Review Summary

I have purchased numerous of these battery packs. I use them to power my lumix g85 and gx85 cameras with the dummy battery insert. I can run my cameras forever off of regular usb power banks. They do only last a few years, which is the case with any battery, the battery will wear out. All batteries do. Get this thing, and get your matching battery insert, you can look up the model for your camera on their website.

I was initially pleased with it and used it on a few night shoots with my D850 where it worked very well.. I had not used it for awhile and now it will not take a charge and continually shows a red light. The battery does not appear to be user replaceable. Expensive junk now. Grrr....

Very simple to use, very reliable. I usually have the tether powering the camera 8-12 hours at a time, zero issues.

Expensive for what it is, but it works perfectly for me. I use it to power my a7ii on a dedicated astrophotography setup. When combined with a Anker usb power bank, I can shoot for multiple nights even in cold temps without worrying about swapping batteries.

Failed entirely to take initial charge. RED led on forever. Doesn't appear to be any sort of quality control in place.

Great product for astro photography where you can't afford to lose power. Bought it to use with my D850.

I got this to do some extended time lapse photography and it worked perfectly on my Sony A7rII. wWth the Sony adaptor and a external power pack it worked perfectly.

This saved me from buying extra batteries and the inconvenience of have to change batteries while driving. I can use either a 20K power bank or 2.1A car lighter adapter to power the camera.

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. With the Case Relay CPS, you can focus on capturing the perfect shot, knowing your power needs are covered.
