Can you use the hub without the power adapter?

NO! It is a powered hub. Having said that, I love these puppies. I've got 5 total in use and highly recommend them. (See my earlier review.) on USB 3 items, they'll draw power from their own power supplies and the computer itself, you DON'T ever want to take a chance of burning out the USB on your puter or the device (Like hard-drives) due to a low power situation, EVER!The plugable 7 port hub is lighted to let you know when the device is properly connected and powered, on each port.

Having the item on my desk and the USB cord disconnected. My Cell Phone plugged into port 1.The Light on the hub is out. BUT the phone is saying it is charging.

Its here on my desk top right now, thus it is easy to verify your question. NO, the unit immediately went off line and disconnected. Upon application of the power it came back on line. I selected this unit for two reasons:USB 3.0 and the higher current capacity. I have in the past been frustrated with "low cost" hubs that won't charge a phone for example.Hope this helps.Michael

Hi Aaron, I just tried out, and NO, you can not use this without power adapter

Yes. However it depends on the device you are plugging in. If the device is BUS powered, then you will need this HUB to be plugged in a power source as it will need to send power to the bus powered device (for example flash drives or USB powered Mics) If the device has its own source of power (like a camera or a powered external hard drive) then you do not need to plug the HUB into a power source and can serve as a pass through.

No, it won't work without the adapter. One port wouldn't supply enough power for that.

Yes. Using it is no different from charging it with a power adapter. But it will be physically awkward if you are not at a table or desk.

The manufacturer says this: When the hub's power adapter is not connected, the hub is capable of running purely from bus power (from the host PC). When a hub reports itself as bus powered to the OS, the OS looks in the USB descriptors for every attached device, sees how much power the device reports that it needs reserved for it, and pops up a error (and possibly disables devices) if the total amount of power requested exceeds what a bus-powered hub in theory can count on pulling, which is 500mA for USB 2.0/1.1. We recommend always using the power adapter for best results.

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.

No, it will only work with a computer and cannot be used as a hub for power.

If I understand you right, yes. The hub is powered and will provide power to any thing plugged into it (optical mouse, keyboard, Thumb drive). The 2 "high" power ports are for fast charging something but does not fast charge if the hub is connected to a PC. They supply the usual USB voltage.

The power supply plugs into any standard electrical outlet (110-115 V). I have not tried using the hub as a bus-powered device.

You can use it without power. I haven't tried using it with multiple sticks without the power adaptor though.

Hi Nicolas Raddatz, No, this hub is self-powered, so it needs the AC adapter is plugged to ensure stable performance. Anker Team 1-800-988-7973 support@ianker.com Mon-Fri 9am to 5pm(pst)

Yes, I'm using it with one now. But it will need two USB ports (unless you buy the power supply), and a hub won't work. You need a card or the original ports.

The hub will NOT work with out power. I tried it out with one USB drive and it will not read the drive until AC is added to the unit.

Yes. It doesn't need a power adapter but it will need to be plugged into a power source via the cable that comes with it.

Yes, it can be used without connecting the power adapter if your USB device power requirements are low enough. The only power available in that case would be the power supplied by your USB port on the computer, usually only 500 ma.

No. This device does not need external power. Direct plug and play ( like a thumb drive)

The hub needs to plug into an electric outlet for power ( it's not just USB powered ).

Experimentation tells me that the answer is NO. My experience with bus powered USB hubs has been problematic. Commonly you get a "power fault" on one or more of the devices involved and restoration is very difficult without rebooting (ugh).

it does not need a power adapter. will power up with out one. so far this hard drive has been really good
