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 Karen Smith

They work very well because they don't know what to look for and many reviews say that diff chargers are fake and could damage the phone but like that far so good I'll let you know if there are any issues, but I can get 2 Def Beats for $20 per charger direct from Samsung. It arrived very quickly and the packaging looked serious and professional. They work just as well and I even see a popup on my phone when I plug in a charger that says "Fast Charge" which in my experience just indicates if it's charging really fast. Goed from 3% charge to 78% in less than 30 minutes. Incredibly happy. 5 stars so far! Highly recommended.
