I just bought two sets of SONICable,The World's Most Advanced Charging Cable, for $49.00. Supposedly, they will increase you charging speed by 2x. It's a crowdfund project, and the cables will supposedly be delivered in March 2015.
I'm not affiliated with the project. I only think it sounds like an exciting product and decided informing the community about it.
Does it work on the same principle as this video for doubling your WiFi speed?
Code:

Well while surely there are better and worse cables, doesn't charging speed depends on the output of the wall piece and the charging circuitry?
On bad cables i get at most 1 Amp to charge the tablet, but with the original samsung cable i do get around 2 amps which is the designed output of the wall piece.
Maybe it works like the "Fast Charge" mode on custom kernels.
Charging is limited by 3 factors
1. Stock charger 5 Volts, then most importantly is the Amps - 2A for typical Samsung charger so going faster then this is unlikely with the stock charger, and tablets can already charge at 1890mA so probably 90% of its rated current.
2. Cable quality and length most Samsung cables are already high-quality and have copper wires with two bigger wires for the 5v and Ground line and they are short length (3-6ft) so they can easily handle 2A output (probably higher).
3. Probably the most important is the phone / tablet, usually they have several circuitry and software (kernel) protections to limit the charging speed for several reasons since lithium-ion / poly are extremely dangerous if they are overcharged or overheated or otherwise improperly charged (you can see videos of people overcharging lithium battery's then tapping them causing a huge fireball )
So it is very unlikely for a cable to achieve better charging speed, it probably just has the Data + - pins shorted to tell the charger / phone to charge at full speed (though this is unnecessary nowadays since most chargers already do this, but it could be beneficial for older phones / tablets)

You seriously spent $49 on a usb lead
From the link you supplied:
'When the switch is ON: All of the power is focused on charging, sync/data is disabled'
What, like using a mains charger where there is no sync connection (or buying a cheap charging cable where the data pins aren't connected)
Hes either a bot or someone paid to advertise that "product". It did remind me of "double your network speed" video from youtube where dude wraps one ethernet cable with another one and doubles his internet speed.
I saw this post a while back, and it was immediately clear to me that it was a scam. I can't BELIEVE that they actually raised over $400k on this thing. Indiegogo seems like it's becoming a scammer's conduit to gullible/uninformed buyers.
When did commercial posts get so frequent in here?

Apparently, there's a difference between buying a sd-card on amazon, or a glass protector on amazon compared with a pair of cables on Indiegogo. Although, I can't really see the difference.
Anyway, if and when I receive the cables I will let you know how it worked out.
Did you get your cables yet? Your OP says they were due in March 2015

Keep us posted! Im interested in the results.
I'll probably buy when the price goes down.
Seems like an interesting concept. I'd like to see the cable in real-world action. Assuming they actually make it to market, i'll buy when the price goes down.
Believe it, or not, but I actually received my cables last week. The charging speed is substantially improved, but definitely not 2x. However, I still haven't tried charging by connecting over the PC, where this might show up. Anyway, as a fan of gadgets I still satisfied with my purchase.
I'm glad your happy with your purchase.
Charging speed is limited by the circuitry in the tablet itself. There's a limit in the amount of amps it can pull from anything (charger/computer or any USB port). I have an extremely powerful charger so I'm sure I hit the max charging rate of my devices. This cable will not improve that. I'm also sure that it's actually charging faster and drawing more power than my original chargers as some devices act a bit weird when charged fast.
The "twice as fast" charging rate will be the exact same charging rate as you get from a "charge only" cable if (and only if) you connect it to a computer or another device that syncs data. In every other scenario you'll get the exact same charging rate.
Note that your computer typically has a USB port for charging that's capable of drawing more power than the standard 500 mA that USB 1 and 2 offer. (USB3 can draw 900 mA, up to 1500 mA if it's a charging port)
Keep in mind that the stock charger output is 5.3 volts.
Lower impedance cable helps.
Samsung stock cable is good enough, and PNY cable also does a good job.
You can have the same thing on eBay for $6 ...
http://www.ebay.com/itm/USB-smart-c...-Apple-Android-With-V-A-display-/141342314642
A charge only cable so you get maximum charge speed starts at only £5

Yes I got my cable, and the 2x works if you charge through your computers USB, as what the cable does is cutting off the communication to charge only. I saw a post at XDA that explain how to do this by yourself in about 5-10 min.

