About this item

Bring uninterrupted power to your photography sessions with the Relay Camera Coupler, a key component in the innovative Case Relay Camera Power System. Designed for the modern photographer who demands both reliability and flexibility in their equipment, this coupler is the ultimate power solution for a wide array of cameras.

Crafted with durability in mind, the Relay Camera Coupler is a high-quality, compact insert that fits seamlessly into your camera's battery cavity. By connecting to the Case Relay Camera Power System, it enables your camera to draw power directly from an external 5V USB battery pack or wall power source, ensuring that you never miss a shot due to a depleted battery.

This convenient and reliable accessory is essential for photographers specializing in time-lapse photography, photo booths, video production, and extensive LiveView shooting. Its compatibility with a diverse range of camera models makes it a versatile choice for professionals who require consistent performance across different equipment.

The Relay Camera Coupler does not contain a battery nor does it hold a charge on its own. Instead, it acts as a conduit for power, allowing for continuous camera operation. When paired with the Case Relay Camera Power System, it offers an infinite power solution that is perfect for long shooting days or demanding projects.

How does it work? Simply insert the Relay Camera Coupler into your camera's battery port and connect it to the Case Relay CPS. Power your camera with the included Rock Solid External Battery Pack, or an AC power source using a USB to AC wall adapter. Alternatively, you can use the ONsite D-Tap Battery with V-Mount for even more flexibility.

The ingenuity of the Case Relay Camera Power System also includes a secondary internal 1200 mAh battery. This means that if your external battery starts to run low, you can hot swap it with another power bank without ever interrupting the power supply to your camera.

Experience the freedom and peace of mind that comes with knowing your camera will stay powered through the most critical moments. The Relay Camera Coupler, in conjunction with the Case Relay Camera Power System, is the professional's choice for sustained power delivery and exceptional performance.
