I do not see a power button. Is there really one or is that an error in the description?

It does not have a power on off button, USB hubs I have had in the past with power adapter did not have a power button. you need to plug in the power adapter and it will remain on till it is pluged in to AC, if you disconnect the AC adapter it will function as a normal USB hub but will not be usable for charging devices that are power hungry. You could still charge cell phones or smaller devices. Hope this clarifies.

The unit does have an external power supply. Unit works well, no complaints here.

Might be a lose battery. Try to put a slight pressure on the battery while pressing power button. Also try to remove and re-install the battery.

Yes. One of the two thick stickers included should be on the power button of the unit to the left. That thickness allows you to slide the unit on the right to the left to engage the power button of the left item. Right? (He he, I couldn't resist ;)

Each port has it's own power button. Make sure it is on for the port you are using. You can also try a different port on there.

Beth - There is power on button lower left on the control box. Is a circle with line coming down from the top. Try that and advise.

Yes. The power button is located just to the left of and above the two circular vents on the right. When powered, it lights up with the same green color depicted. It is diamond shaped.

As you are looking at the screen, in the top right hand corner, there should be a power button/power indicator. Press that button to power the system on.

Press and hold the power button for at least 3 seconds. That usually works.

Try Pressing the Power button for 30 Secs or so, it takes a longer button press than the instructions tell you to press the button.

It does not appear to turn on when power is applied ... which is why I will be returning it. It requires pressing and holding the power button for ~3 seconds.

It doesn't have a power button. Mine would stay on all the time in certain plugs and was never an issue. It works very good and for the money, it is durable enough. *****

On mine there is a power switch on the back in addition too the button on the front. You have to have the switch in the back on (1) before the power button will work.

There is no power button. Unit plugs into OBD-II port and is powered up when the key is turned on.

It wasn't noted when I bought it, but found out AFTER I got it that it was a refurbished unit. That thing was a piece of crap that was pretty much DOA and wouldn't even power up after a couple days. Good Luck!

You double click the power button and the light will turn off, do the same to turn it on. The directions were in the very small and hard to read manual you received with it

I had an issue where the power button needed to be pressed repeatedly in order to start it. This kind of an issue is being reported all over message boards. I did an exchange on mine to see if that would help.
