Only in one review: Voltage 12 V (QC 3.0 charger); Current 3 A (QC 3.0 charger); In test 25 W (QC 3.0 charger); Temperature rise 115 °C (QC 3.0 charger).

QC 3.0 charger: It regulates voltage well and delivers its rated current, but overheats and has elevated ripple at 5 V.

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.