Trying to gauge interest for a pet project.
How many of you would be interested in an adapter that would allow you to use a laptop "brick" to charge your G-Tab?
First design is going to be for the Dell laptop power supplies (since I have a plethora of them )
If there is enough interest in other laptop supplies I will look at different connectors as well.
No idea on mfg costs right now, need to prove concept first. Cost target (Resale) is ~$10
I'd like to see and adapter that fits the Dell D and E series Latitude chargers.
That's the one I'm aiming for initially. Newer series Dell with the ROUND receptacle. I "think" it might still work with the octagonal receptecles though. Need to get some samples and try it out for fit.
Cost might be sligthly higher than I originally anticipated (Still <$20 though) - the damn Dell connector is a quasi-custom and cheapest I've found is $6+ shipping....grumble....
If the old receptacles work, that brings the cost down.
Haven't priced the tablet side connector yet, but I'm guessing it's going to be a couple bucks with a lead on it.
More to come....hoping to have some parts by next week to start building up protos.
I'd be very interested in something that would plug into a USB port on a desktop or laptop or any USB power supply.
I have a couple of D-Series laptops and would love to use the same charger for them and my G-Tab. I would definitely buy one.

If you have USB3.0 it "might" be possible as that has higher current carrying (3.6W) potential than USB1 and USB2.0 which are ~500mW at best. That's one disadvanage to the big ass battery in these things, which I think are 7.2V, so they usually require a higher input voltage (hence why we get 12V in). Even with USB3.0 though, we are still looking at long (10x+) charging times versus the wall-wart.
It's "technically" possible to step up the current USB 5V to 12V, but the power level is so low that it would take forever and a day to charge ( or about 48x longer than the current 12V/2A wall charger)
without a proper teardown though, it's tough to tell what the charging circuit looks like on the board. My guess is it's a 12V / 7.2V buck charger as it's cheaper than a boost/buck to implement. My bigger question about the internal charging circuit though is what it actually draws in terms of power...the wall wart is rated for 12V/2A, but those are usually overbuilt to prevent them from blowing up. Hoping it's closer to 1A draw, but again without knowing what the charger chip is, there's no (Easy) way to determine this without probing the connections.

Count me in as well. I travel a ton for work and having one less charger to stuff in my carry-on would be great - well worth the sub-$20 price.
I currently pack a PA-4E, stock charger for a Latitude E6510
I would be interested, though I have an ASUS laptop at the moment.
On a side note, if you did only decide to make one and it were for Dell, anyone could purchase a universal adapter and care the one adapter and two tips. Just a thought.
Hi Folks
After digging through mounds of tech docs, I was able to verify that the G-Tab uses the TI TPS658621A power management processor for charging.
Good news - you can plug just about anything into it from 9V up to 18V and it should charge it. Theoretically, it should also support step up charging from USB (trickle charge) but I've yet to prove that. (The power management processor supports it, but it might not be in the hardware.)
Bad news - it's just out of reach for a standard laptop charger (19V) so we still need a converter.
So, if you find a connector that fits it, plug it in. Don't worry about the current draw - as long as it's 1A or GREATER it should work fine (the device won't pull more than an 1A, even though our chargers are spec'd for 2)
Technical specs are available here - http://focus.ti.com/docs/prod/folders/print/tps658621d.html
This is awesome info! That means for the car all we need is a fused line to the right plug (center positive of course.)
This is great news, this means that the iGO tip that sends out 19v is safe to be used on the GTab.
Thanks for sharing.

