Only in one review: Voltage 30 V (Universal USB-powered voltage converter); Power 15 W (Universal USB-powered voltage converter); In test 14 W (Universal USB-powered voltage converter); Under load 10.747 V (60 V 20 A linear adjustable power supply kit); Price 4.23 $ (Universal USB-powered voltage converter).

Universal USB-powered voltage converter: An interesting, versatile converter, but its readings are inaccurate and current adjustment can malfunction.

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.
