Only in one review: Voltage 5 V (Quick Charge voltage converter); Under load 5.16 V (Quick Charge voltage converter); Ripple 300 mV (Quick Charge voltage converter); Price 1.34 $ (Quick Charge voltage converter).

Quick Charge voltage converter: A compact, inexpensive QC converter, but ripple is high and it cannot sustain maximum 5 V load for long.

LM2596 DC-DC converter board: The board works, but its ICs may be counterfeit; the author recommends keeping the load at or below 1.5 A.

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.
