The numbers
| Battery capacity | 245Wh (LFP) |
|---|---|
| Usable energy | 208Wh (85% via AC outlets) |
| Continuous AC output | 300W |
| Surge rating | 600W |
| E-bike battery | 500Wh |
| Energy per charge | 575Wh |
| Full charges | less than one full charge |
245Wh × 0.85 = 208Wh usable ÷ (500Wh × 1.15) = 0.4 charges

Recharging with solar
The EcoFlow River 3 accepts up to 110W of solar input. In real conditions that harvests about 413Wh on a sunny day (5 peak-sun hours).
Tips
- Most e-bike batteries are 400–750Wh. Their chargers draw 100–250W.
- The EcoFlow River 3 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
