For example, if you want to use a cooled CCD camera (that usually requires a lot of Amps) we advice you to select the 14A version. If you use a uncooled DSLR or mirrorless camera, you can use the 5A version. Let's see some example, considering maximum power consumption for every element connected and powered to the EAGLE:

Example setup 1 - low power consumption system

• EAGLE: maximum power consumption 1A (average power consumption: 0.6A)
• Uncooled DSLR camera: power consumption 0 (powered from internal battery of the camera)
• SkyWatcher AZ-EQ6 SynScan mount: maximum power consumption 3A (average power consumption: 1A)
• Guide camera QHY5L-II mono: power consumption 0 (powered from EAGLE USB port) 

Total maximum power consumption: 4A. For this system we suggest you the 5A power adapter.

Example setup 2 - high power consumption system

• EAGLE: maximum power consumption 1A (average power consumption: 0.6A)
• Cooled CCD camera: maximum power consumption 4A (average power consumption: 3A)
• SkyWatcher AZ-EQ6 SynScan mount: maximum power consumption 3A (average power consumption: 1A)
• Guide camera QHY5L-II mono: power consumption 0 (powered from EAGLE USB port)
• Dew heater: power consumption 1A (powered from EAGLE dew heater port)

Total maximum power consumption: 9A. For this system we suggest you the 14A power adapter.
