Solar Station for a Beach Day: What You Actually Need
Short answer: For a beach day, you need to power phones, a bluetooth speaker, possibly a portable fan, and a small cooler. Total consumption is typically 100–400 Wh. A 500–800 Wh solar generator covers a full day with margin. You don’t need anything larger — bigger units are heavier than necessary and overkill for this use case.
Beach Day Power Loads
| Load | Watts | Hours | Total Wh |
|---|---|---|---|
| Phone charging ×4 | 25W | 2h | 50 Wh |
| Bluetooth speaker | 15W | 6h | 90 Wh |
| Portable fan | 30W | 4h | 120 Wh |
| Tablet | 20W | 3h | 60 Wh |
| Mini cooler (20L) | 55W | 6h (40% duty) | 132 Wh |
| Total | ~452 Wh |

Honest Recommendation
For a standard beach day without a mini cooler, the EcoFlow River 2 (256 Wh, 3.5 kg) covers everything and is genuinely portable. If you want the cooler running all day, step up to the Bluetti EB70S (716 Wh) for comfortable margin. Don’t buy a 1,000+ Wh unit for beach use — you’re carrying extra weight and paying for capacity you won’t use.
