PFC is required under EU law and is a good idea anyway from an efficiency and harmonic reduction POV. It doesn’t however establish or change startup currents.

PFC is required under EU law and is a good idea anyway from an efficiency and harmonic reduction POV. It doesn’t however establish or change startup currents. There’s sparking when you plug it in and there’s this which is like a small explosion. Either way the sparking is entirely avoidable as well with a trivial. Little startup circuit or a couple of NTCs. I’ve tried it on a sample of three chargers now (we have three MBPs in the house of differing ages and original chargers) and they all have it. I’ve got a Lamba 12v 5A unit here as well which isn’t much bigger with a chopped off IEC lead on it. Nothing when you plug it in at all.
