A portable camping fridge uses 45 watts running, 80 watts surge to start the compressor, with 35% duty cycle.
Quick Answer Box:
- Running Watts: 45W
- Starting / Surge Watts: 80W
- Running Amps: 0.38A @ 120V
- Duty Cycle: 35% – runs 21 minutes per hour in 75F ambient
- Daily kWh if left on 24/7: 0.378 kWh
This is a compressor fridge, not a thermoelectric cooler which uses 60W at 100% duty.
How Much Does It Cost to Run a Portable Camping Fridge?
Formula: Watts x duty x hours / 1000 x $/kWh = cost
At $0.15/kWh, 24/7 in a van at 75F:
| Usage | kWh per Day | Cost per Day @ $0.15 | Cost per Month @ $0.15 | Cost per Month @ $0.30 |
|---|---|---|---|---|
| 8 hrs/day | 0.126 kWh | $0.018 | $0.56 | $1.13 |
| 24 hrs/day @ 35% duty | 0.378 kWh | $0.056 | $1.70 | $3.40 |
| 24 hrs/day @ 60% duty in 95F heat | 0.648 kWh | $0.097 | $2.91 | $5.83 |
At California $0.45/kWh, 24/7 at 35% duty costs $5.10 per month.
Can a Portable Power Station Run a Portable Camping Fridge?
Yes. A portable camping fridge needs 45W continuous and 80W surge. All 22 stations pass.

What Size Generator Do You Need for a Portable Camping Fridge?
Minimum 80W continuous with 80W surge. MARBERO Portable Power Station 88Wh at 80W, 120W surge passes for 1.7 hours continuous, 4.7 hours real.
Recommendation: 500W – 1000W. For 24 hours you need 445Wh usable at 35% duty. That is 45W x 24h x 35% / 0.85 = 445Wh. BLUETTI AC50B at 448Wh gives 24.2 hours real, which is the minimum for a full day. For 3 days, use Anker C1000 Gen 2 at 1056Wh for 57 hours real.
2 Tips to Save Power on a Portable Camping Fridge Only
1. Pre-chill at home on AC power and add frozen water bottles. A portable camping fridge uses 80W surge for 2 minutes to cool from 75F to 37F, then 45W at 35% duty to hold. If you start warm in the van, it runs 100% duty for 3 hours – using 135Wh just to cool down. Pre-chilling at home on wall power saves that 135Wh. On a Jackery Explorer 300, that extends real time from 15.8 hours to 20.5 hours. Adding 4 frozen 500ml bottles adds thermal mass and drops duty from 35% to 25%.
2. Keep it out of sun and leave 4 inches behind. Camping fridges vent hot air from the back coil. In a van in sun, ambient behind the fridge hits 110F and duty jumps from 35% to 60% – cost doubles from $1.70 to $2.91 per month and runtime on BLUETTI AC70 drops from 41.4 hours to 24.1 hours. Place it in shade and leave 4 inches gap behind. This tip is only for compressor camping fridges, not for mini fridges which vent differently.
FAQ
How long will a portable camping fridge run on Jackery Explorer 300?
5.5 hours continuous at 45W, 15.8 hours real at 35% duty. Real world in 75F about 14 hours because door opening adds 10% duty. At 95F ambient, 9 hours real.
