The numbers
| Battery capacity | 268Wh (LFP) |
|---|---|
| Usable energy | 228Wh (85% via AC outlets) |
| Continuous AC output | 600W |
| Surge rating | 1200W |
| Aquarium heater (100W) running watts | 100W |
| Startup watts | 100W |
| Average draw | 40W |

Recharging with solar
The Bluetti EB3A accepts up to 200W of solar input. In real conditions that harvests about 750Wh on a sunny day (5 peak-sun hours).
Solar can’t fully keep up. An aquarium heater (100W) uses about 960Wh a day at 24 hours of use, more than the Bluetti EB3A’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- Aquarium heaters cycle with their thermostat. Add an air pump (5–10W) to keep fish oxygenated during an outage.
- You’ll still have about 500W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Bluetti EB3A uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
