I'm asking this because i just tried a non-branded chinese external battery that has 1A output and it says "MTP initialization" when i plugged the tab..
Any idea which brand works for galaxy tab?
Your battery should work, but you need to buy something like this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130690906449#ht_1611wt_715, to force it to charge.
The ext batt that you have could work if yr tab is shutdown/switched off. You could use the adapter mentioned above, but... your ext batt output is 1A, the adapter increases the std USB current of 500mA to 2A, I wouldn't.
The 1A current is not the rated current for our charger. Its 2A, if you look at the charger really carefully.
If you use the ext battery while using the tab, my guess is it will drain both the ext & int battery at the same time. Or trickle charge when idle... (not sure on that).
Hope it help...

Thanks, the ext battery actually has 2 outputs, 500mA and 1A,
so i can use that adaptor,
but i prefer to use the smaller output for my blackberry..
I'll see if i can find 1A to 2A adaptor..
If I'm not mistaken the normal output for smartphone chargers are 1A, (iphones/ipods, HTCs, samsungs). Not sure abt BB, never use one. U shud check the supplied charger for the current rating. U get 500mA when you connect to a pc usb port, so charges at slower rate.
You can't just create more current with an adapter like that (unless you reduce the voltage, but that wouldn't help anyway).
I suspect that all those adapters are doing is shorting the data pins, which is what is done on most wall chargers. This makes the device think it's plugged into a charger instead of a computer.
I'd probably make my own adapter, but if you don't want to or want it to look a little nicer that should work fine. It won't charge at the same speed as with the wall charger though.
This one works even just straight cable
Im really suprise my old Callpod FuelTank Duo (500mA per port)works perfectly charging my Galaxy Tabs (gTab 7.7 P6800, gTab 8.9 LTE and gTab 10.1 4G)
http://www.geardiary.com/2009/11/16/the-callpod-fueltank-duo-rechargeable-dual-device-power-revie/
But the latest DreamGEAR i.Sound Portable Power Max 16,000 mAh Backup Battery (2.1 Amps on any single port at a time ) which I recently bought doesn't. why? But the i.Sound can charge a more power hungry iPad3 easy.
http://www.ilounge.com/index.php/re...-portable-power-max-16000-mah-backup-battery/
Im really confuse now and still wont be able to let go of my vintage FuelTank Duo because of this reason.

I just ordered this and will try. I also found this one and ordered one also, hopefully this will solve the charging issues using a external battery power pack
http://www.ebay.ca/itm/Micro-USB-Fe...s=63&clkid=8973626299242376794#ht_2635wt_1037
Yes that adapter is what i needed to use to get my Mypal/Energizer 18000mAh to work w/ my 7.7.
This adapter is no longer available, can someone post a link for this item pls?
I have a Mophie Juice Pack that charges up my 7.7 (and most other devices) just fine.
http://www.amazon.com/Mophie-Powerstation-4000mAh-External-BlackBerry/dp/B005OW4BFE/ref=pd_sim_e_2
The 7.7 seems to be problem in this regard. This one doesn't work either
http://club.dx.com/reviews/text/53689
Which is very odd as it works fine with my Dell Streak, in itself a difficult phone to find an external battery pack for.
I hope we get sufficient contributors so we can build a database on this.

I have just finished testing a generic Zagg type item similar to this

The top outlet designated "Optimised Charge" doesn't work but the lower outlet designated "General" does. Albeit very slowly, 1% every 20 minutes.
This is not an external battery that I would recommend in any event. It self depletes from 100% to zero in 7 days just sitting in a bag waiting to be used.

If edan1979 says it works with the 7.7 then that will be good enough for me to get one. Awesome capacity too.
yup its the same one... can recharge 2 times... but i'm using it with my other device... working well..
From what I could find, it seems that Yoobao have upgraded the Powerbank 11200mAh to the Thunder Powerbank YB-651 13,000mAh.
I have just bought a YB-651 13000mAh from Maikai UK.
There are two charging outlets, the one that works for my 7.7 Tab is USB 1 DC5v-1A and this charges at a similar speed to the Samsung wall adapter.
The other outlet USB 2 DC5v-1.5A - designated for iPhone, iPad and Tablet PC - doesn't appear to be compatible.
It is a funny old game this, why do some battery packs work with the Tab 7.7 but not others.
Just bought momax ipower pro for galaxy tab.comes with 5v 2 amp and 5v 1 amp outlets.
Also came with 2 micro usb cables and a galaxy tab to micro usb adapter..
2 Amp out let works great....

