I used this on my Palm Pre. It charges my Epic 4g, and I tried it out on the Nook Color this AM.
It worked just fine.

There's qutie a number of cigarette lighter adapters available that offer a standard USB port. You'd supply your own cable. Here's an example:
http://cgi.ebay.com/Mini-Car-Cigare...053289?pt=PDA_Accessories&hash=item2a0eed35e9
No, AFAIK, none of these will charge as fast as the standard NC charger. For that, you'd need to go thru the hassle of getting an inverter.
Monoprice has cigarette lighter to female usb chargers for $1.16 that you can use your usb cable with.

well I bought 1 from Wally World and it has a dual USB output abd says it is .5v and 1.5amp but when I plug in my NC it doesnt say charging
does the sprint charger?

Why is that any more of a hassle than getting a car charger?

Yes, the Sprint charger says 'charging' As the others stated, it's not fast, but it works just fine...
it isnt more of a hassle, I have 4 inverters, but they all have fans and make noise I wanted to use a NO noise charger thats all

Larger, heavier, more cords, much more expensive (when compared to a $1 cig-to-usb)...
Just has to be able to push out the current needed. Otherwise it may not charge, or it will charge very slowly.
The Scosche reVIVE II Dual USB Car Charger for iPad has 2.1 and 1.0 amp usb outlets, I use this for plugging in my evo and nc. It definitely charges them both even while having all the wireless radios going and tethering with gps and both screens full bright.

Same issue here, I have a road-trip coming up this summer and I'd love to load up my NC with music and dash-mount it but it'll be a 14-20 hour drive (depending on the number of whiz breaks the wife and kids need) and I don't think I could push the battery quite that long and the inverter when wired to the radio creates quite a buzzing.

Are you using the Nooks specific cable on the 2.1A connection? I too am going on a trip soon, and would love a car charger that can actually CHARGE the nook while using it..
www.amazon.com/Scosche-reVIVE-Dual-Charger-iPad/dp/B003N7NO4Q
Is this the one you have? It looks nice and the price looks okay. Nice find. I also saw a wall plug dual usb version by same company on the same page, do you have any info on that one too? It would be nice to stream line travel chargers to a minimum, thanks.
It definitely charges both. Like I said in my previous post, I usually have both my Evo runniong and the Nook full bright display on for 50 minute commute, using TetherGPS, wifi hotspot, torque and bluetooth, google navigation pulling satellite imagery, and playing mp3s. Granted, it is slower to charge than without all that stuff running but my previous car charger would lose charge with my evo running just gps and no wifi hotspot previously.
I am using stock blackberry usb cables that I ordered from Amazon as well for $1.25 for a pair (google 'B001UC9NOQ', can't post links yet.) These are nice, thick cables that handle the charger great. I leave them plugged in inside the truck at all times. I have not used that Scosche wall charger, I use the stock chargers for travel that remain in my backpack, and I have other usb cables I use to charge at home. I would imagine it works just as well though.

Luckily I'm used to carrying extra USB cables around but the noise my inverter generated while charging was super annoying, went ahead and ordered this to try it out. Hoping it works for what I need, thanks for the tip

Let us know if it works for you. An Amazon reviewer just reported that the Scosche reVIVE II didn't work on their Nook Color:
The nook color needs 1.9 amps, this can't do it. Scosche claims 2.1 amps but it isn't even close. It BARELY charges the nook if the machine is sleeping, when on, the battery charge goes down even while supposedly "charging." Playing video, it's even worse. On top of that if I try to charge a regular phone it puts out too much amperage on the 1 amp side and overheats the phone. Save your money, look elsewhere.
Click to expand...

However, the reviewer may not know what they're talking about. A charger cannot put out "too much amperage." Too much voltage perhaps, but not too much amperage (current). A device draws only the current it needs.
An iPad needs an amperage around 2 A also. I got the Belkin Charge 2.1 made for the ipod/ipad and it DOES charge the nook color. It has a 12V plug with one USB outlet at 2.1A. I used the cable from the nook color obviously...
See, part of my worry is not the current output, but if the nook can actually communicate with these chargers and get a full 1.9A draw, instead of the detault 500mA over non B&N chargers...

