External backup battery - Nook Color Accessories

I'm looking for a backup battery. Has anyone come across any that have enough juice to put a good charge on the nook? I know those little 400mah batteries can charge the nook but how long will 400mah last? I'm looking for something that can give it a 50%+ charge

This what you are looking for? That would get you about 1.5 charges.
This would give you about 1 charge.

The Zagg one would be perfect but its $100! I dont want to spend over $50 guess I should have said that.
I will look into the other one you posted thanks
EDIT: The energizer one looks great!! I am probably going to order one. Thanks a lot!

I didn't notice an amp output on the energizer. NC is looking for 1900 mA for proper charging. That first gizmo is dead perfect but 100 beans is a bit outside my budget too. I have a 4400 mah battery that does 1000 mA output- i wonder if that would add a few hours to my NC? I take very long flights often.

If I remember right The stock nook color charger is rated at 1.9A which is 1950mah. The energizer website lists the battery linked above as 1750mah which should work great.

Check out Brunton Chargers:
http://www.rei.com/category/40006509

I went with this unit, http://www.amazon.com/gp/product/B0038VQET4/ref=oss_product
It's under $40 and provides a full charge.

What is the recommended way to test the time-to-charge? There are two issues that I see in capturing this data.
1) You really shouldn't run the thing dry - I mean it won't even boot with the power adapter plugged in until it has a little juice in the battery. I suppose youl could to drain it to 25% then charge from there. Then add 25% to whatever your time-to-full is?
2) how can you tell how long this thing takes to charge if you're asleep. Is there a log file which gets updated with charging events? Or some specific app for such things?

A little big but if you want to keep your mobile devices running for a long time try this:
http://www.amazon.com/gp/product/B003ZBZ64Q/ref=oss_product
It charges my NC and G2 3 times each and change. Especially useful when using the wireless tethering on the G2 to keep the NC online.

I've been running my NC entirely from a Tekkeon MyPower MP3450 with the MP3450-10 add-on pack for two full days of heavy usage (probably around 18 hours or so of actual use) and the MyPower is only drained down half-way while keeping the NC topped off at 100%. I'll be back with an update in another couple of days when I expect it to be empty.
Edit: Yep, I got four days of heavy usage (probably equivalent to four full recharges of the NC) from the Tekkeon pack. I bought it to keep my laptop running on long flights, but it's nice to know I'll be able to read if the power goes out for a few days.

Will using a standard usb cable with these backup batteries still only charge at .5A? If I use the stock nc cable on the energizer battery linked above will it damage the battery?

Have you looked at Monoprice? They have battery backups. I haven't personally ordered one of these (yet...need one for my evo) but I've ordered lots of stuff from them and everything has worked very well.

That's a decent price. Have you had much of a chance to test the unit?

With the NC's built-in battery rated at 4000 mAh, this battery should be able to completely recharge an NC. Or give you an additional ~8+ power-on hours.

I have a version of one of those, works fine except it's hard to keep in place. If you get one, also get a M-F cable as well.

I went with THIS deal to get THIS battery pack for free. Not expecting much, but will post back when I have some results.

When I bought mine, I just Googled "buy micro usb extension." I just did it again and found this in seconds...
http://www.usbfirewire.com/Parts/rr-mcb-ext-xxg.html
A Micro B male fits both Micro A and B female, which is why nobody bothers selling Micro A male cables... It would be less compatible with nothing to gain.

Thanks..I am surprised Monoprice doesnt carry it. Anywho, after shipping + cost of that cable + 2 x 2800 mAh, it was cheaper to buy the one from Amazon.

HTC HD2 Battery Bank BB G300 & Screen Protector (P300)

I just ordered this from Expansys. I had a APC unit (similar) to this previously, but it has died on me.
It says that it can recharge the HD2 three times. It comes with both USB and Micro USB connections, allowing it to be used with other USB devices.

Ordered this along with the screen protectors (P300) from Expansys earlier today. Just got email saying that they have shipped from Singapore already.

Hey,
What I do is carry a spare charged battery which is small and light. I keep it in Nike waterproof small pouch which is designed to clip to trainer shoe laces... I just keep it in my jean's pocket...
You can get spare batteries with an exteral charger on ebay and whilst these products generally are made in China and sold through Hong Kong, I have never had any problems. I have uses the same arrangment for HTC pda's since my first "HTC" Qtek 9100 all those ROM flashes ago...
Rgs,
J
Yeah, had one from my devices as well. I wanted something that could provide longer life for long trips vs. carrying a bunch of batteries.
Not sure how those battery units will work with HD2, slow charge I suspect. The HD2 can charge from either a 500mA or a 1A source. I suspect it charges faster rfom the 1A source, which this unit provides.
The G300 battery pack is good value when compared to the price of a spare HTC battery for the HD2
I ordered a whole package from Power Traveller including the solar panels. Have not tested it yet on my HD2 but it should all work out. It works well on my other cell phone, mp3 player etc.

