Product overview 1.20AWG power cord, 1 m long, with a 5.5 x 2.1 mm elbow plug on one end and a 5.5 x 2.5 mm straight plug on the other. Both ends support output and input function, so either end can serve as the power input or output as needed. Key benefits Compatibility: adapts between two common DC barrel sizes (5.5 x 2.1 mm and 5.5 x 2.5 mm) so you can use one cable to connect devices and power supplies with different jack types. Reliable power delivery: 1.20AWG conductor supports stable current flow for typical consumer and smallindustrial devices. Durable and flexible: PVC jacket resists bending and is designed not to break easily, reducing the chance of failure at stress points. Spacesaving connector: the elbow (rightangle) plug reduces strain and saves space in tight installations while the straight end provides a secure, conventional connection. Practical attributes Function: bothend input/output capability for flexible wiring and quick swap of source and load. Compatibility: suitable for energy storage power supplies, laptops, routers, surveillance cameras, and similar DCpowered equipment. Size and form factor: 1 m length for convenient reach; 5.5 x 2.1 mm to 5.5 x 2.5 mm conversion covers common device jack variations. Material and performance: PVCjacketed cable built to resist repeated bending and reduce breakage risk. Typical applications 1. Connecting a surveillance camera to an energy storage power supply where the camera and battery pack use different barrelpin sizes. 2. Adapting a router or laptop power adapter with a 5.5 x 2.1 mm plug to a device requiring a 5.5 x 2.5 mm jack, or vice versa. 3. Replacing a damaged power lead or providing a temporary adapter in field service and maintenance work where quick, reliable power connections are needed. Why choose this cable Simple, reliable adapter cable that avoids the need for power supplies or cumbersome converters. Built with thicker conductor and a flexible PVC jacket to handle everyday routing and installation demands.
