Yeahβ¦ that tracks π β thatβs exactly what happens when a power supply is undersized for a motor.
What likely happened
Your compressor needed:
- ~6A running
- 8β10A surge at startup
Your converter probably was something like:
- 12V 2A / 3A / 5A
π So it got overloaded instantly β overheat β pop / burn β failure
Important question now
Is it:
- Just dead (no output) β
- Or actual smoke / spark / smell π₯
If there was smoke or smell:
π Do NOT use it again (fire risk)
Good news
Your compressor is probably fine π
Motors are tough β power supplies die first.
What you should use instead
For that compressor, get:
- 12V 10A power supply (minimum)
- Better: 12V 15A (safer, cooler operation)
These are commonly called:
- βSMPS 12V 10Aβ
- βLED power supply 12V 10Aβ
Pro tip (very important for motors)
Add:
- A fuse (10A) in series
- Or use a car battery (best for testing)
Car battery = perfect because:
- High current β
- Stable β
- No sudden failure β
Reality check (so you donβt repeat this)
Motors β LEDs or routers
They:
- Pull huge current spikes
- Kill weak power supplies instantly
If you want, I can suggest a cheap setup under βΉ500ββΉ1000 that will run your compressor safely.
