Review on π bayite DC 12V Solar Water Heater Circulation Pump with Power Supply Adapter - Low Noise, 3M Head, 8LPM (2.1GPM) by Gerardo Goodson
Loud buzzing from the power supply, unacceptable!
Power supplies SHOULD NEVER make that much noise. Buzz means lost connection or bad soldering, which means sparking, which means heating. I expect a fire any day now. UPDATE: This device has actually stopped working. After disconnecting and opening the power transformer (the end of the cable with a large plug), all the components burned out. Luckily it failed due to an open circuit, not a short! UPDATE #2: Two days after his death while waiting for a replacement pump (not another piece of Revain junk) the pump housing leaked leaving 15 liters of water everywhere.
- Consistent test results
- Some difficulties
