if i keep the usb power plugged in does it stay on and run from the usb power?

The short answer is yes. The unit has an on/off switch. The USB cable will charge it while off and charge/power it when on.

My guess is that it will work just fine - plug it into a spare USB port and it does the job. If you want it to stop, just pull it out.

I have left mine connected without being plugged in for a few hours without a problem. But I don't know about permanently I have never done that.

Nope, as long as it's connected to a power source it will always remain on even if no cable is connected

Nope! It runs on the USB power so all you need to do is plug it into your PC.

Not that I know of but the light stays on, unless you just want to unplug the usb?

Yes it does stay on the entire time. It will not drain your battery if you leave it plugged in. Me personally I just unplug mine. It will save the station you programmed. Hope this helps. I enjoy mine.

No-- the device essentially turns a single usb port into a multi function peripheral that is feeds the appropriate signal back into the primary cpu. It has its own power supply and remains on even when computer is powered down.

If its attached via USB then yes, it shuts off then when you restart your car, it turns back on.

On my unit if the power plug gets pulled when it is on it comes back on. So if the unit is own a power strip and the power strip gets turned off the unit will power back up. I keep my unit on my desk but keep it powered off unless I need to use it.

No it won't run off USB I imagane that the designers figured you would not be useing this away from a power source.

One more thing, if I unplug the USB from the plug to use stand alone without extra power, but to use the device's charged power, it works fine also.

No it will not run off a wall outlet. It's suppose to be for your computer.. and since it's connected to the computer motherboard, it uses a DC voltage output from it.This is also not a USB fan. Based on your question, it's likely not what you want or need..

No. Once it's plugged it will turn on perfectly. Once unplugged, it will turn off and rest.

You just plug in your USB cord and it automatically turns on. and when you plug the cord out it turns off

If you keep it charged (as in, constant power connection), then yes, it will continue to stay on and record when needed until you turn it off.
