Anker’s SOLIX F2000 and EcoFlow’s DELTA 2 Max both store 2,048Wh in LiFePO4 cells and both run 2,400W of continuous AC, according to Anker’s F2000 datasheet and EcoFlow’s U.S. spec page. The similarities end at the scale. Anker’s F2000, first sold as the PowerHouse 767, weighs 67.2 pounds and rolls on wheels. EcoFlow’s DELTA 2 Max weighs 50 pounds, takes up to two extra batteries for 6,144Wh, and was listed at $1,049 on EcoFlow’s U.S. store on Oct. 17, 2026. Here’s how the two compare on power, charging, expansion and portability, and which makes more sense for your setup.

F2000 figures come from Anker’s A1780 datasheet (U.S. values). DELTA 2 Max figures come from EcoFlow’s U.S. product and spec page. I haven’t run capacity tests on either unit, so runtime and charging examples are my estimates. You can check the current EcoFlow DELTA 2 Max listing on Amazon. When I checked in October 2026, Anker’s U.S. F2000 page pointed to its newer SOLIX C2000 Gen 2, and I didn’t find a current F2000 listing on Amazon U.S.
The Short Answer
- Pick the EcoFlow DELTA 2 Max if you want the lighter box, six AC outlets, room to grow to 6,144Wh, X-Boost for heaters and kettles, and a model you can buy new today.
- Pick the Anker SOLIX F2000 if you find one at a good price and you want a wheeled station with a TT-30 RV outlet, three 100W USB-C ports and two car outlets.

Power: Same Continuous Rating, More Headroom on the DELTA 2 Max
At 2,400W continuous, both stations run a microwave, coffee maker, space heater, window AC or most corded power tools one at a time. The gap is on the peaks. EcoFlow rates the DELTA 2 Max for a 4,800W surge, compared with 2,800W for the F2000, which helps when a compressor or pump motor kicks on while other loads are running.
EcoFlow’s X-Boost mode also lets the DELTA 2 Max run resistive devices rated up to 3,400W, like a hair dryer or a big kettle, by lowering the voltage slightly. Heating elements tolerate that, so the device runs at reduced power instead of tripping the inverter. For more on reading surge ratings, see my guide to surge watts vs running watts.
Ports: Six AC Outlets vs an RV Outlet
The DELTA 2 Max has six AC outlets, which covers a fridge, freezer, router, lamp, TV and phone charger without a power strip. EcoFlow lists 15 outputs in total.
The F2000 has four AC outlets plus a TT-30R. That’s the 30A RV plug, so you can run a travel trailer’s shore cord straight into the station, within its 2,400W limit. It also has more USB-C power, with three 100W ports, and two 120W car outlets for 12V fridges or tire inflators.
| If you mostly run… | Better fit |
|---|---|
| Household appliances in an outage | DELTA 2 Max (six AC outlets) |
| An RV through its shore cord | F2000 (TT-30R) |
| Several laptops at once | F2000 (three 100W USB-C) |
| Small 12V gear like LED strips and routers | DELTA 2 Max (car outlet plus two DC5521) |
Charging Speed
From the wall
The DELTA 2 Max charges at up to 1,800W through EcoFlow’s X-Stream input. The F2000 takes up to 1,440W, which Anker says reaches 80% in about an hour. By my math, the DELTA 2 Max’s higher input gets it from empty to 80% (about 1,640Wh) in roughly an hour as well, and to full a bit sooner than the F2000.
From solar
Both top out at 1,000W of solar. The difference is how you wire it. The DELTA 2 Max has two solar ports at 500W each, rated 11–60V and 15A. The F2000 has one input that accepts 11–32V at up to 10A or 32–60V at up to 20A.
Worked example: four 200W panels (estimate)
Take four portable 200W panels with an open-circuit voltage around 24V and about 10A short-circuit current each.
- DELTA 2 Max: two panels in series per port (about 48V, 10A) gives about 400W into each port, or 800W total, well under each port’s 500W cap and 60V limit.
- F2000: two series pairs wired in parallel (about 48V, 20A) gives up to about 800W into its single input, inside the 32–60V, 20A window.
In good sun with real-world losses, either setup could make about 600W, refilling about 2kWh in roughly 3.5 hours. Cold mornings raise panel voltage, so leave margin under each 60V limit.
Expansion and Home Backup
The DELTA 2 Max supports up to two extra batteries, either the DELTA 2 Max Smart Extra Battery or the older DELTA Max Smart Extra Battery. With two of the 2,048Wh DELTA 2 Max batteries, you get 6,144Wh. It also works with EcoFlow’s Smart Generator and the 800W Alternator Charger, according to EcoFlow’s spec page.
The F2000 accepts one 2,048Wh expansion battery, for 4,096Wh total.
| Setup | Capacity | Fridge + router + lights at 150W average (estimate) |
|---|---|---|
| Either station alone | 2,048Wh | ~12 hours |
| F2000 + 1 battery | 4,096Wh | ~23 hours |
| DELTA 2 Max + 1 battery | 4,096Wh | ~23 hours |
| DELTA 2 Max + 2 batteries | 6,144Wh | ~35 hours |
Estimates: capacity × 0.85 for inverter losses ÷ 150W. Solar recharging during the day stretches these.
Portability: 17 Pounds Apart
The F2000 weighs 67.2 pounds. Anker gave it a suitcase-style pull handle and wheels, which work well on a garage floor, driveway or campground path. Lifting it into a truck bed is a two-person job.
The DELTA 2 Max weighs 50 pounds and is about 3.5 inches shorter. It has two fixed handles and no wheels, so you carry it, but one strong adult can manage a short trip from the house to the car.
Worked Example: A Weekend RV Trip (estimate)
Say you run a 12V fridge (about 600Wh a day), a CPAP (about 300Wh a night), a coffee maker for 10 minutes (about 170Wh) and charge two laptops (about 150Wh). That’s about 1,220Wh a day.
- Either station covers one full day with about 500–600Wh to spare after losses.
- With 600W of solar for five hours, you’d add about 3,000Wh, so both could keep going all weekend.
- The F2000’s TT-30R lets you plug the trailer’s shore cord in directly. With the DELTA 2 Max, you’d use a TT-30 to 5-15 adapter and stay within one 15A outlet’s limit.
Which One Should You Buy?
For most buyers shopping new, the EcoFlow DELTA 2 Max is the more practical pick. It’s lighter, has more AC outlets, more surge headroom, faster wall charging and room to grow to 6,144Wh. If you’re specifically outfitting an RV and you find an F2000, its wheels, TT-30R outlet and three 100W USB-C ports are real advantages.
If you’re leaning Anker, its current 2kWh model is covered in my Anker SOLIX C2000 Gen 2 vs F2000 comparison and C2000 Gen 2 review. For EcoFlow’s newer generation, see Delta 3 Max vs Delta 3 Max Plus vs Delta 2 Max.
