If I were to purchase a generic USB adapter to plug into an outlet to power this light/fan, how powerful would it have to be to power this device?

It will operate on generic USB hubs that pass +5 volts from your computer USB jack. Not all laptop and notebook USB jacks will do this. In that case you will need a USB hub with an external 5 Volt supply.

It takes awhile with the regular cord, I bought a stronger wall plug, I believe it was a 10W. Usb with the regular wall plugs don't give as much power.

Yes it is a safe bet this unit is going to need power to do it's magic. So if you can shoot 12V dc out of your fingertips, you're all set. If not, the adapter will the way to go.

The fan only needs to be plugged in to a USB to run at full speed. In order to use the USB plugs at the base of the fan you have to buy additional power adapter.

If it supplies the 5 volt power that all USB devices use, then it can power this fan.

This hub is underpowered by almost 45%. USB 2.0 ports should be able to pull 500mA, so with 7 ports the AC adapter should supply 3.5 Amps. It only delivers 2. Almost every powered hub on the market seems to be similarly underpowered.

It's 15 amps, so this will allow a device to pull pretty much the maximum current from a typical wall outlet. Anything requiring more current than this can handle shouldn't be plugged in to a typical wall outlet anyway.

A common USB outlet offers 5V at .5AI recommend any power adapter that has the same power output

Prior to answering, I carefully reread the instructions. No where is this question answered or addressed. I simply don't know. Technical info from instructions:" Power requirements: DC Adapter: 9vcd, 500 mA. Sorry!

The power adapter it comes with plugs into the wall and takes 100-240VAC. It provides 5VDC at 2.6A. This means you could power up to 5 devices at the maximum rated USB power (500mA each). It should be more than enough for standard peripherals (keyboard, mouse, printer, webcam, etc.)

On the unit is a mini usb with standard usb on the other end that plugs into computer or charging unit. I suspect you could plug into any usb but have not verified wattage needed.

Any USB wall plug of any voltage will work. If you can charge your smartphone you can run this fan.

I don't think it needs to be a "high" current usb. I have been running it about 12 hours a day on a regular usb adapter. It does have a battery, which I didn't expect, and really like as you can disconnect it from the adapter and it will give you a portable light. I really like this little desk-light. I hope this helps!

Simple just plug it into a usb outlet that has a power supply like a computer

I am not familiar with this. I guess you would have to look at the "specs" of the "thing" you want to plug in and see what it's power requirements are.

Yes. Keep in mind though that you'll probably need to use two USB cable spots to power the device. It's unusual but works fine.

Yes, you can use either the adapter or the USB cord to get power.I use it to conserve USB ports.
