Tether Tools Case Relay Camera Power System is the first infinite hot-swappable power source for time-lapse photography, power-hungry LiveView shooting or video production. It offers uninterruptible power to most DSLR and Mirrorless cameras via any common USB 5V power pack or wall power.
Case Relay meets the demands of filmmakers and photographers for whom consistent camera uptime is critical. Case Relay connects directly to any USB 5V battery, commonly used to charge smartphones and tablets.
The Relay contains a secondary 1,200 mAh internal charge allowing you to swap out power sources mid-shoot and maintain 100% uptime. This back-up power separates it from all other external power solutions on the market,
Case Relay is compatible with many Sony, Canon, Nikon and Panasonic cameras and can be powered by any 2.1+amp 5V USB power bank and/or USB Wall Adapter.
Tether Tools Relay Camera Coupler is required for the camera being powered with Case Relay.
How does it work?
A Relay Camera Coupler is inserted directly into their camera battery port, then connected to Case Relay CPS. The Case Relay connects directly to any standard 5V external battery (commonly known as a portable USB charger, widely available at most stores or via TetherTools.com) or an AC power source, such as a wall outlet or generator.
With Case Relay’s own secondary, internal 1200 mAh battery, if the photographer’s external battery pack runs low it’s easy to hot swap the external battery and not lose power to the camera. With the new Rock Solid External Battery Pack (10,000 mAh) from Tether Tools, photographers will be able to shoot considerably longer than with a standard camera battery. A 10,000 mAh external battery will provide 3-10 times the power of most camera batteries, depending on the camera.
When access to AC wall power is convenient, simply plug the Case Relay cable into an AC Wall Adapter (sold separately) for an infinite power source. (USB Active Extensions can be used for added distance)

But wouldn’t this make the camera even more susceptible to water/dust damage?
Not at all. If you look closely at the a7 series camera’s battery door there is a small slot to feed the cord can though. Bet ya missed that… 😉
Nice power system, it was already possible using the micro USB port on the A7SII and other Sony dslr but the battery dummy connected to a USB cable is great!
Expect that powering through the Multi Terminal port only works on a7RII, a7SII and a6300 and using the Multi Terminal port to power the camera means you can’t tether or use a wired remote or intervalometer.
Will this work for a7II?
It works on ALL Sony mirrorless cameras that use a NP-FW50 Battery.
What about these items from your previous post – https://briansmith.com/external-battery-sony-a7-a7r-a7s-ii/ – I am seriously looking at this for a timelapse session in April. I have lots of Canon Batteries but the ease to use the USB power supplies intrigue me. Advice please.
IndiPRO Power Grid might make sense of you already own a bunch of Canon Batteries that you want to put to use. Otherwise I like this better.
