Review on 🔌 14" Ultra Low Profile Power Extension Cord Splitter Cable - 16 AWG, 2 NEMA 5-15R Outlets to 1 NEMA 5-15P Plug by Nadia Miller

I've bought these several times to use behind furniture that would otherwise be pushed against the wall. This solves the problem nicely, and the quality of the female connector is good enough to provide a decent transformer, which is handy considering how many things like clocks etc depend on a wall wart.
