Appendix 1: Explanation of terms
Quick charge: fast charging, modern fast charging mostly refers to the charging process
when the charging current is greater than 2A or the charging power is greater than 10W.
Quick Charge Protocol Detection: Detect which quick charge protocols are supported by
the charger.
Quick Charge Protocol/Quick Charge Mode Recognition: Identify what fast quick is
currently in progress.
Decoy/trigger: Simulates a quick charge protocol sequence that allows the charger to
output high voltage/high current.
Quick Charge Simulation: Analog protocols which chargers do not support to improve
charger compatibility.
Common part of the quick charge agreement:
Qualcomm: QC2.0, QC3.0, QC4+
Media Tek: PE2.0, PE3.0
Huawei: FCP SCP
OPPO: VOOC, Super VOOC
One plus: DASH, Warp
USB Type-C: PD2.0, PD3.0, PPS
mAh, mWh: milliampere hour, milliwatt hour, milliampere is the capacity unit. Milliwatt hours is
the unit of energy.
Appendix 2: Basic Operational Knowledge
I: measure the capacity of power bank
Preparation materials: power bank to be tested, USB tester, HD35 electric load or mobile
phone, charging head.
the data need to view： the capacity energy value of the power bank (mAh mWh), the
voltage and current value of the power bank output
First charge the power bank, then adjust the current meter to the non-zero data group,
then use the power bank to charge the mobile phone or use the HD35 electronic load to
discharge to the power bank to automatically shut down, use the charging head to supply
power to the tester, and then Record the mAh, mWh values on the tester.
Method 1: The comparison tester shows that the mWh is divided by efficiency (like 90%)
and the power bank mWh. If the difference is not large, the capacity of power bank is real (the
most accurate method).
Method 2: If the mobile phone is 5V charging, the tester displays mAh multiplied by 1.5. If
the mobile phone is a 9v charging tester, the mAh multiplied by 2.7. If the value is not much
different from the technical parameter of power bank. The power bank’s capacity is real. (only
applicable to power bank without mWh).
Since many mobile power sources are currently tens of thousands of mAh, if you simply
charge the mobile phone to measure the capacity of the power bank. You need to charge the
mobile phone many times. It takes even a week to measure the capacity of power bank, in
