Many of clients ask us the same question about QC chargers – what is the big difference between QC 3.0 and QC 2.0 ? It seems easy to answer –

  1. QC 3.0 is 30% faster than QC 2.0. It would protect the phone battery and make it recycle more times as well.
  2. Intelligent Negotiation Opti voltage will help QC 3.0 to max the power of charging.
  3. QC 2.0 can charge a phone to its 50%. But QC 3.0 could charge a phone from 0% to 80% in 35 minutes. QC3.0 can reduce the loss of power up to 45%.
  4. QC 3.0 is designed to charge the phone max at a high speed. The voltage was designed from 3.6V to 20V. And the currency would go up or down at 200mV as a stage standard. This would help QC 3.0 to charge the phone at max speed and cause less heat and reduce power when charging.
