Tether Tools CRN5A Coupler for Nikon EN-EL14A

This coupler connects a Nikon camera using the EN-EL14A battery to the Tether Tools Case Relay Camera Power System. It draws continuous power from an external 5V USB battery pack or wall adapter. The unit is designed for time-lapse photography, photo booths, video production and extended LiveView sessions. It contains no internal battery and cannot store a charge.

Check camera battery type and Case Relay ownership

Verify that your camera accepts the EN-EL14A battery form factor before ordering. The coupler only functions when paired with the separate Case Relay Camera Power System (CPS). You must also have a compatible 5V USB power bank or mains adapter to supply the system. Without the CPS and an external power source, the coupler cannot operate.

Replaces single EN-EL14A battery for mains

The coupler swaps out a standard EN-EL14A battery to enable unlimited runtime from wall power or USB banks. The jump is worth it when shoots exceed a single battery charge or when hot-swapping power banks is required for continuous operation. It is not for photographers who rely solely on internal batteries or who do not own the Case Relay CPS.

Questions about this item

Does the CRN5A coupler come with a USB battery pack or wall adapter, or do I buy those separately?

The coupler itself contains no battery and holds no charge; it requires the separate Case Relay Camera Power System and an external 5 V USB power bank or wall supply to deliver continuous power.

Is the CRN5A the only coupler I need for a Nikon body that takes an EN-EL14A battery?

Yes, the CRN5A is designed specifically for cameras using the EN-EL14A battery and fits directly into that battery port when paired with the Case Relay CPS.

How does the CRN5A provide uninterrupted power during a long time-lapse or video shoot?

Insert the coupler into the camera battery port, connect it to the Case Relay CPS, and hot-swap USB power banks as needed so the camera never loses power.
