[Q] TF Charging Indicator?

Sorry if this has already been asked and answered - the XDA Search has been down for the past couple of hours and I just want to be sure I'm not missing anything here..
From what I can see in the reviews, the TF does *not* have any sort of charging indicator / LED on it - correct? I read that there will be one on the keyboard dock - but there is not one on the tablet.
So what are you guys doing? Just plugging it in and letting it sit overnight to give it its full charge - and then going by the battery indicator when you turn it on?
I've got my new TF sitting next to me here, and I'm trying to be a good dad to it by charging it up first before using it - but not having any sort of an indicator on it - I have no idea if it's doing anything or not!!!
Screw it - I think I"m gonna unplug it and start futzing it with it! Battery be damned!!
btw - damn this charge cable is SHORT!!

No charging LED that I can see on mine, and yea, I hate this stupid charging cable, guess you can always get a USB extension cable.

Monoprice has the USB 3.0 extension cables, but they won't be in stock until tomorrow (their estimate). When they are back in stock, a 6ft extension will run you about $7-$8 shipped.

I plan to order a few cables from Monoprice with a mini hdmi to hdmi cable.

Does it need to be usb 3.0 or will usb 2.0 do the trick ?

USB 2 cables don't supply enough power.
It will charge, but I think it has to be off and it'd be really slow going.

But usb 2.0 extension cable will work fine with the supplied charger? Also would you not require a usb 2.0 to usb 3.0 converter ?

Asus really overlook the inclusion of an charging indicator. Or, they are trying to make more $$$ on the keyboard/dock?

Has anyone got some definitve experience on USB2 vs USB3 for charging and/or with an extension cable. The whole charging process and adaptor are making me a little nervous in general.

there is no reason to invest in USB 3 gear when all you really need is higher amperage, wich you often get from stand-alone chargers like the one supplied or you can buy in stores (just check that the output is 1000mah or more, 2000 mah is desired for effective charging).
The reason you might want to use a usb 3 PORT (cable makes no diffrence) is that usb 3 deliver more juice then usb 2, but unless it is a dedicated charger port that can supply 2000mah+ charge the port still require you to have the pad either off or stand by and even then charging will take ages.
Consider this, the supplied charger delivers 2000mah on 5v and my HTC charger to my phone has 1000mah @ 5v. Compared to the standard 550mah on a singel non-charger adapted USB port on a computer.

The TF charger output at 15V @ 1.2A with using the supplied USB3.0 cable. If you use a USB2.0 extension cable, it will drop the charging voltage down to 5V. You will need a USB3.0 extension cable

There's a thread about this issue here. Several USB 3.0 cables have been found to work, but not for everyone. I have this one that I received today. It charged both the tab and the dock with the wall charger. I've also got a Tripp Lite that's worked for others on the way in the case the other didn't work.

it has to be USB 3.0 extension since the tablet recognizes the extra pin which is what lets it charge at the full rate.

Not quite correct. The charger senses a gnd connection on pin 7 of the USB 3.0 connector and delivers 15V @2a to the TF and or Dock. There are only 4 conductors in a USB 2.0 Cable. so the charger only delivers 5V as it does not see the gnd on pin 7. For all the technical details see the thread started by DevCake where the voltages and currents have actually been measured. A 5V 20A charger will not be as good as one with 11-15V at about 2A as the charger is not a constant current charger but a power source for a charge controller ( controlling the current) in the TF.

I appreciate that it is a slightly older thread and not sure if what I'm about to post is already known by TF owners but here goes anyway.
The discussion has moved on to cables but the threqad title is about a charging indicator. I've discovered that the battery icon in the bottom RH corner has a lightning symbol through it when it is being charged.
Sorry if it's old news but I've only had my TF one week and thought other users might not be aware

Really wish they would have put in a fancy multicolor LED somewhere on the housing but we can't win them all. Even the Nook Color had an LED on the cable itself.

Charging Cables

Do the TF200/Prime/Other cables word with the Infinity?
I'm thinking about just getting a couple of spare cables here: http://www.amazon.com/gp/product/B007GJR7GS/ref=ox_sc_act_title_1?ie=UTF8&smid=A1HKVQTYI2W24Y but want to make sure that they fit and work.
Also, (perhaps a separate thread?) Can we use any AC to USB converter (and cable) to charge the Infinity? The adapter bundled with mine was a bit more robust than normal adapters so I'm inclined to think no, but wanted to confirm before I get a spare one.

