Does this unit require AC power or can it be used without it?

This antenna needs to be plugged in to power the antenna to work properly. I don't get anything without the antenna being powered.

The amplifier comes with a usb cable, if your tv has a usb port it can get power from that, otherwise it comes with an ac adapter for power. You definitely need the amp plugged in and hooked up though if you want to get all the channels it can. In some areas, close to the transmit towers you may pick up some stations without the amp, but usually you will have to have it hooked up to get clear reception.

I never installed batteries but as I recall it needs them or the AC power to operate.

Unit requires 12VDC to operate. Any off the shelf 12VDC power supply or wall adapter rated 500mA or greater should be capable of powering the unit.

This unit is powered by a small wall-wart type AC adapter, it does not have the capability to use a battery.

No. It's powered by a small AC to DC adaptor. You do need to factor that into the installation.

It operates on 110-120 volt ac. Anything else would require an adapter not provided.

I would not attempt to use the unit without electricity. The unit works like a forced air heating system. You have the burner train and air is force through the flames to produce heat at the outlet.

This unit requires a power source. I would not purchase it. I have found better that would work for your application.

Note that there is no A/C power plug. They use batteries only for headphones and base unit.

Hello Jill, Thank you for your question. No, it does not have optional AC power. However, in our test, the battery indicator showed 79% battery life remaining after taking about 935 pictures. It is highly energy efficient. Kind Regards, Ross Kelson GadgetsGo.com 305-791-1101

Hi David, thanks for your interest in our products. Yes, our monitors require AC power for several reasons. The first is our products all have two spare (powered) USB ports for other USB devices, and these ports require AC power. Next, our monitors also have HDMI input and this also requires AC power. Finally, our latest product, Monitor2Go FHD has speakers (for use with HDMI) which requires AC power too. I hope this is helpful. Please let us know if you have any other questions and feel free to email us directly at contact@mmt2.com. Thanks!

it requires a DC power source. If you want to use AC power you will have to convert it to DC.

It does not require the use of the AC adapter, it will work without the AC adapter being plugged in. It will only work, however, as good as any non-powered USB hub, meaning, there would be a limit to the amount of power that can be used by the devices connected, some devices will require the additional power, that is the advantage of the additional AC Power source.
