The Anker Solix C1000 and EcoFlow Delta 3 Plus are arguably the two best power stations in the 1000Wh class in 2026. They match on capacity and output, but differ on price, weight, noise, and expandability. Picking between them comes down to what you prioritize.
Specs at a Glance
| Spec | Solix C1000 | Delta 3 Plus | |------|------------|--------------| | Capacity | 1,056Wh | 1,024Wh | | Output | 1,800W (2,400W surge) | 1,800W (2,700W surge) | | Weight | 30.9 lbs | 25.4 lbs | | AC Charge | ~58 minutes | ~56 minutes | | Solar Input | Up to 600W | Up to 500W | | Battery | LFP, 3,000+ cycles | LFP, 4,000+ cycles | | UPS | Yes, ~20ms | Yes, under 10ms | | Expandable | Yes (BP1000) | Yes (Delta 3 batteries) | | Warranty | 5 years | 5 years | | Price | $649 | $999 |
The Price Gap
The most striking difference is price. The Solix C1000 at $649 is $350 less than the Delta 3 Plus at $999. That is 35% cheaper for nearly identical capacity and output. The Anker frequently goes on sale under $500, widening the gap further.
For buyers on a budget, this gap is hard to ignore. You could buy the C1000 and a decent 200W solar panel for less than the Delta 3 Plus alone.
Charging Speed
Both charge impressively fast: 58 minutes for the Anker, 56 minutes for the EcoFlow. In practical use, the difference is negligible. Both can go from empty to full during a lunch break.
Solar input slightly favors the Anker at 600W versus 500W, though this only matters if you have a very large panel array.
Weight and Noise
The EcoFlow wins here convincingly. At 25.4 lbs, it is over 5 lbs lighter than the 30.9 lb Anker. The Delta 3 Plus is also significantly quieter, staying under 30dB at low-to-medium loads while the C1000 is noticeably louder.
For camping and portable use, those 5 lbs and the quieter fans add up.
UPS Performance
Both units offer UPS functionality, but the EcoFlow's sub-10ms switchover is faster than the Anker's approximately 20ms. For most devices, 20ms is fast enough. But for extremely sensitive equipment, the EcoFlow provides an extra margin of safety.
Expandability
Both support expansion batteries. The Anker's BP1000 ($599) brings total capacity to 2,112Wh. EcoFlow's expansion options are similarly priced. Neither has a significant advantage here.
Which Should You Buy?
Choose the Solix C1000 if:
- Value is your top priority
- You want the longest warranty in the class
- Solar input capacity matters (600W)
- Weight is not a major concern
Choose the Delta 3 Plus if:
- Noise levels matter (camping, bedroom use)
- You need the fastest possible UPS switchover
- You prefer a lighter unit for frequent transport
- You value the EcoFlow app ecosystem
There is no wrong choice here. The Anker delivers 95% of the EcoFlow experience at 65% of the price. The EcoFlow polishes the remaining 5% with better weight, noise, and UPS performance.