My cable from my prime works with the infinity....I also tried a cigarette to USB plug in my Jeep and it would not charge the Infinity

if anyone finds out if other USB charging adapters work successfully, could you please post about it?
much thanks

None of them will work. The charging cable for the TF700 doesn't use any the USB pins for charging. It has additional USB3-style pins hidden up inside the connector. Also, the stock charger outputs 15V which I doubt we'd find on any standard USB charger.

Actually, correcting my previous post, it can charge via a USB 2.0 connection (as on a standard USB charger) but very very slowly. The current is not enough to charge it while the screen is on. The display will read, "Not Charging" but it actually does. See the following thread for more info:

Umm... did you actually test that? I went through my charger pin by pin with a multi-meter and found 5 VDC between pins 1 and 4. Look closely at the charger, it says it can supply 5VDC @ 2A or 15VDC @ 1.2 A. The only reason for switching to 15VDC would be if they had some sort of feedback signal on pins 2 and 3 going to the plug-in adapter to signal that the battery was fully charged and tell it to switch to a higher voltage/lower current mode.

ASUS standard charging cable has 5 pins instead of 4. I'm betting the feedback you're looking for actually occurs on the 5th pin.

Nexus 4 car charger??

Hi
Im searching for a car charger for the nexus 4 that will charge the device even on navigation running...I now that the Motorola Rapid car charger was good with the galaxy nexus.I dont know if itS ok with the nexus 4 because on the LG charger it sayS 1.2A?I read that the Bracketron Universal Dual USB Car Adapte 2.1A will just work as AC charger if plugged in with a USB charging only cable...but i cant find those cable to order online here i Canada...and i dont wanna do it myself and modify a regular usb cable ...Soo if someone can help me it would be much appreciated.

You dont have to have a modded cable if your car charger already has the data pins shorted. Im using the motorola rapid charger too and it works fine, it will charge your phone as AC and give enough power to recharge the battery with navigation on. if you want something a bit better you can try this one , they ship to canada. My rapid charger broke so i bought it a few days ago. Reviews says the trident will give around 8-900mA, the moto charger outputs around 6-700mA.

I would only buy a premium brand here. If you see how no name mains adaptors are made... the risk of blowing up something expensive is just too big.
I wnent with the Sony AN-400 / 401, because it is rated at 1.2 amps exactly, is small, and was reported to work fine.
For some regulator disasters:
http://hackaday.com/2012/08/15/buying-cheaper-electronics-and-not-saving-money/ <- a USB car charger without components, putting 12 volts straight on USB.
http://www.youtube.com/watch?v=wi-b9k-0KfE <- teardown of imitation apple mains adapter, showing no output protection and very little gap between mains voltage and output circuit. Good info, but style of presentation is not my cup of tea.
So that is why I went with a premium brand.

that's one charger from one factory that some guy that didnt know what he was doing and ordered thousands, without testing them. He probably went for the 25 cent super deluxe model...
Well reviewed chargers from xda members here and not to mention the hundreds of people on amazon are a safe bet. Here's a 8+page thread on the charger i linked. Your premium brand name sony charger is made in china too.

That looks ok,but I cant find a good quality usb charge only cable that ships to canada :

I have a el cheapo usb charger from ebay and I used my usb cable that came with the phone...and when i pluged it in it switches from AC charge to USB ever couple of seconds back and forth...so I want to try something different.

If you're into rooting and custom kernels, most of them have a fastcharge option where you don't need to have a special usb cable, or, attempt to short the D- and D+ lines.
Monoprice has a 2.1A bullet charger for a bit cheaper:

i cant say for sure until i get it sometime next week but i think so. im in canada too and couldnt find the powergen anywhere that would ship here.
There are some other brands that are good too but i like this one cause it's dual usb like my old moto rapid charger. If you dont need that you can get some smaller ones that will work just make sure they are well review and can output around 1A. The one that bfspider spider recommends is a good bet too since monoprice is pretty reputable store and will ship to canada.

You can try to mod this one in the mean time, just take it apart and attach the two data pins(they are the two middle ones). Solder is best but if you cant you can just use pilers and bend the pins until they touch. i did this with a few of my chargers too and it works to make them AC but it wont increase the output if its low to begin with.

FYI, this adapter should allow most existing "iPad" chargers (1.2A or higher) + any USB cable to work well with the Nexus 4.
The problem is that Apple products deviate from USB charging standards. As a result, most chargers try to be compatible with iDevices and also deviate from the standards. So when standard-compliant devices try to follow the standards, the chargers refuse to follow the standards, and the devices get upset with each other. Fortunately, they fall back and settle on a lower-power charging rate.
If you want to buy chargers that are very clear on what they support, check out MediaBridge (also available on Amazon).

