Only in one review: Voltage 5.3 V (MP2225 converter); Ripple 80 mV (MP2225 converter); Efficiency 96 % (MP2225 converter); Protection 4.5 A (MP2225 converter).

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

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.
