Only in one review: Voltage 5.2 V (DC-DC converter with QC 3.0); Test current 5.1 A (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 100 °C (TPS40057-based converter); Price 1.43 $ (TPS40057-based converter).

TPS40057-based converter: The board handles up to 9.5 A, but the input diode gets hot; the author recommends bypassing or relocating it.

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.
