Snug fit on my old router's power port, no wiggle at all, and the 12V 2.7A output matches the original spec exactly. Cord's a bit short but honestly it reaches fine behind my desk.

The L-shaped plug is a lifesaver for my wall-mounted setup, it tucks in tight where a straight jack wouldn't fit. Output is a steady 12V and it barely gets warm after hours of use.

Snagged this as a spare for my router and it's been rock solid for a couple weeks now. The 2.7A output matches the original specs exactly, so no random reboots like I had with a cheaper one. Cable's a decent length too.
