I’m trying to find a cord with a USB C female end leading to a Lightning male connection.

I haven’t been able to find one so far that I am confident will fit my use case. I’m looking to make a connection between the USB C male on a Square stand to the Lightning female port on a 9th generation iPad.

Ideally able to transfer both a charge and the relevant data. But the data is by far the most important part of the setup.

Any help is appreciated!

TechMatte USB C to Lightning Cable Adapter

Does not switch from 5V to 9V charging depending on USB-C orientation. Resets itself to 5V when iPhone is disconnected.

korllo PD 27W USB Type C to 8-Pin Adapter

Switches from 5V to 9V charging without issue. Fails to reset itself to 5V when iPhone is disconnected. The right angle connection does not leave enough clearance for a case.

meenova 30W/27W USB C to Lightning Adapter

Has issues switching from 5V to 9V charging. When the phone attempts to fast charge the adapter resets and reattempts in a loop. Only occasionally works correctly.

UYOUNG 2Pack USB C Female to Lightning Male Adapter

Has a delay in beginning to charge. Occasionally gets stuck in a reset loop. Lightning end tolerances are off.

AGVEE 2 Pack 4 inch 30W USB-C Female to Lightning Cable Adapter

USB-C Female connector is misaligned inside. Lightning end tolerances are off.

Occasionally gets stuck in a reset loop attempting to switch from 5V to 15V with iPad Mini 5.

This one is mostly OK. Build is all plastic so may not be durable. It gets stuck in a reset loop with some power adapters if the adapter is plugged into the phone while it's locked before being plugged into power. As long as it's plugged into power before being connected to the phone it works fine. It switches to 9V fast charging without issue regardless of orientation. Tolerances of both USB-C and Lightning appear to be fine.

I know that such adapters are against USB-IF and MFi specifications. Even so, USB-C to Lightning cables are active and I'd expect that someone has come up with a working one.

Jadebones 2 Pack USB-C Female to Lightning Male Adapter

The tolerances and build appear to be good. Seems to switch from 5V to 9V on iPhone X and 5V to 15V on iPad Mini 5 without issue. Orientation doesn't seem to hamper it. It works with both eMarked and non eMarked cables.

Unfortunately, it's no longer available for sale, at least as of Nov 3, 2024.
