    Great seller, measuring using Drok tester can get 4A staying above 5v from 1s 10A 1C lipo. Could probably go higher but Drok maxes out 4A, thanks for you efforts to help me out

    Great product, fast shipper

    I struggled to find a way to operate led panels in my rv ceiling fixtures. I needed a simple way to power them when wired in series. Since I used 3 per fixture, I needed a way to get close to 36 volts. These little boards are perfect for that purpose. Once hooked up to 12 volt battery, I was able to adjust the voltage under load using the built in volt meter (which read about 2 volts different than my cheap multimeter). Still, I was able to run the lights at full brightness but chose to turn them down to 33 volts since the circuit sees 14 volts when the battery is charging. The brightness is barely less and adequate for my needs. These panels are 4 watts each so are 12 watts in total. They produce more light than the two - 15 watt fluorescent tubes that they replace and can operate on ...

  • Top critical review

    It probably works but not for very low voltages

    As far as I know, this product is alright. But It didn't work for the project I was going to use it for. If you have a project where a small volatage needs to be boosted ( say under 3 volts ) it may not work. The output voltage I was getting was the same as the input even after adjusting the potentiometer. Also, it would be nice if all these electronic gadgets online had links to their datasheets.

  • Works great for my application.

    Using this board to get 19V from 12V battery to power my laptop in my RV.. Works great and is pretty RFI quiet compared to an inverter and the stock power supply for the Laptop. Important when running Ham Radio portable. Only issue I had was one of the screw down terminals on the output was reversed in its housing making it impossible to get a wire into it. Unsoldered the connector and soldered wires to the PCB. Will order another one as a spare.

  • Capable DC converter.

    Great small unit that can run laptops (from lead acid 12V battery) if you have already charged the laptop battery. Will also charge the laptop battery, but you cannot turn on the laptop until battery is full. Put a good mini fan over it. Remember that laptops at 100 percent processing take much more power and may overheat unit. A laptop at idle will easily run off this unit.

  • Wonderful, can't beat it for the price

    excellent product. Very good manufacturing and welds. Good quality components, functional screen so no need to get a multi-meter. (And in my experience, accurate too)
