[Q] external battery pack for A7? - A7 Accessories

Does anyone know of an external battery pack that would work with the
A7? I read that a netbook power supply would charge it so I think an external battery for a 19V netbook would work. Any ideas?

Yes the PAL Energizer 8000 (costs about $90) supplies 19V power.

Adapter-free Charger and Sync cables?

I'm looking for cables for charging and syncing my titan without the stupid adapters that come with it. I hate the combined plug for the headphones adn mini-usb. I don't want to have to tote around the adapter. Does anybody know where I can find these? I'd like a car charger, a sync cable, and maybe a wall plug charger. All depends on the price for what and how much I buy.
no adapter needed
You can directly plug the charger into the phone, the only reason the adapter has an odd shape is to keep you from plugging it into other usb devices.
I use my car charger from my 6700 with no problem.
I thought the same as you, then figured out you can plug mini usb directly into phone.
wow, I feel a little stupid right now, but just a little bit because that wasn't exactly obvious. I'm really happy about that now though. That means the only real point of frustration is having to use two adapters to get to normal headphones or buy a new adapter. I'm just happy I can car charge and use a normal synce cable with no adapter. Thanks man, that's a big help.
I wouldnt charge my mogul in the car cause its so much easier to weaken your batter when charging inside a car

Can you explain this? I'm an electrical engineer, so I should understand any reasoning that you know of for this. I would think that all the charger is is a DC plug with a regulator to keep it from going over the rated 3.7 volts. Is the current higher than the wall plug? I don't get how this would work?

Only thing I could think of is that it charges at a higher amperage and that in turn makes the battery hotter. I compared my HTC wall charger with the USB car adapter I use and they have the same current and voltage.

[Q] GPS, batteries and car chargers

Hey guys
Have got the GPS working properly on my SGS (props to those who figured that out) but I've noticed something a little concerning.
When I'm running google navigation that battery continues to run down, even when its plugged into my car charger. It'll survive for a good few hours, but it seems a bit bad to arrive at wherever I'm going and need to borrow a mains charger when I get there.
Anyways, I'm normally running bluetooth to my jabra speakerphone/fm transmitter, but nothing else that should agitate the battery too much, and with GPS turned off, it happily charges even with the screen perma-lit.
Im running stock JG5, and my dash charger consists of a cigarette lighter to USB converter and the stock USB cable.
Any thoughts on whats up with this would be greatly appreciated!
The phone is probably consuming more power then the 500 mah charger can provide. You need a dedicated mini usb for charging, the ones that actually are usb cables only provide half power

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.

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.

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.

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.

[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.

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.
Here are the links again...

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.
