PORTABLE POWER · BUYING DECISIONS
Power stations around 1 kWh: four ways to choose
Similar battery size does not mean the same fit. Start with your load, then decide how much carrying weight and charging flexibility you need.
The short answer
Anker C1000 Gen 2 offers the highest listed continuous output in this four-model group. Jackery Explorer 1000 v2 has the lowest listed weight. Neither distinction establishes the longest real-world runtime.
| Specification | Anker SOLIX C1000 Gen 2 | BLUETTI Elite 100 V2 | EcoFlow DELTA 3 Plus | Jackery Explorer 1000 v2 |
|---|---|---|---|---|
| Nominal capacity | 1,024 Wh | 1,024 Wh | 1,024 Wh | 1,070 Wh |
| Rated continuous output | 2,000 W | 1,800 W | 1,800 W | 1,500 W |
| Listed weight | 24.9 lb | 25 lb | 27.6 lb | 23.8 lb |
| US price snapshot | Not captured | $479 | Not captured | $559 |

What these numbers change
The three 1,024 Wh models start with the same nominal stored energy; Jackery lists 1,070 Wh. The extra 46 Wh is about 4.5%, calculated against 1,024 Wh. That is a much smaller difference than the gap between a 1,500 W and a 2,000 W inverter, but the two measures answer different questions: energy budget versus load compatibility.
For a laptop-and-router setup, carrying weight and suitable DC ports may matter more than unused AC output. For several appliances, add their simultaneous running demand and check startup requirements separately. These are decision examples, not tested device combinations.
Decide on expansion before choosing a generation
Anker explicitly states that C1000 Gen 2 cannot add expansion-battery capacity. Do not carry over the original C1000’s expansion capability just because the names are similar. EcoFlow lists supported extra-battery models for DELTA 3 Plus; confirm the precise battery and cable combination, not just the brand.
If your measured energy requirement already exceeds this class, buying a smaller unit because an upgrade might exist later can be a false saving. Price the complete system you need now, including the extra battery and connection hardware.
Charging is a separate shortlist
Anker lists up to 600 W solar input, BLUETTI Elite 100 V2 up to 1,000 W, and DELTA 3 Plus two 500 W inputs. Those are input ceilings, not energy guarantees. A higher ceiling is useful only with a compatible panel arrangement and enough actual sunshine. Compare the voltage and current limits before panel wattage.
Before buying
Confirm the US model, supported loads, connector requirements and delivered price. This table excludes temporary prices so an unobserved offer does not decide the recommendation. Use the backup-energy calculator for a transparent capacity screen; it will not check inverter startup or appliance compatibility.
