Q&A

Q:My charger nominal maximum support QC2.0 12V2A How do I test if the charger is supported?

A:Insert the load, short pre the trigger on TRG, enter the fast charge protocol selection interface, through the rotary en point selection QC2.0 mode, short pre the en potentiometer, the liquid crystal will dynamically display "----", activate QC2.0 fast charge mode, LCD downlink display '-5.0 ', by rotating the en potentiometer, select '- 12.0 ' file, LCD uplink will show the actual voltage, see if the actual voltage is around 12.0V, and then short pre the En potentiometer on, back to the load interface; Open the load, slowly adjust the current to 2 A, see if the voltage has a significant drop (>0.5V), then let the load work for a period of time, and measure the heat of the charging head. If the load restarts or the voltage drops significantly and the charging head heats up sharply, it means that the charging head load capacity is not sufficient and must be used in a reduced amount.

Q:Is my PD2.0 charger supported?

A:The load can age the PD charger, but PD seduction is not poible. The two-headed type-c line connects the PD charger and the load, and the PD charger outputs 5V by default. If the PD charger supports QC2.0 at the same time, high preure aging can be achieved by luring QC2.0.

Q:I want to release fast charge how to achieve?

A:Method 1: In the load interface, long pre the trigger on TRG to detect the charger on the fast charge mode support situation, after the test is completed short pre the En potentiometer on, back to the load interface, then the original selected fast charge mode will be released; Method 2: Long Pre the En potentiometer on into the Setup interface, select the ' AUTO:OFF ' state, and then put the load back on the power, the original selected fast charge mode will also be released.
