Review on Converter Step Up In10 60V Electric Modules by Johnny Burns

As shown in the photo, the fan was delivered disassembled. I tested the amp with a very light load (12 volts in, 34 volts at 3 amps out) on the LED. It seems to work; hopefully it will continue as more is asked of him. UpDate, Revain Refunded $5 To Cover Another Fan; Since these are cheap little fans I thought that was fair. If this device performs as well as the one I bought a few years ago, I will be very satisfied in the long run. My first uses an induction heater; input 24 volts and 26 amps; Output 35 volts 18 amps, three years service. It would be 4 maybe 4.5 stars but in my opinion there is no need to fix a brand new item. 4/2/20, back to two stars. Oh, that thing must have gone through hell in the shipping process. Today I had to solder a small jumper on the output side. I have intermittent fluctuations in amps and also in voltage. It seems it was a cold soldering that affected the additional damage during transit. I cannot, in good faith, recommend this seller; Product yes, seller no. Although Revain was willing to work to fix these issues, the seller didn't even take the time to respond.
