It is powered through the USB port. Just plug into the USB port and it is ready to work.

Sorry, but it is connected to power and my power hasn't failed. As I said the customer service is A1 and you should ask them for details.

if no light, then it is not on. My own stopped working after 2 days and I returned it to the seller.

Without power the timer doesn't work. You would have to reset it like a clock.

No Judith, it plugs in. That was not really a problem for me though. The power is.

Without light on or with light completely removed? It works without light on

Nope. It works without any external power source and yes it works just fine.

I don't know. It has been subjected to a couple of sudden power outages, with the UPS backup taken over, with out any problems.

Yes, the computer needs to be running. It is powered by the PC and to my knowledge has no internal memory for independent operation , so if it's off it can't send commands.

I don't think so. I think it requires power to operate, but I haven't tried this.

It is powered by the USB port on your computer. There is no AC connection to worry about.

It needs phantom power. If your system doesn't have phantom power you can ad a phantom power unit. There are some available on amazon.

Yes, it does require electricity so it is totally worthless if your power goes out.
