Question 1

Can the power output of the radios be controlled?

Accepted Answer

Both bands 2.4 and 5.0 can be adjusted up and down. However I left mine at full strength to help penetrate walls and reach out. That's why purchased it in the first place. In fact I've been thinking about purchasing another one of these so I may set one up on both sides of the house. Getting a crisscross Wi-Fi signal is best to eliminate dead spots. And to reach further out front and back yards even more. I have found that the radius is not as great as advertised. Perhaps that's without walls will give you the 8000 sq. ft. Coverage. My lot is 50 x 1 50 with a 1500 ft.² house. I have placed mine in the center of the house high up. 
I had to turn my Wi-Fi router off due to a conflict with the amp wireless. My plan was originally to crisscross Wi-Fi. But for some reason it wouldn't work together with my router modem. Even though I changed channels to the other side of the spectrum. There was still clipping and dropping out the Wi-Fi light on mine Wi-Fi router modem. Perhaps purchasing another amp they might work together allow me to place them on opposite sides of the house.
One thing I have found I was unable to log into the amp on my network going through switches to do any setup. I had to hook it directly to my computer motherboard Nic card to allow me to set up all the functions, settings and security. Once I did that I was able to place it back into the center of the house and put it to use.  
Thus far I've been satisfied with this amp wireless high-power 700 mW dual band AC access point. Hope this helps you make a sound decision.

Question 2

can this be powered with power over Ethernet?

Accepted Answer

I don't see any reason why not, however, my setup is hardwired to my gigabit switch and I have no way off testing that configuration.

Question 3

Is this product CE rated?

Accepted Answer

Mine does not have a CE rating but mine is sold in the USA.  
To be sold in Europe it must have a CE rating.  So I am sure if he bought one for the European market it would.  He can call Amped Wireless. I tried to provide the phone number and website but you would not allow me to include it in my answer. If you are going to ship to Europe then you must offer products that are CE rated.  Mine is FCC rated which is the rating agency for USA.

Question 4

Do you desk top or lab top to connect to this devise?

Accepted Answer

It does not matter.  A computer is a computer.  You need to hardwire into a desktop or laptop to do the initial setup and you must turn off your WiFi during the setup process.  Then you disconnect from the computer, turn back your WiFi if you wish and hardwire the APA20 into an Internet connection.

This device provides WiFi out but must be hardwired for its input.