I just received my items from Expansys, the battery is incredible - really small. To think that the battery can charge the HD2 three complete times on a single charge (2680mAh).

Nice! Did you actually test the 3 times charging? I have something similar with rechargeable AA batteries but because it also runs from the battery while charging I could only get one charge while it had triple power as the phone.

I have let it charge off AC, uses the Mini USB port for this - not micro, for upwards of six hours so far. I am going to test it starting tomorrow, leaving on charge over night. I will drain the HD2 by playing a video as long at it will let me, then if there's any power left I'll just play games on it until gone.
Actually, I'll start in the next few minutes as I hadn't planned on going to bed anyway.
I'll also stick the screen protector on and see how that goes,

OK, I used the Battery Bank (BB G300) last night to rechage my HD2. After unpacking it and charging for four hours it only would recharge my HD2 one and a half times. According to the paperwork it should charge the HD2 three times.
So, I am going to recharge the Battery Bank overnight and try again.

The instructions say something about charging 5-6 hours on AC adaptor or 10-11 hours on USB.
By the way I got one too, thanks to Nighthawk for the tip.
SO is this something like an external battery pack? can you still use the phone while charging through this? (obviously I would assume) so it's just a bigger version of the external battery you hook up through usb if you were on the plane for example. and theoretically replace carrying 3 spare batteries?
oh am I on crack and thinking of something entirely different?

The HTC screen protector (P300) is really good. I had to line it up along the long edge of the screen, but it wasn't to difficult to get on.

buy regular AA batteries and just use them.

Well, 4400mAh is a lot more than the HTC one (2680mAh). I personaly like the size and the fact it is an HTC device, but that is just me. If you are happy with what you picked I would stay with it. The only thing I would look for is what the output is. To charge HD2 at full speed you need 1A output, not the normal 500mA that most USB devices use. You can use the 500mA charger, but it takes longer.

The HTC unit has standard USB port as well. The ability to add AA batteries is nice, but I am not in need of this at the moment.

[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.

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.

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] Travel Battery Pack

I am on travel very often and my last experience with my Desire was that when working on the phone with no possibility of charging it, I was left with very little or non battery late afternoon. Any suggestion for a good Travel Battery Pack anyone? One extra charge will do. Thanks
Probably better off getting a spare battery, and charge it up, most easiest way i think instead of carrying aa batteries and charge cases, leads etc.
Just look on ebay and click cheapest first.

i use solar charger it has built in 3000Ma battery you can also charge it from pc or adapter and ready to go with extra power. Have it from ebay for $29
Did anyone test any spare batteries from ebay? Thought of getting some, but not sure if it is worth it or not (the charge should at least be as high as the stock battery's) .
Got this few days ago from a china online retailer. Good construction and nice pocketable size. Slightly heavier than LG2X & about 20% thicker. Comes with 0.5A & 1A USB output.
So far, on 0.5A output, no in-charger lock ups yet - which I do get from some AC chargers.
Priced upwards of US$35. Google for "5000mah Power Bank".
will LG come out with an extended battery for the Optimus 2X ?
If they made 2 models. one like we have with a 1500 battery and one that is 1.2-1.4X thicker with lets say a 3000 battery I think almost everybody would choose the slightly thicker 3000 battery model.
These devices are small enough as it is, they should now stop trying to make them smaller as they are surely limited by the screen size, and make them last longer.
I had a Del Axim X50v a few years back that I brought an extended battery and battery cover for, this actually made the device feel better in the hand.
I think the future is not far... for batteries that are either running on gas or like these ones which can be fully charged in less than 3 min. http://green.autoblog.com/2011/03/23/new-battery-technology-electric-vehicles-recharge-minutes/

Only tested twice from over 70% to full on 0.5A. Took longer than using AC adapter. Tried it once on 1A but got a bit hot quite quickly, so I switched over to 0.5A. Also, it takes a while to charge the pack itself from partial empty to full on 1A AC adapter - so I am guessing the 5000mah claim is reasonably accurate.
I bought this item from DealExtreme.
2200mAh Rechargeable Portable Emergency Power with Phone Adapters
SKU: 23734
It works fine, but the input broke after some uses and I had to fix it.
Energizer works best for me... as LG P990 wouldn't last a day with WiFi and 3G active... i have XP2000 and it works great!, the free tip for life is a welcome bonus... I'd post the link but since am a newbie, i cant.
please google Energizer Energi to go or energizer XP2000

External Battery Pack

For those that want to be sure they can make long trips without running down their battery, try this battery pack. Packs with only about 10% of this capacity sell at this price. 30000mah for less than $25. Notice that that is 30000 and not just 3000.
I won't guarantee their stated capacity, but I'm still trying to run down the one I got last week. Once I succeed in getting it discharged to the point where the internal N7 battery takes over, I'll post the result.
It's from China, I doubt very much that the actual rating is even close to the 30000mAh stated.
Also I see from the label that they say 5v input and 5v out?? it's not possible to fully charge a 5v battery with a 5v charger, the input voltage needs to be higher.
Looking at the sellers negative/neutral feedback most of the complaints seem to be about cheap and shoddy items which doesn't bode well for what you'd get.

