Only in one review: 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.

DC-DC converter with display: The compact converter is usable up to about 2 A, but heats up considerably at higher currents and may fail with excessive input voltage.
