Only in one review: Voltage 28 V (UPS-1228-12); Current 8.3 A (UPS-1228-12); Power 100 W (UPS-1228-12); In test 100 W (UPS-1228-12); Under load 12 V (LTC3780-based converter); Efficiency 98 % (UPS-1228-12); Temperature rise 106 °C (UPS-1228-12); Price 40 $ (UPS-1228-12).

UPS-1228-12: The board showed high efficiency and exceeded its rated power, but it is expensive and has an awkward auto-start behavior.

LTC3780-based converter: An interesting, powerful buck-boost converter, but it falls short of its ratings and needs improved cooling.
