It does what it should. As there are at least 4 different variants better to tick them immediatelly (it's not ticked in the factory, see my picture) so later on there is no guessing and potential mixing.

I have carried out a test and it seems to work, although I have not applied a load. I tried it with a 3.7V Li-ion battery and got 12.2V output. Very small, perfect for what I need. Received very quickly compared to other shipments.

After measuring the voltage, it was 11.94V. It was very stable. I plan to use this product and 1sLipo for SpeedyBee Bluetooth USB Adapter. thanks

Works nicely, I getting a 11,84v continuously from a 3.7v source.

Recieved product as expected.

Item as advertised

Exactly what I need. Small dimensions and good workmanship.

Delivery is presumably lost along the way, but after reminding the delivery has been forwarded; thanks for that.

Good.

All seems good, will test it this day.
