Compact Desktop Power Grommet

The Jgstkcity 3.15 inch recessed power grommet mounts flush in a standard round cutout to deliver two AC outlets and eight USB ports directly on the work surface. It suits home offices, hot-desking stations and retail counters that need permanent, low-profile power access without trailing adaptors. The unit accepts 100V-240V input and is rated at 125V, 12A for the AC sockets.

Installation Requirements And Freed Space

A 3.15-inch round hole and 3 inches of clearance beneath the surface are required; the 3.55-inch bezel sits 0.1-inch thick above the desktop. A 6ft cord connects the grommet to the mains supply, removing the need for separate wall-wart chargers and freeing the desk area for monitors, documents or tools. The flange width needed under the counter matches the 3.15-inch cutout.

Sustained Charging Behaviour

Each USB-C port provides PD 20W (5V/3A; 9V/2A max) and each USB-A port delivers QC3.0 20W (5V/3A max) when used alone. When both left and right USB-C ports operate together they share a combined 40W output (20W + 20W). The USB input draws up to 1.5A at 50/60Hz, maintaining stable delivery during extended multi-device charging sessions.

Questions about this item

Will the 12 A AC circuit hold up if I run both outlets and all USB ports at full load for hours?

The unit is rated at 12 A and 125 V, so the combined draw of the two AC outlets plus the 40 W USB maximum must stay within that 12 A limit; sustained loads near the rating will trip the internal breaker.

How warm does the grommet get and is there any fan noise when every port is charging all day?

No fan is fitted; the aluminium bezel acts as a passive heatsink, so the surface becomes warm but not hot during continuous 40 W USB charging, and operation is silent.

My desk is 25 mm thick — will the 3.15 inch cut-out and 3 inch under-counter depth fit without extra parts?

The grommet needs a 3.15 inch round hole and 3 inches of clear depth below the surface; a 25 mm top leaves ample room, and the 0.1 inch flange seats flush with no additional hardware.
