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 — the AC200L's pack is rated for 3,500 — and its 3,100W surge trails the AC200L's 3,600W. The 1,000W solar input is good rather than exceptional, but its 81-minute AC recharge beats both the AC200L's 90 and the Jackery Explorer 2000 Plus's 120.
Pros
- 2,048Wh with the best app in the category
- 50 lbs — light for a 2kWh station
- X-Boost for high-wattage resistive devices
- 81-minute AC recharge — faster than the AC200L or Explorer 2000 Plus
Cons
- 3,000 cycles — beaten by the AC200L's 3,500
- 3,100W surge trails the AC200L's 3,600W
What it actually runs
A full 2,048Wh charge gives about 1,740Wh usable:
| Device | Typical draw | Runtime per charge |
|---|---|---|
| Full-size fridge | ~65W avg | ~27 hours |
| CPAP (humidifier on) | 60W | ~29 hours (3.5 nights) |
| Space heater | 1,500W | ~1.1 hours |
| Microwave | 1,000W | ~1.7 hours total |
| Mini-fridge | ~40W avg | ~43 hours |
EcoFlow's app shows the live draw of whatever you plug in, so you can confirm these numbers for your own gear before a trip.
Can the Delta 2 Max run a space heater?
Yes, up to its 2,400W limit (X-Boost extends this for resistive heaters), but a 1,500W heater drains the battery in about an hour — power stations suit short heat bursts, not all-night heating.
Will it keep a fridge cold overnight?
Easily — about 27 hours on a full-size fridge, so a single charge covers a full night and most of the next day.
Who it's for: people who loved the Delta 2's software but need double the runtime. Availability note: the Delta 2 Max currently has no first-party Amazon offer (as does its closest rival, the Bluetti AC200L). In stock instead: the Jackery Explorer 2000 Plus (currently $899.00) in the same class, or the EcoFlow Delta 2 if half the capacity covers your loads.
