Flying CX J class with CPAP
My partner and I will be flying CX J class LHR-HKG-SYD and AKL-HKG-LHR. We both use (REMstar Plus M series) CPAP's which are rated for rated for 100 – 240 VAC, 50/60 Hz. CX says their outlets are 115v (which is fine) 400 Hz. I am a bit worried about the 400 Hz. Does anyone know what this will do to my machine?
