that if the charger is not working properly, it will recognize it as charging via USB rather than AC. In my case, the phone seems to be reading it as charging through AC, but there still doesn't seem to be enough current going through it. The phone will only charge if NOTHING is going on (i.e. screen's off, no GPS, etc.). I've been using CoPilot GPS and it draws the battery like crazy. Anyone has any idea as to which car charger would work properly with the Amaze such that I'll be able to charge (or at least maintain the charge) while using it as a GPS? Do I need to go up to a 2.1A charger?
I would look for a 4-5 star rated 2.1a car charger on Amazon.
Just read through the comments and feedback and you'll find one that's right for you.
I prefer the USB charger base itself and then using the OEM cable that came with the Amaze.
It seems to charge faster with that cable, at least to me anyway.
Remember though if it's rated 2.1a but has two USB slots that 2.1a will be cut in half if used to charge two different devices.
Hope this helps.
I couldve sworn we talked about this months ago. Let me see if I can find the thread.

you won't get the full 2.1a unless you usee a charge only cable or modify the charger as I stated above...
I ended up getting a 2.1A car charger and a USB charge only cable, and it's working perfectly. When I have the screen on full brightness and doing navigation with Co-Pilot GPS, my phone's no longer losing charge and is actually charging. The combo also works with my tablet as well.

This is damn helpful! So THAT is why when driving and using gps or whatnot I would always lose more battery even on charger.. So basically I can just solder the middle 2 pins together to trick it into thinking it is being powered like a home charger? No chance it will hurt anything I assume?

I have done this to every single one of my USB car chargers... not a single issue...
