I recently realized USB-C charging is a lot mroe advanced than regular USB charging

While I've had USB C devices for 10 years now, I just recently got my first USB-C 130 watt charger and USB-C 65 watt power bank and they made me realize USB-C has a lot of extra options for charging including up to 100 watts power.

While regular USB charging just provides 5 volts all the time like a 5 VDC AC adapter, USB-C seems to involve a conversion along the lines of:

Device 1: Hey what's up? I'm a USB charger, what are you?
Device 2: Hey, I'm a phone, my battery could use a charge!
Device 1: I can provide 100 watts of power at 20 volts, 5 amps
Device 2: I can only accept 15 watts of power at 5 volts, 3 amps!
Device 1: OK, I'm sending you 5 volts, 3 amps

My USB-C Power bank has a display that shows the battery level with 1% accuracy, and the input/output volts and amps depending on whether it's being charged or charging something else, that's how I noticed there was some sort of conversation between the devices before it decides how many volts and amps to provide.

Charges chit way faster.

Get a GaN charger. I have a charging station which does 90w usbc. My Xiaomi phone is charged in like 10minutes.

The charger I got is GaN.

Be careful with fast charging, it will destroy your batteries in no time. I intend to use it only either for large batteries like my battery bank in which case it's not that fast of a charger or for rare occasions where I may need to charge something fast. Using fast charging all the time will destroy your batteries in a year or so which you want to avoid especially on devices with non replaceable batteries.

My smartphone is 10 years old and still lasts 1-2 hours of actual use on a charge because I always used a 5 volt, 2 amp charger. If I had been using a fast charger it would probably last 15 minutes per charge after a year or two.

If you have a 2014 phone, 2A charging was fast charging. 0.5/1A were standard back then.

Charging to 100% for extended periods of time is what kills batteries. Keep a battery between 30% and 80% charge and you'll see virtually no long term degradation of capacity. My batteries are fine after 5 years of 18w fast charging.

if you ever try to convert usb things to usb c you need to mess around with resistors and the CC pin

CC1 and CC2 need to go to ground with a 5.1k resistor

to clarify,i f converting from usb A to usb c
if male CC1 or CC2
if female CC1 and CC2

Like they aren’t suppressing near perfect technology that you have paid taxes & worked in menial jobs to provide support & sustainability to scientists inventing this technology

Yet they drip feed you chit tier products
