Are all USB extension cables the same?

[ironk]

I am looking for USB 2.0 extension cables, and some people are saying that some of these cables aren't able to pass a charge? Is this true? If so, which one should I get? Link would be great.

I found these, not sure if they will pass a charge:

If its advertised as a USB2 cable, it should handle 500mA without problems.

I would trust monoprice cables over some generic brand, but as Insert Nickname said, if its advertised as usb2 cable it work.
Also looked at the customer reviews, 1 uses it as a extention cable for charging and xbox360 controller and another uses it on an iphone 4.

so you should be good

If all the contacts are connected properly and the wire size is big enough there shouldn't be any problems passing enough current.

I have about a half dozen of these - different lengths and makers - never have had a problem passing specified charges.

Depends on what you are plugging into what. Lots of USB devices are not quite spec as far as power draw goes and lots of USB ports, particularly laptop or low end desktop, do not deliver quite the advertised power. Normally everything manages to get away with it, but for long extensions issues can show up. If the device on the other end is behaving flakey just stick a powered USB hub int he middle.

There are such things as active usb cables. I don't know how they work exactly but I've had 25' usb runs not completely work due to the distance before. Active cables solved the problem.

You can see the difference on the female plug.

I don't know how they work exactly

Simple. They use the available current (500mA) to drive a signal amplifier...

Don't try and use one for charging anything for this reason.