Thanks

I'm not sure if it will because I know for a fact that the USB AC adapter that ships with the iPad 2 does not work with the Samsung USB cable for charging (well, it kinda does, but its that slow trickle charge). I figure that the means that both companies use to get the extra juice flowing over the USB cable are different somehow.

It is. You can get a charging adapter off of DealExtreme, or make one yourself (read the "make your own cables" thread in Accessories, and look at the Universal Charging schematic)
I have a cigarette lighter USB adapter that kicks out 1500 mAhs, and it's enough to charge the Tab 10.1. Since this thing has more than that on tap, it's a fairly safe bet that it will be able to charge it as well.
..
thanks for the info guys. I did order charging adapter cable from dealextreme. I'm going to order this external battery pack and see. Should i get the 5000mAh or the 11000mAh?
Has anyone found a portable Battery pack that we can use on the TF? I have several that I have used for my iPhone and my old iPad2 but all are only 5v. is there one out there that can charge out TF or is the keyboard dock the only way to go for extra Battery?
There are several battery packs used for notebook computers that will work listed on Amazon. Just be sure they have a 12Volt output. EverReady had as battery pack that will also work but you will need an adapter provided by them. The key is that you need an output of 12 to 15 volts to charge the TF or Keyboard. You might read Devcake's post on a DIY charger for the TF as information on the voltages required to charge the TF. There is also a post on external batteries that might help.

I just saw this while I'm looking for a battery pack.
On a german page I found this interesting:
w w w.intecro.de/XTPower-MP-16000-Powerbank-mobiler-Akku-mit-16000mAh-fuer-Laptop-Handy-iPhone-iPod-iPad-PDA-MP3-Player-mit-20-Adaptern
(can'f find an english page for this product)
Could I use this one by using an adapter?
I just got an Anker Astro3 10000mAh battery pack. I plan to use it while camping this summer, mainly to charge a phone, but occasionally to charge my tablet.
It is intended to charge 5V USB devices, and has two USB ports. It also has a 12 volt port. The adapters for the 12 volt port, of course, do not work with USB or the Transformer. So I made an adapter, and I am good to go now for charging the tablet.
The battery pack charges from a 12 volt wall charger. I have also made an adapter to charge it from the 12 volts on my motorcycle. So I will be charging it from the motorcycle during the day when riding, then using it to charge my devices in the evening at the camp. I've already tried it a couple of times, and it worked well.
I tried to charge the battery pack using a solar panel, but the solar panel was far too wimpy. It was like trying to run a house air conditioner from a penlight battery. It may make you feel good to try it, but it isn't going to do much.
So far so good. This is very close to what I need.
The issues I have had to work around are:
1) I want to also charge an in helmet bluetooth intercom from the USB port. But the charge current is so low, the battery pack auto powers off, thinking nothing is plugged in. Not a big deal because I can plug in my phone at the same time. That keeps it turned on until everything is charged, then it auto shuts down.
2) When I charge the Asus Tablet, it doesn't appear to auto shut down. Just the opposite of #1, it looks like the load stays high enough to never shut down when charging the tablet. This may not really be true, as I have only tried it a couple of times. Also, it isn't good for much more then one and a half charges of the tablet, as expected.
3) You need to figure out your own harness to get the 12 volts to the tablet.
4) No charge cable for a car. I mean this is rated for an input of like 10 to 15 volts, or some such. This thing is GREAT for charging portable devices. Charging it from a car is as simple as a cable, but there isn't one.
Over all this charger is a winner. At right around $55 US, I recommend it, if you can fabricate a plug for charging the Transformer.
Try a 12V UPS type battery along with a 2A fuse and adapters. It only costs about $20 or so. Plan on using only 50% of its capacity and recharge often to get the most life out of it.

