USB PD charging that allows you to use the charging dock?

My line of work requires that I always have a fully charged phone, and my current setup (an Anker 60 watt USB hub connected to the 12v port) just isn't keeping my iPhone (11 Pro Max) charged as fully as I need.

I really want to take advantage of 18w charging via USB PD, but would really like to keep using the charging dock in the car, which requires a 90 degree USB to lightning cable. I tried using an adapter (pictured below) to go from USB C to USB A (female) to allow me to keep using the Tesla provided cable, but it provides a negative charge rate. Any tips?

It won't work unless some 3rd party company like Anker makes an Apple MFI certified 90 degree cable that allows for PD. There's a proprietary design in the connector that tells the phone that the cable is capable/certified to allow for PD.

Apple themselves will never make a 90 degree cable. And they've only licensed out the tech recently to some 3rd party manufacturers.

so i ended up using the tutorials floating around to dismantle the center console and route a USB-C quick charger from the auto-port to the front so I could get 5A of charge. can you do the same, except use a USB-C to lightning cable?

Interesting! That explains why even using an Apple sourced USB to lightning cable, that setup didn’t work.

That’s the exact set up that I have now, the problem is that I can’t use USB C with the provided right angle cables from Tesla, which I really want to keep so that I can dock my phone.

Welcome to the world of charging via PD standard. The dependence on the C type port is a PITA. Its very finicky about adapters as well. I have a cable hanging out of my center console to handle quick charging. I use this one and it quick charges my Pixel 3 fine with a regular USB for my work phone or passenger.

that's basically the charger that i have. the charger isn't the problem for OP, it's the cable.

USB A took you back down to basic charging. But that should still charge your phone. Get the Anker USB C PD to Apple cable for faster charging.

But if you really need to be available by phone, start uninstalling apps or get a basic flip phone. If a standard charger is "negative" then your phone is sucking way too much power.
