What devices typically use a 2.5mm plug instead of the more common 2.1mm?
While 2.1mm is the de facto standard for many astronomy accessories, some brands and device types, particularly certain models of powered USB hubs, focus controllers, and older CCD cameras, use the larger 2.5mm center pin for their power input. These cables are designed specifically to bridge that gap, allowing you to power those devices from a standard 2.1mm power source like a Pegasus Astro Powerbox or a deep-cycle battery distribution panel.
Can I use this 2.1mm to 2.5mm cable for my specific mount or camera?
You must first verify two things: the physical plug size and the required voltage/polarity of your device. This cable adapts the physical plug from 2.1mm to 2.5mm but does not alter the voltage or polarity. Always confirm your device requires a 2.5mm x 5.5mm plug and that the power source provides the correct voltage (e.g., 12V DC) and center-pin polarity (typically center-positive) specified by the device manufacturer.
Is the 5A rating on this power cable important for my setup?
The 5A rating is critical for safety and stability. Using an underrated cable for a high-current device can cause the cable to overheat or the voltage to drop, leading to equipment malfunction. This 5A cable ensures that devices like thermoelectric coolers (TECs) on cameras or robust dew heaters receive the consistent power they need to operate correctly throughout the night.
Why would I need a 1.5m cable for my telescope?
A 1.5m (5 feet) length is often ideal for managing cables on a German Equatorial Mount. It allows you to run the cable from a power hub on the mount saddle or dovetail bar up to a camera or focuser on the telescope, with enough slack to prevent pulling or snagging as the telescope slews across the sky to track an object like the Andromeda Galaxy (M31).
Will this cable work with my Pegasus Astro Pocket Powerbox?
Yes, this cable is designed to work perfectly with any power source that has a standard 2.1mm DC output port, including the entire line of Pegasus Astro Powerboxes. It allows you to power a 2.5mm device directly from one of the Powerbox's 12V outputs.
Does this pack include one or two cables?
This is a pack of two identical cables. Each cable is 1.5 meters long and adapts a 2.1mm male plug to a 2.5mm male plug.