For me, this is actually what I use now. But it has issues.
One is simply that it is large. I carry it in the trailer that I tow behind the motorcycle, so it is OK, but a bit too large and heavy. It is a gel cell that has about a 48 WattHr capacity. LiIon has a a lot less and weight. In this case, it has about the same capacity, in a very small light weight package.
The other problem is charging the lead acid battery is an issue. I need to carry a AC charger and find AC when camping. I put a diode/resistor combo in the trailer and tapped off of the taillights. but by the time the weak motorcycle voltage gets to the taillights, add in the diode and other losses, and I'm lucky to see 13 volts at the battery. Not enough to charge it very well. The LiIon pack I use has the supply built in to charge properly from +12.
So I've tossed the lead brick battery (literally) and upgraded to a portable LiIon pack. So far so good.
This is what I use "Portable 12V DC USB 5V Rechargeable Lithium Li-ion Battery Pack for CCTV Camera" search on ebay, you can get one up to 13AH
I got a 3.8AH version for $16 , Dimension: 9.2cm X 6.0cm X 3.0cm
Outout rated 5V (5.8AH) and 12.8V (3.8AH)
small modification because the charger is NON-US wall plug, I just pull the plug pin out and add in a regular power cord cut off from an old appliance
Keep the USB plug for 5V use, cut the 12V DC cable and connect it to a female USB cable (pin 1 and pin 4) , then you can plug in the Asus usb/charge cable directly and charge or power the Asus

Alot has been said about the quality of various batteries that we are all looking at for our devices...however very little about the different chargers that are out there.
I thought my charger that I bought was defective cause I let it charge overnight and it wasn't fully charged. That is not the case.
The Charger that the Note comes with charges at 1A. Most of these external battery only chargers charge at 350mA.
Take a look at this calculator:
http://www.csgnetwork.com/batterychgcalc.html
Using the link to the calculator above, you should expect a 2600mAh battery to fully charge using one of these cheap chargers in about 9 HOURS!! The charger that the note comes with should expect about 3.4 hours. That's a huge difference in charge time!!
So be sure to take a look at the output of these chargers before you get too excited and purchase one. If it takes you 24 hours to charge a battery, what good is it to you?
Thanks for the battery reference URL.
This is basically another scenario of 'you get what you pay for..'
It seems to often apply to batteries and chargers.
Whereas for like cases, you have a better chance of actually saving money and getting quality at the same time.

So I guess for battery longevity, you should use a 500 mA charger (the typical USB output). That way it doesn't charge it too quick (and overheat the battery).

No, actually. Lithium ion batteries, unlike nickle-cadium batteries actually perform and last better with short, fast charges. Android's battery stats are helped by a few full cycles, but it is not better for the battery to full cycle or slow charge.

*I am not an electrical expert, I just play one on TV.*
There are standards for USB outs. Just Google the standard. That said, there is USB1, USB2, and now USB3. Check your motherboard to see which one you have. There is also a newish thing on motherboards that will do a rapid charge by changing a setting on the BIOS. That's what i got off the top of my head. Do a little research.
As was pointed out on another thread, the Note looks for a low resistance/short between pins 2 and 3 of the USB cable. If it sees the low resistance, it enables a high current charge; otherwise, it sticks with USB standard charge of less than 500 ma. The 2/3 pin setup is not true of USB connections to a computer. The Note power adapter is set up this way to do a fast charge. Most chargers and portable battery chargers leave pins 2 and 3 unconnected, so they will not fast charge a Note even if they can supply 1A.
I purchased a Scosche 5000 mah battery with USB ports for charging Ipads, Iphones, and other devices. It also charges a Galaxy Tab with a special USB adapter plug. I tried the Tab adapter with my new Note and it was charging at 5 percent charged every ten minutes or so. Without the USB adapter, the Note charged at 2 percent every ten minutes or so. Without the adapter, the Note displays an MTP initialization notification. With the adapter, there is no MTP notification.
The Scosche battery is a big improvement over older Trent 5000 mah batteries. There is a push button to turn the Scosche battery on. The battery will turn off if no device is attached or it the device is fully charged. One of the ports can output 2.1A for an Ipad. The Trent battery would run down if it was left on.
Staples carries the Scosche battery for $80. I used a $29 online coupon from Staples that expires 3/5/2012.
I did not see anywhere on the Scosche website where they sell the Tab adapter by itself.

