Wireless charging

Cliff14Denali · January 25, 2018

I have a 2014 and retrofitted a usb charging coil which I ran to the usb connection in my console. It charges my Galaxy S8 fine but once you use it for Pandora or Waze, the phone gets an error message for slow charge. I wanted to try using a Samsung Fast Charge coil setup but was wondering if it would actually fast charge. I think I may need to hardwire it using a fast charge usb port. Has anyone tried this?

I haven't, however, I've read that you can't have a fast charging setup with 3 coils. The original GM version of the charger was a single coil, whereas the 2018 version is a 3 coil version, which can provide a good interface for the coils and be more lenient on having a good position to deliver the maximum charge possible. Perhaps they did this to address all the complaints from the single coil version about people not being able to find the "sweet spot" on the charging pad for the phone to stay charging?

I guess what I'm trying to say is that even if you have a fast charging custom setup with the proper power hookup, if the phone isn't exactly aligned for that single coil, you might not see full advantage of the faster charging? I might be wrong about fast chargers only being single coil, but I don't think I've seen a fast charger yet that is 3 coil?

On my other wireless chargers I've used at home, I've found that if you don't have a high enough powered USB power supply, the pad can act finicky. Even if your car adapter says 2.1A, a lot of them aren't right and don't truly put out that power. You might want to test your current with a amperage tester or perhaps try another power source, which could help you with the slow charge issue?

For the guys that went the oem route, I have a 2015 Sierra slt and doing the oem wireless charging route. So now I’m trying to figure where does the connector coming from the lid plug into in the center console? I’ve looked at both a 15 and 17 and both have the same harness pn:23211330.

There is a disconnect on the rear panel of the console. So the main harness will have a branch out at the rear where the new lid will plug into.

I did the same thing. Took apart a cheap wireless fast charger I bought for $13 on amazon. Put it in my center console between two pieces of plastic so when my phone is in the little tray, it charges. I have no issues with running apps and power loss.

Going into the dealership today for them to examine wireless charger not functioning.
Hopefully they will replace with 2018 unit under warranty as it has never worked for me.

Doubt that will happen. They aren't going to deal with the connector difference.

Big shoot out to pgamboa and his video. I was going crazy as to why my iPhone X would not charge in my 2016. I just got my 2018 module and ordered the new conncector. Took about 15 minutes to put everything together and pin the new connector, now everything works like a charm. I did not rotate my mat, and i can charge as long as the phone is touching the back stop.

I do have a 2016 module for sale...if anyone wants a nice paperweight. LOL

Where did you order your 2018 module from?

2017SierraSLT · February 2, 2018

Local GM dealer, or one of the several online GM parts houses.

I know what you mean. I'm just hoping to recoup some of that $100 from ebay with my old charging module. lol
