Our Review
A 2,048Wh step up from the Delta 2 with the same excellent app and X-Boost, lighter than most 2kWh rivals at 50 lbs — the app-lover's mid-capacity pick.
Specifications
| Capacity | 2048 Wh |
|---|---|
| Continuous output | 2400 W |
| Surge output | 3100 W |
| Battery chemistry | LiFePO4 |
| Cycle life (to 80%) | 3000 cycles |
| AC recharge | 81 min |
| Max solar input | 1000 W |
| Weight | 50 lbs |
The Delta 2 Max takes everything that makes the Delta 2 a strong pick and doubles the capacity to 2,048Wh, with output up to 2,400W (3,100W surge). It keeps EcoFlow's best-in-class app — live power monitoring, charge-rate control, outlet timers — and X-Boost for running high-wattage resistive gear.
At 50 lbs it's notably lighter than most 2kWh stations (the Bluetti AC200L and Jackery 2000 Plus are ~62 lbs), which matters if you move it between vehicle and campsite. The 3,000-cycle battery is solid if not class-leading, and the 1,000W solar input is good rather than exceptional.
Pros
- 2,048Wh with the best app in the category
- 50 lbs — light for a 2kWh station
- X-Boost for high-wattage resistive devices
- Expandable with add-on batteries
Cons
- 3,000 cycles — beaten by the AC200L's 3,500
- 81-minute recharge is mid-pack
- Lower surge (3,100W) than some rivals
Who it's for: people who loved the Delta 2's software but need double the runtime. If longevity per dollar matters more than the app, weigh the Bluetti AC200L (currently $748.99).
