🔌 DC-DC Buck Voltage Converter: DROK Adjustable Step Down Voltage Regulator with LCD, USB Port, and Protective Shell Review

Item arrived in order. All functions worked as expected, except for the 5V USB charging port. I tried plugging the charging cable into the port and it broke. I asked to return it, they said don't worry we will send you another one but it will take 2 months to receive it. Thank you for the great service. More than a month went by and I received an email saying my replacement was cancelled. HOORAY! I bought a crappy charger and even took the time to assemble it myself. DROK wasted a month of my…

Nice looking unit, had high expectations. But the item I received had a few quality issues, the circuit board wasn't completely cut, I ended up cutting off part of the circuit board on the output side, no big deal, but for the price better quality was to be expected. Compared to what is offered on Banggood. The input connectors were very weak even when touched, and the accuracy wasn't the best even after calibration. I think I got the lemon and won't hold it against Ginster as there are so many

Just want to make sure I'm doing it right as I've never used any of these before, choose the mode you want ie. OUTPUT VOLTAGE, then use the buttons to set the desired voltage and current, THEN connect the multimeter to the output (USB or bare wire) and use the screws to set the voltage so the multimeter reads the same like the screen. (SOURCE --> DEVICE --> MULTIMETER). Therefore, to perform the same calibration with INPUT current, you need a multimeter in front of (between the device and

It arrived with the case and screws disassembled but was easy to assemble. This is a very good power regulator, although I wish it had written on the page that this product can only support or step down the voltage as I didn't know about it. I love how it can display the input/output voltage and current in real time! There was a small extra piece hanging from the circuit board, but it was very easy to carefully remove (I just used pliers to remove it). The guide is decent and surprisingly…