Ipads are made in China. So what? 5v in and out is done all the time via internal switching PS. If you buy one and test it, then your opinion of "shoddy items" might count. As it is, I am testing it and so far the results are quite impressive.
To give you some real world data to work with, I have a 10,000mAh battery pack which will charge the N7 from about 30% to full twice with a bit left over, it's an Anker Astro 3 and quite big which it needs to be to pack in 10 Amps. Once you've had a chance to test yours maybe you can post the results here.

That sounds about right for a 10A pack. I'm still testing mine but I only use it when I'm out. So far, active reading time only amounts to about 4 hours. The tablet has been on for several days but most of the time in sleep mode. So far the battery pack still only has the first of the four LEDs blinking. I'll be using it for several hours today and I'll see what that shows.
As I said, I use it primarily for reading when I'm out but during that time wifi, MagicJack and Groov IP are all running and I do some browsing.
edit: Update. So far the N7 has been on for about a week with about 16hrs of actual use. The battery pack LEDs indicate it still has half charge. I'm quite happy with it.
Hi,that seems to be a cool pack,any new feedback?

Note8 Fastest-charging battery packs?

I'm looking for:
From Amazon US site
Charges Note8 via Fast Charging
Has more than one full Note8 charge
Suggestions of ones you've tested? (URLs?)
(Most of the battery packs I have tried do not provide Fast Charging on Note8.)

How big you looking? I have a 28600 anker that has fast charge. They now have a USB C PD bank that should charge faster than reg USB to C. Have heard RAV are good also. Just putting that out so you can have a choice and compare. I do know one thing I got a 5k version for my son non fast charge. I took it on vacation in July invade we needed a smaller charger on the go. Forgot it was in the suitcase. I pulled it out last week and it still had a full charge. So anker seems to know their stuff.

I was looking around 10Ah, else they get too heavy for just me. For when my family travels, 20-40.
What's the URL/model for your 28600? I don't see any with that value on Amazon.com (oh, the 26800 for $83?)
Thee zerolemon external charger ( not the phone case) works well
I have the Samsung Fast Charge 5100 mAh battery Pack w/ USB-C and it's a great little charger. The screen on charge is 1010mA average and the screen off charge is 2356 mA average. I purchased mine for $37. If it's for yourself and not a gift, you can get the damaged packaging one from Amazon Warehouse deals for $25.91. I love the small size of the charger and the build is great. I also purchased this Soft Felt Pouch for the charger.

That's the one I decided to buy. Silver and Navy Blue have "like new" for $20.
The.passthroigh charging was another strong point in its favor.
Thanks to you, and to all who replied!

Yeah it's the $83 one. I got it on sale for like $60. I will say get what you need. I got the big one because it was a disney trip and we all know smartphones drain fast. Needed the power bank to last all day. Whatever you get they are very handy and not reduced to looking for a plug.

This question for everyone. How long does the battery pack hold its charge? A week, month, longer? My main reason is power outages. My last portable would be dead by the time I actually needed it. Would be nice one held juice 2-3 months. Idk if thats possible? I live in the city. We usually have power outage once every few months. Sucks being in the stone age for 0-6 hours. Depending on what caused it and how much damage.

I have an anker 16000 I got a few years ago.. I charge it may be once every 4 to 6months or so when I go for a long travel... It usually shows more than 80 % even at 4 months...

Ok cool thanks I appreciate it. Anker definitely one of the best battery brands out there. Thats impressive charge hold and perfect for me. Will cruise Amazon and look for best portable Ankrer battery pack. Thanks for the suggestion!
That's how my bank is also. Drain is minimal. I dont know about the rav or others. I only have anker. I am sure the more popular brands has the same performance

I have a romoss sense 6+, 20000mah has a usb c in and out, quick charge 3.0 PD3.0. Very affordable as well. I got mine for 15usd
Heavy power consuming apps and constant usage if WhatsApp and Facebook will definitely drain the battery of any smartphone. And power bank is one of the solutions to this thing who are traveling continuously. That's why I'm using Anker 20100mAh power bank, this power bank charge 2 device simultaneously at faster speeds.
