What is the benefit of a 5A rating on these 50cm DC cables?
A 5A rating ensures the cable can handle high-power devices like cooled CMOS cameras, dew heaters, and electronic focusers without overheating or causing a significant voltage drop. Standard, lower-amperage cables can starve these devices of power, leading to connection drops or inconsistent operation.
Will these 2.1mm to 2.1mm cables fit my ZWO or QHY camera?
Yes, the 2.1mm x 5.5mm center-positive barrel plug is the de facto standard for most astronomy equipment, including cameras from ZWO and QHY, electronic filter wheels, focusers, and power distribution boxes like the Pegasus Astro Pocket Powerbox series.
Are these 50cm cables long enough for my setup?
The 0.5m (1.6 feet) length is specifically chosen for "on-telescope" connections. It's perfect for linking a camera, focuser, or guide scope on the main optical tube to a power hub or controller mounted on the same dovetail plate, which helps to minimize cable drag and snags.
Can I use these cables to power my telescope mount?
While the 2.1mm plug fits some mounts, you must verify your mount's power requirements. If your mount draws less than 5A and uses a 2.1mm input, this cable will work. However, many larger mounts use a different, often threaded, connector for security.
Is this a pack of one or two 50cm cables?
This is a pack of two individual 50cm cables. This allows you to connect two separate devices right out of the box.
Will these cables work to connect a Pegasus Pocket Powerbox to my cooled camera on an 8" SCT?
Yes, this is an ideal use case. If you have a Pocket Powerbox mounted on the dovetail bar of your 8" SCT, the 50cm length is sufficient to reach the power input on a cooled camera or electronic focuser at the rear of the telescope without excessive slack.
