Only in one review: Current 18 A (QBW018A0B); Test current 25 A (25A 600W voltage converter); Efficiency 95 % (25A 600W voltage converter); Protection 26 A (25A 600W voltage converter); Price 5.47 $ (QBW018A0B).

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

QBW018A0B: It runs hot at full load and needs cooling; the author advises against drawing more than 8 A for long without forced cooling.