I bought the same Belkin iPad charger from Best Buy. Rated at 2.1A. I used it with the B & N USB cable that came with my Nook Color. I used the 'Battery Monitor' software mentioned earlier here or on another post to compare charge current readings against the stock B&N wall charger/cable. The Belkin was charging right at 500 mA (NC was using ~450 mA, software showing +36 mA current). So somewhere the B & N cable & charger must have a unique way of determining that it is a B&N charger / cable and to allow the full 2.1A charge. I used the Belkin 12V charger on my TomTom and it allowed just over 1A charge, so I know the Belkin iPad charger is fine.
Yes, it does charge the Nook Color, if you are at 800 Mhz and minimum brightness running non-intensive applications--and it barely charges at that ~50 mA. It does turn the charge indicator on the B&N cable orange, and the status indicates battery charge on the screen.
I haven't seen a thread that addresses this specifically:
After reading the threads in this section, it seems that the consensus is that the "fast charging" aspect of the NC is based on extra pins in the special NC cable. When connected to any charger with 1.9amps or greater, you will get the fast charge.
My experience is different.
Using the OEM NC cable:
1. Connected to OEM charger, stock ROM - settings say charging, flashes an icon with charging percent on connection and removal
2. Connected to OEM charger, CM7 - settings say Charging (AC).
3. Connected to 2.1 and 2.0 amp chargers, stock - settings say Not Charging.
4. Connected to 2.1 and 2.0 amp chargers, CM7 - settings say Charging (USB)
Using the generic microusb cables (2 or 3 tried):
1. Connected to OEM charger, stock ROM - Can't remember, but not going back to stock!
2. Connected to OEM charger, CM7 - settings say Charging (AC).
3. Connected to 2.1 and 2.0 amp chargers, stock - settings say Not Charging.
4. Connected to 2.1 and 2.0 amp chargers, CM7 - settings say Charging (USB)
This seems to imply that the OEM charger is required to really use the extra pins in the NC OEM cable. Can anyone test and confirm this?
Alan
The nook charger puts out almost 2A of power, where normal usb chargers and ports on computer only put out 500mA. The cable that the nook comes with has some terminations in it that allow the nook to tell when it is connected to the nook charger. It will charge at a much faster rate when using the combination of the charger and cable that came with the nook. Replace either the cable or the charger with anything else and you get low power charging mode which is very slow.
Nook Charger
I keep seeing reports of people getting a fast charge using various other equipment, as long as the chargers are rated >= 1.9A.
Can anyone confirm or deny this? Any testing?
As long as a charger puts out near 2A of current, it should work. The charger itself is just a four pin USB charger. The cable itself... lots of pins in the connector to the NC.

That's what everyone's been saying, but it doesn't work that way in my testing. I have tried 3rd party chargers that output 2.0 and 2.1A, using the OEM cable. None of them are recognized as an AC charger. If we knew how the NC knows when it's connected to the original charger, we could find a way to modify something available at WalMart to quick charge our NC's. There's plenty of Ipad chargers (2.1A) available. The one I have doesn't work, though.
Alan
Update to my previous post:
When I got home from work I tested my ipad charger (2.1A) with the nook color cable and it seemed to act like the nook charger. I did not think any charger but the nc one would work, but it seems it does.
I am jealous. My Ipad charger (OEM) paired with the nook cable shows Charging (USB) under Settings --->About Tablet--->Status. I would love know how to get it to say Charging (AC) .

Keep your eyes open people...as soon as I return to work and have extra cash I plan on ordering and tearing down a charger and cable. Many have noticed poor quality in the chargers..I'm gonna try to engineer an open DIY charger and cable replacement with better filtering components. Hopefully will be creating a thread with full details in 3 weeks...

