The core issue is that computer manufacturers, often in an attempt to be as efficient with power as possible, are either under-powering or dynamically-powering their USB 3.0 ports. These manufacturers are not currently considering the unique needs of photographers and this is causing these connectivity issues.
The TetherBoost Pro USB 3.0 Core Controller conditions the line and regulates the power from DSLR/Digital Backs to the computer, eliminating these limitations and allowing your tethered connection to operate up to full USB3 speeds for tethering connections from 15 to 65 feet without any loss in signal. The TetherBoost Pro also features the TrueConnect LED indicator which ensures signal connectivity between a photographer’s DSLR, Mirrorless or Digital Back camera and a computer.
The TetherBoost Pro USB 3.0 Core Controller can be used with or without external power and will facilitate producing a reliable connection either way. However, adding power to the line will reduce the customary drain on camera and computer batteries. The included USB DC cable is optional for adding a USB external battery pack (sold separately) or AC power (adapter included).
Tethering connections rely on power from your camera and/or computer to transfer images successfully. Read this helpful article to understand more: Why Does My Connection Fail?
JerkStopper Extension Lock
Included in the TetherBoost Pro Kit is a JerkStopper Extension Lock, an effective locking device that keeps cable ends protected from frustrating disconnects, damage, and electrical hazards. The simple clam-shell design enables you to close the JerkStopper Extension Lock around each end of the TetherBoost Pro and USB 3.0 cable, then twist to lock the cords securely and safely together. The JerkStopper Extension Lock comes with two included rubber washers that waterproof your connection, further protecting your connection and holding the cable in place.
*Please note the purchase of the TetherBoost Pro USB 3.0 Core Controller does not include an external battery pack. Please see our Rock Solid External Battery Pack. Additional accessories sold separately.
