Wall charger USB port

#1

Hello, I have 2 questions:
1- Can anyone tell me about the USB ports of these chargers? USB 3.0 or USB 2.0?
2- Which of these chargers have 3 feature “power IQ”, “MultiProtect” and “Voltage Boost”?

Anker support would probably be able to better answer this question. Email them at support@anker.com.
