In 2026, Anker SOLIX offers more hardware at 1kWh and 2kWh: the C1000 Gen 2 (about $500) out-specs the EcoFlow DELTA 3 (about $629) on output, solar input and weight for less money, and the C2000 Gen 2 takes 800W of solar to the DELTA 3 Max's 500W, though it now costs about $100 more. EcoFlow wins on the cheapest compact unit (RIVER 2 Pro, about $389) and on expansion and whole-home ecosystem.
How we compared them: Our picks are based on published specifications, pricing, warranty terms and owner reports.
The short answer
Buy Anker SOLIX if you want the strongest single unit for the price and do not plan to add batteries. Buy EcoFlow if you want a system that grows (DELTA 3 to 5kWh, DELTA 3 Max Plus to 10kWh, DELTA Pro Ultra to 90kWh) or you want the lightest, cheapest 768Wh station. The older matchups this page used to cover, the Anker C800 and F2000, have both been discontinued and replaced by the C800X and C2000 Gen 2.
Compact tier: Anker SOLIX C800X vs EcoFlow RIVER 2 Pro
| Spec | Anker SOLIX C800X | EcoFlow RIVER 2 Pro |
|---|---|---|
| Capacity | 768Wh LiFePO4 | 768Wh LiFePO4 |
| AC output | 1,200W (1,600W SurgePad) | 800W (1,600W X-Boost) |
| Solar input | 300W | 220W |
| Weight | About 24 lb (Amazon listing) | 18.2 lb |
| In the box | 100W folding panel included | Power station only |
| Price | About $430 with the panel | About $389 on Amazon ($369 at EcoFlow, sold out Oct 12) |
The RIVER 2 Pro is lighter and cheaper; the C800X has 50% more continuous output and more solar input, and the bundle includes a starter panel. For phones, laptops, a CPAP and lights, the RIVER 2 Pro is the better value. For a coffee maker or small microwave at camp, the C800X is the one that can do it.

1kWh tier: Anker SOLIX C1000 Gen 2 vs EcoFlow DELTA 3
| Spec | Anker SOLIX C1000 Gen 2 | EcoFlow DELTA 3 |
|---|---|---|
| Capacity | 1,024Wh | 1,024Wh |
| AC output | 2,000W (3,000W peak) | 1,800W (3,600W surge) |
| Solar input | 600W | 500W |
| Wall recharge | 49 min (1,600W) | 56 min (1,500W) |
| UPS | Under 10 ms | Under 10 ms |
| Weight | 24.9 lb | 27.6 lb |
| Expandable | No | To 5kWh |
| Price | About $600 | About $629 |
The C1000 Gen 2 wins every line except expansion. If you might add an extra battery for longer outages, the DELTA 3 (or the DELTA 3 Plus with 1,000W of solar input, about $719) is the one to buy; otherwise the Anker is the better deal. EcoFlow's non-expandable DELTA 3 Classic (about $499) costs about $50 less than the Anker but does not match its output or solar input.

2kWh tier: Anker SOLIX C2000 Gen 2 vs EcoFlow DELTA 3 Max
| Spec | Anker SOLIX C2000 Gen 2 | EcoFlow DELTA 3 Max |
|---|---|---|
| Capacity | 2,048Wh | 2,048Wh |
| AC output | 2,400W (4,000W peak) | 2,400W (4,800W surge, 3,400W X-Boost) |
| Solar input | 800W | 500W |
| Wall recharge | 1,800W; 58 min with AC plus solar | 0-80% in 68 min |
| UPS | 10 ms | 10 ms |
| Weight | 41.7 lb | 44.8 lb |
| Expandable | To 4kWh | DELTA 3 Max Plus version expands to 10kWh |
| Price | About $1,000 | About $899 |
The C2000 Gen 2 accepts 60% more solar and weighs 3 lb less; the DELTA 3 Max has the higher surge rating and costs about $100 less. If you want expansion beyond 4kWh on EcoFlow, step up to the DELTA 3 Max Plus (3,000W, expandable to 10kWh, about $1,199).

