USB-C for dummies
« on: January 10, 2022, 02:56:12 PM »
I just now exchanged my S7 for an S20, and I need a primer* on USB-C. My main question is about the faster charging w/ USB-C. Is it all in the cable, or is the charger itself different?

I'll take my answer off the air. Thanks.


*Didja know it's pronounced "primmer," rather than "primer," like the paint? Didja? Or maybe somebody just told me that as a joke, and I've been sounding like an idiot every time I say it.

USB-C supports a lot of power.  Laptop USB-C chargers can go to like 100W.  Cellphones can usually only accept 15-20W.  So you will need a phone capable of fast charging (you have) a USB-C cable (you have) and a transformer capable of putting out enough power. 20ishW@5VDC so  [carry the two] 4 amps or so.  (Do you have?) 

The S20 should support wireless charging as well, so there's that option.

ETA:

Samsung says the S20 ships with a 25W charger, so you should be able to just plug that in with the USB-C to USB-C cable that came in the box.

ETA Again:  I did know it was pronounced "primmer".  Picked that up somewhere in school, maybe from a Neil Stephenson book.

Yes, and yes. Dogmush filled in the rest.

Most everything is transitioning to USB-C for the power handling capability, plus the connector being unidirectional and more physically robust. You'll really appreciate it if you do large file transfers to/from your phone.

Also, you can get a USB-C to HDMI dongle that will let you use your phone on any HDMI-compatible monitor. Comes in handy if you need something larger than your phone to display things.

I have been aware of it for a long time. I used to actually pronounce it properly. Then I got tired of all the aforementioned looks . . . .

I always assumed that like many words, "primmer" is English English (and /or old American English) and "primer" is American English. I think I've only heard it pronounced the former way by brits.

We always pronounced it "primmer" in my family. But I'm an oldster -- I grew up before "ain't" was in the dictionary.

That ain't hard for me to believe.  =D