While you might be able to do that, I don't recommend it. If you do it anyway, do yourself a favor and NEVER EVER EVER leave it plugged in while you are starting the car.
From Wikipedia:
A second problem is that nominally "Twelve-Volt" power in cars fluctuates widely. The actual voltage will be approximately 12.5 volts when dormant, (less when cold) approximately 14.5 volts when the engine and the alternator/generator are operating, (more when cold) and may briefly drop as low as 5-6 volts during engine start.[7] DC/DC converters will usually compensate for these small fluctuations.[citation needed]
Rarely, more extreme cases of voltage fluctuation can occur when the car battery is disconnected while the engine is running, or when the car receives a jump start. When the battery is disconnected, a load dump transient can produce very high voltages. A car receiving a jump start from a truck will be subject to its 24 V electrical system.[8] A "double battery jump-start" is performed by some tow truck drivers in cold climates.[9]
Design wise one has to take into account intermittent contact, and voltages outside the nominal 12 V DC like top voltage 9-16 V continuously, top voltage at 20 V during 1 hour, 24 V during 1 minute, 40 V during 400 ms.[10] Protection component tolerance example ratings are +50 to -60 V DC[11] Besides this there's also varying temperatures between -40 till +85 °C to contend with that can affect humidity and condensation.[10] Equipment connected this way must tolerate large variations in electrical- and climate environment.
For more, look at table 20-1 in http://www.fordemc.com/docs/download/EMC_CS_2009rev1.pdf which is reference [10] in the Wikipedia article. Granted, that's very conservative, but a 1A 12V low drop out regulator is cheap insurance for a piece of kit like our tablets.
Interesting. If you plug in tablet and that part number into Google you get lots of familiar looking pictures:

I agree, and thanks for the info. I do ham radio and already know to not plug things in until the car is running, actually learned that from xda years back from cell phone charging. I also use Anderson Powerpoles for the connections, very highly recommend these. This does mean that given the same precautions I already follow I can make up a nice charging cable pretty easily. And I'll certainly look in to the low voltage protection, just in case.

My husband just remembered that we bought a power converter years ago to charge a laptop while traveling in Europe.
Would this work without any problems with the Gtab?
Found the model here: http://www.crutchfield.com/S-jg9JaV...er-Pocket-Inverter-175.html?tab=detailed_info
You mean by plugging in the AC charger to it? Should work fine. The output of the stock charger is about 24W so even if it is grossly inefficient, a 140W power inverter should be fine.
Naturally, I assume no risk, yada yada yada, your mileage may vary, void where prohibited by law.
Hey, if it helps anyone at all, I bought this car adapter from the radio shack and it works well. None of the included tips worked with my Gtab, so I cut the tip off my included wall charger and using two of the adapt-a-plug connectors also available at the shack, I made it so I can use the tip on either my wall charger or my car charger. Just gotta remember to take it with me, and of course get the polarity right. Its a regulated 12 volt charger, so it reduces some of the spikes and drops from the car battery, the amperage is correct, and the on/off switch means you can wait to turn it on until after the car is started. Reduces the amount of plugging and unplugging nicely.

So I apologize for what I'm sure is a dumb question but I don't know squat about electricity.
Will this or will this NOT work with a Igo charger. Deals.woot (today only) has a 90W slimline charger that apparently outputs about 19V. The first post would lead me to believe this will not work while a subsequent one indicates it would.

Another member reported earlier that he has researched the power management chip on the GTab and it will apparently run up 18v, this justify why many has been using the iGO Asus netbook tip successfully for so long.
Now for the woot deal, I wouldn't bother with a "refurbished" item when you can get the tried and working travel adapter for $18 (shipped) and $20 (for the version with the auto and airplane adapter) there is a confirmed tip that fits the gtab included.

