Authentic part manufactured by eufy.（European standard） AC Cable for NVR device. Powers the NVR device, transmitting and distributing alternating current.
The connector clicks in snugly with no wobble, and the cable length is just right for my setup under the desk. It's been running my NVR for three weeks straight without a single hiccup, so I'm glad I went with the genuine part instead of a cheap knockoff.
Finally found a proper European-standard cord that actually fits snugly into the NVR unit—no wobble, no loose connection. The length is just right for my setup, and it's been powering the system reliably for two weeks straight.
