Tether Tools Power Management

Tether Tools offers a range of smart solutions that provide extended battery power on-location and in the studio. When shooting time-lapse, filming or astro photography, a battery change can be disastrous and ruin several hours of work. With the Tether Tools ONsite Relay C Camera Power System, you can power your camera directly from a wall outlet or via an external battery.

Tether Tools ONsite Relay C Camera Power System

External power supply for your camera

Imagine shooting time-lapse, filming long sequences or creating powerful astrophotography sequences without ever having to worry about annoying interruptions due to the camera's battery running out!

With the Tether Tools ONsite Camera Power System, you can connect the camera to an external power supply and provide the camera with "forever" power. You can even switch between different power sources seamlessly thanks to ONsite Relay C having dual USB-C connections!

  • Never interrupt for changing the camera battery
  • Avoid purchasing expensive extra batteries for the camera
  • Fits most camera models USB-C connection to power source

The ONsite Relay battery adapter is available for most camera brands and models. In combination with the ONsite Relay C Camera Power System, you can replace the camera's original battery with an external power source that never runs out.

Battery adapter suitable for most camera models

The Tether Tools Relay battery adapter is available in different versions to suit most camera models on the market. The adapter fits into the camera's regular battery compartment and thus replaces the need for expensive extra batteries for the camera.

The power adapter that can be connected to battery or wall adapter

The ONsite Relay C Camera Power system is placed between the battery adapter and external power source. Via its two connections equipped with USB-C connectors, a large number of external battery sources, or wall sockets via USB-C adapter, can be connected to your camera to supply power to your camera and eliminate the stress that a dying camera battery can create. With the two USB-C connections, you can alternately change the power source, so if a connected power bank starts to fail, you can in good time connect a second power bank or wall socket in parallel and let the photography continue without interruption.

Power bank or wall adapter?

Why choose? Choose the power source that best suits the needs you have for your photography. Tether Tools offers very good power banks, batteries and USB-C wall adapters that fit perfectly into the ONsite Power System.

Complete your camera equipment with the Tether Tools ONsite Camera power System and give your subjects and photo assignments your full focus. You don't have to constantly monitor your camera's battery status and worry about ruining a film or photo assignment because the camera's battery has run out.
