Review on 🔌 Pro Chaser DC-DC Step Down Voltage Reducer Regulator 180W 15A for Scooters, Bicycles, and Golf Carts - 120V to 12V Converter by Oren Perry

There is a lot of confusion in these reviews about how it should be wired and I don't blame them. But maybe my experience will help: the device marks the input and the button as thick/thin red wires, but they have almost the same cross-section and are difficult to distinguish from each other. Connector, with thinner input wires on one side and thicker wires on the other side (see pictures). The input line can also be distinguished from the key line because there must be a fuse at the entrance. The key wire is a bit confusing as it shows the wire that goes to the load. This might be confusing for someone who didn't know that the key/ignition power supply is not normally switchable and is always switched on directly from the power supply. In order to turn on the block for that block, the key wire must be connected to the battery positive and not to the block output. Given the quality control of these blocks, I can't say for certain that all blocks are even made the same way, so I can't guarantee these steps will work for you, but this is exactly what worked for me. Build Quality: The device I received rattled a bit when I received it. I took it apart and found a piece of solder rolling around inside the block. And when I looked at the circuit board inside, I found some amateur soldering work inside (see photos). So I'm skeptical about the quality control between these blocks. The board itself takes up about half of the box in the 72V version, and only a metal heatsink touches one edge of the block. So it's not surprising that they get hot in some people.
