SUMMARY
The discussion centers on the use of a universal power supply adapter with a treadmill display monitor that requires a 6V input and has a current rating of 1.66-2.0A. A user inquired about potential damage from using a 3A adapter. It was concluded that no damage should occur, as the adapter operates as a constant voltage source, allowing the device to draw only the current it requires. This principle is based on Ohm's Law (V=IR), which governs the relationship between voltage, current, and resistance.
