Overview

The Tether Tools TetherBoost USB-D/C Power Cable (TBDCUSB-2) is a specialized accessory designed for photographers who use the TetherBoost system during tethered shooting sessions. The TetherBoost itself is an inline signal booster that maintains reliable data transfer between a camera and computer over longer cable runs, but it requires external power to operate. This 1-meter cable provides that power by connecting the TetherBoost's D/C input port to the USB output of an external battery pack, freeing photographers from the need for a nearby wall outlet.

This is particularly valuable for on-location and outdoor shoots where AC power is scarce or impractical. By pairing the TBDCUSB-2 with a standard USB battery pack — the same kind commonly used for charging phones — photographers can maintain a fully mobile tethered workflow. The cable carries power only, not data, so it works alongside your existing tethering cable rather than replacing it. At 1 meter in length, it is long enough to reach a battery pack clipped to a light stand or sitting on a nearby surface without adding unnecessary slack to the setup. It is a small, single-purpose cable, but for photographers committed to tethered shooting in the field, it fills an essential gap in the power chain.

  • Simple USB connection works with widely available battery packs and powered USB hubs.
  • Purpose-built connector fits the TetherBoost D/C port securely for reliable power delivery.

👎 Cons

  • 1-meter length may be too short if the battery pack is stored in a bag or belt pouch at a distance.
  • Only useful if you already own or plan to buy a TetherBoost unit — no standalone functionality.
  • Does not include a battery pack, which must be purchased separately.
