  • 12V Car Charger 5.5/2.5 mm DC plug

    This 12V Car Charger provides a simple and essential solution for powering your astronomical equipment in the field. It converts your vehicle's standard 12V automotive port into a usable power source, terminating in a 5.5mm x 2.5mm DC plug common to many telescope mounts and astronomy cameras.

    Reliable 12V Field Power with a 5.5/2.5mm DC Plug

    Stop worrying about the lifespan of portable batteries and power your entire imaging session directly from your vehicle. This cable is the critical link between your car battery and your gear, ensuring a steady 12V supply for consistent mount tracking and camera operation throughout the night. Its robust construction is designed for repeated use in outdoor environments.

    • Standard Automotive Plug: Connects to any standard car cigarette lighter or 12V accessory socket.
    • 5.5mm x 2.5mm DC Connector: The correct size for many popular mounts from iOptron, Celestron, and Sky-Watcher, among other astro-devices. Always verify your equipment's power port size before purchase.
    • Field Observing Essential: An indispensable accessory for anyone traveling to dark sky sites away from AC power grids.

  • What kind of astronomy equipment can I power with this 12V Car Charger?

    This charger is designed for any astronomical device that requires a 12V DC input and uses a 5.5mm x 2.5mm center-positive plug. This commonly includes many computerized GoTo telescope mounts, dedicated astronomy cameras, and other accessories. Always check your device's manual for its specific power requirements.

    Is the 5.5/2.5mm DC plug a common size for telescope mounts?

    Yes, the 5.5mm outer diameter and 2.5mm inner pin diameter is a very common standard for DC power input on telescope mounts from major brands like iOptron, Sky-Watcher, and Celestron. However, some devices use a similar-looking 5.5mm x 2.1mm plug, so it is crucial to confirm the exact size your equipment requires.

    How can I power my iOptron GEM45 mount in the field with this 12V Car Charger?

    The iOptron GEM45 mount uses a 5.5mm x 2.5mm DC input jack, making this car charger a perfect match. Simply plug the charger into your car's 12V accessory port and connect the DC plug to the power input on the mount's main control panel to provide stable power for GoTo slewing and tracking.

    Will this 12V Car Charger work with my Celestron AVX mount?

    No. While this charger provides the correct voltage, Celestron mounts like the Advanced VX (AVX) use a threaded DC power connector for a more secure connection, not a standard slip-fit 5.5mm plug. You would need a Celestron-specific car battery adapter for that mount.

    What's the advantage of using this 12V Car Charger over a portable battery pack?

    The primary advantage is virtually unlimited runtime. A car battery has a much larger capacity than most portable astronomy power tanks, allowing you to run your equipment for an entire night or even multiple nights without fear of the power dying. This is especially critical in cold weather, which can drastically reduce the effective capacity of smaller lithium-ion batteries.

    Can I use this 12V Car Charger with a device that needs a 5.5/2.1mm plug?

    No, it is not recommended. While the 2.5mm center pin plug might make intermittent contact inside a 2.1mm jack, the connection will be loose and unreliable. This can lead to sudden power loss to your mount or camera, potentially corrupting a file or ruining a long exposure. Always use a charger with the correctly sized plug for your device.
