Only in one review: Under load 3 V (MT3608); 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.

MT3608: The original board has poor layout and high ripple, but works better after modification.
