External Battery - Galaxy Note 3 Accessories

Does somebody knows, is there any external battery for Note 3 with USB 3.0 connection? Or should I Use one battery with micro USB 2.0 like these one:

You can check this RavPower 14000mAh out from amazon. It's got the 3.0 port giving you fast speed and a large capacity power.

Hi mate. I saw this charger on the Amazon but it has not the USB 3.0 connection, just USB 2.0. I need one charger with USB 3.0 connection.
Thanks

For charging a phone it does not matter if its a USB 2.0 or USB 3.0 Those things only matter for data transfer.. cos the transfer rate depends on which usb connection you are using.
For wireless charging, the USB 2.0 charger is it. There is no 3.0 powerbank... cos technically it means nothing. Even if you see one in the description of any power bank.. it doesnt do any good.

Just as he has stated usb 3.0 just separates the power and the data between 2 connections instead of over the same connection. That is why you can plug a micro usb into half of the charge port and it works fine.
As for a battery - I prefer slim style that fits in a pocket and I got the Motorola 4000mAh battery about 1-2 years ago on a dailydeal for $20. Built in micro usb cable + usb port means it can charge anything.

It is about the size of an iPhone 5 in thickness and size.

So you can only trickle charge without ASUS charger?

Just looking to confirm what I think I've deduced from the forum.
I can't charge my transformer when it's on or asleep with a standard USB charger, correct? I've invested in 2 different 2.0+ Amp 5V USB supplies and none seem to get the charge going on the Transformer. It sounds like I could turn OFF the unit and trickle charge it (by the way would the 2.0A charger be of any benefit in this circumstance?). It also sounds like the ASUS charger gives off 12V and that's what the Tranformer is expecting to get the charge going, right? If so, I'm definately dissappointed that ASUS went this approach- non-standard. I always like extra chargers for traveling and throughout the house and this has limited me. Anyway, if someone would be so kind as to reply to this and confirm I've read the threads correctly, I'd appreciate it.
The ASUS charger is 15V.
5V isnt nearly enough. If you got it powered OFF, you might be able to get it to full (from empty) in a few days (yes, days).
The TF can be charged normally with 10-15V.
I suggest you read this thread to get some other ideas.
Yea you need a 2 plus amp carger which also is 15 plus volts, and if you want to make your stock charge cable longer you have to use a male+female 3.0 usb cable... a 2.0 usb cant transfer enough power quick enouqh

So much misinformation in this post...
First... The real wall charger is 15v 1.2A. So the 2 amp is just bs...
Second... A usb 2.0 cable transfer power just as "quick" (wut?) as a usb 3.0.
The reason you need a 3.0 cable is because the charger is looking for connection on a pin only present on a usb 3.0 cable. If you dont use a usb 3.0 cable the wall charger will only send 5V.
This is done this way so you can use the wall charger for other devices apart from the TF.
You can open the charger up and bridge 2 connections to make it send 15v all the time. Then you can use a usb 2.0 cable just fine.
Please, try not to spread false information.

Before you correct people how about you do your research first.
Actually if you read the wall plug it is a 15v 2-1.2A. You can DIY a charger as long as it can produce 11v+ at 1.2A-2A and will trigger the charge functions within the tab. USB 3.0 is only required with the stock charger.
Dynex sold "The Ultimate Charger DX-UA" that had a MAX setting of 11v but when tested actually produced 11.7v at 1.7A. I was able to find one but they are rare now bc they haven't been making them for over a year now. It comes with aton of adapters one being a USB. I use it often without issue.
Also they sell on Ebay USB car charger adapters rated at 12v at 2.0A I own one of these also and it works great with the stock cable.

Actually I think youre the one who should read the text on the wall plug.
It clearly says "15v - 1.2A". the 2A is for 5v. Not 15. 5.

[Q] Can we charge directly the samsung player 5" with the laptop?

Hi
I have a laptop which working with 220V, can i charge directly the Samsung player(USA, 110V no ?) with the laptop with a usb cable ?
Thanks
yes

Quite simply, yes. Anything with a micro usb end connected to a power output will charge it.
Yes, regardless of the voltage at the outlet the computer is plugged into ALL USB ports run at 5 Volt (that is a USB STANDARD) so you can plug into the USB port and charge, the only reason it might not charge in a USB port is if the computer is REALLY old (pre USB 2.0) as the amperage of USB 1.1 is to low to be able to charge the player.
On a side note my 4.0 seems to last longer between charges when charged with the standard charger vs. charging thru the USB of the computer.
and if charge with the travel adapter, all i'll need is the cord that transports from american to moroccan ? or a transformer current too ?
(We have 220V)

Faster Charging 2amp Touchpad Charger for $4.99

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:

Is the usb cable that comes with it the same as the note takes?they don't show a pic of the other end and is it a charge only cable?If yes and yes I'm a gonna get one.Thanks

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.

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.

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).

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 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

Great price I bought 2!

