- Confirm the input range is universal (100-240V AC).
Key Takeaway: Exact voltage matching is the most critical step in hardware safety.
| Step | Metric | Goal | |
|---|---|---|---|
| 1. Voltage | Exact Match | Prevent Circuit Burnout | |
| 2. Amperage | Match or Exceed | Prevent Power Starvation | |
| 3. Polarity | Correct Orientation | Avoid Polar Reversal Damage |
Never compromise on voltage matching, as even a 1-volt difference can cause terminal damage.