YAY! I have my soldering station warming up.
Cheers,

yep, this is overdue...plugged in last night...almost burned my hand after an hour of charging. I keep my charger by the bed and the hum is just annoying when I'm feeling a bit restless.
Is there a way to identify problem chargers?
There must be some real inconsistency in the charger build quality. I've never noticed mine gets more than just a tiny bit warm and no humming. I wonder if there was a bad lot of them made? I was trying to look at the charger to see if there is a lot # or such, but can't tell what half the darned thing says. I'm posting a pic of the text on my charger in the hopes we can figure out if there is some way to identify problem chargers.
Edit: My nc came from WalMart.
Well there is a difference in the markings at least...The area circled in red...On mine it is R1101.
Still made in China
Edit: BTW my unit came from Walmart. Not sure if there would be any accounting for things like that.

Sounds great. The simple tests I have done have yielded more quetions then answers.
Looking forward to your data.
ive noticed i cant transfer data on anything other than the nook cable.
The NC cable is special. It wont fit other devices.
described over here....

Charging the NC on a regular microUSB means much longer time.

Yeah, this much is well known...my plan is to find out if there are "brains" in the charger or if it's just a high amp USB adapter. If the latter is true( which I suspect), then it's easy peasy to make a high power port( or just buy a quality one). If it has special circuitry...then I get to try and replicate it( with better parts) and release the plans so others can make DIY replacements.
Edit: I'm willing to bet that the extra pins in the cable are just to increase contact surface...to handle the higher amperage.

That is totally wrong, since other cables WILL transfer data just fine. I use an LG Micro USB cable from my old dare, and am able to ADB push, install, etc just fine.
As it is, the large end of the Nook's USB cable is normal; this means that if the nook is communicating, it is doing so over the standard USB data ports, and not through some special connection. Keep in mind that some of the extra pins from the micro side are for the status light that is built in.
Hmm R1102 here showing 1.9A output
I'm curious.. some people have talked about warranty replacements. What R versions are those?

Hmm....hadn't thought of that...that charger almost has to be dumb...just higher output...the smarts all have to be in the USB/power management chip in the nook. Those extra pins must be for the led and maybe a few for handling the higher amperage. Need to check out the spec sheet for that chip again...
Sent from my NookColor using XDA Premium App
Why does it HAVE to be dumb? I mean, the charger needs to do nothing more than respond to a ping, saying "Hey, im a Nook charger, take me for a 1.9A ride!". I guess that makes it dumb, but no reason said technology won't be in the charger.
Found this external battery with good pricing. Anyone tried this? Does it work with NC?

It certainly should work.
The connections are a little confusing. The male micro-USB coming off the top suggests that you need to connect it to your nook, which would make the whole thing a little unweildy. Also, how is it charged? From a PC? From a AC/USB adapter?
I bought a couple of these:
http://www.dealextreme.com/p/usb-re...emergency-power-with-cell-phones-holder-44749
They're only 2000 mAh, but you can connect them to the nook with the proprietary nook USB cable. Even though they're rated at 1A, my nook recognizes as 2A...
Bonus: built in fold up wall charger.
Not-so-bonus: DealExtreme ships from Hong Kong. Delivery time is measured using the geologic time scale.

I actually have one. It works with my EVO, but not the Nook Color. You can look at the reviews for the item and see others have similiar issues with other micro USB devices. I think I'm going to order a M/F micro usb extension cable from ebay....hopefully it helps this work with my NC.
Micro USB M/F Extension
Johnny,
Are you sure its not charging? The output of the device is 800mA, and the output of the stock charger is 2000mA. So although it may be charging slowly, the nook would not report it as charging. Would you be able to plug it in and leave it for a while and see if the battery% increases?
I'm positive it's not charging. The micro USB seems to be slightly different than "standard" and thus, doesn't fit all the way into the port on the NC. I can try one more time when I get home today, but I don't think it'll go.
I wish this wasn't the case and I've tried it a handful of times when I first bought it. I've only been using it on my phone lately...
Ah ok - if you get the cable and it works let us know It is a good price even with the cable (about $20 total with battery shipping and free shipping for cable), and if that works it would be pretty sweet!

I'll keep you posted. I had been debating whether or not to buy the cable, but for $5 and I can extend the use of my charger, I finally figured it'd be worth it....that and the fact that I want to help people out here so no one buys the charger itself thinking it'll work.

