Can a Portable Power Station Run a Mini-Fridge?
A typical mini-fridge runs about 10 hours on a 300Wh power station, 16-17 hours on a 500Wh, around 34 hours on a 1024Wh unit, and roughly 68 hours on a 2048Wh. The compressor only draws power about a third of the time, so runtime is much longer than a constant-load estimate. Any station with 500W+ surge capacity can handle the startup, so even small units work for short outages.
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 the compressor is active: 40-100W. Average draw with the typical ~33% duty cycle: about 13-33W. Startup surge 2-4x running watts. 12V DC mini-fridges have near-zero surge and run noticeably longer on the same battery.
How Long Will a Portable Power Station Run a Fridge?
Based on 70W compressor draw with a 33% duty cycle (23.1W average) on AC, 10% reserve, 85% efficiency. Real fridges cycle on and off, so actual runtime can vary with ambient temperature, door openings, and how full the fridge is.

FAQ
How long will a portable power station run a mini-fridge?
A typical mini-fridge gets about 10 hours on a 300Wh station, 16-17 hours on a 500Wh, around 34 hours on a 1024Wh, and ~68 hours on a 2048Wh. The compressor cycles on and off ~33% of the time, which stretches runtime well beyond a continuous-load estimate.
How long will a 500Wh power station run a mini-fridge?
About 16-17 hours for a typical mini-fridge. Plenty for an overnight outage, and enough margin for a long sleep-in.
Can a small power station run a mini-fridge overnight?
Yes. Even a 300Wh station with a 500W+ surge rating handles a typical mini-fridge for ~10 hours. For 24-hour coverage, step up to a 500Wh or larger.
Will my power station handle the mini-fridge startup surge?
Mini-fridges surge to 120-400W on startup. Any station rated for 500W+ surge can handle it. Check the station's peak/surge rating, not just continuous watts.
Will a Jackery 500 run a mini-fridge?
Yes. The Jackery Explorer 500 (518Wh, 1000W surge) easily runs a typical mini-fridge for ~17 hours. The 1000W surge rating handles even high-draw mini-fridges on startup.
Can I use DC power to run a mini-fridge longer?
If you have a 12V DC mini-fridge (the kind built for cars/RVs), yes — DC bypasses the inverter and extends runtime by ~10-15%. Standard household mini-fridges are AC-only and don't benefit from this.