So i got that Trident charger that you recommended....the quality looks good...but when I tried it in the 1A and 2A port with the usb cable that comes with it,it shows USB charging but when I use the HTC usb cable that came with my HTC one S it shows AC charging....its so confusing and I just dont get it....that HTC cable is a sync and charge cable.

The generic T-Mobile car charger available at T-Mobile stores charges just fine. I believe it is at least 1 amp. Its black, has a purple white small led indicator when charging. The USB end looks like a little block and the cord is an accordion type and it also has a a female USB slot in it to plug something else in at the same time but I believe whatever USB cord you plug in there only charges at .5 amp. With this charger I can run navigation and Bluetooth and Pandora and message at the same time and it will charge.
Sent from my often RMA'd Nexus 4, So that I can use the one I'm using now when I get the 6th and hopefully final one.

I just dont get it why does it with one cable show USB charging and with the other HTC cable AC charging?:S

[Q] TF700T charged on a wall socket using this...

Hi everyone... I have an asus tf700t and I was wondering if I can charge it using the belkin mini surge protector with usb charger ( w**.belkin.com/us/p/P-BZ103050-TVL )? I just wanna make sure if it would be ok plugging the usb cord straight to the usb socket of this belkin usb socket. I carry a lot of gadgets with me whereever I go so I kinda feel that it would be bulky carryng a lot of chargers for my cellphone, laptop... etc. Would this be safe? I just experienced last week someone's charger got toasted using a public wall socket using the original charger. Thats why I thought of buying a surge protector as well. Thank you.

Depends on what you mean. Do you mean skip the Asus wall plug and use the usb ports on this protector? Then the answer is no. The usb ports on any device you use to charge the tablet needs to be usb 3.0 and supply the needed 15v of power. All of the usb plugs that are sold are made for 2-5v devices. If there is one that does supply the 15v then I have not seen it and many people using this forum would probably love to purchase it. You've stated one main reason to buy something like this, limiting the number of plugs to carry around, but it's also like $40 bucks to buy another plug from Asus.
That 2-5v is enough to charge cell phones, gps units, apple products, other tablets that don't use a proprietary power plug, etc. It may supply a small trickle of power similar to hooking up the device to a computer while the tablet is powered off. That would take hours to charge the device and not what you are looking for. I think one of the advantages Asus went for in using usb 3.0 and 15v is the speed of which the device can charge. It is pulling more power and able to delivery it to the battery faster. That is my guess but it is limiting our after market choices.
Now if you mean use that as added protection and have the Asus plug plugged into it, then yes it will work. If you are concerned about pulling too much power through it then don't have the device hooked up to it and use all of the other ports on the protector at the same time. That little device does seem neat. I lost an a/c adapter for my laptop when lightening struck really close to my hotel. Fried the power brick but luckily the laptop was not damaged. At work and at home I use a power strip/surge protector when plugging in the tablet to charge.

Ok tnx for the input. Just wanted to be sure if it would not harm the device if I use the usb wire without the charger adapter that came with asus but rather plug the usb cable directly to the belkin usb socket. Being stated that the tf700t is usb 3 and 15v is needed, will the belkin suffice to charge the device using its usb slot for charging without causing any harm? The spec says in belkin mini surge protector is 5V/500mA each usb port.

It should work and do no harm, but it will be very very slow - maybe 5% per hour...

It's a USB 3 plug, and the additional lines are somehow used by the Asus charger for detecting the tablet and switching the voltage.

[Q][A510]USB charging- possible or not?

Hi
I'm wandering if it's possible to mod my a510 to allow USB charging:
-according to teardown picture it's a standard 3.7V one (looks like 2 cells in parallel)
-charger is rated 12V but output is connected to extra pins- there are 2 rows of pins, one is USB and second one I guess is used by a dock
Except for making us use official charger I can't see any reason why USB charging is not present.
Do you know if it's possible to get a510/511 internal schematics?

This plus USB cable works.
I've also tested the standard data transfer USB cable connected to the PC.
Try it, leave it charging overnight connected to your PC.

A normal USB-cable will be enough... It'S only very slow

I'm wandering if it's possible to mod my a510 to allow USB charging:

Until yesterday I'd have said you "no" but this night I have changed my mind.
On another forum I've read of a user that succeeded in charging the A510 via USB even if slowly (2%/hour) and if the screen is off.
I've tried many times with some 5V 1.2A USB chargers with no luck
My girlfriend yesterday gave me as a present a Anker Astro3 12000mAh battery-operated USB charger with 2.4A output and it charged my A510 from 77% to 100% in about 4-5 hours.
So, it seems it's possible to charge the A510 with USB, if you have a powerful enough charger and enough time.