Do you have a model number on that USB adapter? Maybe in the instructions?
There is only the name Scosche on the adapter. The guide only calls it the Galaxy Tab adapter.

What does an "MTP initialization notification" look like on the Note? How do I identify it?
If I don't see it when charging, does that mean it's getting a fast charge for sure, or just that it might be?

How exactly would you use a multimeter to do this? From what I've seen, they have two contacts -- where would you stick those? Or is there some kind of micro USB conversion thingy to use with a multimeter?

Cut a USB cable, and strip a portion of the power wires. Set the multimeter to a 10A DC current scale (assuming it supports 10A, but most craftsman and up do, with common and a 10A lead), disconnect the plug, attach common to negative wire and positive to positive wire, gator clips or something, then plug it in and read it. The current support and time it can be on depends on the multimeter. Mine does up to 10A for Max 30 sec.

I noticed a lot of people want a fast charger for the Note. This charger is for the Touchpad. I have this and it works really well. It charges faster than the OEM charger that came with the Note.
Not to mention, it is on sale right now for less than $5. Go grab one. From past experience, I used this at 15% battery life and charged for an hour and I was back over to 80%.:victory:

Yes, it is a micro USB cable. One end is USB and other is micro USB. The cable length is longer than most phone cables. I haven't measured it, but from my plug to my desk, I still have excess cable compared to the original one from the phone.
Thank you, getting one!
This have been discussed hundreds time before....
That 1amp is the output of the charger which forwards the current to kernel of the device... NOTE can only intake 1 amp current... ( remove your battery and read the dam sticker :thumbup
Even though you will supply 2 3 4 5 amp... The maximum in would be 1 amp ONLY...
SECONDLY, micro usb cables have a restriction of carrying current... They cannot pass more than 1 amp current successfully... Therefore galaxy tab series does not come with micro usb slots....
Lastly my recommendation would be NOT to waste money on any other chargers...

It has been discussed, but it DOES charge faster than a conventional 1amp charger. If you don't have the charger and have nothing to compare with, then I don't think you can say it does not work.
Go check FCC about the charge. Also, the cables provided DOES carry a 2amp charge. Our note can handle fast charging but throttles down to a slower charging rate after 80%.
having a micro usb slot or not have a micro usb slot has nothing to do with the current it can handle.
Ipads and Iphones have the same connector but yet one has a 1amp charger and the other a 2amp charger.

It has been discussed, but it DOES charge faster than a conventional 1amp charger. If you don't have the charger and have nothing to compare with, then I don't think you can say it does not work.
Go check FCC about the charge. Also, the cables provided DOES carry a 2amp charge. Our note can handle fast charging but throttles down to a slower charging rate after 80%.
having a micro usb slot or not have a micro usb slot has nothing to do with the current it can handle.
Ipads and Iphones have the same connector but yet one has a 1amp charger and the other a 2amp charger.

Well its $5, which is not worth this discussion, I'll gladly give this money even for the stock samsung charger.

Firstly, I have tried to use with a 2amp charger that came with my SGT P1000.. NO DIFFERENCE...
SECONDLY, PULL OUT BATTERY AND READ!
Google for micro usb cable max output... You will get your answers...

You don't have to get your panties in a twist. Rather than just read forums and assume the worst of everything try it for yourself. I've tried both and it is faster. Just trying to help my fellow Note users to get the best out of their phones.
btw, what are you screaming about pull out the battery and read? you tell me what you want us to know. RATED: 3.7V; 1500mA... WOW ok that proves your point...sigh:silly:

This have been discussed hundreds time before....
That 1amp is the output of the charger which forwards the current to kernel of the device... NOTE can only intake 1 amp current... ( remove your battery and read the dam sticker :thumbup
Even though you will supply 2 3 4 5 amp... The maximum in would be 1 amp ONLY...
SECONDLY, micro usb cables have a restriction of carrying current... They cannot pass more than 1 amp current successfully... Therefore galaxy tab series does not come with micro usb slots....
Lastly my recommendation would be NOT to waste money on any other chargers...