1800mA Charging from a USB 3.0 port

I just hooked up my new Plugable 7 port USB 3.0 switch and although the speed is fine I noticed that the N3 still only charges at a lowly 450mA. Knowing that it should be capable of more, up to 4A in total, I decided to try a trick I'd been using for my Galaxy Tablets. These tablets won't normally charge from a non Samsung charger but with an inline dongle they will.
So I put the inline dongle between the switch and the USB 3.0 cable and presto, 1800mA charging current to my N3. Of course there is no data connection at that point but it's one less samsung adapter I need to keep around.
You can find the dongles here.

Umm dude use a normal charger oh i don't know the one it came with lol. I have no issue charging at 1800 mAh with standard charger. I understand you're using a port to connect other various devices but reason it's charging at that low rate is because it's USB and not seeing as AC. Just charge your phone in a wall socket and use your port for your other devices.

interestingly enough, it seems to only work on USB 3.0 ports
i have the cable version of that dongle you are using
on USB 2.0 ports still doesn't go over 1000 mAh, but it does double the usual rate of 450 mAh
cable quality seems to make a difference too

i did if you read my post you'd understand he did a trick to where it charges @ 1800mA in the usb 3.0 port which is essentially a wall socket. he uses a port for several devices, if he didnt care that he cant access usb then whats the point in wasting a space on a port and just use the wall socket.
What if you don't have a wall socket or forget to bring your AC adapter?

maybe you but the OP stated a 7 Port which means most likely it needs a power source i.e wall charger.
1. Even with an available wall power source, a USB Hub next to your keyboard is more convenient than the wall socket charger behind the computer.
2. A $5 adapter is cheaper than the original AC transformer.
3. You might not have the AC adapter with you when you're away from home but closer to another computer
4. A coin sized adapter is much easier to pack than an AC adapter
I'll be honest, I find myself in NUMEROUS situations where I have plenty of spare USB(3) ports but no spare wall plugs. My office is a prime example of this, from a 2-gang wall socket, we have 2x 8-socket extensions and those are all full. Some of those have another 4-gang extension coming from them, again full (mostly bloody adapters, so power draw isn't actually that higher - and yes we know it's a safety risk).
My computer, on the other hand, has something like 12 USB ports, of which about 8 are in use. Makes sense to me.
As someone pointed out the 7 port USB switch does have an AC adapter that provides 4A total. It's not that I don't have AC outlets at my desk, I have 10, but they're hidden behind a 400lb desk and not the easiest to get to whereas the USB switch sits within arms reach and is always on and available.
I also have several AC outlets around the house that have integrated USB charge ports. Given the number of devices that charge from USB these days these are very convenient but won't charge a Galaxy Tablet at all without the adapter. If you travel you will also find these at a lot of airports now too, usually located on the pillars in the waiting area.
In my experience at least it's a lot easier to find a spare USB port than an AC outlet, and that's assuming you have your charger with you. The adapter plug just helps you extract more charging current from what's available.

Differences in charging speed with "old" cable/connector vs. new

Couldn't find an answer to this after searching, so here's my question.
If I use, say the micro usb cable from the Note 2 to charge my Note 3, will it be as fast as using the Note 3's cable.
The note 3's cable is USB 3.0 which I understand would make data transfer faster (assuming PC has USB 3) but there's conflicting info about whether this makes charging faster.
For the sake of above, assume the power source is the same (i.e., a wall charger).
Does anyone know or has tested?
Cheers
Mine charges just as fast using normal USB 2 cable add it does the 3. USB 3 is higher data throughput. Not amperage. That is off the charger itself. I never use the 3.0 cable. I use 6ft USB 2 cables and still charge in about two hours, little less usually . It's all about the output on your charger. 2A like the stock one or Verizon ones and you are fine. 500mAh charger would take forever to charge it though.

I actually notice a difference or I'm not sure if it's in my mind but a hour and my battery is fully charged with supplied charger my old note 2 charger take 1.5 or so hours to charge.

Now I'm not sure about subtle details on how usb charging works, but it seems the original wall adapter is not outfitted with a usb 3.0 port. If you look at usb 3.0 ports (female end) they have metal contacts on the front edge, which the samsung wall adapter doesn't have. Not sure if the extra contacts carry current, but my guess is if only the standard usb 2.0 contacts are being used then speeds would be equal regardless if a 3.0 or 2.0 cord is used.
I have USB 2.0 cables that charge just as fast as the supplied USB 3.0 one. I also have ones that don't.
Don't buy really cheap cables. cheap ones usually have thinner copper wires (the cable could still be thick, but that's down to thicker insulation). If there's not enough copper to allow the current to pass, the charge rate will be slower.
I believe the USB 3.0 cable only charges faster if plugged into a USB 3.0 port on a computer compared to a USB 2.0 cable. On a wall charger they are the same speed.
Wish there was an app like Galaxy Charging Current that would work on this device.

