The numbers
| Battery capacity | 245Wh (LFP) |
|---|---|
| Usable energy | 225Wh (92% via 12V/USB DC output) |
| Continuous AC output | 300W |
| Surge rating | 600W |
| Starlink Mini running watts | 30W |
| Startup watts | 40W |
| Average draw | 30W |
| Estimated runtime | 7.5 hours |
| Energy per day of typical use | 720Wh |
245Wh × 0.92 = 225Wh usable ÷ 30W average = 7.5 hours

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).
Solar can’t fully keep up. A Starlink Mini uses about 720Wh a day at 24 hours of use, more than the EcoFlow River 3’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- Starlink Mini runs on 12–48V DC and averages 25–40W, ideal for running straight from a DC or USB-C port.
- 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.
