Nice, cheap and good DC-DC converter for Li battery. 5V output to USB-connector. With undervoltage protection when battery voltage drops below 2.5V and overcurrent protection.
funziona bene

Great product!
perfect
It does what they claim it does.
Good quality pcb. Great for providing 5V to power USB devices from a 16850 li-ion battery.
Works well, no problems. Good unit for the price
these are very good. I solder a 12v dc barrel socket directly to the board end, and use them to power fones and pi from car battery and screen.
