Review on π BOYISEN 5V 3A Output Converter: Waterproof DC-DC Step Down Voltage Regulator for Automotive Car, Smartphone (Micro) by Michael Tran
Is working. As it should.
This item works. It does what it was designed to do. I used it to power a new keyboard that required USB power from an old wired alarm keyboard.
- Starters, Chargers & Portable Power Supplies
- Definitely bad product
