[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.

Quick Charge 2.0/Adaptive fast charge - cable & charger specs ?

Hello all
I'm trying to understand the actual meaning behind the the Quick Charge 2.0
Let's start with the cable:
The only parameter is the AWG ( as I read the recommendtions are for 3 feet (1 meter) is 24/28 wire gauge) ?
There is no special chip or support by the cable (as apple has the MFI for their cables)?
I had good experience the original LG cable (the one that comes with G2,G3,G4) , and Nillkin Cable Universal Flat Micro USB .
Other recommends are for Monoprice cables...
Any other good recommendations ?
What is the recommend AWG for 6 feet? any good cables you know?
Let's go to the charger:
Does it's really matter if the charger marked as "quick charge 2.0" certification ?
Did you get quick charge 2.0 results with charger that is not marked as quick charge 2.0, just by using charger that (really) outputs 2.1A ?
What is specs for a good charger ?
I know it's a lot of questions, but I know that you are kind
Thanks!!

Anyone?

[Review 11/22] Ravpower 20100mah Type-C/QC2.0 External Battery Pack

Ravpower 20100mah Type-C & QC 2.0 Battery Pack
Overview: The Ravpower battery pack is supposedly the first USB Type-C battery pack out there. It charges the 6P using the USB Type-C standard of 5V/3A which is great because it’s the first true Type-C charger and battery out there not made by Google from what I have seen. I will compare the battery to the other ones I own which are just the regular QC2.0 standard and made by Aukey.
Ports/Charging:
The Ravpower features 4 total ports, now before you get carried away with the infinite possibilities of this I will first talk about what they offer.
Ports Comparison
Input Charging Ports:
There are 2 ports that can be used to charge the battery. The first is the conventional Micro-USB port. This port will allow you to have the battery with up to 24W, and is a good backup if you don’t want to charge it via USB Type-C. The next way the battery can be charged is via USB Type-C at 5V/3A (15W) which is slower than using a QC2.0 24W+ charger. I know there aren’t many 24W capable QC2.0 chargers but I have a 30W one made by Power Partners and it charges the battery a lot faster than my Type-C cable does.
Here is breakdown of the voltages/rates the battery can be charged at:
Output Charging Ports:
Type-C
The battery can charge up to 3 devices at once with its 3 output charging ports. The first and most relevant of these would be the USB Type-C port. It will charge the Nexus 6P/5X rapidly just as the wall charger would. I’ve had the battery for about 3 days now and it has been great! The USB Type-C port is reversible in terms of charging for this battery pack. The port can take 5V/3A and output the same 5V/3A to a phone so it cuts down on how many ports the battery needs.
USB Type-A QC2.0
This port features Qualcomm’s quick charge 2.0 standard and will quick charge any compatible devices at one of 3 voltages. The port can also charge the Nexus 6P/5X using a in spec Type-A to Type-C cable as you might expect. I have the iOrange cable and it will give me 1.5A as it should by the USB standard. I like the availability of a Type-A port because I can charge other devices from it while on the go.
USB Type-A iSmart Port
This is your standard 5V 2.4A USB Type-A port. There is nothing special about it in my opinion and they could have left this one out since the QC2.0 port also supports 5V/2.4A. It’s still there if you wanted to use it so I will leave it at that.
Here is a table of the output voltage and rates:
Battery I/O Rating Pictures
Design/Build Quality:
The design of the battery is nothing special, it’s a simple rectangle just like it should be. There is no reason to over design the appearance of an external battery as long as it gets the job done. I don’t mean this in a bad way at all because I like the simple design of it. There are 4 blue LED dots that indicate the battery level and they aren’t overly bright if you use it at night. There is a small button under the LED lights to turn the battery pack on or see its current battery level.
Let me get this out of the way: the battery is HUGE and might as well be a brick making up some old building in Philadelphia. With that being said the battery is solid but not too heavy overall. The battery is made with a plastic construction, but Ravpower does offer a 12 month warranty on it. I didn’t look to see what it covered, but I assume it should cover the standard defects but likely not physical damage. According to Ravpower these are the dimensions of the battery pack:
Here is a comparison between the 3 battery packs I currently have. (Aukey 10000mah Silver, Aukey 12000mah Black, Ravpower 20100mah Black)
Status Lights for each battery pack
What’s in the Box:
The battery comes with a mesh pouch to put it in while you are traveling about, but it has no extra pockets for anything else. There are also 2 micro USB cables included with the battery that can be used to charge the battery or a compatible phone. The flat style cables are nice and should be tangle free. I used one to charge my Bose QC20 (2015) headphones and didn’t have any issues. I would test them on another device, but I no longer have micro USB phones/tablets.
Dimensions
Overall 9.8/10
I’m enjoying the battery pack a lot and I think it’s worth the price right now. $47.99 isn’t bad for a 20100mah battery considering I have 2 Aukey ones (12500mah, 10400mah QC2.0 battery packs). The battery is big, but it has more than enough capacity to keep your phone/tablet alive for a few days at a minimum.
Here is a table comparing the Ravpower to the Google 22.5W Dual port Type C charger with different cables, I also tested my in spec Type A-C Cable using a 5V/4A charger

So I would still need to get another C to C cable to charge my phone quickly, or use the included A to C at a lower speed?

