Hi, you don't need the ac power supply but I went with it ti have more power and I am glad I did, would do the same next time !

The cooling pad plugs into a USB port on your laptop. It is powered from the laptop. I always run mine with my laptop plugged in so as not to strain the battery, but it can be run on battery.

Power is provided by the same USB power running the cooling fan. No additional power cable is needed.

It has 4 usb ports, but only outputs 24W of power. I had trouble charging 2 android tablets at the same time when the batteries were really low. Look at your chargers that came with you laptop and gopro and see what wattage they are.

It does not provide power to any device. It is powered but does not provide power (other than through the USB ports)

No, it doesn't need anything else. Just plug in the USB and it gets the power from laptop and start working. It also has 2-speed to choose.

It requires auxilliary power. USB won't power it. But it comes with a power pack.

What do you mean a wall plug in? It does come with a AC power adapter and Internet plug in. Once you download the driver to your laptop, it will fit most laptops.

I'm not the seller, sorry. I'd suggest looking up some installation guides because it can be a little tricky I had to buy a powered USB hub when I got mine.

No. It has to be plugged into the wall. The USB hookup is fine, but not necessary. You get two cables: 1. The Power Cord 2. The USB Connector I rarely use #2, but #1 is a must. =) Hope this helps. ~Mick

Some laptops do not apply full power to the USB ports, if it runs on one your computer supplies full power and you do not need the extra plug.

No, it doesn't need a separate power supply, it can draw the power from USB port on a laptop. If you intent to connect it to an USB hub, make sure that the USB hub can provide sufficient power. Non/low powered USB hub will not work.

you plug it into a wall outlet and then into the computer with a usb cable. so the power does not come from the computer

I'm from Norway but study in the states so I travel back and forth when I have vacation and you can just buy a cheap plug. The power brick takes care of all the voltage conversions. This applies to all laptops.

There is cable that comes with the Star Tech, it plugs into the side of the card and the other end is USB no charge box is provided but I have 3 that I use for various devices. A power supply that plugs into the wall and has one or two usb outlets on it. I did NOT have to use the power supply cord. That is provided in case your laptop does not have enough power for the devices that you plug in, or your usbs are already overtaxed. If you are just using flash drives for instance you will not need the added power.

You need to connect the AC power to power this 7 port hub. It come with the unit.

Hi, The other answer is correct. Some do come with a seperate wall plug for power, but this one has a USB-powered adapter.

In general, I have found that the USB hubs that supply a wall-wart for power to the hub, do indeed NEED the power to the hub.Dick

The unit comes with a USB cord to plug into your laptop to charge. Or you need to purchase a USB wall charger.
