Many thanks

Hi,
I salute you for considering the load on wiring. As standard in caravans the wire size for 12V lighting wiring will be a minimum of 1mm CSA which has a rated current capacity of 8.75A. Some manufactures have used 1.5mm CSA which has a rated current capacity of 12.75A.
Without knowing exactly how many lamps are on the circuit I can't be certain how much spare capacity the wiring would have if all the lights were on at the same time, but in reality we rarely use all of them together so it's quite likely you could fit the usb's, especially if your lighting uses Led lamps.
Ultimately even if you did put too much load on the circuit, it's fuse or circuit breaker should
blow operate and protect the wiring.
