Tether Tools CRCE5 coupler for Canon LP-E5 battery cavity with 1200 mAh backup

Tether Tools

Tether Tools Case Relay Camera Coupler CRCE5 Canon LP-E5 1200 mAh

SKU CH-RH67-9SWEK

A coupler that draws continuous 5 V USB or wall power into Canon LP-E5 cameras while a 1200 mAh backup cell allows hot-swapping without interruption

  • Continuous camera power from external 5V USB or wall sources
  • Works with Case Relay Camera Power System for seamless integration
  • Coupler fits battery cavity without holding charge, keeping setup lightweight
  • Secondary internal 1200 mAh battery provides reliable backup power
  • Hot-swap external batteries without interrupting camera operation

Continuous Power for Extended Shoots

The Tether Tools Case Relay Camera Coupler CRCE5 replaces a Canon LP-E5 battery inside the camera body and connects to the Case Relay Camera Power System. It draws continuous power from an external 5 V USB source or wall adapter so the camera never runs out of energy during long sessions.

Fits Battery Cavity and Frees the Charger

The coupler inserts directly into the camera’s LP-E5 slot and passes power through the Case Relay system without holding a charge itself. This keeps the rig lightweight and lets you hot-swap external USB battery packs without interrupting the shoot.

Replaces Single LP-E5 Batteries on Long Jobs

It upgrades from a standalone LP-E5 cell when a single charge cannot cover time-lapse, video production, photo-booth or LiveView work. The built-in 1200 mAh secondary cell provides backup power if the external source is disconnected. Not suited for photographers who only need a spare battery for short outings.

Questions about this item

How long will the built-in 1200 mAh backup keep the camera running if the USB source fails?

The internal 1200 mAh cell provides temporary backup power during hot-swaps or brief USB interruptions, but it is not sized for standalone shooting.

Does the coupler itself generate noticeable heat when the camera is powered continuously from USB all day?

The coupler is a passive insert without charging circuitry, so it adds virtually no heat; any warmth comes from the camera's own electronics.

What additional Tether Tools hardware is required before this coupler can deliver power to the camera?

You must already own the Case Relay Camera Power System and a 5 V USB battery pack or wall adapter to complete the power chain.
