Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: Frigidaire FFFU16F2VW (16 Cu. Ft. Upright, Auto-Defrost) (320W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| GE FUF17DLRWW (17.3 Cu. Ft. Upright, Frost-Free, Garage Ready) | 153W | 306W | Safe | ~2.3h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 153W estimated from 441 kWh/yr at 0.33 duty cycle. **Estimated startup surge:** 306W at 2.0x running (conservative — no OEM LRA published). **Voltage:** 120V AC. Frost-free upright with electronic temperature control and garage-ready certification (0°F to 110°F ambient). Field note: Garage-ready certification means this freezer has an internal heater that activates in cold ambient conditions to keep the compressor warm. In winter garage use on battery power, energy consumption may increase — counter-intuitive but important for sizing. The 20A on the spec sheet is the circuit breaker requirement, not the actual draw. Can a portable power station keep this GE upright freezer running during an outage? At 153W running with 306W estimated surge, most power stations above 500W continuous can handle this freezer. A 1,000 Wh battery provides roughly 14 hours of runtime at average draw. | |||||
| Frigidaire FFFU16F2VW (16 Cu. Ft. Upright, Auto-Defrost) | 160W | 320W | Safe | ~2.2h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 160W estimated from 461 kWh/yr at 0.33 duty cycle. **Estimated startup surge:** 320W at 2.0x running (conservative — no OEM LRA published). **Voltage:** 120V AC. Auto-defrost upright with wire shelving and R-600A refrigerant. Field note: The Frigidaire is the most affordable option but also the least efficient at 461 kWh/yr. For extended outage use on battery power, the extra ~55 Wh/day versus the GE upright adds up over multi-day events. Not garage-rated — performance may degrade in unheated spaces below 55°F. How long can a portable power station run this Frigidaire freezer? At 160W running with 320W estimated surge, a 1,000 Wh power station provides roughly 13 hours at average draw. For a full 24-hour outage, budget at least 1,300 Wh of usable station capacity. | |||||
| GE FCM16DLWW (15.7 Cu. Ft. Chest, Manual Defrost, Garage Ready) | 127W | 254W | Safe | ~2.8h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 127W estimated from 277 kWh/yr at 0.25 duty cycle. **Estimated startup surge:** 254W at 2.0x running (conservative — no OEM LRA published). **Voltage:** 120V AC. Manual-defrost chest freezer with top-opening lid and garage-ready certification (0°F to 110°F ambient). Field note: This is the most power-station-friendly freezer in the set. Manual defrost means no surprise heater cycles draining the battery. The chest design retains cold for 36-48 hours without power if kept closed — buying critical time during extended outages. Garage-ready certification adds a compressor heater for cold ambient, but in summer outage scenarios it stays dormant. Why is the chest freezer so much more efficient on battery power? Three reasons: top-opening lid prevents cold air from falling out when opened, thicker insulation reduces heat gain, and manual defrost eliminates the periodic 400-600W heater cycle that upright auto-defrost models run every 12-24 hours. | |||||

Generator Insights
The 1000W surge can handle typical compressor startup events in refrigerators, window AC units, and well pumps that fall within momentary draw limits. Sustained loads must stay at or below 500W to avoid shutdown. This is a light-duty unit for essential circuits, not whole-home backup.
This portable station uses LFP chemistry, known for thermal stability in consumer lithium batteries. The 512Wh capacity and 500W continuous rating provide a workable buffer for appliances within spec. Source: EcoFlow RIVER 2 Max User Manual v1.0 (manufacturer documentation).

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
Running range: 127W to 160W depending on freezer type and efficiency rating. Estimated surge range: 254W to 320W at 2.0x running (conservative — no freezer manufacturer publishes LRA). Voltage: 120V AC. Chest freezers draw significantly less than uprights due to superior insulation and manual defrost.
Expected Behavior
Estimated runtime: ~2.2h. Freezers run 24 hours per day with intermittent compressor cycling. Daily energy consumption ranges from 759 Wh (chest manual-defrost) to 1,263 Wh (upright auto-defrost). Compressor duty cycle varies from ~25% (chest) to ~33% (upright frost-free).
Field Note
For emergency power planning, freezer type matters more than size. A 15.7 Cu. Ft. chest freezer uses 40% less energy than a 16 Cu. Ft. upright — and holds cold 36-48 hours without power if kept closed. Garage-ready models have internal heaters that increase winter consumption on battery power.
Frequently Asked Questions
Can the EcoFlow RIVER 2 Max power a Full-Size Freezer?
Yes. The EcoFlow RIVER 2 Max provides 500W running / 1000W surge. The Full-Size Freezer (15-17 Cu. Ft.) needs 200W / 400W (including 25% buffer). That leaves 300W of running headroom and 600W of surge margin.
How long will the RIVER 2 Max run a Full-Size Freezer?
Approximately 2.2 hours, based on the Full-Size Freezer (15-17 Cu. Ft.)'s 160W draw and the RIVER 2 Max's 512Wh capacity (70% usable after real-world losses).
What Else Can You Run?
With 230W allocated to the Full-Size Freezer (15-17 Cu. Ft.), the RIVER 2 Max still has ~10W of margin. These devices could run simultaneously:
