Short answer: don’t just connect and “see what happens.” You might damage the converter.
Let’s break it down simply 👇
Your compressor
- 12V, 70W
- Current needed = Power ÷ Voltage = 70 ÷ 12 ≈ 5.8A
👉 So your compressor needs ~6 amps (and maybe 8–10A peak when starting).
Your AC → DC converter
You said:
- It’s 12V
- But you don’t know the watt or amp rating
⚠️ This is the risky part.
