the product can be connected without power

The product converts the power from the battery of your car to regular 210/220 V like you get from an outlet in your home. So you can plug a laptop into it and power the laptop while in the car. If you use it while the car is not moving, you will risk draining the car battery and having to jump the car to get it started again. The product uses the power from the battery to do its work.

You must plug it into the cigarette lighter of your car to work and the car must have a good working fully charged battery in it. It will work with the car turned off as long as your car battery is fully charged. BUT it will in fact drain your car battery if you use it while the car is turned off for a long time. I have used it for up to 30 minutes to charge a cell phone, and I've used it for about 20 minutes to run my lap top, both times with the car turned off and I had a fairly new car battery but I would not go any longer than that and I would not use it with the car turned off if your car battery is not new or is not a high quality brand.

I assume your qeustion is if the product can be left connected while the car is off. I'd say yes, it will turn off I think. Although I haven't tried it. But in case the 12V port inthe car stays on it may drain the car battery since it has a fan that spins when connnected to power.

An AC/DC power cord is included and required, as well as a Wi-Fi connection.

Yes, you can. It's not safe unless you have it plugged into a UPS though, keep that in mind. If power cuts or dips you'll have to start over.

Correct. Will work without power. Has a manual switch as well. Great switch for the price.

It has a rj45 cable (network cable) that goes from the controller to the device. No power is needed.

The device uses an external power supply. If you have needs other than 110V, you'll have to supply you own.

Hi.The controller can be turned on without having it plugged in the USB cable. The rechargeable battery allows independent operation. Regards

Nope. It needs to be powered. I could only get one item at a time to work. If I had 2 or more things plugged in, it wouldn't work at all.

It can be physically connected to two devices at the same time but they are not Bluetooth equipped.

It does not require any power source other than the HDMI cables you're using.

Short answer is no. You could disconnect the power to it. I keep it hidden, but if the need arises, I can reach and hit the reconnect button.

I've never tried that, so I'm not sure. However, it has the ability to plug into an electrical outlet which I assume would give it the power to charge electronics on its own, without being connected to the computer. It might be worth checking with the manufacturer, if possible.

Yes it can be used plugged in. Also it can be used without being plugged in.

No power source is required.use the included usb cable to connect the hard drive to the computer.

No need to be connected to a power source as it has an internal non removable battery.

Should work as long as the device not being used is completely powered off.
