The power cable included is to feed 5v from another USB port on the laptop TO the ExpressCard adaptor for all but low pwr devices attached to adaptor?

The power cable is to power something that needs usb power. I've install 5 on older laptops but never had to use the cable yet.

You are correct on your question. I don't use the power cable for my external hard drive

I didn't need the power cable when using one external hard drive but I did need to hook up the power cable when I added a second external hard drive to the second USB 3.0 port on the card. The power coming through the card from my Dell E5510 notebook computer was not sufficient to power the two external hard drives (one was a Western Digital My Passport and the other was a Seagate Backup Plus).

Mine came with the 90 Watt power adapter and the power cord, although the same adapter and cord that I already had with the ThinkPad notebook would have also worked with the dock. These docks are no longer being made or sold by Lenovo, so they are either leftover old stock or refurbished, and are being provided by third-party sellers. Mine came from a different seller than the one Amazon is currently showing, so I think you need to contact the listed seller and ask them the question directly (if you click on the seller's name in Amazon's listing, it will take you to the seller's page where there is a "contact seller" link).

No, ExpressCard and PC Card (PCMCIA/CardBus) are different lengths, different voltage and not compatible.

None... However, you must USE a separate power supply for the adapter. You must use at least 5 volts @ 2 Amps or 2000 mili-Amps or higher. It is use to power up what ever device that you going to use. Having a USB to power cord which came with the adapter is NOT good enough. My adapter plugs in deep into my laptop. I have problems with some USB devices because of the thickness of the USB end. It gets in the way of the laptop case. I use an extender to help resolve that problem.

Nope. This adapter has the second cord which has to be used in order to power the laptop via the wall outlet.

The DC charger that is included in the package is NOT needed to run this unit. It is there for additional power for some of the more power demanding units such as certain external hard drives. Laptop USB ports usually only offer 500mAH of power.

Plug the GMYLE PCMCIA card into the laptop. Plug USB device(s) into that card. If the USB devices work without using the power cord, you don't need to use the power cord. Some devices get their power from the card. The card supplies a certain amount of power to devices. If that amount of power is not enough for the devices, then use the power cord as follows. Connect the power cord to any USB port on the laptop (sometimes there are 2 USB plugs on the power cord that can be connected to 2 USB ports on the laptop, for even more power). Connect the very small plug to the small round hole that is between the 2 USB ports on the card. By doing that, the USB ports of the laptop provide power to the card so the card can provide power to the devices that are plugged into the USB ports on the card.

No - it is only for an ExpressCard slot, either 34mm or 54mm. This is similar to the older PCMCIA card slots. It is no longer a very common item on today's laptops but it does exist if you look hard enough.

yes but you have tu use the 6 pin power adapter conector and don't forget is a PCI Express 2.0

Hi Zachary ... Appears this is not what you want. [I am unclear if an Airport Express can be powered via USB and not its own power adapter.] This specifically is a USB-to-serial data cable with a built in UART chip. There can be very low levels of 3.3v or 5v generated (varies with various models) but that's not gonna drive a whole big device like Airport - more to drive one or two chips on a small board. This is designed for making your USB-equipped PC - desktop or laptop - look like it has a built-in COMn: serial port. FYI, "TTL" means transitor-to-transistor logic levels (meaning 5VDC), and Tx & Rx are the UART lines for transmitted & received serial data at logic level (not +/- 10+ VDC swing used by actual RS232 line levels).

You need to connect its included power adapter to one of the power connectors on its included power/data cable.

Your card get's it power through the motherboard via pci express 2.0. Not seperate power cords from the power supply.

Not sure. But on my ASUS laptop the prong inside the DC in power jack board was loose and eventually broke off inside of the power cord charger connection. I replaced the DC in power jack board and it fixed my problem.

This item doesn't require any external power connectors; it only draws power from the PCI Express slot. Hope this helps.

I just connected the card to an existing Molex 4-pin power connector from my computer power supply. If you have a spare Molex connector already, you're all set (if it's long enough to reach the card). I don't recall if an adapter cable for LP4 was included or not (if it was, it's now in my bin of spare parts).

Yes, that's basically it. Put it in and insert the power cable (on the top of the card).

No. The power adapter is only needed if the devices connected to it require more power than the port on the computer can provide.
