Only in one review: Current 3 A (USB DC-DC board, type two); Efficiency 95 % (25A 600W voltage converter); Protection 26 A (25A 600W voltage converter); Temperature rise 106 °C (25A 600W voltage converter).

25A 600W voltage converter: An inexpensive converter with good efficiency, but high ripple and overheating shunts at 25 A.

USB DC-DC board, type two: Type two works but overheats, is limited to about 2.8 A, and has worse efficiency and ripple than type one.