Does it work with your android phone? A lot of after market chargers makes the touch screen unusable while charging. Does it work both while plugged into the wall and using the internal battery?
Interesting topic.
Let me see if I got this straight.
This device has double function?
-If Nc needs charging, U just plug this device and U can have extra power on the move?
-Also, it gets connected to normal wall plug and through this U charge your NOOK?It can work as alternative nook charger (but for sure in slower rate)??
I bought an Energizer XP2000 for about $35 at an OfficeMax (they're widely available). 2000 mAh capacity, weighs about 2oz, comes with its own cord with six different ends for different devices. I plugged it into my fully-charged Nook at 10,000 ft out of Seattle, watched non-stop video at 70% brightness in Airplane Mode for nearly five hours to Baltimore and still had 58% battery left on my Nook (the Energizer was discharged). Other chargers in the line go up to an insane XP1800 that'll power a LAPTOP for six hours!
The sweet spot for me is probably the XP8000. It's max output is 3500mA vs. 500mA for the XP2000, it's the size of two iPod Classics stacked on one another but weighs a little less and it should keep me going for a looong trip. It's $100 so its not an impulse buy (at least for me) but seems like an essential tool for the long distance traveler.

While using this device to charge my nook, my nook is completely usable. It will charge my nook when the device is plugged into the wall.

Thanks for this report. My nook goes crazy when I use the same aftermarket charger that makes my phone unusable while charging. It acts as if someone is hitting the screen randomly very quickly. If you're not having issue with the nook on this charger, I'm confident it won't have issues with my phone either. I will order 1 and find out for sure.

Wonderful report. I'm in the market for an external battery. A couple of questions if I may.
So one of the 6 tips works with an NC? I thought the NC's cord and tip were special to enable the quick charging. Do the Energizer products support this technology?
At dealextreme there is also 3000 battery. Why not using that?

The micro USB tip that comes with the Energizer works fine with the Nook. I don't know about "fast charge" vs. "slow charge" and all that but it definitely works. One SUBSTANTIAL advantage of the XP2000 over the larger capacity models (of the Energizer line) is that you can use any USB-to-mini USB cable, including the one that comes with it, and plug it into either a USB power plug adapter or a USB port on a computer to charge it. The XP4000, XP8000 and XP18000 all require their own power adapter. It's included in the purchase of course but I don't like carrying around another cord. Not a deal-breaker, just a factor.

Well, I said I'd update once I recieved my extension cable, so here it is...
I finally received my extension cable and it allows me to use my Monoprice charger with my Nook, so that's great. In the end, it wasn't needed. I ended up RMA'ing my charger back to Monoprice because the thing had a dull buzz when not being used and a high pitch noise when either charging a device or being charged. I'm happy to report that the new charger works with or without the extension cable on my Nook Color and on my EVO 4G. In the end though, I like the extension cable because it gives me more flexibility when using the charger.

Got it. The slow vs fast charge would be a good thing to know. Can you time a charge with the Energizer unit and one with the stock NC charger? If it can fast charge, the Energizer would make a great addition to the NC.
Thanks either way. The info has been helpful.
I know the Streak 7 requires about 5.4 volts and something well over the normal 500mA to chage so not just any A/C to USB charger will work. Anyone know offhand of a good source for an adapter that will charge the 7 and preferably has a folding plug or the like so it's streamlined and also something that's rugged. I don't want a cheap $1.99 cent no name piece of plastic.
Thanks
Any 5v 2 AMP charger will work.
I too am looking for an a/c charger and would love an affordable recommendation. Ive looked everywhere and I find chargers that are like $24 (way too much) or like a dollar (don't trust it at that price). Thanks alot.

