What stands out
Charging speed
The 1,000W AC input is class-leading. Most competitors in this price range charge at 300–600W. The Delta 2 goes from empty to 80% in under an hour — practical for charging during a lunch stop at a library or café.
LFP battery chemistry
EcoFlow switched the Delta 2 to LiFePO4 (LFP) cells, which is significant. LFP is the same chemistry in quality van house batteries — thermally stable, long cycle life (3,000 cycles vs 500–800 for NMC), and much safer. The Delta 2 should last 8–10 years of regular use, not the 2–3 years typical of NMC power stations.
Expandable capacity
An extra battery (Delta 2 Extra Battery, 1,024Wh) can be connected to double capacity to 2,048Wh. This modular approach lets you start with 1,024Wh and expand if you need more.
AC output (1,800W)
Handles almost everything except large air conditioners and high-power kitchen appliances. Induction cooktop on a low setting, laptop, phone, fan — all simultaneously.
Real-world camping performance
A typical day's load with the Delta 2:
- 12V compressor fridge (50W avg): 24h = 1,200Wh — exceeds Delta 2 capacity alone
- 12V fridge for 12 hours: 600Wh
- Laptop (65W, 4h): 260Wh
- Phone charging (2×): 30Wh
- Fan (20W, 8h): 160Wh
Bottom line: For camping or weekend van life without a separate house battery system, a Delta 2 alone lasts 12–16 hours of typical loads before needing recharge. With 200W of solar in good conditions, you can roughly sustain weekend use.
For full-time van life, the Delta 2 needs daily solar or AC recharging to keep up with a 12V fridge running 24/7.
Delta 2 vs Delta 2 Max
| Delta 2 | Delta 2 Max | |
|---|---|---|
| Capacity | 1,024Wh | 2,048Wh |
| AC output | 1,800W | 2,400W |
| Weight | 27.9 lbs | 50 lbs |
| Price | ~$750 | ~$1,200 |
Buy Delta 2 if: Weekend camping, occasional van use, budget under $900. Buy Delta 2 Max if: Full-time van life, running a 12V fridge 24/7, want 2+ days of autonomy.
