Review on π‘ SDTC Tech 5pcs Upgraded DC-DC Boost Converter 2V-24V to 5V-28V 2A Adjustable Voltage Regulator Micro USB 5V 9V 12V 24V Step Up Power Supply Module by Justin Santiago
Not very flexible, but works if you choose an input voltage
The adjustment screw must be adjusted ^before^ the input voltage is applied or it may self-destruct. Different input voltages produce different output voltages with the same trim setting. DO NOT expect to connect a USB cable OR a 12V battery as input and get the same output voltage you configured it for. I set mine to 10V output with 5V input, then connected it to 15V input and it instantly burst and died. I think I'll just use them with USB as input. Works fine except for this one. I got 450mA from one with 5Vin/10Vout and it was comfortably warm to the touch.
- Several competitors
- Not bad