How long will each tier run a fridge?
Usable AC energy is about 85% of rated capacity: runtime (hours) = Wh x 0.85 / average load (W). For a full-size fridge averaging 150W, that is about 4.4 hours from 768Wh, 5.8 hours from 1,024Wh and 11.6 hours from 2,048Wh, whichever brand you choose.
The figures here use planning draws: a conservative 150W average for a full-size fridge (a new ENERGY STAR model averages closer to 63W, so expect longer runtimes).
About Anker SOLIX
Anker has made chargers and power banks since 2011 and sells its portable power stations under the SOLIX name. The current lineup runs from the 768Wh C800X to the 3,840Wh F3800 Plus with native 240V. Its recent models lean on high continuous output, fast wall charging and, at the top end, big solar inputs: 2,400W on the F3000 and 3,200W on the F3800 Plus.
About EcoFlow
EcoFlow, founded in 2017, has one of the widest ranges in the US market, from the 245Wh RIVER 3 to the DELTA Pro Ultra home system that scales to 90kWh. Its strength is expansion: the DELTA 3, DELTA 3 Plus, DELTA 3 Max Plus and DELTA 3 Ultra Plus accept extra batteries, and the Smart Home Panel line ties larger units into home circuits.
Where Anker SOLIX wins
- Output for the money at 1kWh: 2,000W vs 1,800W, for less money
- Solar input at every tier compared here: 300W vs 220W, 600W vs 500W, 800W vs 500W
- Weight at 1kWh and 2kWh
- High-voltage solar on the big units (165V inputs on the F3000 and F3800 Plus)
- Expansion per unit at 4kWh: the F3800 Plus reaches 26.9kWh, against 12kWh for one DELTA Pro 3 (36kWh across three units)
Where EcoFlow wins
- Compact value: the RIVER 2 Pro is about $80 cheaper and about 7 lb lighter than the C800X
- Expansion at 1kWh and 2kWh (DELTA 3 to 5kWh, DELTA 3 Max Plus to 10kWh, against 4kWh for Anker's C2000 Gen 2) and at the very top (DELTA Pro Ultra to 90kWh)
- Range: more models and more accessories, including smart home panels and generators
- Surge ratings on the DELTA 3 series (3,600W at 1kWh, 4,800W at 2kWh)
What about the big home-backup units?
At 3kWh and up, the matchups are the Anker SOLIX F3000 vs EcoFlow DELTA Pro (the F3000 is about $100 cheaper with more solar input) and the Anker F3800 Plus vs EcoFlow DELTA Pro 3 for native 240V (the Anker has more output for less money; the EcoFlow has a faster 10 ms UPS and expands further).
Which should you buy?
Buy Anker SOLIX if you want the best standalone 1kWh or 2kWh unit for the price, you charge from solar, or you want to carry it.
Buy EcoFlow if you want to start small and add batteries later, you want the cheapest and lightest 768Wh station, or you plan a whole-home system.

Frequently Asked Questions
Is Anker SOLIX better than EcoFlow?
At 1kWh and 2kWh, Anker's current models offer more for the money: the C1000 Gen 2 beats the DELTA 3 on output, solar input, weight and price, and the C2000 Gen 2 takes more solar than the DELTA 3 Max. EcoFlow is better if you want to add batteries later or want the cheapest compact unit.
Anker SOLIX C1000 Gen 2 vs EcoFlow DELTA 3: which is better?
The C1000 Gen 2 has 2,000W vs 1,800W of output, 600W vs 500W of solar input, weighs 24.9 lb vs 27.6 lb and costs less (about $500 vs $629). The DELTA 3 is expandable to 5kWh; the Anker is not.
Anker SOLIX C2000 Gen 2 vs EcoFlow DELTA 3 Max: which is better?
Both hold 2,048Wh and output 2,400W; the C2000 Gen 2 costs about $1,000 and the DELTA 3 Max about $899. The C2000 Gen 2 takes 800W of solar vs 500W and weighs 41.7 lb vs 44.8 lb. The DELTA 3 Max has a higher surge rating (4,800W vs 4,000W peak).
What replaced the Anker SOLIX C800 and F2000?
Both are discontinued in the US. The C800X replaces the C800 (same 768Wh and 1,200W, sold with a 100W panel for about $430), and the C2000 Gen 2 replaces the F2000 (same 2,048Wh and 2,400W at 41.7 lb, about $1,000).
Which brand is better for expanding capacity later?
At 1kWh and 2kWh, EcoFlow: the DELTA 3 and DELTA 3 Plus expand to 5kWh and the DELTA 3 Max Plus to 10kWh, while Anker's C2000 Gen 2 stops at 4kWh. At 4kWh Anker leads per unit, with the F3000 and F3800 Plus reaching 24kWh and 26.9kWh against 12kWh for one DELTA Pro 3 (36kWh across three). EcoFlow's DELTA Pro Ultra goes highest of all, to 90kWh.
Can Anker SOLIX charge from solar panels?
Yes. Solar input is 300W on the C800X, 600W on the C1000 Gen 2, 800W on the C2000 Gen 2, 2,400W on the F3000 and 3,200W on the F3800 Plus. Third-party panels work as long as they stay within each input's voltage limit.
How long will a 1kWh Anker or EcoFlow run a refrigerator?
About 5.8 hours for a full-size fridge averaging a conservative 150W, using 1,024Wh x 0.85 = 870Wh usable. A 2kWh unit roughly doubles that to about 11.6 hours.
