|---|---|---|---|---|---|
| Crock-Pot 6-Quart Cook and Carry (SCCPVL610SA) | 240W | 240W | Safe | ~17.9h | OEM Verified |
Show expert analysisTechnical: **Running load:** 240 W. **Surge:** 240 W (no inrush spike). **Voltage:** 120 V AC required. Resistive heating element draws steady current with no motor or compressor startup transient. Field note: Verify power station AC inverter capacity exceeds 240 W continuous rating. Reserve at least 20% headroom (300 W minimum inverter rating) for thermal stability during extended runtime. Can I run this slow cooker on a portable power station all day? Only if your power source can supply at least 240W continuous and 240W surge at 120V. | |||||
| Crock-Pot 7-Quart Manual Slow Cooker (SAP_2131381) | 300W | 300W | Safe | ~14.3h | OEM Verified |
Show expert analysisTechnical: **Running load:** 300 W. **Surge:** 300 W (resistive heating element, no motor startup). **Voltage:** 120 V AC required. Power station must sustain 300 W continuous output at 120 V for safe operation. Field note: Verify power station rated capacity exceeds 1800 Wh if running the full daily cycle. Add 10-15% margin for inverter efficiency losses. Can I cook an 8-hour recipe on a single charge? Only if your power source can supply at least 300W continuous and 300W surge at 120V. It depends on the power station's usable capacity. An 8-hour cook cycle requires 2400 Wh minimum, plus inverter overhead. Verify your unit's rated watt-hours before planning extended recipes. | |||||

Show expert analysisTechnical: **Running load:** 210 W. **Surge:** 210 W (resistive heating element, no inrush). **Voltage:** 120 V AC required. Power station must deliver clean 120 V output and at least 210 W continuous capacity. Field note: Verify power station capacity exceeds 1260 Wh if running a full daily cook cycle on battery alone. Leave 15 percent headroom for inverter efficiency loss. Can I run this slow cooker for 8 hours on a 1500 Wh power station? Only if your power source can supply at least 210W continuous and 210W surge at 120V. | |||||

Generator Insights
With 12000 watts of surge capacity, this system can handle typical startup loads for central air compressors, well pumps, and other motor-driven equipment common in residential settings. The 6000-watt continuous rating supports sustained operation of multiple high-draw appliances simultaneously. The 6144 Wh capacity provides meaningful runtime for essential circuits during grid outages.
This unit uses lithium iron phosphate (LFP) chemistry, known for stable thermal behavior in stationary storage applications. The system is designed with internal protections typical of grid-tied and off-grid battery platforms. Source: EcoFlow DELTA Pro Ultra User Manual (manufacturer documentation).

Running load: 300 W. Surge: 300 W (resistive heating element). Voltage: 120 V AC required. Power station must supply clean AC output at this voltage and sustain 300 W continuous draw.
Expected Behavior
Estimated runtime: ~14.3h. Resistive load remains steady throughout the cook cycle. Usage over 6 hours per day consumes approximately 1800 Wh daily.
Field Note
Ensure at least 400 W inverter capacity for headroom. Verify power station supports multi-hour AC loads without thermal shutdown.
Frequently Asked Questions
Can the EcoFlow Delta Pro Ultra power a Slow Cooker?
Yes. The EcoFlow Delta Pro Ultra provides 6000W running / 12000W surge. The Slow Cooker needs 330W / 330W (including 10% buffer). That leaves 5670W of running headroom and 11670W of surge margin.
How long will the Delta Pro Ultra run a Slow Cooker?
Approximately 14.3 hours, based on the Slow Cooker's 300W draw and the Delta Pro Ultra's 6144Wh capacity (70% usable after real-world losses).
What Else Can You Run?
