DC 3.3V 3.7V 4.5V 5V to 12V Boost Voltage Regulator Module Converter Step Up Power Supply Board
A part of the review has been auto-translated.
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.
IT WORKS ! When appllied 3.7v I got 12v. Although, when I applied 7.2v, I got 7.2v. I have yet to try other voltage. It seems as if therre is a threshhold to the imput. Great for 12v leds where wheight is a consideration. I use mine with a 12v led spot light with a 250Ma lipo on a drone. Nice and bright and low weight. Be aware that the same laws of elecricity apply. Up the volts and lessen the amps.Not good for a motor. My 6v brushed runs at half the speed at 12v becuase it's half the amps. Simple I/ER.
very quality good product i will buy more i will recommend it to all it it ass described and as shown in the pictures.. only 1 thing i would like to say is that the power is 12v but output amp is very low perfect buy for the price..
Used it to power a 12v led with a 3.7volts battery. Works well. Warning though : the pins are very close to each other due to the size of the module, so you'll need to solder precisely (or use a connector)
