Review on 2-Pack Adaptive Fast Charger Type C Cable Kit for Samsung Galaxy S21 /S21 Ultra 5G /S20 / S10 / S10+ / S10e / S8 / S9 / Plus/Edge/Active/Note 8/9 /20/10: Power Adapter with USB C Cord – Efficient and Compatible! by Jerardo Phi

Risk of fire. Bad connections - the plug got hot on first use. A plug that is hot to the touch can cause a fire and electric shock as loose connections generate heat. This should be your first character to disable and not use. If the plug gets hot, the pins will not connect properly to the power supply. This is for any electrical application. Mine came in a pack of two. Only one of these posed a hazard because it was inefficiently manufactured. Both cells worked great, going from 10% to 100% full charge in less than an hour, only one was deemed unsafe as it generated heat in the connector. High temperatures are a major risk factor in electrical engineering. Plugs should never get hot. This item is not UL listed. In the US, our electrical systems are regulated by UL. When something is UL Listed, it means that UL has evaluated the device for fire or electric shock hazards and gives it a UL Mark if it meets safety requirements. My best advice is to test the plug the first time you use it.
