EcoFlow DELTA Pro 3 vs Anker SOLIX F3800
Both are top-tier, whole-home-class stations with 240V output and multi-kW continuous ratings, aimed at buyers who want to run large circuits or several major appliances at once rather than a single essential. This is a decision between two premium options, not a budget comparison.
These picks are focused on the U.S. market. Before buying, confirm plug type, voltage (120V), warranty terms, and regional availability on the Amazon listing.

Quick summary
- EcoFlow DELTA Pro 3 leads on capacity (wh) (4,096 Wh vs 3,840 Wh).
- Anker SOLIX F3800 leads on rated continuous output (6,000 W vs 4,000 W).
- Anker SOLIX F3800 leads on surge / peak output (9,000 W vs 8,000 W).
A use case below only names a model as ahead when at least two independent, comparable fields agree (or the use case is defined by a single field, like solar charging). A single distinguishing field in an otherwise-tied or unverified category is named specifically, not counted as winning that use case.

Spec comparison
Reused directly from the same catalog and winner-highlighting logic as the general Compare page. A blank or “Not verified” cell means the data isn’t on file — it is never treated as zero, and a difference is only highlighted when both values are actually known.

Winner by use case
Each verdict below is derived only from the specific fields listed as criteria — never from overall impressions, and never from physical testing. A null field is neither a win nor a loss for either unit, and a category needs at least two independent fields to agree before it declares an overall winner (a category built around a single criterion, like solar charging, is the exception).
Refrigerator backup
EcoFlow DELTA Pro 3 edges ahead here.
Criteria: Capacity (Wh), Surge / peak output, Idle consumption, Solar input (max) (3 of 4 comparable).
RV / van life
Anker SOLIX F3800 edges ahead here.
Criteria: Rated continuous output, Surge / peak output, RV TT-30 outlet, Expandable (4 of 4 comparable).
Camping
No clear overall winner based on the data on file.
EcoFlow DELTA Pro 3 has the higher solar input (max) among the data available, but weight and energy per kg (wh/kg) and idle consumption are not verified for one or both units.
Criteria: Weight, Energy per kg (Wh/kg), Idle consumption, Solar input (max) (1 of 4 comparable).
Home outage essentials
No clear overall winner based on the data on file.
Criteria: Capacity (Wh), Rated continuous output, Native 120/240V, UPS switchover, Expandable (4 of 5 comparable).
Solar charging
EcoFlow DELTA Pro 3 edges ahead here.
Criteria: Solar input (max) (1 of 1 comparable).
Portability
No clear overall winner based on the data on file.
Criteria: Weight, Energy per kg (Wh/kg) (0 of 2 comparable).
Estimated autonomy
Calculated the same way as each product page’s runtime table: capacity_wh × 0.85 ÷ device_watts. These are planning estimates, not lab measurements or guarantees.
| Example load | EcoFlow DELTA Pro 3 | Anker SOLIX F3800 |
|---|---|---|
| Refrigerator (full size) (~150 W) | 23.2 h | 21.8 h |
| CPAP machine (no humidifier) (~40 W) | 87 h | 81.6 h |
| LED lights (a few rooms) (~40 W) | 87 h | 81.6 h |
Why your real result may differ
These figures are planning estimates from the inputs and assumptions above — not a lab measurement. Your real result can vary with:
- Temperature — cold reduces usable battery capacity; heat can trigger throttling
- Battery age and condition — capacity fades gradually with cycles and time
- Inverter efficiency — some energy is always lost converting DC to AC
- Variable appliance draw — most appliances don't pull a constant wattage
- Startup/surge power — a motor's brief startup spike can exceed its running watts
- Appliance settings — e.g. humidifier, fan speed, or temperature setting
- Conversion losses beyond the modeled efficiency assumption
- Real solar conditions — actual panel output is usually well below its rated watts
- The safety reserve is a margin for error, not a guarantee
Pros & limitations
From each product’s existing catalog entry — no personal impressions, noise, build-quality or real-world behavior is added here.

Conclusion
EcoFlow DELTA Pro 3 has the higher capacity (wh) and solar input (max) on file. Anker SOLIX F3800 has the higher rated continuous output and surge / peak output on file.
Weight, Dimensions, Warranty (stated) are not verified for the EcoFlow DELTA Pro 3. Dimensions is not verified for the Anker SOLIX F3800. With those gaps, there is no absolute winner between these two units based on the data currently on file.
If refrigerator backup or rv / van life or solar charging matters most to you, the EcoFlow DELTA Pro 3 has the edge on file for refrigerator backup; the Anker SOLIX F3800 has the edge on file for rv / van life; the EcoFlow DELTA Pro 3 has the edge on file for solar charging. For the other use cases evaluated above, the data on file doesn’t support picking one unit over the other — check which specific criteria matter for your situation.
Neither unit has been physically tested by PowerMatchLab. Before buying, enter your own devices in the Power Calculator — the numbers above use example loads, and your real appliances may draw differently.
