I'm 100% positive that this charger had caused my phone battery to swell for my Samsung Galaxy Note s20 + Ultra. My phone never had a problem in the 4 years that I owned it until I had this charger on it. The phone battery swelled, causing the backing to completely pop off even the camera during a charging session. The phone in the image is what happened to, take a close look and notice how badly it ripped apart.
I took it to AT&T — my phone provider — and they had confirmed that it was the charging station that it was on. They informed me not to use a charging station like this, as it's more likely to cause these problems if it's a third party device and not the actual Samsung product. Lesson learned. I had just paid off my phone too several months ago, so for this to happen now I'm really disappointed.
I'd give this 0 starts if I could, and I'd note that this does NOT stop charging the device once it has reached 100%. The phone is still charging, allowing the phone an opportunity to overheat while you're sleeping. Make sure to have your adaptive battery settings turned on if you haven't done so; I've done this now with my new phone, and won't go looking back to a full 100% charge.
