[Q] unable to charge through pc

can i check with all bros using eee transformer is it possible to charge transformer through PC as i plug it in for more than 8 hours and it is still 60% but it went up when i put it to the asus usb adaptor to charge and if i were to use other commercial usb adaptor, it doesn;t charge again.
kindly advise. appriciate all input.

tf needs 15 volts, standard usb only provides 5 volts, hence no charge

bro trosenda, so i cannot charge through my pc?
what about commercial usb charger?
i thought they supply 15v also?
finally, is there a way to charge through PC?

I have my wifi policy set to sleep and my pc will charge my transformer, however it is very slow.
For a quick charge you need mains

bro straxusii, for main i have to use the usb adaptor that they supply? or any usb adaptor will do?

If you take a closer look inside the USB cable or adapter you'll see a set of extra pins behind the standard 4 USB pins. I presume these are used for charging the TF @15V. USB chargers output 5V.

The transformer does technically charge on any usb but only when the screen is off and even then at an extremely slow rate. With the screen on it wont even bother because the drain far exceeds the charge. 5v @ 1A max for your standard usb, 500mA on most laptop or pc usb ports, vs the transformer's native 15v @ 1.2A.
For main you will have to use the provided charger, its the most annoying part of the transformer right now.

this part i gotta agree with you bro. maybe in future they will come out with a usb charger which is capable of switching between 5v to 15v as and when we need. or just a usb charger for all sorts of things. maybe a 25v charger haha... might make things like iphone charge faster.

[Q] does the N10 have separate micro USB and charging port?

Does it charge with Micro USB? Or is there separate charger that would allow for simultaneous OTG & charging? If so, is it a samsung proprietary cable?

one port. I don't see why people are all upset with a tablet having one micro-USB port? What I would do to have micro USB on my Asus transformer prime, so damn annoying!
ANd plugging into a PC will charge slowly for most phones, and it depends on tablets, some do some don't. Even then, who leaves their tablet plugged into their PC all day anyways, a big no-no for phones as we all already know, won't charge very quickly...

Are the pogo pins not for charging?

They can charge as well when the tablet is in a dock (if that ever happens...). The pogo pins are not the primary charging method when not in a dock.

ah.. well for one thing, I would say the primary reason is the one I just stated: simultaneous OTG + charging.
There are users out there that do not like the limitation of having no MicroSD card.. The closest thing, without microSD, is OTG. But the problem is that you cannot constantly use it or the battery will empty [also using battery cycles, that could have otherwise been avoided, and saved for when you really need them].
So may I ask where you got this conclusion? I would like to show it to someone.

Would a usb splitter work if you wanted the device to have two ports? Just a thought.

No, you'd be trying to charge the device, while it is giving out power on the same wires, to the USB OTG device.
The only way to fix it is with a kernel patch to disable outgoing power, and accept a charge with OTG.

Can't you buy an charger that fits the pogo pins. Not from google, of course.

maybe..but on the Nexus 7, when you plugged in OTG storage, it would not charge with the pogo pins--at least I'm pretty sure I read this on xda.
so it might be like this on the Nexus 10 too, I dunno.. I guess we'll find out soon.

I was referring to charging/microUSB ports, had nothing to do with MicroSD card slots

No, I meant, you asked why people were upset it just had one micro usb port [instead of--I assume--a charging port, and then an additional micro usb], and I said it is [at least for me] because it makes it harder to properly use external storage [that's needed for some people because of the lack of micro sd].
is there an official spec sheet that shows it charges via its only micro usb port?

Hi everyone, I was wondering what type of micro usb port was on the Nexus 10, I cant seem to find any close up photos, I am a noob when it comes to tablet and smartphones, but after looking around for OTG cables and such for my futur N10, I came accros micro usb type A which is bigger and thicker, and micro usb type B which is nice and thin, so I'm kind of confused, which type do I need for N10, can anyone fill me in?
Sorry if I posted this in the wrong thread, but it would probably of been silly to start one for such an easy question . ^^

Yes, via a normal charger adapter. The USB cable is pluggable to the charger.

