Pegasus Pack of 4 x 2.1 to 2.1 Cables

These cables are primarily used to connect 12V DC powered astronomy accessories to a central power distribution unit. Common uses include powering cooled astronomy cameras, electronic filter wheels, motorized focusers, dew heater strips, and flat field panels from devices like the Pegasus Astro Pocket Powerbox series or the ZWO ASIAIR.

A 5A rating is sufficient for most individual pieces of astronomy gear. For example, a cooled CMOS camera might draw 2-3A when the cooler is at 100%, and a focuser motor draws very little. This rating ensures a safe margin for high-draw devices. Always check your specific device's power requirements, but a 5A cable is a robust choice for nearly any single accessory on a telescope.

Yes, the ZWO ASIAIR Pro and Plus models use 2.1mm x 5.5mm output ports for powering accessories. These cables are fully compatible and are ideal for connecting your ZWO camera, EAF, or filter wheel to the ASIAIR's power outputs.

A modern astrophotography rig often has multiple powered devices. You might have a primary camera, a guide camera (if not USB powered), a motorized focuser, and a dew heater strip. This pack of four cables allows you to power a complete, multi-device imaging setup from a single power hub, making cable management cleaner and more organized.

Yes, the 2.1mm x 5.5mm barrel connector standard for astronomy equipment is center-pin positive. These cables maintain that standard polarity from end to end, ensuring safe and correct operation with your gear.

A 1-meter length is often the ideal "goldilocks" length for on-telescope cable management. It's long enough to run from a device mounted on the optical tube to a power box on the dovetail bar without being so long that it creates excessive loops that can easily snag on the mount during slewing.
