Do you have room to actually plug 4 items in - none would be USB?

If the plugs are of "normal" size then yes you can fit 4 items. I don't have any that are over sized and have never had any issues.

It's runs 4 outlets. You can get a USB adaptor at Walmart. This is perfect for people who run yellow lights or emergency lights through a 12v outlet

It depends on how big your plugs are but they should all fit without any problems. I havent had any issues.

Mine does not have that option. I can see where there's lines the size of USB and SD ports but they aren't really openings.

the one I got would not work for that. Only 2 of the 7 usb ports worked and if I tried to use both at once it would not power the devices.

there is also an adapter you can get between $7-$12 depending upon where you purchase it...it will allow for other size usb to fit without issue

No. Just two USB ports. One for power & data and another just for additional power.

There's no USB port on the plug, just two spaces where a pronged plug in could go.

Unfortunately, no. I would recommend adding a multi-outlet adapter if you need more.

No. This has the type of USB connection that you plug into something else, not that you can plug things into.

Just remember that if they are all power hungry devices that there is a limited supply of power on anything USB related, in this case you have 2A limit, or approximately 4 full power devices (USB 2.0 has a 500mA cap). If this doesn't seem to be the problem, maybe you just got a bad one.

No Usb needed However this is not too reliable maybe a different brand may work.

Yes. You have have 2 AC Outlets and 1 USB Port. Should do the trick for you.

never tried, but since it is merely an extension of usb ports, it should work like an electrical extension, whichwhen in use would allow several plugs to run off one outlet.

No. There isn't room on the face for any more stuff.With two source devices plugged in, you turn one off and then turn the other one on.

There are 8 USB ports, 2 in front and 6 in the back. Not sure if they are 2.0 or greater or a combo.

I think you can have as many of these as you want. Just need to have the USB ports or a bunch of usb hubs.

Had only 4 devices plugged in at any one time 1 HP printer & 3 external hard drives. All worked at the same time, but as I reported connections were not tight enough and if wiggled or accidentally hit, one or two would disconnect.
