Tether Tools Case Relay Reviews

Used It Once, Then It Didn't Work Again

By Patrick
Rated 1 out of 5
Date: 2021-01-05

I bought this with the intention of using it for time lapses with my various Sony cameras. It worked fine the first time I used it, powering an a6000 from a USB power pack for a few hours with no issues. The unique feature of having a battery in line so that you can swap USB packs/sources is a great feature, and what led me to choosing this option. Then I didn't use it for a while - probably a few years. It sat in the drawer all that time. Then I went to use it again, and it's dead. It just shows as charging (the internal battery) forever and will not power on a camera. Attempts to contact the company via e-mail about it came up empty. So now I have a piece of e-waste that is completely useless to me and money wasted. For the money I paid I expected it to last for years and years to come. Not so much.

Fantastic solution to SLR camera batteries while videoing

By Murray

When live-streaming with my Sony camera, changing camera batteries every 30 min wasn't workable. This is the SOLUTION. Of course, you will need a fake battery for your camera that attaches to the Case Relay Power System. I get PERFECT, instant power, and I never have to worry about batteries again while I am on-line doing virtual presentations. LOVE IT!

Works great, but it has an issue on the Nikon D850

By Justin

The power system works great on my Sony A6500 and Nikon D750. Unfortunately, I experienced issues on my Nikon D850 with the camera intermittently resetting as if the Case Relay was not providing the appropriate power. After much troubleshooting, I determined the issue only occurred using the viewfinder and not in video mode or live view. Then, I determined that the Case Relay would drop power to the camera when the metering system would enter standby (default 6 sec.). Once I changed the metering standby timer to infinity, the problem was resolved. I would give this product five stars, but I wish Tether Tools would provide guidance to D850 users to overcome this simple issue. My hope is that this post will help save others' time if they experience a similar issue.

Love it!

I use the case relay to power my Sony A7RII while Im shooting a timelapse. Even when the camera shows the low battery warning the camera keeps running. I did some really long timelapses with it. The battery of the camera only let me record a 3 hours timelapse, but with the case relay there is no limit. The longest timelapse I did had about 8 hours, but I know that with this product Im able to do a 24 hours timelapse very easily.

Great for Night Photography

By Richard
Rated 5 out of 5
Date: 2018-12-30

I do a lot of night photography that includes meteor showers, time-lapse, and eclipse tracking. Changing batteries means lost frames, missed meteors, etc. For years, I have used DIY external battery solutions where I bought the components and soldered them together. This product makes that unnecessary. This is well thought out and allows hot-swapping of external phone chargers to keep the camera running. A typical 10,000 mAh battery pack will run the camera all night.

So far, these work really well. No issues yet. Haven’t gotten a chance to extensively test it out, as my last start shoot was cut short due to clouds and smoke in the air.

How much does this item weigh?
Asked by: Tyler
Not sure of actual weight. It's not very heavy or large. The battery pack you hook up to it will likely weigh more
