The Tether Tools Air Direct DC to USB Power Cable (ADC-DCUSB) is an accessory designed to provide continuous power to the Air Direct Wireless Tethering System. It connects the Air Direct device to an external power source, such as a USB battery pack or a wall outlet with a USB adapter, allowing for long-term use without relying on the included LP-E6 battery. 🔋
Key Features & Use
The primary function of this cable is to supply constant power to the Air Direct, preventing interruptions during a tethered shooting session. This is especially useful for photographers who need to shoot for extended periods, like in a studio setting. 📸
Power Source: It has a DC plug on one end that connects to the Air Direct and a USB-A plug on the other for connecting to a power source.
Uninterrupted Workflow: The cable allows you to hot-swap the LP-E6 battery on the Air Direct device without losing your tethered connection, ensuring a seamless workflow.
Length: The cable is approximately 3.25 feet (1 meter) long with a right-angled DC plug.
Note: This cable is for powering the Air Direct only; it does not charge the LP-E6 battery.

Compatibility
The ADC-DCUSB cable is compatible only with the Tether Tools Air Direct Wireless Tethering System. It is a replacement or supplementary cable for the one that comes with the Air Direct kit. The cable itself does not directly connect to a camera.