Best of luck,
The first post says the top end is 18V by the data sheet. Where have you seen someone quote 20V?
I've been using an iGo netbook charger for 3 weeks without any problem. I found it on sale at Office Depot for $8 the week before they dropped the GTab price to $300. Three weeks is probably only 7 or 8 charge cycles, but I've paid attention looking for hot spots, etc. and haven't noticed anything. I don't love the stiffness of the cable, but it was $8. I'm not complaining.
My only charging "problem" is that the silly thing wakes up when it hits 100% (VEGAn-TAB Ginger). Having the screen come on at full brightness just when I'm falling asleep was funny the first time, but it's getting annoying that I keep forgetting to power it off.

if it's the wire end, you can get new plugs at radioshack. But requires some soldering skill to get them on there.

I'm not very familiar with the iSound charger, does it provide a high enough Amp output?
When I got my Galaxy Tab 10.1v a couple of years ago, I bought some adapters that feature a resistor and a swap some pins around to ensure the device goes into charge mode and not data mode when plugged into a PC. The resistor enables a higher Amp output than you get from a normal USB port. I've checked ebay recently and found that there are even better adapters out now than what I bought in 2011, much more low profile.
Maybe one of these could help?

Thanks for your help
the output opportunity of your mobile power bank to produce the current with enough power Is significant . As example u can see my mobile Iconbit charger which produces two current opportunities: 2.1 A and 1A.
The first allows to charge my phone very fast, the second allows not to lose phone battery chargе during walking with maps enabled.
So, may be your's power bank is not quite good to output good current. may be it was very good in past but battery have lost the capacity and opportunity to produce current.
Also I've throwd to the garbage a lot of adapters which had lost their opportunity to put goodie high current, a lot of famous brands also. During the year and half of Note 1 I've changed five batteries and three wall chargers. some changes I have bought to replace did not charge my phone.

Some good points here - particularly about charges and cables to degrade and lose their capability to provide a quality current - I've had to dispose of a few cables and chargers as well.
Still, the adapters that discussed earlier can help to a certain extent.
I now have the new z2 tablet which seems great up to now, i have some touch issues at first, but since installing and using apex it seems to have gone.
anyway, im a bit annoyed with sony for moving the charging port to the top as i thought it was much better on the bottom, i could just sit with it and have it still charging, now being on the top it feels a bit strange being on charge and a little in the way, plus where i usually sit with it, the cable now feels too short.
so i was wondering if i got a 2m cable, would it actually effect the charge at all, or would it be exactly the same?
on ebay i have found a 2m cable which is only £2.95 it says its a charge cable, although one thing puzzled me, was that it says in the desc that its ideal for charging using a compatible 2000 mah adapter, but as far as i know, sony have stupidly left their charger as 1500 haven't they?
i can't understand why sony keep opting for this speed when all others seem to do 2000 or alightly more, it just leads to the tablet not always charging properly when you are also using it.
anyway, does anyone know if i will be lowering my charging power / speed if i get a 2m cable?
thanks
James
It is not the capacity (mAh) but the charging current (mA) that counts.
This tablet has a (very?) long charging time and thus a low charging current.
A cable with a little bit extra resistance won't make a big difference then.
I bought a cheap magnetic cable (1m) and am perfectly happy with it.
I'm in the process of testing the various cables and chargers I got at home (about a dozen of chargers and twice as many cables).
The first noticeable things: they are definitely not all equal and the provided ones are NOT the best.
So far there's only one charger that provides more than 1A CONSISTENTLY and it only works with the shorter cables (I got between 1.1 and 1.2 A with a 1m cable vs <>0.8A with a 2m one).
I started testing because I think the biggest bug with this tablet is NOT the touch problem ( i only updated yesterday and did not use it very much since but it seems resolved with the last update) but it can't charge when using power hungry apps. I've been playing XCOM a lot lately and NONE of my chargers/cable can keep up with the power consumption while playing.
But yes cable length does matter.
Through my testing, i would say that shorter cable gives me lower resistance=better charging rate. Tested with 3 different length, 21.5CM, 1M, 2M. 21.5CM cable gives me the best result
20cm or 2m, realistic the difference is not gonna be noticeable at all. The difference in resistance is negligible.
Sent fra min SGP511 via Tapatalk
my 512 charges faster if I plug in the cable into the port then it does if I use the magnetic adapter and the same cable using the bottom, and also charges faster in the dock then it does using the magnetic adapter. Go figure.....
With low quality cables, longer distances can absolutely affect charging rates.