Sorry, but then buy a tablet that has a MicroSD. The Nexus series doesn't have MicroSD. If you don't like that, there are other options.

Difference in charging speed with different chargers?

Hi,
I was wondering if using a 2A charger with a normal Micro USB cable will charge my Note 3 as fast as the same charger with a Micro USB 3.0 cable?
Considering that USB 3.0 only delivers a higher output compared to 2.0 when plugged into a PC, I guess it makes no difference when using wall chargers?
Am I right ?
Thanks in advance,
Ben

USB from a PC will always be less than a dedicated charger whether it is usb 2 or 3. A 2 amp charger is what I use but also pay attention to the lead as some are far better at handling higher currents than others as I found out trying various leads whilst running the app at https://play.google.com/store/apps...=organic&utm_term=galaxy+charging+current+apk

The phone detects if you are using a wall or usb charger, the second is considerably slower. Some usb chargers cheat to seem wall chargers so charges much faster.

What if I use a micro USB cable that is attached to a wall adapter plug, will it still charge fast on note 3?

Charging is not depend on USB 3.0 or 2.0, it acts differently only while transferring data. Otehrwise for charging both works similar.
The stock wall adapter has 2Amp output and I’ve a power bank with same output and the Power Bank provided with a short USB 2.0 cable and with both it takes same time to full charge. So no issues with the cable.

USB 3.0 and Wall wart

All of my previous phones' chargers have been like 1A and usb 2.0. The note 3 quite obviously differs in both of those respects. Now, I know that I can charge my note 3 using all my old chargers no problem, even if it's a little slow. But, I've got two questions.
1. Does the usb 3.0 allow more current to the phone or just faster data transfer? i.e. Am I losing anything by using the note 3 wall wart with a usb 2.0 cable?
2. If a usb 2.0 will still deliver the same amperage: Say I left the 2A charger with a usb 2.0 lying around and someone with a less powerhungery phone comes along and plugs in, will that damage their device?
Any help is much appreciated.

1. USB 2.0 and 3.0 charge the same. The extra pins are only for data.
2. No problem. Devices only pull as much current as they need.

[Q] What's the USB 3.0 for?

Hey all,
I was just wondering, what's the USB 3.0 for? I mean, the micro SD card isn't fast enough to max out usb 2.0 transfer speeds, and the internal space is capped by the MTP system, right?
Thanks in advanced.

I believe sammy made internal sd cappable of transfering real quick, I tested it with my 32gb dunno wat was it called, but its supposed to be fast, like real fast...so 3.0 is from cellphone to computer, If yours support it, it will be the same as int storage to ext microsd(if it supports fast transfers)

I don`t think the USB 3.0 is useful at all the Class 10 SD Cards has a write speed of 40 MB/s USB 2.0 is 60 MB/s so yes the SD card couldn`t even match the USB 2.0 Spec and internal storage is only 16 GB so even if it`s capable of reaching USB 3.0 speeds which I highly doubt as the USB 3.0 speeds are really close to the SATA 3.0 Specs and currently there is no hard disk on the world matching the SATA 3.0 Specs so I doubt that the internal storage is capable of reaching USB 3.0 so yes the USB 3.0 is not useful probably the only reason we have it is because it charge the phone faster then a USB 2.0 cable because of the additional pins.

I think they went with usb 3.0 with the sole purpose of increasing charging rate, the batteries are starting to increase in size but the rate they charge hasn't really changed much so they went with usb 3.0 to increase the rate. Quickcharge 2.0 is coming soon though so that should help to

usb chargers are NOT usb 3, they don't have the extra back row of pins needed, they only use the standard 4 pin usb which is usb 2. if you use a charging program like galaxy charging current you get no improvement with usb2 over usb3. most s5's were only shipped with usb2 cables anyway. quick charge 2.0 is based on standard usb2.

yeah i dont see any speed difference tbh

Yes if you charge from Laptop but what if you use the charger ? Since i have both usb 3 and usb 2 cables I will test to see if there is a difference in the charging time.

Can you please test and let us know whether usb 3.0 cable charges faster or not
