I'm fairly sure it should be ok...but can I use my spare Pi 4 PSU to charge a USB-C phone?
We've had little luck getting quality USB-C cables that charge well, and am confident that the Pi4 PSU is quality...
Yes should be OK but might not charge the phone as quickly as the original PSU does if it and the phone are "smart".
Dunno about you, but being smart enough not to set buildings on fire seems like a Good Idea. Problem is the USB-C specification has gotten extremely complicated and implementing it correctly is a major challenge, even if you have the right experience.
What was wrong with using a 9v charger for a 9v device or a 20v charger for a 20v device? Why must the charger be 'smart' and supply multiple voltages at all?
What happens when some complete nincompoop plugs the 20V charger into the device which requires 3V? Devices are supposed to include some level of protection against that, but it is rarely 100%. Does the device start overheating, then catch on fire? Once on fire does it short out the power supply and cause it to catch on fire? Does it take an hour to do this, thus giving the person time to go to another room and start ignoring the item and not realize the situation until it is a full on structure fire?
My usual solution is to make labels for both devices and their associated PSUs so I know what PSU goes with which device. Second line of defense is to put the PSU in the same container (for smallish electronics, this is often a 1 gal. ziplock bag, which has the advantage of being transparent so you can see what's in there).ehem wrote: ↑Wed Oct 23, 2019 11:12 pmKeeping a device paired with an appropriate power supply is good, but the real world has shown that this never works. What of cellphones? If you're isolated at an airport in the middle of nowhere would you rather be able to borrow someone else's charger or have no way to charge your phone which you forgot the power supply for?
