Review conclusion	With reservations	With reservations

Only in one review: Current 8 A (Used QC 3.0 charger); In test 70 W (CHOETECH Q4004); Efficiency 90 % (CHOETECH Q4004); Temperature rise 100 °C (CHOETECH Q4004); Price 3.4 $ (Used QC 3.0 charger).

CHOETECH Q4004: It stably delivers the rated 60 W and up to 70 W, but runs hot with little thermal headroom at maximum power.

Used QC 3.0 charger: It delivered the rated 8 A on the 5 V channel, but ripple is high and the QC port is faulty.
