Performance & Testing
🔋 Battery Capacity Test
- Claimed: 2400Wh
- Real-World: 2080Wh (86.6% efficiency) in our tests
- Cycle Life: 2500+ cycles at 80% capacity
⚡ Load Test Results
| Appliance | Runtime |
|---|---|
| CPAP Machine | 32+ hours |
| 5000 BTU AC | 3-4 hours (or all day with solar input) |
| Laptop (60Wh) | 33 full charges |
| LED Lights (10W) | 200+ hours |
- Peak Performance: Handled 1200W surge (15A table saw briefly)
☀️ Solar Charging
- 300W Solar Input: 8.4 hours to full
- 500W Solar Input: 5-5.5 hours (with MPPT efficiency boost)
Design & Usability
Pros:
✅ Compact for 2400Wh (suitcase-style, easy to move)
✅ Durable aluminum shell (survives road vibrations)
✅ Pure sine wave inverter (safe for sensitive electronics)
✅ 12V regulated output (stable voltage for RV/car devices)
Cons:
❌ Only 1000W inverter (underpowered for the battery size)
❌ No Anderson port (uses barrel plug for solar input)
❌ Slow AC charging (14.6 hours with included 200W adapter)
Who Should Buy It?
Best For:
- RV owners needing silent, solar-ready power
- Off-grid cabins (runs fridges, lights, WiFi)
- Preppers wanting long-term battery storage
Skip If You Need:
- Heavy-duty tools (requires 1500W+ inverter)
- Fast AC charging (no 400W+ adapter included)
Final Verdict: 8.5/10
The Bluetti EB240 excels as a portable, high-capacity solar generator but is held back by its small inverter. Ideal for low-wattage off-grid living, but not for power-hungry appliances.
