Review on ➡️ QEBIDUM LM2596S DC-DC Buck Converter: Step-Down Regulator Power Module with LED Voltmeter Display by Monty Barganier
Cheap Chinese imitation or original, just poor quality
Mine arrived with a loud high frequency hum/hum that only got worse with more current during use and fluctuating voltage, which made them for the rendered useless for the most part. I had to return them for a refund.
- Very good value for money
- Has flaws
