Can a Portable Power Station Run a Mini-Fridge?
Yes, but size matters. Your power station needs enough surge capacity to handle the compressor startup (120-400W), and enough battery to last through duty cycles.
How Much Power Does a Mini-Fridge Use?
| Metric | Range |
|---|---|
| Running watts | 40–100W |
| Startup surge | 120–400W |
| DC power possible? | Yes |
Running watts when compressor active: 40-100W. Average with duty cycle: 25-60W. Startup surge 2-4x running watts. 12V DC mini-fridges have near-zero surge.

FAQ
How long can a power station run a mini-fridge?
A 1000Wh station can run a typical mini-fridge for about 24-36 hours thanks to the compressor duty cycle (the fridge only draws power ~33% of the time).
Will my power station handle the fridge startup surge?
Mini-fridges surge to 120-400W on startup. Any station with 500W+ surge capacity can handle it. Check your station's surge (peak) rating, not just continuous watts.
