Only in one review: Ripple 80 mV (MP2225 converter); Protection 4.5 A (MP2225 converter); Temperature rise 108 °C (MP2225 converter); Price 1.67 $ (FR9888).

MP2225 converter: The compact board meets its stated specs, but sustains 4 A only briefly and heats up noticeably under prolonged load.

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