Are all mini usb cords the same?

[eclipse01]

I feel like random mini usb cords charge my Nexus 7 slower then others, and sometimes can't even keep up with me using it.

anyone else experience this?

Most of them are the same. Some devices like Motorola's have a special factory cord that can be bought for recovery purposes. It has an extra resistor in it to charge the device without it booting. Beyond that, they're all just copper wires

No, they aren't all the same. Some connectors have shoddy construction and poor shielding leading to decreased data throughput and decreased amperage for power.

There are also cables whose connector pins tend to lose their 'spring' quickly which makes the connectors slip out of the slots easily.

It is well worth the extra money to get a good, quality USB cables. I have had my share of cheap ones and its just not worth the hassle.

They are not all the same. Hopefully this post from AC helps you out.

"the cable that comes with the N7 is a standard USB charge/data cable. However the charger that comes with the N7 has the data connections already shorted. To get the same charge rate with a standard wall charger, you do need a data only USB cable (has the data pins shorted). If you use a standard charger and a standard cable, so the data connections are there, the charge rate will be very slow and may not show as charging at all."

I am using a micro usb cable that came with my Bose bluetooth headphones to charge and transfer with a Sony camera and my HTC M8, works good.

what is powering the usb cord is the biggest difference, car and computers charge slower than a wall plug, and the power adapter that you plug into the wall also makes a big difference. Most are rated at 1amp but some are 2amp and in theory can charge twice as fast if your device can handle it.
