Bought to try to power a Raspberry Pi Zero W from 2x AAA (I know, bad idea, but the pi is a retrofit into a case that already has a 2x AAA battery compartment). This module caused the pi to go into a boot loop, because when the current draw from the pi spiked, the battery voltage dropped below the shutdown voltage of 2V (presumably due to their internal resistance) and the output voltage then dropped to match the battery voltage instead of being boosted to 5V. Also, one was damaged in shipping and had a piece broken off of one of the inductors.
