Re: Eliminating radio interference from Apple charger

The other day I used one of those ultrasonic eyeglasses cleaning machines while I had my AirPods Pro in and they went crazy with static as long as I had the machine on.

That could also be because of the noise cancelling, where the microphones are "hearing" the ultrasonic frequencies and the headphones are trying to cancel them out.

This is most likely exactly the problem. It's very unlikely that an ultrasonic cleaner operating at a few kHz will cause interference on Bluetooth.

>But it really bothers me to buy 40€ product and I still need to fix it with component costing over 2€ Honestly doesn't surprise me. I hold the same kind of sentiment after spending $1200~ on a brand new iphone 14 pro max just to find that I had to buy the charger brick so I could plug it into a wall. Come on Apple. Eliminating QOL things doesn't just automatically equal improvement.

Probably like 98% of customers already have a USB power source of some kind, so that seems like a reasonable cut corner.

That's not analogous. Not including the charger in newer iPhones actually reduced e-waste for me personally. I have collected many charges over the years and don't need more. When a device fails or I trade it in - I keep the charger (as most people I would think).

Perhaps they should have made the charger optional... but completely agree overall with the decision not to include it.

Earlier quoted context omitted.

The device was ordered from Apple's website.

The issue could be coming from the AC-DC charger used with the MagSafe charger as well, maybe retest with an Apple charger?

The issue was confirmed with two separate MagSafe chargers and three or four separate AC/DC chargers. The lab test in the post was done using laboratory DC power supply powering a DC to USB converter.

Also if the interference didn't come from the disc side of charger then the issue wouldn't be resolved with ferrite bead on that end. If the issue was on the USB connector side then the bead should be placed there.

> Eliminating Radio Interference from Apple Charger Why not notify the FCC ?

The author holds a Finnish call sign, so it would be more appropriate the Finnish authorities (Traficom). That said, it's still a bad look on Apple's design or production engineering. I would expect a higher level of quality.

Not really, modern phones have fast charge capability that's been improving generation over generetion, so what happens is new chargers are bought to take advantage of that. The older gen chargers are E-waste either way, and apple gets to charge us for something they should have included.

I would agree that its fine to not include it, had they not switched to usb-c right when they stopped including bricks so all my new devices came with usb-c chargers but I only have usb-a bricks

This thread looks like a relevant one to mention an issue with the Mac Studio that causes large inrush currents when you plug it in. The power connector arcs badly enough to trip a domestic 30mA RCD, it's reproducable with several units and on different electrical circuits at both home and office.

Not that I endorse cutting more corners, but I personally gave away the 30w dual USBC charger that came with my MacBook Air since I already own plenty of higher powered ones that work with other devices like my work MBP and Nintendo Switch etc.

I think it'd be great if Apple offered a small discount for opting out of unnecessary items.

I don't know the percentage of course, but I think you'll agree that at least part of the client base will simply reuse their existing charger.
