Tether Tools Case Relay Camera Power System 1200 mAh 7.4 V

SKU CH-JSQ8-AS4F3

Continuous camera power via any 5 V USB source with a 1200 mAh 7.4 V UPS buffer, compatible with most major brands

  • Continuous shooting via external 5 V power bank
  • Uninterrupted power during swaps from built-in 1200 mAh 7.4 V UPS
  • One coupler fits most Canon Nikon Sony Panasonic Fuji Olympus
  • Replaces costly proprietary cells with standard USB input
  • DC 8 V 2 A output drives camera without battery changes

Uninterrupted Camera Power

The Tether Tools Case Relay system delivers continuous power to compatible Canon, Nikon, Sony, Panasonic, Fuji and Olympus cameras from any 5 V USB source. An internal 1200 mAh 7.4 V lithium battery acts as a UPS so the camera stays on while you swap external packs. A Relay Camera Coupler specific to your camera model is required and sold separately.

Suits Long Shoots And Studio Work

Videographers, time-lapse creators and studio photographers who need hours of runtime without changing proprietary batteries will benefit. The system accepts common 5 V 2 A USB power banks or AC adapters, eliminating the cost and hassle of multiple OEM cells. It is not for shooters who cannot buy the matching coupler or who need a fully self-contained battery with no external pack.

1200 mAh UPS Bridge Capacity

The built-in 1200 mAh 7.4 V battery provides enough reserve to keep the camera running during a hot-swap of the external USB power source. It is not designed to power the camera for extended periods on its own; runtime beyond the bridge moment depends entirely on the capacity of the external 5 V pack you connect. Output is rated at 8 V maximum 2 A.

Questions about this item

Do I need a specific Relay Camera Coupler for my camera model to make this work?

Yes, a Relay Camera Coupler matching your camera model is required and sold separately; the unit cannot power the camera without it.

Can I keep using my existing proprietary camera batteries while the Case Relay is connected?

The system replaces the proprietary battery with the coupler, so the original battery is removed; you power the camera from any 5 V USB source instead.

How do I confirm the internal UPS battery is keeping the camera alive when I swap external packs?

The 1200 mAh 7.4 V UPS battery maintains power during the swap, so the camera stays on without interruption while you change the external 5 V source.