I have one HTC 5V 1A adapter from my old Hero that works (folding plugs), also LG 5V 700ma works as well (from Optimus One). I am sure these are slower at charging but they do work. Would be good for overnight charging.
Any ideas on a good, AA powered USB charger? I know AAs will get eaten pretty quick, but I have some Eneloops sitting around doing nothing and I'd love to get a little more juice on the go.
Juice on the go. Now I have a picture of a white Bronco slowly fleeing the cops down the freeway stuck in my head.
Thanks. I guess as long as they work it doesn't really matter how long they take to charge. Hopefully with all the tablets coming out, a/c to USB 2 amp chargers will become more accessable at lower prices. Until then ill just use a 1 amp charger.

I have one HTC 5V 1A adapter from my old Hero that works (folding plugs), also LG 5V 700ma works as well (from Optimus One). I am sure these are slower at charging but they do work. Would be good for overnight charging.

I got that one, but it only worked for about 20 seconds and then never worked again. I got a replacement, same deal. It seems very cheaply made and heats up very quickly. I made sure my Eneloops had a full charge, too.
I use the newest iphone 4 (white phone) usb plug. The printed spec says 1 amp, but it works fine, I am assuming it is the same unit as the ipad, but a different sticker. iphone 3 plug did not work.

Yeah, i thought it looked shady. But hopefully the cheap 1 amp charger i bought will work. There were some promising rechargeable external batteries on amazon, they run like 60 bucks but they put out an amp and look like they are high quality.
The charger that I bought works great! I'm sure its a little slower charge than the original charger but it is much easier to travel with. Link below replace "DOT" with ". "

I got this 1 for the car. Works great. 5v 2000mA

naw not same as ipad charger that charger is kinda big about 2X2X1 with foldable plugs and also removable plugs to attatch an extension
fyi....1amp is definitely fine. Their car kit includes a 1amp 12v usb charger. Kinda peeved. I was expecting a 2amp one similar to the ac one that comes with the streak. Thankfully I only paid $7 for the car kit which is pretty much what I'd pay for another dock cable.

Is 1Amp enough to charge with the screen on the brightest setting while using gps and wifi ?
Also, I ordered 3 cables from china for $9 total. Ill let you know if they work properly and if so ill link them. Im planning on a cable mod for usb-otg on one of them. Will report back. Also, anyone have a complete pinout on the dock connector? Trying to find out if the only charging pins are the ones used for usb connection. We are going to need to be able to charge while supplying power via usb to devices. Thanks!
I haven't re-downloaded copilot yet since upgrading to DJSteve's 3.2. So I haven't tested everything out yet. Have my hotspot though so I theoretically can. With more 2amp chargers out there, it should be a moot point though. I just picked up a dual one that has both a 1amp and 2amp. With the loaner car at the moment, I'm kinda just dealing with the usb port for charging. Kinda cool it even has usb.
I will say, the viewpad 7x is catching my eye though. And with HC on the Dell, resell should be easy. Just saying.

Yes 1 amp will charge the device at full brightness with GPS, Wifi, and Bluetooth.

Awesome ty. I was using a 2Amp charger but lost it.
Edit.
I picked up an OEM HTC USB wall charger 5v 1Amp.... it does Not charge it with screen on, wifi on, and gps
I assumed it was pad, but I guess it is just an iphone charger. Its a small cube with usb slot. Charges unit with no problems.

I was just wondering if anyone here has spotted a Nexus 7 car charger? Does it not matter if it's not specifically made for the Nexus 7? I'm trying to find one to buy online and I'm having some troubles. First post here I think I came to the right place though. :laugh:

Clicked thanks on accident lol. Any USB car charger should work, but I would make sure you grap a 1 amp one just so it has enough output to charge the tablet at a decent rate.
probably better with a 2amp one. samsung makes one for the tab2, about $12 on amazon, and just use your own microusb cable to connect to it.

Yup, go with a 2Amp one. Most of the cigarette lighter usb chargers are 2.1A.
Avoid the cheap Chinese 2+Amp car chargers, they can be so badly made they cause enough interference to wipe out your FM radio.
/edit 1Amp will be fine but don't go lower, the N7 would likely burn it out.
FYI I tried a 5v 1a wall charger and my gnex7 said f u wouldn't take the charge. 2a or nothing I say

Do you already have the Nexus 7? If so, can you take a look at the charger and see if rated at 1A output and/or try to charge it with a charger that came with your phone?
I am just curious if it can actually charge with less than 2A. The charger listed in the Play Store outputs 2Amps and I thought most tablets require 2A to charge.