One great way to tell is some cables have the gauge of the wires printed on the outside of the cable. I believe 28/28 is minimum for USB 2.0 but that is for 500ma charging. Look for 28/24 or better (lower numbers are better), especially for longer cables.

Thanks, I did not know about wire gauges.
Unfortunatly, it does not seem like it easy to know which gauges a cable use, I've got 7 different cables on my desk right know and none of the have the information printed on. I'll check the rest when I get home.
There is absolutely no question that cables make a difference.
There is absolutely no question, as well, that chargers make a difference. Many of them are mislabeled.
I bought this:
http://www.dx.com/p/usb-av-usb-power-current-voltage-tester-translucent-blue-silver-235090
And used it to measure how much power I'm getting out different charger/cable combos when charging.
It was especially useful for the car, since my phone needs a LOT of power when it's in full 'navigation/streaming music' mode.
Whether longer is better than shorter depends on a lot of factors, but I will say my best charging cable is my 6 inch cable.
(which is just fine for the car)

The device I posted the link to sits is a usb pass through. You put it between your charger and your charging cable, and it tells you how much current is going through.
- Frank
There is no real rule-of-thumb regarding just the cable length.
You just cannot tell that some (!) shorter cable is better than some (!) longer cable.
Just because there are more factors involved - like core diameter, insulation, core material, and the like.
In general: If you use exactly the same cable type, the shorter variant will show better results.
If you use mixed cable qualities, you have to include more factors into your calculation.
Best way: Give it a check. You don't need adapters (although this is the better and faster way), you just need to recharge your device up from the same power level to any other given level, e. g. from 10 % to 90 %. Do not charge up to 100 %; on the "last mile", there are some more factors involved which may affect the results.
Take the time charging from e. g. 10 % to 90 % needs, discharge the battery by using the tablet with full brightness setting, repeat the same with another cable.
You'll soon find out which cable enables faster charging.
Suggestion for recharging the Z2 using the DK39 charging station: Samsung's white 2 Ah power supply, standard accessory provided with the S4 and other smartphones. Real fast using DK39, slower via USB.
I've been looking at different Micro USB Charging Cables for my brand new Nexus 6 and I want to make sure that I'll still get the benefits of the Faster charging with a different cable. I found this, but I have no idea if any 3rd party cables can be used.

That cable will work fine. Pretty much any 3rd party cable will work.

Do NOT buy any cable from anywhere else. Unless it's cheaper, but it probably won't be. Their stuff has always been great and the selection is awesome.

If you buy from monoprice and want a cable over 3 ft then you have to buy a "premium" cable and that costs more. I got this one on Amazon, it will give you the full charging speed at 6 ft or more:

Keep in mind that to get the full speed with a cable longer than 3 ft you really need to get something like 24/28 AWG otherwise it can't carry the charge. I bought a bunch of 28/28 cables and none of them gave me the full speed. At 3 ft pretty much any cable will work.
10ft cable that is 28/28 from Mono Price is $1.27

28/28 isn't going to work. I bought 6 and was very disappointed.

It actually does work, IF you are using a QuickCharge charger. They increase the voltage, and lower the amperage. This in turn causes lower voltage drop over the cable, making the size less relevant. I have a pair of 10ft Monoprice 28/28s here, the charge speed is the same as the cable the phone comes with. Once it drops to 5V, the battery is already only allowing small currents to top it off anyway.
With a standard 5V charger, that article is dead on. And all things being equal, you generally do want the thicker ones, so do get them if they are available.

If it works for you then I'm envious, but I've got 3 Motorola chargers, 3 Nexus 6s and 8 6ft 28/28 cables that aren't doing it and for my money that's a pretty good sample. I only have all these because I manage the phone plan at work. When we bought the 24/28 6ft cables we had no issues.
