Total scam.
If I could give them a zero, I would. I ordered four fast chargers with four ports for me and my son. When I got it in, finally, I plugged my phone in and it literally said slow charging.. I tried different phones on the different ports on that one charger and it was all the same. I requested a refund and they said they would only give me 20 bucks or I had to send everything back to China at my own cost for full refund. Total scam
