Review conclusion	With reservations	Not recommended

Only in one review: Under load 22 V (XYS3580); Ripple 240 mV (UPS-1228-12); Efficiency 98 % (UPS-1228-12); No load 2 W (XYS3580); Protection 5.2 A (XYS3580).

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

XYS3580: The converter overheats, has high ripple and low efficiency, and its screen periodically turns white.