As an HP TouchPad owner, I can confirm that the cable provided with the charger are 'special'. My TP will not charge with any other MicroUSB cable connected to the official charger, the same cables which won't charge the TP will charge the Note. (I also own the HP touchstone dock, which the TP spends most of it's life sitting on.)

I have four different wall chargers, including two of this HP barrel adapter (one that came with the TouchPad, one that came with the Touchstone). With the supplied cable, it does charge the TouchPad very quickly. From webOS, the net charge rate is about 1.6 A with the screen on, so probably close to 2 A coming out the USB port.
However, when you plug a Note into this charger, the Note will still only draw 1 A. I have other AC chargers that are also able to supply 1 A to the Note, so in that respect this HP charger isn't anything special. However, it is only $5, which is a good deal.

I've found that the microUSB cable that comes with the Note, when paired with the HP TouchPad's AC charger, will supply 2 A. At least, that's what the OS reports: /sys/devices/platform/usb_gadget/current-mA shows "2000". Plugging the TouchPad into the Note's AC charger shows a value of "900". Plugging it into my laptop's USB port drops that value down to "500", as expected.
I bought two a week ago off Amazon for $10 each. $5 each with free shipping is a steal. I picked up three more. Thanks for posting this deal. I get 1A charging with either the stock charger or TP charger. I like to have a few extra chargers to sprinkle around at home or work (for my Note and the other devices I own that charge off USB.... including a TP).
deliriousbb said:
Yes, it is a micro USB cable. One end is USB and other is micro USB. The cable length is longer than most phone cables. I haven't measured it, but from my plug to my desk, I still have excess cable compared to the original one from the phone.

When you charge your phone using this HP microUSB cable, do you have issue with NO DEEP SLEEP when unplugging the Note from the charger?
There has been issues reported in XDA where, depending on the USB cables used to charge the Note (connected to computer OR power charger), if you unplug the Note, it will not go DEEP SLEEP, causing significant power drain.
This does NOT happen when the Note is charged using the cable that came with the Note.
Download Current Widget from the play store. Add widget to home screen and you will realize that your phone is not charging any more than 1 amp as designed.
Try the usb out from your pc and you will see about half an amp.

I have the galaxy tab brick charger the HP touch pad charger and my note charging brick....the touchpad charger works faster...but I feel like it doesn't get fully charged..seems to die faster?. I used the galaxy tab brick...slow to charge warms my phone up nicely...I'd stick with the original note charger.

I charge my Note overnight using my Touchpad's MicroUSB cable plugged into the Samsung charger, and I don't experience any difference in power drain.
Where is that post from the guy who put all these petty arguments to rest with scientific tests of all the various options and results??
Good lord people it's a charger for a phone .. no need to get so heated!
(unlike my stock charger.. which gets very heated!)
great price!!!
ordered 3 of them
the price is way cheaper than just a single micro usb cable shipped from other stores
i have 3 already
1 at work, 2 for home.
definitely faster than OEM. I charge overnight, no issues. had for around 5-6 months now. and i can use the phone while charging.
fact is that it DOES charge faster.
i recommend it
WOW***
Great price I bought 2!
The Xperia Tablet Z is a notoriously slow charger and won't charge over USB (from what I've heard, I don't have mine yet). Does anyone know of a portable charger or power pack that'll work with it?
Ideally one available in Europe.
Cheers.

The Xperia Tablet Z is supplied with a charger that connects to its USB port; so, the XTZ will charge via its USB port.
If you attempt to charge the tablet via a computer's USB port, that port must be capable of supplying enough charging amperes, otherwise, the tablet will not charge. Standard USB 2.0 ports supply up to 500 mA and standard USB 3.0 ports supply up 900 mA, neither of which is truly enough amperes to charge the tablet. USB ports on computers that are specifically designed for charging devices usually supply 1500 mA (1.5 A) or more. Some manufacturers mark these types of USB ports with a lightening bolt symbol.
As for portable chargers, I have not used any except for chargers that fit in my automobile's power plug (cigarette lighter plug).

