Hi. Shipment came fast. 6 days to Croatia. Each product in separate bag. Tried and it can not give 0.8A from 3.7 to 12v on 4100mah lipo batt. So no good so far. Will try on 18650 but...

It is a mighty little module, a great addition and building "brick" for your DIY projects. It starts to give output from about 2.8V and cuts out at 2.7V. Be careful though, when you set your output to a value with the input being 2.8V, the change in the input will result in a great change to the output, but this is not specified/guaranteed mode anyways... It may be necessary to keep the output under certain load to achieve stabilization, I will give it some test later on...

Perfect Buck-Boost Converter. Useful for projects where you may need a different output voltage of this DC - DC converter. I highly recommend it.

Los circuitos llegaron completos y en buen estado. Comúnmente compro en Banddoog y dejo el envío por default. Pero esta ves, pague por el envío y me llego en 5 días (De China a México). Fue rápido y barato. Lo recomiendo

Excellent little module, Very useful for running 12 and 24 volt relays from 5v. Good value, very versatile. In my opinion, a very good buy.
