NC slow battery charge

Only had my Nook Color couple days, and am currently running latest Honeycomb from SD card. Does anyone else notice that it is very slow to charge even on the AC adapter? Thanks.

I noticed that. It also seems to suck the battery dry in about twice the time. But, what can we expect. It's REALLY early code, needs to be tailored to the nook hardware.

Are you using the Official Cable and Brick that came with it?
It should take about 3hours with those for Recharge, if its alot over that You might have a defected cable or brick.
If your using a Standard Microusb cable. then the Nook color will charge extremely slow, and wont even show its charging, because the cable that comes with it, has two extra pins that are used to provide extra power, I think the Nook charger puts out 2amps while a standard usb is only 500ma.

Thanks for the tip. Had no idea the cable included was different from a standard usb micro cable (which I have been using to charge).

Heh... It'll only charge at .5A with a standard cable. 1.9A with the Nook Cable. It has two extra sets of charging pins.

[Q] External Battery

Found this external battery with good pricing. Anyone tried this? Does it work with NC?
monoprice.com/products/product.asp?c_id=108&cp_id=10833&cs_id=1083311&p_id=7664&seq=1&format=4#feedback

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.
I ordered that cable yesterday, so when I get it (from China) I'll let you know whether it works or not.

Ok. I got that battery from Monoprice, and it charges my nook without any hassle.
Just need to be a little bit precise on plugging it into the micro USB female on the nook.

I'm interested in a similar charger, but with 2400mah.
http://www.dealextreme.com/p/2400ma...a-cable-for-htc-desire-g5-samsung-i9000-57905
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.

I use this with my nook. I can't answer any questions related to workability with Android phones. That's not this forum.
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. It will also charge my nook when it's not plugged into the wall (it is a battery, after all). In either situation, my nook is completely usable when connected to this.
I use this battery with my proprietary nook charging cable.

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 bigger the better right?

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.

[Q] Nook Charger - Must have or nice to have?

I live in Africa but will be travelling home for Christmas and recently purchased a refurbished Nook Color from B&N via ebay. I have read that the charger and cable are special and of pretty poor quality. My question is this...
If I have my Nook Color in Zambia and the power adapter and/or cable quit working am I completely hosed or can a normal micro-USB charge it (albeit more slowly)?
My experience with phones tells me that if the battery is completely depleted, it sometimes needs the OEM charger to charge, is this the case with the Nook Color? Can a basic microUSB charge a completely dead Nook Color?
Thanks. I would have no problem buying a backup if the quality weren't so poor. I can leave it charge overnight using the same stuff I use for my other devices.
Thanks.

Hi. I think its a must have. It charges the Nook Color so much faster. You may want to pickup 2 of the special USB cables as well since they're kind of fragile. The micro USB tips are easy to break and in Africa, a replacement is not easy to get.
You cannot use a standard USB cable in the Nook charger since its slightly different and pumps much more amps through it than the normal micro USB cable.

Your second point is just false. A standard UBS cable (micro-USB) won't damage the nook. Instead of pushing more amperage it actually does less...it doesn't reach the high-power section within the nook anyway.
Computer USB ports can't push more than 500 mA safely so they are limited to that. The Nook charger runs at double that and thus charges the nook much faster than plugging it into the computer.
I use the nook cable with a palm wall charger unit with no problems. My nook unit was buzzing so I stopped using it.

Battery Pack for Nook HD

I've tried 2 portable battery packs for the Nook HD, but neither work.
Any recommendations?

The GMP10K from ioGear works with my HD+ (the 1A connection only; the 2.1A connection does not work). On Amazon at http://www.amazon.com/GMP10K-GearPower-Capacity-Station-Smartphones/dp/B00A35KPQQ

This battery pack charges my Nook HD+ from 1.3 A port, dunno if it will work for HD though.

I don't think it's just the battery pack, there are many 2.1A USB chargers that do not work with Nook HD+ as well. I think this is a problematic.

I have the New Trent NT120C and yeah the charging doesn't work on the 2.1A port also. However the 1A port works so I guess that's fine

RAVPower dyanamo on the go 7800 mah port 2 (worked with my nexus 7 and works with the nook hd)

I asked them on Twitter a week or so ago and they stated the 3E works with the Nook HD (+).
The tweet.

Anker works
I've had a Nook HD+ for all of 3 days, but happened to have an Anker Pro, the one that charges 12 volt devices too. It worked really well with the HD+ from the non I-Pad I-Phone charge tap. The Nook HD+ indicated immediately that it was being charged, etc.and it has enough amperage to charge the Nook while it's running.
I also happen to have a New Trent. It does not appear to work with the HD+, though I know it sometimes wouldn't show as charging my Samsung 7+ when it actually was. It also couldn't charge the Samsung Tablet while it was playing videos. It would slow the rate of battery loss, so if I was at 51%, I'd watch a movie and be at 45% instead of 30%.
The New Trent looks better and I like the size better, but the Anker has consistently simply works better. The New Trent's one advantage is that you can charge it via USB port from your laptop, the Anker forces you to carry around their AC adapter. The New Trent is great for cell phones or smaller tablets, but the Anker seems to work with everything, even my Samsung Netbook. Oddly, they're both claiming to output 2 amps at 5.1 volts, but the devices sure respond differently.

there's an offical external battery for the nook HD/HD+. it's not cheap but it works and would probably work fine for other devices too

i have similar concerns regarding the battery for the nook and have reached to nothing productive yet .. it is good that getting some sound options by the posts here

Yes, too bad we just can't use it with a normal charger or cable.

I got a shiny new Anker Astro Mini external battery (3000mAh) as a surprise gift, and it happily charges my Nook HD+

USB Charging made easier...

On a whim, I picked up a USB charging adapter for a Samsung P1000 Galaxy Tab and tried it with my Nook HD. It allows my Nook HD to charge from USB batteries that it refused to acknowledge previously.
The adapter is basically a USB Plug/Socket with a couple of resistors on the inside to emulate the correct voltages on the D+/D- lines. When in use, the Nook HD sees my batteries as AC input. I picked mine up on eBay for around $5 from a seller in CA. DealExtreme has one that is slightly different but should work the same. dx.com/p/usb-2-0-male-to-female-extension-cable-w-data-charger-switch-for-samsung-p7510-more-black-258964
Here is the listing on eBay for the one that I bought. ebay.com/itm/190702898352?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
This will possibly help many like myself who have batteries already that the Nook HD/HD+ just doesn't like.
Hope it helps!!

Just FYI
For those inclined to modify a USB charger or to create a charger cable jumper adapter by modding a spare USB extension cable;
If the Nook sees the two USB data wires tied together and not tied to a voltage through a resistor (i.e., leave floating), the Nook will go to full charge mode.

I have an original P1000 charging cable and it will not fit in the Nook HD that I found. Was hoping to power it up to maybe get some owner info with out having to buy a cable.

I have modified a short extension cable and it works perfectly. Are you sure you've properly short-circuited the D+ and D- pins on the Nook's side of the cable?
