Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: Dell P2722H (55W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| LG 27UL500-W | 41W | 41W | Safe | ~4.2h | OEM Manual |
Show expert analysisTechnical: **Running load:** 41 W. **Surge load:** 41 W. **Voltage requirement:** 120 V AC. No inrush current. Assumes resistive load profile typical of LED-backlit displays. Field note: Verify power station output is clean enough for electronics. Inadequate waveform may cause screen flicker or shutdown. Can I run this monitor on a 300W power station? Only if your power source can supply at least 41W continuous and 41W surge at 120V. Confirm output waveform quality before connecting sensitive electronics. | |||||
| Samsung SE370 27-inch | 35W | 35W | Safe | ~4.9h | OEM Manual |
Show expert analysisTechnical: **Running load:** 35 W. **Surge:** 35 W. **Voltage:** 120 V AC. No surge overhead, resistive load. A power station rated for 100 W continuous at 120 V AC meets the electrical requirement. Field note: Leave at least 15 W headroom above 35 W to account for inverter efficiency loss and avoid nuisance shutdowns during prolonged operation. Will this monitor run on any portable power station? Only if your power source can supply at least 35W continuous and 35W surge at 120V. | |||||
| Dell P2722H | 55W | 55W | Safe | ~3.1h | OEM Manual |
Show expert analysisTechnical: **Running load:** 55 W. **Surge:** 55 W (no startup spike). **Voltage:** 120 V AC. Low continuous draw with zero inrush makes pairing straightforward provided the power station supplies clean 120 V output. Field note: Verify the power station inverter remains cool during multi-hour sessions. Minimal headroom required. Can I run this monitor on a 300 W power station? Only if your power source can supply at least 55W continuous and 55W surge at 120V. Check manufacturer specs for sustained load limits. | |||||

Generator Insights
The 600W surge rating can handle typical startup loads from small compressor-driven appliances like mini fridges and air tools. It can support motor-driven devices that require momentary inrush current during ignition. At 245Wh total capacity, expect limited runtime on continuous loads near the 300W ceiling.
LFP chemistry provides stable operation under load cycling. The unit accommodates brief inrush events up to 600W for equipment startup. Source: EcoFlow RIVER 3 User Manual v1.0 (manufacturer documentation).

Frequently Asked Questions
Can the EcoFlow RIVER 3 power a Monitor?
Yes. The EcoFlow RIVER 3 provides 300W running / 600W surge. The Monitor (27-inch LCD) needs 64W / 64W (including 15% buffer). That leaves 236W of running headroom and 536W of surge margin.
How long will the RIVER 3 run a Monitor?
Approximately 3.1 hours, based on the Monitor (27-inch LCD)'s 55W draw and the RIVER 3's 245Wh capacity (70% usable after real-world losses).
What Else Can You Run?
With 180W allocated to the Monitor (27-inch LCD), the RIVER 3 still has ~5W of margin. These devices could run simultaneously:
