Here are the detailed product specs and a professional‑style summary for the Tether Tools Relay Camera Coupler for Select Sony Cameras (model CRPW10AM):
Product Overview
The CRPW10AM Relay Camera Coupler is part of the Tether Tools Case Relay Camera Power System. It replaces the Sony AC‑PW10AM battery in compatible Sony cameras, allowing continuous power supply from external sources (USB / wall outlets etc.) without relying on the camera’s battery. The coupler itself has no battery—it acts as a pass‑through/adapter to let power from the Relay power system feed the camera.
Key Features
Directly plugs into the camera’s battery compartment, using the same form as the AC‑PW10AM dummy battery. Polyline Corp+26x7 Fotografia Profesjonalna+2
Provides uninterrupted power when used with the Case Relay Camera Power System. That means you can run long shoots, time‑lapses, video, or live view modes without worrying about battery depletion. Polyline Corp+26x7 Fotografia Profesjonalna+2
Supports “hot‑swapping” of external power source: if the external USB power or battery bank is changed, the system is designed so the camera keeps running without dropping power. Polyline Corp+1
Compatibility
The CRPW10AM is compatible with a range of Sony cameras that use the AC‑PW10AM power standard. Some of the supported models include:
Sony a100, a200, a230, a290, a300, a330, a350, a380, a390 Design Info+2fotografiarte.es+2
Sony a450, a500, a550, a560, a580 Design Info+1
Sony a700, a850, a900 Polyline Corp+2Design Info+2
Sony a57, a65, a77, a99 6x7 Fotografia Profesjonalna+1

Before use it’s important to verify your model matches AC‑PW10AM compatibility and that the camera door/trapdoor allows exit of the coupler cable without interfering with door closure. Polyline Corp+1
Technical Specs
| Spec | Details |
|---|---|
| Model Number | CRPW10AM Polyline Corp+2Design Info+2 |
| Designed For | Use with Sony AC‑PW10AM dummy battery standard, in cameras listed above Polyline Corp+2Design Info+2 |
| Cable Length | Approximately 10 inches / ~ 25.4 cm from the coupler to where it connects to the Relay power unit. Polyline Corp+2Design Info+2 |
| Do's | Insert into battery compartment; ensure battery door fully closes with cable exiting through camera’s rubber / trap door if available. Use with Case Relay Power System and compatible external power supply (5V USB or wall source). Polyline Corp |
| Don’ts / What It Is Not | It does not include a battery; it is not a backup battery itself. If external power is lost and no UPS in the power system is used, the camera will lose power. Also, output depends on the power system connected. Polyline Corp |
Benefits
Eliminates need for multiple spare AC‑PW10AM batteries for long shoots.
Enables continuous operation for demanding workflows (video, time‑lapse, field work).
Uses external, non‑proprietary power sources which are generally more accessible globally.
Increases flexibility: you can use large capacity USB power banks, AC adapters, or other external power with the Relay system.
Things to Watch Out For
The battery door must close fully over the inserted coupler cable; otherwise loose fit or exposure to the cable opening could affect safety or sealing. If not sealed, dust / moisture might enter. Polyline Corp
Using low current or low‑quality USB power supplies / banks might lead to voltage drop or unstable operation under load (especially when camera is under heavy draw).
Make sure the connector/shell matches exactly AC‑PW10AM standard so that fit is secure.
If using outdoors or in hot conditions, heat generation may be higher because there’s no internal battery in the coupler itself (unlike the Relay power pack).
If you like, I can also prepare marketing‑grade product copy for CRPW10AM, or compare it versus a couple of alternative dummy battery couplers so you can see trade‑offs.
