Review on Quick Charge Adaptive Fast USB Wall Charger for Samsung Galaxy 🔌 S21/S21+/S21Ultra/Galaxy Z Flip 3/S20/S20+/S20Ultra/Note 20/Note10/S10 S9 S8 S7 S6,Note 5,Note 8,Note 9 by John Goerge

I have mixed feelings about these devices. When I first ordered them only 2 out of 4 worked and one of the charging blocks smelled like burnt plastic when plugged in, which I quickly realized there could be a fire hazard. Of those that worked, they offered fast charging. I changed them and when I received the 2nd pack, 1 charge out of 4 didn't work again. They don't seem to be very durable, but they offer fast charging at the lowest price I can find.
