I understand the thinner the internal wires in a USB cable (the AUG), the more resistance there is meaning slower charging. Also the longer the cable, the more the resistance. So the lower number AUG (eg. 24AUG) the larger the potential for faster charging.
But does that mean if I plug the charger of my android tablet into a 4 socket extension cable of say 2m, it would add to the resistance and mean potentially slower charging?
Note I'm not talking about a USB extension cable, but a mains plug extension lead. This is where I got my initial info, but it doesn't mention if the same is true for mains extensions:

Anyone?

Is there a way to charge ya phone through the USB as quick as it would charge through the mains?
It takes for ever to charge through USB?
No. Because USB hub doesn't have as much output as charger.
I know standard usb gives 5V
how much does the wall charger give??
I have a freeloader solar charger, and don't know if I can use the 9.5V output on my desire.

It's not the Volts that's the problem its the Amps
The wall charger provides 1A, a USB connection provides 500mA, so half as much.
Ok thanks people
Never tested never heard about but maybe a Y-cable (2 standard A plugs on one side, a micro USB A on the other side) is what you are looking for. It provides the 500 mA from two individual USB ports. However, you have to make sure that both ports can supply 500 mA individually and simultaneously! E.g. a passive USB hub will not work since all USB ports have to share the 500 mA from the host PC. You would need a powered USB hub.
Get a cheap USB cable extender.
Cut it open.
Short the 2 data wires (white and green)
Tape it back up.
Use this in-between your normal USB cable and your USB port.
I'm guessing probably not, but the faster charging times would be a great plus. Charging over USB 2.0 seems rather slow compared to proprietary connectors like iPhones, etc. It micro connector should be backwards compatible if you only had a 2.0 cable anyway. It shouldn't impact the design of phones very much since it's just a little wider.
Correct me if i am wrong but It should charge over usb 3.0 faster as usb 2.0 can supply 5v at 500 mA whilst usb 3.0 is 900 mA. Regardless of the connector like the proprietary apple connector it will not charge a device any better as it still is constrained by the usb standard. This is not to say you cannot run more amps though a usb cable connect to a wall connecter as i have a usb wall connected that runs 5v at 1 amp and it charges pretty dam fast.

I don't really think so.
the number of USB 3.0 "actual" user nowdays is still low. and the price for it right now is also ridiculous high compare to the standard 2.0.
But who knows? maybe i am wrong... USB 3.0 is a nice feature to have.
Hey guys,
anyone know why issit that when I use a usb extension cable, altho only 0.8m, to connect to a usb 2 port hub, which is connected to a charger, the charging rate drops to trickle rate?
When I use the charging hub directly with the charger, charging rate was fine.
Is this due to the 0.8m resistance power drop along the extension cable, or what?
Would it be the same if I use a 90 degree usb male to female adapter?
First, the Nexus wireless charger works fine with its own AC adapter, and also in my car with a USB car charger. Kill-a-watt shows a 6-watt draw, and the "Stay awake while charging" setting is ignored.
But the cable is short and very stiff, so I tried 4 different standard 6' cables and none of them will charge. So is the wireless stock USB cable proprietary?
I noticed many posts about modifying a standard USB cable for charging, but some are misleading as to the purpose. If you plug a modified/proprietary cable in your computer for data transfer are you at risk of shorting the motherboard?

You need to use quality charger with 3.0A for that
a good/proper usb-c to usb-a cable is supposed to have a built in resistor to keep the device from pulling too much current through the older usb-a plug, which ofc wasn't designed with the capabilities of usb-c in mind.
therefore you should not be able to charge as fast with said cables, otherwise it wouldn't be too unlikely for your device or charger to get seriously damaged.

To be more precise, the resistor doesn't keep the device from pulling too much current, it tells the device it is connected to a legacy cable and it should limit to .5, .9, or 1.5A. The device can still choose to pull more current if it has alternate means of figuring out the capabilities of the power source. It won't be using facilities within the USB C spec, but it will still work fine.
My bedside combo of a 2.4amp charging brick, anker powerline 10ft micro usb cable, and anker micro usb to usb c adapter gives me quick charging. The cable and adapter also allow data transfer and adb from my macbook pro.

In my experience 5x says "Charging rapidly" around 1.6A. Some of the legacy USB A -> USB C cables (either direct or through micro-usb adapter) can get around 1.6A and 5x will display "Charging rapidly" but this might not be the same rate as the stock USB C native charger with which the device can pull 2.6A for the lower battery ranges like 0-40% before the phone slows down to around 1.8A (and even slower later on in the cycle)

Discovered this after returning my 5x, picking up a 6p, and installing ampere. Still functional as a bedside charger but thanks for the help tho.
