EcoFlow DELTA 3 vs Anker SOLIX C1000 Gen 2 vs Jackery Explorer 1000 v2
All three boxes hold about 1,000 watt-hours, so they run a fridge for about 7 to 8 hours by our math. They differ in output, weight, outlets, extra batteries, and warranty, and this guide shows each one from the makers' own numbers.
All three boxes hold about 1,000 watt-hours, so they run a fridge for about 7 to 8 hours by our math. They differ in output, weight, outlets, extra batteries, and warranty, and this guide shows each one from the makers' own numbers. Watts: how fast something uses power. Watt-hours: how much power a box holds.
The three boxes side by side
The BLUETTI Elite 100 V2 is also in this size. It is not in this guide, so see its sheet.
These numbers come from each maker's own page. "We're checking" means we do not have a maker number yet.
| Spec | EcoFlow DELTA 3 | Anker SOLIX C1000 Gen 2 | Jackery Explorer 1000 v2 |
|---|---|---|---|
| Holds | 1,024 Wh | 1,024 Wh | 1,070 Wh |
| Output | 1,800 W | 2,000 W | 1,500 W |
| Surge | 3,600 W | 3,000 W | 3,000 W |
| Weight | 27.6 lb | 24.9 lb | 23.8 lb |
| AC outlets | 6 | 5 | 3 |
| USB-C | 100 W | 140 W | 100 W |
| Switch-over time | 10 ms | 10 ms | 20 ms |
| Extra batteries | Yes, up to 5 kWh total | No, says Anker | We're checking |
| Warranty | 5 years | 5 years | 3 years |
Surge: a short burst some things need to start. Switch-over time: how fast the box takes over when the wall power stops. Smaller is faster.
Life of the battery
A cycle is one full charge and use. Each maker lists how many cycles the box takes before it falls to a set share of its first size, 80% or 70%. The makers use different cut-offs, so read them with care.
| Box | Cycles listed |
|---|---|
| EcoFlow DELTA 3 | 4,000 cycles, to 80% or more of its size |
| Anker SOLIX C1000 Gen 2 | At least 80% of its size after 4,000 cycles |
| Jackery Explorer 1000 v2 | 4,000 cycles, to 70% or more of its size |
Jackery counts down to 70% and the others to 80%, so the three numbers are not the same test. LiFePO4 is a type of battery. The DELTA 3 and the Jackery use it. For the Anker, we're checking.
What each box runs, and for how long
Take the box size in watt-hours. Keep 85% of it, because some power is lost inside the box. Then divide by the watts of the thing you plug in.
1,024 Wh × 0.85 ÷ 120 W = about 7.3 hours
That is a fridge on the DELTA 3. Our tools count 120 watts for a fridge. The table does the same math for six things.
| Thing | Watts | DELTA 3 or C1000 Gen 2 (about) | Explorer 1000 v2 (about) |
|---|---|---|---|
| Wi-Fi router | 15 W | 58 hours | 61 hours |
| Phones | 20 W | 44 hours | 45 hours |
| Lights | 40 W | 22 hours | 23 hours |
| TV | 100 W | 8.7 hours | 9.1 hours |
| Fridge | 120 W | 7.3 hours | 7.6 hours |
| Microwave | 1,100 W | 0.8 hours | 0.8 hours |
Estimates. Your devices may use more or less.
All three have enough output and surge for a fridge. Our tools count 1,200 watts of surge for a fridge. A 1,500-watt space heater is a different story. All three can send out 1,500 watts, but the Jackery has nothing left over, and any of these three empties in under an hour at that rate.
Charging
| Box | Wall charge, as the maker lists it | Maximum solar input |
|---|---|---|
| EcoFlow DELTA 3 | Full in 56 minutes (1,500 W input) | 500 W |
| Anker SOLIX C1000 Gen 2 | Full in 49 minutes with UltraFast (1,600 W), turned on in the Anker app. Standard wall input is 1,200 W at most. | 600 W |
| Jackery Explorer 1000 v2 | About 1.6 hours. About 1 hour in Emergency Super Charge, turned on in the Jackery app. | 400 W |
Solar time is at least the box size divided by the solar watts. That is at least 2.0 hours for the DELTA 3, 1.7 for the Anker, and 2.6 for the Jackery. Real sun gives fewer watts, so it takes longer. We're checking how many hours of strong sun to expect.
Which one fits you
- You may add more battery later: the DELTA 3 lists extra batteries up to 5 kWh total. Anker says the C1000 Gen 2 has no expansion feature.
- You want the most output of the three: the C1000 Gen 2 lists 2,000 watts.
- You carry the box often: the Jackery lists 23.8 pounds, the lowest of the three.
- You plug in many things: the DELTA 3 lists six AC outlets.
- You want the longest warranty: the DELTA 3 and the C1000 Gen 2 list 5 years, the Jackery lists 3.
Why this box? It lists 1,800 watts of output, 3,600 watts of surge, six AC outlets, a 5-year warranty, and room for extra batteries. The other two have strengths too, as the list shows. The BLUETTI Elite 100 V2 is also in this size, so check its sheet.

Questions people ask
Are these three the same size?
Almost. The DELTA 3 and the C1000 Gen 2 hold 1,024 watt-hours. The Jackery holds 1,070.
How long will they run a fridge?
About 7.3 hours for the first two and about 7.6 hours for the Jackery, by our math at 120 watts. Your fridge may use less on average, so you may get more, as our fridge guide explains.
Can I add more batteries later?
The DELTA 3 lists extra batteries, up to 5 kWh total. Anker says the C1000 Gen 2 has no expansion feature. For the Jackery, we're checking.
How long do they take to charge?
The Anker lists 49 minutes with UltraFast on, the DELTA 3 lists 56 minutes, and the Jackery lists about 1.6 hours, or about 1 hour in Emergency Super Charge. Check each row, because two of them need an app to turn on the quick mode.
