Apple 20w charger issue?

[danpass]

I have an issue with TWO 20w chargers.

Neither my iPhone X or iPad mini 5 will charge off the charger.

They both recognize the charger but then cut off charging, yet they recognize it again. A constant cycle of hearing the ‘pong’ sound when the unit begins charging.

This is with aftermarket lightning to usbc cables which work fine with other chargers

with an apple-specific Lightning to usbc cable it seems to work smoothly.

why the difference?

Are your aftermarket cables MFi certified?

Like I posted months ago. I had 2 Cisco access points, and only bought one power brick as I was going to do POE with one of them, and changed my mind midstream. I looked at the official block, and noticed it looked exactly like another power brick I had from an older (non-Cisco) AP that had failed, so I used both the new one, and than one. (The output was the same, and they looked identical, except for the Cisco sticker.

And the AP that had the 'muggle' power supply filled its logs with 'This is not a Cisco supplied power supply', over and over again. It knew, the danged thing, but kept working for over a year. I just had to swim through the logs for any notices that I needed to see. Stupid, but I'm sure it sold more power supplies. I wonder if it freaked out running on POE. 'This is not a Cisco supplied POE power source!'...

I'm so sick of failed standards and proprietary pissings... Good grief. I don't miss working in the IT industry. The finger pointing that happened some days was so maddening. And the ridiculous stories I could tell...

Was this a standard 2-pin power cable? How would it even know if the voltage was correct? That's insane.

Still, this is nothing compared to the drama of SFPs. We've had network switches stop accepting third party SFPs after a software update. Imagine, your whole network breaking after working perfectly before because you installed an update on the switch which disabled third party SFPs, and of course no mention of it in the release notes. And the vendor won't help you because they don't support third party SFPs, even though both theirs and the third party are identical except for a few bits in the EEPROM.

why the difference?

Handling such 'high voltage' (high wattage) requires special Apple cables, with their blessing chips embedded. It's all I got...

It seems that with every 'new thing' there is less interoperability, and more times we are hogtied with proprietary nonsense. Why doesn't it work? Apple needs to sell cables.

Yikes...

Memories of the first switches that came out. I had a client that had a mix of a couple different brands, and we installed an HP switch in their backbone, and discovered that some of the switches either stopped working, or the throughput was slashed to unusable speeds. They swapped the worst performers with HP ones, and problems disappeared. I was so disgusted. I railed at the support person, and I guess enough others did as they updated the firmware, and the interoperability problem disappeared. Either it was stupidity, or ego, but they relented. Imagine a highway that you have to drive only Ford vehicles on. WTH!?!?!

EDIT: Actually it was hubs communicating through the switch. I replaced the cables, and all the other troubleshooting things to do, and kept wondering how the damn switch knew what it was communicating with. It made no sense, yet if I swapped my personal hub in, it worked. Weird. If that starts up again, it's going to be a holy hot mess...

Aukey has had their problems lately. Apparently they got kicked off of Amazon for trying to manipulate their reviews.

If they'd pull that, perhaps they started leaving out (or counterfeiting) the "blessing chip" (nice one @PinkyMacGodess) after initially passing MFi certification.
