Only in one review: Current 2 A (5 V UPS); Ripple 100 mV (5 V UPS).

5 V UPS: It is cheap and handles the rated current, but the author was disappointed by the large voltage drop when switching to battery.

Small Step-Up boards (5 V): Cheap, functional boards with good protection; weak as SEPIC converters, but the modification worked.
