|---|---|
| Usable energy | 225Wh (92% via 12V/USB DC output) |
| Continuous AC output | 300W |
| Surge rating | 600W |
| Laptop battery | 60Wh |
| Energy per charge | 69Wh |
| Full charges | 3.3 charges |
245Wh × 0.92 = 225Wh usable ÷ (60Wh × 1.15) = 3.3 charges

Tips
- A typical laptop battery holds 50–70Wh. Charging over USB-C PD is more efficient than using the laptop's AC brick.
- Running it from the EcoFlow River 3’s DC port instead of the AC outlet avoids inverter losses: about 17Wh more usable energy.
- The EcoFlow River 3 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
