Review on Boost Converter Module for DC-DC Step Up Power with 5V Output Voltage: 1.5V, 1.8V, 2.5V, 3V, 3.3V, 3.7V, 4.2V to 5V Regulator Voltage Boost Converter Board for 0.9-5V to 5V (Pack of 10) by David Bowens
Really tiny form factor - with tiny output power
It's incredibly small (e.g. Apple AirPod). I used it with a D (1.5V) battery to power the Ardruino Nano. This works pretty well. But when I added a speaker, the DC/DC converter couldn't keep up. I measured the peak current it can deliver as 7mA. That's a little less than the >400mA in the product description! Running the same circuit with a desktop power supply shows a maximum current draw of 14 mA. I tried 4 out of 10 devices, they all had the same limitations. 7mA is quite reasonable for such a small device, but make sure it fits your needs before ordering!
