If you're not using the USB-C, you're missing out

There's nothing here to see. I just plugged my s10e in with USb c.... 29% charged, 1hr 29min till full charge. Plugged into regular USB port next to it. 29% charged, 1hr 29min till full charge. Same.

Does a 2015 Silverado have a usb-c port in it

[Chet]

Has anyone actually found the specification for the max wattage on the USB c port?

 

I can't find it. But I know it won't even do 65watts on the new-style 2019 Sierra. It's actually pretty pathetic. Good thing this truck still has 12v outlets and 12v USB c adapters are small and inexpensive.

I don't know the spec for the outlets in truck.

 

My S22 Samsung has 3 wired charging modes that it calls regular, fast and superfast.  I have then all enabled.

It will indicate the charge mode when a cable is connected. 

Phone was released early 2022.

Improved charge speed was one of the features of this model.

 

 

As indicated by others, the charge rate depends on charge source and on cable used.

The block that came with it has both A and C outlets. 

A is labelled 15W

C is labelled 35W

 

Using the A outlet it charges uses 'fast' charge.

Using the C outlet is uses superfast 'superfast' charge. 

 

Using the A cable and an old block from a Blackberry it uses 'regular' charging 

Using the A cable and an LG block labelled 'fast charging' and the phone indicates it is in 'fast charge' mode.

In truck, using the A cable it uses 'regular' charging.

 

In the truck I always use a C cable.

The phone always charges using 'superfast' charge mode. 

 

 

Superfast wasn't available my previous phone.  

But Samsung increases the possible charging rates for this 2022 phone release. 

 

I used this phone (released in 2022 in my 2021 truck. and don't recall what mode(s) it charge in. 

 

GM is known for improving features with new model years.

Perhaps not so good at guessing what charge rates / features the phone industry will adopt in the future?