Any halfway recent (read: last 5 years) USB charger will work with it. Be it the one Sony supplies with the tablet, an iPad charger...or one for the Galaxy Note 2.
USB chargers are standardized, you need a "special" one nowadays about as much as you need a "special" socket for a device with a power plug.
The only difference is that we have weaker and stronger chargers, but this does not limit their usability. If you use a weak charger your device will charge slower, if you use a charger with an higher maximum power as your device needs it will expl nothing bad will happen either, it won't take more from the charger than it can handle.
Personally I bought (since I need the original 1.5A charger for the dock) a 2A Samsung charger for travelling. I think it is the same as the Galaxy Note 2 uses, which you already have.
Oh, and it charges with the 2A one over USB also around 30% faster than with Sonys 1.5A.

Maybe I'm not being clear.
Portable power supply. With a battery. One that puts out enough power to actually use the XTZ while it's charging, even if doing so only keeps the battery the same rather than actually charging it.
Can anyone recommend anything?
I know it uses a standard micro USB connector to charge but I've heard it won't charge from most PCs as they don't put out enough power. My understanding of many portable chargers is that they also don't put out a great deal of power unless specifically designed for laptops and the like. I don't know if the tablet's needs are quite that, but I'm looking for anyone who has experience using a battery pack with it and if anyone has any recommendations.
Or am I being silly and it'll work with anything capable of charging any tablet?
Thanks.

It should. The XTZs battery isn't exactly high capacity as tablets go. The Nexus 10 has a 50% bigger one and the iPad3/4 one is almost twice as large.
The principle of power packs is in the end identical as that of basic USB chargers, even a 500mA one will charge the XTZ, but it will take around 15 hours for that (and around 24+ hours to charge an iPad). It isn't a question of "working", but of "working how fast". But, as said, the XDZ hasn't exactly an huge battery, so if anything it will charge faster than other Tablets.
Assuming you do not use it, that is. It is quite possible to discharge it as fast a 3A/hour if you use maximum screen brightness and CPU intensive tasks. But you can discharge other Tablets faster than you can charge them as well.
So what to use - same principle as with USB chargers, pick any. It does not matter if its power comes from a power plug or batteries. If ti works for one USB device it will work for all. What matters is it's maximum A output. One with 2A should be able to charge the XTZ in 4.5 hours, one with 1.5A in 6 hours, and so on...

Yeah, I'm looking for something that charges the XTZ faster than (or as fast as) it discharges.

The Sony CPF2LS USB Portable Power Supply with 7000 mAh Battery charges at 1.5 amps so it should work for you. I'd post a link to Amazon, but, alas, I can't. It's around 63 bucks.

There is a slew of chargers that will charge it. You can use laptop USB, but like mentioned if you use it while charging it will drain
To solve this problem you simply need to have a portable charger that will put out at least 1.5amp(which is what the tablet charges at if im not mistaken).
So plenty are on amazon or ebay which you should have access to in europe
I use powergen ,they work well and is good quailty. Like either of these will workbigger mah will make the charger simply last longer)

Key thing is to simply look for the amerpage it puts out before you buy, that's how you know if it will charge and use the tablet at the same time. I can sucessfully do both using my car charger(2amp made for iphones) and my Powergen

The thing is this entirely depends how you use it. It is quite possible to use it in such a way that you would need a 3A charger to stop it from discharging. I do not think such one exists nor that the battery can accept such a charge.
So AFAIK a charger (be it a power plug or battery one) which stops it from discharging under all kinds of usage scenarios does not exist.
Therefore there is no answer to you "which charger I should use" question, only that the more A a charger puts out, the more usage scenarios will be covered (as in "will charge tablet while using it that way") by it.
Test how fast the Tablet discharges (without charging it) when you use it the way you plan to while using your charger. That will give you an indicator what kind of power you need. I.e. if it takes 12 hours even only a 0.5A charger will work, if it takes 2 hours you would need a 3A charger, which likely doesn't exists.
Im using an innergie charger that gives 2.1 amps and it charges a little faster than the 1.5a that came with it!

You know that that charger will only charge around 66% of the XTZs battery, though?
(Effective maximum capacity ~4A (see "attrition factor" explained in 2nd review), XTZs battery: 6A)
I am using my Samsung Note2 charger that states 2A.
Charges alot faster so for people with other chargers I should check samsung chargers haha.
Heya,
