What sets the Case Relay Camera Power System (CPS) apart is its ability to provide continuous, uninterrupted power to your camera, ensuring you never miss a crucial shot due to battery failure. This innovative power solution is compatible with a broad spectrum of camera brands including Canon, Nikon, Sony, Panasonic, Fuji, and Olympus, making it a versatile choice for photographers and videographers alike. The Case Relay CPS works in conjunction with a Relay Camera Coupler (sold separately), which is inserted directly into the camera battery port. This system allows you to power your camera with any standard 5V external battery, also known as a portable Usb charger, or an Ac power source such as a wall outlet or generator. One of the standout features of the Case Relay CPS is its internal Ups battery. This secondary internal 1200 mAh battery ensures your camera remains powered even while you're swapping out external batteries. This feature is particularly beneficial for those long shooting days or during power-hungry LiveView shooting. For photographers and videographers involved in time-lapse photography, astro-photography, nature, fashion, landscape, architecture, or any extended shooting time, the Case Relay CPS is an ideal choice. It's also perfect for video production, as you can swap the External Battery Bank without having to stop shooting to change camera batteries. When connected to a Tether Tools Rock Solid External Battery Pack (10,000 mAh), you can shoot considerably longer than with your standard camera battery. A 10,000 mAh external battery provides 3-10 times the power of most camera batteries, depending on the camera. Need more power Simply hot swap in another power bank and continue shooting without losing power to your camera. The Case Relay Camera Power System is not just a power solution it's a tool that ensures consistent uptime, making it ideal for powering photo booths and other photography setups that require extended shooting time.
