Did you have a Samsung phone? Hmm Same as part number above.. @cmarshack maybe open up your wireless charger and see if the shielding is there..
Update: Received Car Charger from Amazon, pretty cool little charger for those that just want a USB C car charger goes all the way into the port. Only annoying thing is the little blue light.. I ran the wire behind this little area (see photo) so it’s in line with the charger versus the provided track for normal items plugged into that spot. Allows the rubber to seat properly with no issues..
That is interesting because my Service Center had no idea what I was talking about. I will reference the part next time, thanks! 1546873-00-B I can only assume the B is a newer version and I must have the A.
Great write up. I just did this project today and a couple of observations: Works without a case or Apple's Silicone case (Haven't tried Apple Leather case yet) Does not work with the Nomad Magsafe Rugged Case. I would imagine, it's just too thick. I ran a charge test and I was getting around 8.65w. I was using an extension cord and 20w Apple adapter as I await my Amazon cig light USB-C. Unfortunately I never did a charge test with the Qi charger, but I tried another one in my house and my iPhone 12 Pro was only getting 3.65. I also tried another Magsafe charger in the house and got 8.59w and 12w, so the car isn't producing any worse results.
Thanks for the numbers, pretty big difference between 3.65 and 8.65. I do remember seeing somewhere that MCU2 would put out 7.5w with standard Tesla wireless charger.. Never tested; so I’m not too sure, maybe it’s a placebo but the MagSafe definitely charges faster to me.
I wanted to share these results using the Amperes iOS app. You can see regardless of USB-C, Magsafe or Lightning wired or Tesla modified Magsafe, speeds aren’t great when using either the Tesla USB-A ports or the Auxkey USB-C charger. I question whether doing this Magsafe upgrade over leaving the built in Qi charging is really worth the effort. When using a Magsafe charger with Apple’s 20w Wall charger, I’ll get 8-12w. (Most bottom result is an example of that).
From the manual: The Model S inductive phone charger can charge your Qi-enabled smartphone at up to 7.5W of power. This is using the tesla USB-A.
Yes. Obviously I didn’t test that before I began these tests but the fact wired lightning tested at 3.43 shows how much these results can vary.
I’ve read the MagSafe charger is a bit picky about needing a specific and somewhat oddball USB-C PD 3.0 power profile for max charging speed, and will fall back to a slower one if the power supply doesn’t support it.
