How long will an EcoFlow RIVER Pro run a monitor, 27 inch?
About 12 hours — 12 h 23 min typically, from 11 h 40 min in the worst case to 13 h 7 min at best. That assumes a monitor, 27 inch pulling 30 W continuously, plus the station's 10 W AC mains socket overhead — 40 W in total out of 496 usable watt-hours.
Backlight brightness is nearly the whole figure.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × monitor, 27 inch, UK 230 V | 40 W | 11 h 40 min | 12 h 23 min | 13 h 7 min |
| 2 × monitor, 27 inch, UK 230 V | 70 W | 6 h 40 min | 7 h 5 min | 7 h 30 min |
| 1 × monitor, 27 inch, US 120 V | 40 W | 11 h 40 min | 12 h 23 min | 13 h 7 min |
- 1.6 nights of eight hours, or 0.52 days of continuous running.
- Usable energy: 496 Wh of the 720 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 1,321 Wh of rated capacity — 1.8× this station.
- Start-up: the monitor, 27 inch asks for 30 W at switch-on against this station's 1,200 W peak — comfortable.
