Only in one review: Under load 5.16 V (Quick Charge voltage converter); Ripple 300 mV (Quick Charge voltage converter); Efficiency 89.7 % (FR9888); Temperature rise 60 °C (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.

FR9888: Usable up to 2.5 A, but efficiency is below the claim and proper heat dissipation is important.
