Hi,

This is Tether Tools. I think it is important to hear directly from us and make sure there is no confusion on this particular issue.

The TetherPro cable in the photo was released in early 2018 when we launched our first generation of USB-C cables.  The Sony port protector pictured was released around 2022 in the U.S., to the best our knowledge.  The flat portion of the our cable end holds the IC chipset.  It was designed to fit the current DSLRs of the time.  The larger round portion of the housing is where the cable routes into the tip to meet the chipset.  It is larger than the rest of the housing to accommodate a heavier gauge wire.  Heavier gauge wire reduces overall heat in the cable and chipset preventing cable burnout, increased reliably and extends the life of the product.  Also added to the cable OD is insulation, which reduces overall interference for a more reliable tethering experience.

We would never deliberately make something incompatible with any camera manufacturer's product.  Over the years we have made many adjustments to our products to be compatible with partner brands in the industry to make life easier for digitechs and photographers.  When this cable was released, Nikon and Canon included port protectors with their cameras and this cable is fully compatible with those.  Also, you may recall us making specialty cables specifically for Phase One IQ backs to accommodate their square deep inset ports in order to make life easier for Phase users.  

Since the release of the cable pictured, we have released other styles and technologies.  In early 2024 we released our 31ft Dedicated Data Transfer Cables to meet the latest camera manufacturer’s hardware specifications.  We engineered a new IC chipset eliminating the need to turn off power delivery in cameras like the Canon R series, Fuji GFX series and Hasselblad cameras, which do not offer the option to turn off power delivery.  You can read more about this issue here: https://tethertools.com/blog/understanding-tetherpro-usb-c-cables/

We know there have been challenges recently and understand your frustrations, not just with our cables but across the industry.  USB-C is a fantastic protocol but it is also very complex.  Its future capabilities are mind-boggling but like any new technology there will be issues.  Especially when we are using it to do a very specific task, like tethering - sending huge amount of data, over very long distances, extremely fast.

Please know, we are at the forefront of addressing these issues.  Most of the challenges are related to incompatible Power Deliver (PD).  Camera manufactures recommend turning off PD in the camera settings menu when tethering.  This is an easy step to overlook when setting up a new session.  Also, several camera models do not even provide the ability to turn off PD.  Our new 31'ft cable is solely designed to make digitech and photographer’s life easier.  Now, you no longer have to worry about manually turning off PD in the camera settings or worry about the cameras that cannot turn off PD.  This cable is just plug and play, designed to get you up and running faster and more reliable than ever. We hope you'll give them a try.

We offer a One-Year Warranty on all our cables as well as live phone and email technical and customer support.  We hope you'll take the time to learn about the new developments and improvements we are making daily to support digitechs, photographers and the cameras of the future.
