[OT] Dual-Gang switched 13A + USB sockets
I need to partially rewire my apartment. I am tempted to replace some old
double-switched sockets with those that incorporate USB sockets.
How often do mains sockets typically need replacing 40-50 years maybe?
How often do USB power supply specs change (500mA, 1A, 2A, 3A, etc etc)
every 2 years maybe?
