DSLR cameras use lithium batteries that, during long-exposure astrophotography, can run out of charge and thus avoid you imaging the night sky. That's why we created these cables with voltage regulators and false batteries that allow you to power your camera directly from the EAGLE (also EAGLE Core) in place of the battery.
These Eagle-compatible power cables feature, on one side, the false battery that plugs into the DSLR in place of the standard battery. On the other side, they have the plug with a screw connection to prevent them from being accidentally disconnected from EAGLE. In the middle, there is a voltage regulator that converts the power to the voltage required by the selected camera.
