I've been using the SYCON Adapter Outlet Extender for about a month now, and it's become my go-to solution for tight spaces. The compact design (seriously, it's barely wider than my thumb) makes it perfect behind my wall-mounted TV where regular plugs wouldn't fit.
What surprised me most was how sturdy the connection feels. When I plug in my phone charger or laptop adapter, there's no wobble - those brass terminals grip tight. I've even used it with my Raspberry Pi setup in the car (via an inverter), and it handled the load without getting warm.
The 90° orientation is genius for crowded areas. In my home office, it lets me use all four outlets without blocking adjacent sockets - something that drove me crazy with bulkier extenders. The fireproof PC material gives me peace of mind when charging multiple devices overnight.
Pro tip: Pay attention to the polarized slots if you're using sensitive electronics. I initially plugged mine in 'upside down' relative to product photos, but the sideways labeling makes orientation a non-issue once installed.
While I wish it had grounding capability (note: this is strictly 2-prong), for most of my daily charging needs, this little white brick has been a game-changer in optimizing outlet real estate.
