What modern phone charges at 48V? I'm not aware of any that charge at even 20V, outside of a couple of gimmick devices. No Samsung or Apple phone charges at any

What modern phone charges at 48V? I'm not aware of any that charge at even 20V, outside of a couple of gimmick devices. No Samsung or Apple phone charges at anywhere close to that, that's for sure.
- smileysteve 3y agoWhat modern phone charges at 12v? Most phones charge at 5v. Modern USB-C chargers can charge between 5v and 20v based on configuration. Buck converts and regulators are cheap and small these days.
- nikau 3y agoMost phones charge higher than 5 volts these days
- turtlebits 3y agoSamsung phones can fast charge at 15v/3a (45W).
- Kirby64 3y ago12V isn't a 'standard' USB-PD voltage, so pretty much none of them. Tons of phones charge at 9V, though. And some use 15V. The regulators/buck converters you speak of are inside the phones these days. They want a higher voltage even if the battery itself is 3-4.2V, so losses from cabling are lower and you don't need a special 5A cable to handle charging at the fastest rate.
- bryanlarsen 3y agoI believe Qualcomm's QuickCharge 5 can use the full 48V of USB-PD. Given it allows 100W, I certainly hope so. Regardless, QuickCharge 3 is 20V and it's been in a lot of phones since it was introduced in 2016.
