There are three ways you can power this unit. The easiest is to do yourself would be to use the cigarette lighter plug adapter plugged directly into the port at the bottom of the screen. If you don't want a wire hanging from underneath the monitor you can use the same cigarette lighter plug and hook it up to one of the wires that goes into the seat via the headrest poles which will require you to open up the upholstery on the back of the seat to fish the wires through and make the connection there exiting the bottom of the seat. If you would like a more permanent install and not have to sacrifice your cigarette lighter outlet you can use the other included wiring harness and make two connections: black wire to vehicle ground, red wire to 12 volt switched power to shut off power when the key is off. If the seat you are putting the headrest in is a power or heated seat it will be easy to do with wiretaps and a multi-meter if you know what you are doing as the units draw very little power and have an inline fuse. From there you just want to make sure you have enough slack in the wires and can fully adjust the seat forward and back without putting any tension on the wiring. This unit is very simple to hook up in my opinion and if you are not comfortable doing it any reputable car audio or mechanic shop should be able to handle it and should only take 30-60 min per headrest depending on the vehicle. There are many youtube how-to videos on how to install these that can save you some money even if you just run the wires through the seat and would rather pay a shop to make the electrical connections for you if that is what worries you as this is what takes the majority of the time to install.

Cigarette lighter or you can hook directly to your battery. I have a cigarette lighter in my center console so I ran the power under the seats into center console to plug them in

it comes with a ciggie adapter however i got mine wired to the car, which means when ignition is on there's power to the unit, personally if you dont know crap about wiring like me, its best to get professional to do it for u, labour is a bit expensive but you get the unit install right, i paid $120(labour)for a dvd headunit+this 2 monitor, juz my 2cents, hope diz helps

The switch does need external power. I removed the switch when it defaulted and blew out the HDMI input on my TV. I wouldn't suggest using it--period! !!!!!

The cable gets power from USB (from the host PC). No problem if you use only Tx, Rx and GND.

Nope, its just electronics. Zero issues, but you wouldn't be able to power it (requires two outlets)

the usb port is for outgoing power, and as long as u have ur own cable, it'll power just like any other USB. very versatile device for 20$. =)

I have it plugged directly into the wall now, the power has gone out a few times and no data has been lost. I am thinking about getting a surge protector with a battery backup just in case.

It has it's own power supply so I have not had any problems with powering anything. Also, since it has a separate power supply, it charges things while the comp is turned off. I highly recommend this unit.

No problems so far but I would not use constant power to the unit due to constant battery drain. I would use a external power switch to control power.

Agree with Bruno. I only need to plug it in for power...wifi connection is wireless

It always needs external power. It has a 3.5" hard drive, whereas the one's that run only on USB have a 2.5" (laptop hard drive). That is the main difference.

No problem dude! Its powerd by the USB port! You dont have to plug it on the wall

Single USB connection. It does not draw power from the computer. It has a plug for external power. I don't like the external drives that draw their power from the computer.

Actually the manual does mention that an external power adapter is available if the attached device needs more power than the ExpressCard can supply. It's on page 2. Frankly, it seems to me, the vast majority of people will be better served by running the supplied USB 3.0 cable from the card to a powered USB 3.0 hub. This avoids any power issues in the first place.

Uses external power cord with transformer. Power supply will be a function of that power cord, not of the router.

No, I draws its power from the mother board. You may be thinking of USB hubs, which often require external power. Hope this helps.

That's what I've got it plugged into. Works great (for the power consumption - I only have a 300W supply)!

I only use a FireWire cable from my PC for power. Mine works fine that way.
