Only in one review: Under load 10.74 V (DC-DC converter with QC 3.0); Efficiency 94.3 % (DC-DC converter with QC 3.0); No load 1 W (DC-DC converter with QC 3.0); Temperature rise 110.2 °C (DC-DC converter with display).

DC-DC converter with QC 3.0: It works steadily and supports QC 2.0/3.0, but gets hot and has high ripple at 5 V.

DC-DC converter with display: The compact converter is usable up to about 2 A, but heats up considerably at higher currents and may fail with excessive input voltage.
