Review conclusionWith reservationsNot recommended

Only in one review: Voltage 60 V (CHOETECH Q4004); Ripple 200 mV (CHOETECH Q4004); Efficiency 90 % (CHOETECH Q4004).

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

AUKEY PA-T15: The PA-T15 had failures, QC3.0 did not work on the replacement, and AiPower outputs sagged under load.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
