I can't say I'm a fan of USB power socket outlets.
- Firstly they become part of the house permanent wiring, constantly drawing standby current
*, multiplied by how many room outlets?
- Secondly, they restrict insulation testing of the house wiring installation (without going around and disconnecting and looping out each one).
- Thirdly there has to be an to increased fire risk as socket quality and dodgy knock-offs fakes falls off the cliff to lowest cost. Not to mention spurious RCD tripping on circuits (with fridges, freezers etc) when one goes rougue.
- Fourthly, ncreased replacement cost - by an Electrician for most consumers / countries.
The idea of installing USB wiring around the house, presumably from some master PSU, with multiple outputs in the case of USB-C (you don't want all of your 5V devices getting hit with higher USB voltages when one device requests them), seems like a non starter to me. The cable csa needed to maintain USB voltage tolerance specs at low voltage and high current just doesn't sound economical.
Far better to have a nice rugged mains outlet and plug format (
), capable of supporting a modern plug top adapter that can be plugged in and removed as required.
