From now on, we can safely say that we are all aware of the dangers of charging a smartphone with a third-party charger, but did you know that smart wearable bracelets (so-called wearables) are also at risk of ignition? Lamar Jackson knows his stuff.
Instead of using the OEM charger that came in the official packaging of his Gear S3 frontier watch to give his device the power it needed, he decided to reach for the Tronsmart Chocolate charger he found in a drawer. It is a wireless charger, but it did not provide sufficient charging power. But at first glance it seemed to work well. Maybe a little too well, although, as Jackson stated, his watch was literally fried.
I had a similar experience when I tried to place the Gear S3 frontier on a wireless charger overnight. When I woke up in the morning, I found that not only was the watch not 100% charged, but on top of that, it was extremely hot. When I then put it back on the official charger (included in the official packaging) it showed a message saying the watch was overheated.
However, this is not a problem only with chargers from other manufacturers, so-called third parties. A Reddit user reported that his Gear S3 reached a high temperature even while charging with a Gear S2 charger.
The Tizen Experts online blog states that the temperature rise may be primarily due to the Gear S3 not fitting properly into its predecessor's dock; which causes current to flow through unintended parts of the watch – the bezel, buttons, display, and even the really small metal connection at the top of the device.
