S20 wired charging

[rbd]

Hi all,

I just bought an S20 FE 5G which came with the slow 15w charger, and I have already bought the Samsung 25w charger, so all good there. However, I've still got a boatload of leftover Aukey Qualcomm Quick Charge chargers (both 2.0 and 3.0) bought for other phones in our family, including a cigarette lighter unit for the car. Can I still use these with my S20 FE?

I understand that the S20 is designed for USB PD 3.0 charging (as opposed to Qualcomm QC), but the QC product support lists I've been able to find show that many Galaxy S* phones had support for QC 2.0 (but apparently not 3.0). I don't really care if the S20 will charge quickly or slowly using a Qualcomm charger, I just want to know if I can safely charge it without risking damage. I REALLY don't want to have to drag multiple cigarette lighter chargers around in our car!

Samsung's support chatbot of course says you should never charge the phone with anything other than a Samsung-made charger. A predictable response I suppose, but not very illuminating.

Thanks!

I use my old chargers on my S20 without issue. It seems to have four charging modes (wired) depending on the charger and cable. Slow, Charging, Rapid Charging, and Turbo Charging. I think there are only two modes for wireless charging, regular charging and turbo charging.

Thanks, Unforgiven. Are your old chargers Qualcomm Quick Charge?

Some are, I use a QC03 on my truck connected to a YEOTECH (sp?) wireless charger / phone mount and I get fast charging through that. I have found I need to mix and match charger blocks and cables as some don't work well together. Most of my cables are OEM or Anker.

Sorry to be a pest, but just to clarify -- have you used any QC chargers via a direct wired connection to the USB-C port on your S20, or only indirectly through wireless charging? I can imagine those two scenarios could be quite different.

Thanks!

I'll be honest I'll have to check. Like I said, was was mixing and matching charging blocks, cables, and when applicable, wireless chargers.
