what does this device do electrically? if i use a quality short cable, this would be superfluous, yes? it can reduce the resistance of long wire?

"What this does, is to short out the 2 data wires in it, so the phone thinks that it's plugged into the wall, and therefore attempts to draw maximum power." It is actually more complicated than this. Most high powered devices today, i.e. need more than 2.5 watts to recharge their batteries, also need a voltage on the data pins. That is why the Apple dongle is different than the "universal dongle" which is by no means universal.

Use a quality cable, and I'd think the shorter the better. Neither of which would make this product superfluous though. What this does, is to short out the 2 data wires in it, so the phone thinks that it's plugged into the wall, and therefore attempts to draw maximum power. I tested this over and over with a Mediabridge adapter that has usb ports. The only way i could get the usb ports on it to draw the same amount of power as I'd get from plugging it into an outlet, was by using this device.

I don't have a cable to test this, my car cable is small HDMI, this requires a large USB. I think what they did is since they are taking up the electrical outlet, they allow you to continue plugging in the USB for other charging, say the phone with the battery inside.

It is not the intended purpose. You could cut off the end, run the wire through the wall, then attached an in-wall female connection, but you are better off just getting a spool of cable, you get much more cable for the money and it saves you the annoyance of cutting off and wasting perfectly good cabled ends.

This is only intended to be used as a "pass through" for wiring&gt; I used it to pass some USB and HDMI wires through a wall. It is not intended to support anything.

In all honesty unless your goin to have a much longer cable it will make no difference performance wise. So far this give crisp clear signals for me. That length should not be able to make a difference in the performance

It can tell you *which* wire is bad, but cannot tell you the *distance* to the break. In other words, it would tell you that the wire connected to pin 4 is not conducting, but would not tell you that the problem is in a kink 12 feet from this end of the cable. I believe that the tools that do that are 10x more expensive.

The cable is only about 25cm (less than a foot) long.But that is part of the concept to keep electrical resistance low. I have tried other, longer cables, and they reduce the power reaching the device by up to 50%! The fast charge cable does exactly what it should do: bring as much power as possible to the device.It's not meant for woring with the device while charging, and it won't allow data transfer either. It's just there for fast charging, nothing else. And that's what it does.

I have seen no drop in performance but with any cable there is slight resistance over the length. With this what you would lose should be negligible.

I wouldn't recommend it because you'll be amplifying a signal that will be weak/bad/grainy after traveling through the long cable. So it may amplify the "bad" signal. Generally it is best to amplify the "good" signal at the beginning of a long cable run or before you split it multiple times.

every electronic device give off emf. try to limit your expoure to it by moving further away from it.its geometric double your distance and you reduce it by 1/4.

assume you wall outlets will power other devices (ie, night lite). length of cable, within reason, should pose no problem. power adapter or 2400 unit possibly bad. may have to return for repair. with shipping cost, etc.... If it were me, I'd go to radio shack and pick up cheap 15 VDC 300 to 500MA adapter and try it on unit....you would need to adapt to coax = tell salesman what your doing = maybe he can help.

hey thanks for the reply. Do I need to buy another cable to make the connection ?

It was marketed a RCA. From what I understand either works. Its a matter of shielding. I am running this cable next to six other cables without problems.

With digital cables, it typically works or it doesn't...so you shouldn't experience a loss over distance. It's the source that unusually determines the length of cable it can handle. So far I've plugged it directly into a directv receiver and most recently an hdmi splitter, and both worked perfectly. Where I might be concerned with length would be things like a video out port on a tablet or laptop, but i'm sure that varies by model.

I suspect it won't matter. But I'd use ONLY shielded wire so stray signals over the greater distance won't interfere and give a false reading. (Try grounding the shield and ONLY the shield and ONLY at one point. If you ground a shield at more than one point, then a complete 'circuit' is made and interference is more likely.)

If you are going to use an extension cord get a good thick gauge one. A cheap thin cord would probably provide too much resistance.

I am a electrician and just installed six units in a kitchen and found the cables longer than needed. You will end up snaking the cable to take up the extra length. I will try to post a video of the job later this week.
