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?

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.
Hi,
I have just bought the galaxy nexus and am wondering if any of you bright bods could think of a way to do this. I have a Fiat bravo with blue and me so use the usb port for media playback, however this does not supply enough power to keep the phone charging if using navigation too. I also have a 750mA 12 volt charger. Is there a cable that would allow me to have both the media player cable connected and the cigarette lighter cable connected at the same time, preferably with d- d+ shorted so that high speed charging would be available as the effective power available should be 1.2A if my thinking is correct
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?
I have a cable which plugs into my charging port which then has a usb slot on the end. I want to watch films on my tablet which I can now do but I also need to be able to charge the tablet at the same time. Is there some kind of double socket I can plug into the charger point that I can then use to plug the charger and my existing usb cable into use both at the same time? What would this be called, I've tried searching splitters and adapters but this only seems to come up with car chargers which is not what I need.
Thanks!

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.
