The numbers
| Battery capacity | 512Wh (LFP) |
|---|---|
| Usable energy | 435Wh (85% via AC outlets) |
| Continuous AC output | 500W |
| Surge rating | 1000W |
| Computer monitor running watts | 30W |
| Startup watts | 30W |
| Average draw | 30W |
| Estimated runtime | 15 hours |
| Energy per day of typical use | 240Wh |
512Wh × 0.85 = 435Wh usable ÷ 30W average = 14.5 hours

Recharging with solar
The EcoFlow River 2 Max accepts up to 220W of solar input. In real conditions that harvests about 825Wh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can keep up. A computer monitor uses about 240Wh a day at 8 hours of use, so with enough panels and good sun the EcoFlow River 2 Max can run it indefinitely.
Tips
- A 24–27 inch LED monitor uses 20–40W.
- You’ll still have about 470W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The EcoFlow River 2 Max uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
