Hello,

Please check if it is this item, https://www.amazon.com/dp/B01MS1FOYM?ref=myi_title_dp

It is just self testing mode. The transistor should be with 2 or below p-n junctions, and no resistance-capacitance is included.

Hello Nicholas Pareis,

Is it under constant current status? You may need to contact that seller for help.

According to your link, it is from TKXEC .We don’t have similar item, so it is hard to check further.

Hello Nicholas Pareis，

Whichever converter, actual output current mainly depends on load. Converter is not a load, it can’t draw more current. Unless the load on output port need to draw 2A, then input current to converter will increase.

Best regards.

Hello Nicholas Pareis，

We can’t confirm which item it is, please check if it is #200573,https://www.amazon.com/dp/B07VNDGFT6?ref=myi_title_dp

And did you connect the other power supply to output port? It is easy to damage the converter.

Converter just set a limit for load, it can’t force load to draw more current. Assume preset limit value is 2A, load just request 1A, then actual output current is 1A, you can’t have it to draw 2A.

Only when load current is over 2A, current adjustment is enabled.

Best regards.