You cna use the C-C cable that comes with your phone to rapid charge your phone. Any USB A-C cables are limited to 1.5A by design so it won't rapid charge with a Type A that is inspec. Out of spec ones might but its not worth the risk

Right, I just meant that if I wanted to keep this in my work bag or in my car, I would need another C to C cable, because the one that came with my phone would stay at home with the charger. Thanks for the review, I added it to my Amazon Wish List.

Yes you need a C-C cable to rapid charge at the 5V/3A but you can charge slower with a Type-A to Type-C which will give you 5V/1.5A. The monoprice C-C USB 2.0 cable is inspec according to Benson so I would get that one. It's ~$13 I believe.

No their 3ft USB 2.0 spec one was that much unless I'm thinking of another company.

I have this same charger. 70% off my town has been with out power for the past 3 days (including my house) and this thing saved me a few times already. I can fully charge my phone almost 6 times on 1 charge. It may be big but it charges fast and many times. I dig it

Just bought one today via Amazon with same day shipping! Question - can I charge my phone via USB A-C cable and simultaneously charge the battery with the C-C cable?

I haven't tried but it might work. I know most batteries support I/O at the same time.

I've used it to charge my phone for the past 3 days just to test it. If has 2 dots left (~50% or less) which is good. The battery may but be metal or asthetically great but it gets the job done

[Review] CHOETECH USB A-C Cable with Current Voltage Monitor (3.3ft/1m)

I recently received a CHOETECH USB A-C Cable with Current Voltage Monitor for review and I have got to say its come in really handy so far.
I've always wondered just how much current I was getting from my many chargers that all claimed to be up to 2.4A. I know from there various different charge times that they weren't all providing what they marketed at. This tool has come in really handy for helping me weed out the good chargers from the bad.
Before anyone comments that this cable wont allow my nexus 6p to charge at the 3A that it is capable of I know this already, but this cable has allowed me to test me standard USB-A port powerbanks and car chargers that I still use with USB A-C cables. I know USB-C equivalents are available but I don't see the point in replacing my old chargers for the benefit of 600mA.
The CHOETECH cable comes in a nicely presented package that gives basic info about the product.
The cable is neatly coiled up using rubber bands to keep it safe in transit and the instructions that come with it are both clear and concise.
Using that cable is as easy as just plugging it in and it works straight away, alternating between voltage and current.
I found this cable to be alot more accurate than apps that I have tried to use in the past giving me results that I would expect to see from the charging device I was using.
Usings a mains adapter gave me the best charging current while a cheap nasty car charger gave me very poor current but I suspected this from my charge times. Apps I had used in the past gave me very unreliable results so I am glad I've bow got this cable.
I'll definitely get my use out of this.
On a side note, even without the volt/ammeter this is still a very good quality charging cable and it doesn't interfere with data transfers. I would definitely recommend to anyone interested.

If anyone in the UK is interested in one if these cables or the Micro USB equivalent I've got some discount codes that reduce the price down to £6 which is a bargain for these cables.

Great stuff, thanks for the post faybarn. I just bought one of their USB-A to USB-C cables (without current / voltage monitor though).

is there any other options on this that's available to ebay or aliexpress???

Cable that truly fast charges from 0% to 100% at 78min?

Hello
I need to replace the usb cable that connects to the original charger that comes along with the phone.
There are cables out there that are sold as original Samsung cables but don't fast charge the phone in 78 minutes from 0% to 100% even if they are connected to the original charger.
So is there a cable that truly fast charges the phone exactly like the original in 78 minutes?

The cable has nothing to do with it. Use a regular functioning USB cable with a Quick Charge 3.0 charger (such as the Samsung charger with the lightning bolt on it, or the Anker Quick Charge series) and the phone negotiates with the charger. The cable is just a medium. I prefer the Anker PowerLine+ cables for their durability; the stock Samsung cables are fragile.

Τhanks a lot socal87. I was thinking the same thing as you but i got worried from negatives reviews in amazon ( saying that the cable they bought wasn't fast charging the phone).
Also in another well known forum, there were comments like the following :
"Samsung plays with the extra pins on the microUSB connector to tell the phone different things - like USB/AC charge, or fast/normal charge."
"My troubleshooting with 7 different cables showed me that the the very new Samsung charger cables that came with non-fast-charging phones did not fast charge when connected to the fast charger adapter portion. It appears that the cable does in fact matter. I tried many combinations of cables and adapters during my testing."
I will buy an Anker cable as you suggested. In another forum i read than indeed the Anker cables do the job right with fast charging. Thanks again.

Of course the cable has to do with the charging of the phone, try charging with a cheap $2 cable from eBay and try yourself.
Best cables (that i use) are from Monoprice, get their Ferrite core one, best cable out there, charges my phone to 90% in around 70-80 minutes with normal charging (no Fast Charging)

Try any original cable from HTC Nokia Samsung Motorola you can find one in repair place ask him for used original one or new...

Τhank you all for your suggestions. I have already ordered an Anker powerline cable from Amazon and i face any problem i ll buy one of those you suggested.

Blitzwolf does be more better distance charge of 1m at Maximum average 2,1-2,4A of 9V/2A or 5V/3A

You can find Samsung original cable in any official service. I have paid 5$ for a 2m long cable and it takes about 1.h20m to charge from 1%
