Review on Dual USB Fast Car Phone Charger Adapter Plug with 6FT Micro USB Cord Cable for Samsung Galaxy S7 S6 S4 Edge, A10s A10 J3 J7 Crown J7 Sky J7 Star Prime, LG K50 K40 V10 K10 - Android Home USB Wall Charger Port by Jay Lopez

The car charger fell apart quite a bit after I used it once. I had it charged and when I tried to unplug it from my car, the black frame around the USB port came loose and everything else came out of the car charger itself. It wasn't good. it was very very cheap. However, USB cables have been studied and charge easily with a regular wall charger. My Samsung Galaxy 7 edge doesn't say "Fast Charge" but the time it took to fully charge my phone was fast enough.
