Snug fit on my old router, no wiggle at all. The 12V 3.0A rating matches the original brick exactly, and the elbow jack tucks neatly behind the shelf. Runs cool even after hours plugged in.

The L-shaped elbow plug is honestly the best part, it fits flat against the wall behind my desk instead of sticking out. Cord's a decent length too and it runs cool after hours of use.

Snagged this as a backup for my router and it powers up instantly, no flickering or hum. The 3.0A output handles the load fine, and the 3.5mm tip fit snugly without any wobble.
