Only in one review: Voltage 5.3 V (MP2225 converter); Test current 4.5 A (MP2225 converter); Under load 5.02 V (TPS40057-based converter); Efficiency 96 % (MP2225 converter); Protection 4.5 A (MP2225 converter); Price 1.43 $ (TPS40057-based converter).

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

TPS40057-based converter: The board handles up to 9.5 A, but the input diode gets hot; the author recommends bypassing or relocating it.
