Which uses does each one qualify for?
The EcoFlow DELTA 3 Plus meets our requirements for 7 of 12 uses and the Anker SOLIX C1000 for 5. Each list's thresholds are explained on its page.
Which one recharges faster from solar?
At their limits, the EcoFlow DELTA 3 Plus refills in about 1.0 hours of strong sun and the Anker SOLIX C1000 in about 1.8. With smaller arrays the bigger battery takes longer.
Which costs less over its rated life?
The Anker SOLIX C1000 does: about $0.19 per kWh of rated lifetime storage against $0.20.
| EcoFlow DELTA 3 Plus | Anker SOLIX C1000 | |
|---|---|---|
| List price | $799 | $599.99 |
| Rated cycles | 4,000 | 3,000 |
| Lifetime energy | 4,096 kWh | 3,168 kWh |
| Cost per lifetime kWh | $0.20 | $0.19 |

Rated cycles are each maker's figure under its own test conditions, and capacity fades with age, so treat this as a comparison between the two, not a forecast.
How long does each last at a steady load?
At the same steady draw, the bigger battery lasts proportionally longer, until a load passes the smaller inverter's limit.
Which one recharges faster from the wall?
Wall charging decides how quickly you are ready again between outages or trips.
- EcoFlow DELTA 3 Plus: accepts up to 1,500 W from the wall and is rated to refill in about 56 minutes.
- Anker SOLIX C1000: accepts up to 1,300 W from the wall and is rated to refill in about 58 minutes.
How does each rank within its own size band?
A head-to-head can hide that both models are strong or weak for their size. The EcoFlow DELTA 3 Plus is ranked among 1,000–1,999 Wh models and the Anker SOLIX C1000 among 1,000–1,999 Wh models.

Can either one cover CPAP nights or go on a plane?
For a CPAP with a heated humidifier at ResMed's typical 56.1 W, the EcoFlow DELTA 3 Plus covers about 1.9 eight-hour nights and the Anker SOLIX C1000 about 2.0. Neither can fly: both are over the FAA's 160 Wh limit for passenger aircraft.
Without the humidifier a CPAP draws far less, so nights stretch well beyond these figures. See CPAP runtimes and flying with a power station.
Which one is easier to carry?
The EcoFlow DELTA 3 Plus is lighter by 0.8 lb. Watt-hours per pound shows which packs more battery for the weight.
- EcoFlow DELTA 3 Plus: 27.6 lb, 37 Wh per pound, 16 × 8.0 × 11 in.
- Anker SOLIX C1000: 28.4 lb, 37 Wh per pound, 14.8 × 8.07 × 10.5 in.
What do they share, and what isn't published?
They match on AC output, so those specs won't decide it. Not published: UPS switchover (Anker SOLIX C1000). Missing figures are never estimated, so a use that depends on one counts as unconfirmed.
Which should you pick for your use?
Where only one of them qualifies, the choice is made for you:
- Power stations that work as a UPS for computers and routers: the EcoFlow DELTA 3 Plus, because only it meets UPS switchover ≤ 30 ms.
- Best power stations for solar charging: the EcoFlow DELTA 3 Plus, because only it meets solar input ≥ 800 W.
When should you buy neither?
If one spec matters most, a similar-size model may beat both on it:
- Capacity: the Jackery Explorer 1000 Plus (1,264 Wh) beats both.
- AC output: the DJI Power 1000 (2,200 W) beats both.
- Surge: the DJI Power 1000 (4,400 W) beats both.
- AC charging: the Anker SOLIX C1000 Gen 2 (1,600 W) beats both.
- Rated cycles: the Jackery HomePower 1000 v2 (6,000) beats both.
- Weight: the Jackery HomePower 1000 v2 (23.4 lb) beats both.
