Only in one review: Voltage 12 V (Choetech Q5003); Current 3 A (Choetech Q5003); Temperature rise 81 °C (Choetech Q5003); 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.

5 V 3 A USB charger (power supply): Ripple is high at 2 A and the diodes overheat; the author advises limiting the load to 2 A.