USB 3.0 spec shows 900mA so I suspect that connecting to a USB 3.0 port on a computer isn't going to charge as fast as the 2A wall charger over either USB 2.0 or 3.0 cable. The big difference should be in data transfer. I never charge my Note 3 over USB 3.0 cable, always the 2.0 cables that I have all over the place. Strange thing is that it charges consistently faster than my Galaxy Nexus on the same cable/charger.

Galaxy charging current lite works fine for me. The cable makes no difference at all. Good quality cables should charge at 1800mA from the charger regardless of whether they are USB 2.0 or 3.0. This translates to a little over 2 hours charge time.
From a USB port either cable will only see 450mA unless you insert an inline adapter designed to make the note think it is connected to a Galaxy charger.

Just uninstalled and -reinstalled the app, now it's working. coo
How is the current for charging detected?
Differenc in charging time depends on a higher charging current.
The current of 500 mA for USB 2.0 and 900 mA USB 3.0 to my knowledge only for the Device = Note supplying power to external Devices like USB-Sticks (e.g. Memory or DVB-T), Hardrives and so on. It does not specify in regard to using a USB plug as charger nor the the current it charges the notes with. I am wondering how the current detection between the original Galaxy or Nexus charger and any other charger, USB-Hub or computer port is done.
When you compare µUSB-B 2.0 to 3.0 connection http://en.wikipedia.org/wiki/USB_2.0#2.0 and here http://en.wikipedia.org/wiki/USB_3.0 youls find that the USB 2.0 µUSB-B has the same connection as the µUSB-B 2.0 (note http://en.wikipedia.org/wiki/USB_3.0identifies 11 Pins for µUSB-B which seems incorrect because Pin 5 has to be ground to be backwards compatible).
The additional 5 Pins are only for the 4 USB 3.0 Data-Lines and ground.
If you look into the USB-A connector in the charger you'll see also only 4 Pins like in any other female USB-A 2.0 connector, so using a µUSB-B 3.0 can't be the reason.
I'll edit this as I have more things to test. All using Galaxy Charging Current Lite app
Charging current:
OEM USB 3.0 cable + wall charger = 1200
OEM USB 3.0 cable on PC USB 2.0 port = 450
Monoprice USB 2.0 cable + OEM samsung wall charger = 1200
Monoprice USB 2.0 cable on PC USB 2.0 port = 450
Mine charges faster with the stock USB 3.0 cable. This is incredibly fast compared to the Note 2 charging cycle.

OK here are myvalues Charging Current Lite app displayed charging current:
Samsung USB 3.0 cable with
Samsung wall charger = 1200
USB 3.0 10 port Hub-charging port = 1200
USB 3.0 10 port Hub = 450
USB 3.0 Elitebook 8560 = 450
USB 3.0 Cable with USB-A 3.0 to µUSB-B Adaper = 1200
So it's not the cable that makes the difference.

I'm getting similar results.
USB2.0 cables same as USB3.0 cables as far as charging goes.
Also regardless of plugging into USB3.0 port or USB 2.0 port on computer, still pulling only 450.
Using OEM samsung 3.0 cable, and amazon 3.0 cable.
OEM samsung 2.0 cable, monoprice 2.0 cable.
Oh, and it will charge at 1800 using both a USB 2.0 and 3.0 if the screen is off (turn screen off, plug charger in, turn screen on open galaxy charging current lite and it will display 1800 until refreshed).
I had the time to check the AC consumption of both the Note 2 and Note 3 PS, both are with the Note off ~11 W independent of cable used.
When the battery was fully charged at 100% and the power consumption was arround 6 W, I started the Current Lite app and it displayed a charging current of 1200 mAh even so the battery was charged? Something is wrong with the displayed value if the battery is fully charged, unless it's supposed to be only the current supplied to the Note. Then why does it not correlate to the AC-power meassured?
I looked at the voltage of the Note 3 PS and noted it's 5.3V while the Note 2 PS is the standard 5 V.
If I find time i will built an adapter and check if the voltage is true DC or if there is some other signal imposed.
Or do the Notes PS initiate some kind of data transfer to let the Notes know its the original charger that can supply higher current.
Any ideas or input.
Isn't snapdragon 800 on the note 3 suppose to have some sort of quick charging feature, that when used with the factory cables should increase charging speeds?
I could detect at best a few 100 Mw difference difference between charging with the OEM cable and any other USB 2.0 or 3.0 cable with µUSB adapter or when I used an adapter to µUSB.
Car Charger
Sorry, but I can't seem to find the right answer.
I need to charge my phone whilst being used in my aircraft.
Using a USB 2.0 cable on the Note 3 supplied charger, I only get 450mA.
Will it charge faster if I install a 2A car charger in my aircraft and use a USB 3.0 Note 3 cable?
Regards,
Erich
I use a 2 Amp charger in my spaceship and it can be used to monitor the ecu while still providing enough power for the phone to charge.
You just need to be sure that the charger actually deliver 2 Amp and not 500mah
