Review conclusion	With reservations	Recommended

Only in one review: Voltage 12 V (QBW018A0B); Test current 17 A (60 V 20 A linear adjustable power supply kit); Under load 10.747 V (60 V 20 A linear adjustable power supply kit); Ripple 100 mV (QBW018A0B); Temperature rise 111 °C (QBW018A0B); Weight 360 g (60 V 20 A linear adjustable power supply kit); Price 5.47 $ (QBW018A0B).

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

60 V 20 A linear adjustable power supply kit: An interesting, easy-to-assemble kit with good stability, but its relay and fuse must be replaced to reach the rated 20 A.
