Only in one review: In test 25 W (QC 3.0 charger); Price 2.54 $ (Choetech Q5003).
Choetech Q5003: The charger handles load steadily and runs cool, but lacks cable-drop compensation and its claimed 3 A rating is overstated.
QC 3.0 charger: It regulates voltage well and delivers its rated current, but overheats and has elevated ripple at 5 V.
