Tether Tools has released the Case Relay Power System, which allows you to connect an external power source such as USB battery packs or AC power. When the external pack runs low on power, you can hot swap to another USB battery pack without losing power to your camera.
Here’s how it works:
Simply insert the Relay Camera Coupler directly into the camera battery port. Then attach the Relay Camera Coupler to the Case Relay Camera Power System and power your camera with any standard 5V USB external battery (commonly known as a portable USB charger, which you can get most anywhere) or an AC power source, such as a wall outlet or generator.
The Relay Camera Coupler combined with the Case Relay Camera Power System provides constant, uninterruptable power for your camera and is perfect for time-lapse photography, photo booths, video production and power-hungry LiveView shooting or any long day on the set. Need more power? Hot swap in another power bank and continue shooting while never losing power to your camera.
Check out the video below for an overview of the setup.
The Case Relay Camera Power System retails for $99.99. You can find it and related accessories here on Tether Tools’ website.