Still waiting, should only be a couple of days now though...
I know this is something most people never do...but if you read the manual for the Nexus 7 it says you can charge it on a standard USB port with the Nexus 7 in sleep mode (no doubt because the power draw is much less). Standard USB ports are typically .5A...sometimes less. I would say that's the actual minimum. For the fastest charging 2A is what you want though.
The ASUS charger that comes with the N7 is rated at 2A (10W). I tested an old BlackBerry 0.85A (~4W) micoUSB charger and it seemed to work fine and the N7 didn't complain though I didn't do any scientific tests against the charging rates.
The 0.5A (2.5W) chargers probably won't even charge the unit if you're actively using it.
Cheers,
Kermee

Yeah...read my previous post...the manual says you can charge on a standard usb port (0.5A sometimes less) but only if the Nexus 7 is in sleep mode...ie you're not actively using it. If you can't charge it while connected to USB and it's in the sleep state...then your usb port is probably a low power USB port (<0.5A).
For those looking for a good backup battery charger for it...I recommend this one: http://www.amazon.com/gp/product/B005NGKR54/ref=oh_details_o05_s00_i00
works perfectly with my Nexus 7 (just make sure to use the correct USB out port on it as only one of them is 2A)
DealExtreme Charger
Saw this one on DealExtreme, even come with cable:
http://www.dealextreme.com/p/car-ci...-port-for-google-nexus-7-tablet-146751?item=8
Will be ordering will update when arrives. Also they're carrying Nexus 7 Cables in Pink, Green and Orange.
Was using a Sprint micro-USB plus charger (model PVX8823) with attached cable and standard USB port for 2nd device that I was using for my phone. Output is 0.65Amp which isn't sufficient and will slowly drain the N7 battery while in use. ~$35 at Sprint retail store. Wouldn't recommend for obvious reason.
Fortunately, had a spare Motorola SPN5400A 1Amp I bought with some screen protectors from Amazon because it was cheap like ~$5. 1Amp is sufficiently to maintain the charge while in use at near worse case running 3D games like Dead Trigger, Shadowngun, etc. So, 1Amp is minimum threshold.
You need a charger that:
1) Is capable of 2A (1.5A may be sufficient, 1A is a little too low)
2) Shorts D+ and D- together - This rules out most iPad chargers.
If it says it is made for iPod/iPad it will not work without modifications or adapters.
Samsung tablet chargers will work.
If you take an iPad charger, open it up, and short D+ and D- together, it will work.

Sorry to bump an old thread but any feedback with that charger? I'm looking for one with 2 port to power both my N7 and my droid razr maxx while in car.

Most chargers for android phones will work. I use my HTC charger for ,mine and I bought a car charge that has the standard micro USB connector but also has another USB port so I can charge 2 devices at the same time with 1 charging unit. You droid razor charger will work just fine. You just need to locate a charger that is capable of charging 2 devices at the same time such as this one
http://www.amazon.com/GTMax-Metalic-Vehicle-Charger-Adapter/dp/B005X5L8PI
You'll be good to go with this.

Check out this oem charger from Sprint. Its a dual port charger with a 2a output and you dont have to worry about buying a knock off charger that may or may not perform as expected. It also can be used as a wall charger. Good price too....
http://www.ebay.com/itm/130712043019?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_1459wt_1399
So are any of these confirmed 100% to work? the one a few links back (GTMax) says works with iphone, and I thougth that meant would NOT work with N7. So I am confused on what will work, and I am already on my 2nd Nexus7 being I blew out the USB trying a bunch of differnt chargers for the car.
I would like something that is small and can have multiple USB plugged in, but not a show stopper, just hope to find something on Amazon (Prefer Prime) so I can oder with my case today. Really want to use this in the car more (GPS\GoogleMusic..ect.), but with no power not a great option.
Thanks in Advance,
Drops
