At dealextreme there is also 3000 battery. Why not using that?
The bigger the better right?

Each of these options has pluses and minuses. The reviews at each of the links say as much. One of the batteries you linked to has retractable power "prongs" so the A/C adapter is built in, a great option. Another has a proprietary power cord and the third has no charge status indicators (minuses, IMO). All of them are a little heavier than others I've seen, but only by an ounce or so. They are certainly cheaper than brand name alternatives. I won't be the first to plug no-name power sources into my electronics but I appreciate the feedback from users who do.
i go on long trips that I might not have a wall plug in (bicycle touring). I have two of these bad boys:

they power the nook color and all of my phones no problem. each battery has 2 usb ports to charge and one cable to charge my laptop. It's a lot of money, but I can charge my nook color 5 times over with one of these.
Pricey but thanks for the link.
Do they "fast charge" your NC like the stock charger does?
And the 3000?Why u didnt check this option?Two more options just became available:

I JUST ordered the 2400mah this week... But some consolation, by a pure mah/dollar point of view, the 2400mah is the best:
2400mah 193.55mah/$1
4000mah 142.86mah/$1
6600mah 126.44mah/$1
And the 3000?Why u didnt check this option?
Anyway, we will wait for comments after U use it.
I ordered the monoprice charger. Relatively small and light plus it works! I found the connection between the charger and my nook and phone were a bit of a pain to use while traveling. Therefor, I ordered the ebay cable.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.
Here are the links again...

Given your estimated "true" capacity of your 2400mah charger at 1229mah, does it make sense to use it as a charger for the NC? The NC has a 4000mah battery will having the charger make a significant difference? Of course the same question can be asked about my purchase of the monoprice 2800mah charger.I got my 2400mah charger. It worked with my Epic and Nook without causing touch screen issues. New lithium batteries need a few cycles for all the capacity to be realized, so I did about 5 or 6 50% discharges over the past week. So here's my test result:
At 25% batteries left in my Epic (1500mah lipo), it charges it to 100% taking 2.5 hrs. That makes it around 450ma charging current by my estimate, not counting efficiency. If I take 80% efficiency in the phone charging circuit, that makes it around 560ma charging current.
The charger has 3 leds which blinks in sequence according to capacity during charging. I'm assuming 3 led means full, 2 is at 66%, and 1 at 33%. Since you should NEVER discharge a lithium battery beyond 80% of their rated capacity, I stop discharging it soon after the last led started blinking. Which surprisingly made some interesting math. Assuming 2400mah is the true capacity of the battery in the charger:
2400mah x 80% (never discharge beyond 80%) x 80% (charger circuit efficiency) x 80% (phone charging circuit efficiency) = 1228.8mah.
which incidentally is very close to 1500mah x 75%(my phone stage of charge) =1125mah. Very close to the above! Of course all of the above are without a shred of proof, and it's backed up by flying monkeys and unicorns. But I do know this, the charger will charge my 1500mah Epic from 25% to full without damaging the cell in the charger.
There's my review.
7800mAh Universal External Backup Battery for Mobile Devices, iPod, iPad, iPhone, Kindle, and more
This 7800mAh universal power bank for iPad and various other USB device’s, is an amazing solution for re-charging your devices back up to full capacity. The power bank can charge two devices at the same time, as it has two outputs. These types of battery backups were used to power the flux capacitor inside the Delorean when it was getting low on juice and it can do the same for your high end USB devices that need the same type of charging power.
The power bank is universal and works for Ipad, iPod, iPhone, and other USB devices including phones. Equipped with a one touch battery indication for turning the backup battery on or off for your convenience. Charging the battery is simple and can be charged within 5 hours under their max output, by a PC, a USB wall charger or your car charger.
* The letters on the backup battery, "PoweRocks" Is an indicator that will fuly light up when the backup battery is fully charged, and as the battery runs out of the backup battery, the lights to the letters start going out. So the if the full title, "PoweRocks" is lit up, it would indicate a full charge, while if onlythe "P" or "PoweRocks" is lit up, then the backup battery is almost out of power.
Note: USB I is a tablet charging port with 1000mah output/ 2.1 amps - and USB II as a 500mah for phone outputs. Standby time, talk time, internet use, audio playback and video playback all vary per device and usage.
Given your estimated "true" capacity of your 2400mah charger at 1229mah, does it make sense to use it as a charger for the NC? The NC has a 4000mah battery will having the charger make a significant difference? Of course the same question can be asked about my purchase of the monoprice 2800mah charger.
This question -- how many more hours, is how I look at the value of external batteries. Sure, you might be stranded somewhere and have 2-3 hours or more to recharge your Nook with an external battery, but a much more important factor for me is how long I can extend the battery life of my Nook with an external battery. As I wrote in a similar thread some time ago, 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 flying 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).I didnt see that somewhere.
So, how many hours more can you use nook with this battery?

XP2000 looks great. Can I assume the XP8000 would be even better? Yeah, it weighs more but is rated 8000 mAh vs 2000 for the XP2000.
While we're on the topic the XP2000 is called a "portable charger" and the XP8000 is called an "external battery". Is there really a difference?
I use this with my nook. I can't answer any questions related to workability with Android phones. That's not this forum.I'm interested in a similar charger, but with 2400mah.

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?
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.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?
Just a heads-up. When I searched this manufacturer and model number on Amazon the product that came up, a small device external charger, had the worst reviews I've ever seen on Amazon. Ten reviews, all from different people, over a 2 1/2 year period, every one a one-star (lowest) rating with damning commentary. Maybe I found the wrong product, maybe the reviewers are wrong, but FYI.+1 I did the same thing with my original ipod touch. I bought Just Wireless SKU 10047 at Target on clearance awhile back. It says Output 5V=1A. Does anyone have any experience with how long this one will last playing back videos and what Battery level the nook will be at if it starts at 100? I have the 4 LED's full charge and can connect it to my nook with its micro usb connection. Just have not tried to drain it yet?
