Our verdict · Anker SOLIX
The fastest-charging 1 kWh station, with class-leading output
Refills from the wall in under an hour, runs most single household appliances at 2,000 W and switches over in 10 ms. The catch: 1,024 Wh is all you'll ever get, because it takes no extra batteries.
- Capacity
- 1,024 Wh
- AC output
- 2,000 W
- Wall charge
- 49 min
- Weight

Best for
Essentials backup, home offices and car camping where fast recharging and 2,000 W of output matter more than room to grow.
Skip it if
You want to add batteries later, need more than about 1 kWh, or plan to charge it fast in a cold garage.
- Full wall charge in 49 minutes (UltraFast)
- 2,000 W continuous, 3,000 W peak
- 10 ms UPS switchover
- Two 140 W USB-C ports
- 24.9 lb for 1,024 Wh
- Not expandable
- UltraFast needs the battery above 68 °F

Key specs at a glance
What the numbers mean in practice
- 1,024 Wh capacity: a mid-size battery. Enough to keep a fridge and router going for most of a night, or a CPAP for several nights on DC.
- 2,000 W continuous, 3,000 W peak: runs most single kitchen appliances (coffee maker, microwave, kettle, hair dryer), but not several at once.
- LiFePO4, 4,000 cycles to 80%: the long-life chemistry. See LiFePO4 vs lithium-ion.
- 24.9 lb: one of the lightest stations in its class; easy to carry with one hand.
- Not expandable: 1,024 Wh is all you'll get.
- 5-year warranty.

Charging speed
Its standout feature
In UltraFast mode the C1000 Gen 2 takes 1,600 W from the wall for a full charge in about 49 minutes, among the fastest in its class. Standard AC charging is 1,200 W. UltraFast is switched on in the Anker app and only works when the battery is above 68 °F, so in a cold garage it falls back to slower charging.
It also accepts up to 600 W of solar through one input (11–60 V), filling the battery in about 1.8 hours in strong sun with enough panels, and 120 W from a car socket.
Capacity and real runtime
How long it actually keeps things running
Estimated runtimes on the C1000 Gen 2
- CPAP, no humidifier, DC cord27 h
- CPAP with humidifier, AC11 h
- Fridge + Wi-Fi router11 h
A fridge and router running through the night is realistic; a full day of fridge backup needs some solar, since there is no add-on battery. Try your own devices in the runtime calculator.
Output: what it can and can't run
Strong for one appliance at a time
The 2,000 W continuous rating covers most single household appliances across its 5 AC outlets, and the 3,000 W peak helps start a fridge or small pump. Two 140 W USB-C ports charge laptops at full speed at the same time, alongside one USB-A port and a 12 V car socket.
What it won't do well: run a microwave and a kettle together, power a space heater for long, or start larger motors like well pumps. Its 2,000 W is more than the 1,800 W of the EcoFlow Delta 3 Plus.
Backup (UPS) and app
Fast switchover for computers and routers
The C1000 Gen 2 switches to battery in 10 ms when the grid drops, fast enough for most computers, routers and networking gear to keep running (see using a power station as a UPS). The Anker app (Wi-Fi and Bluetooth) shows input and output, sets schedules and has a Time-of-Use mode that charges when electricity is cheap and runs your devices from the battery when rates peak.
How it compares
Against similar 1 kWh stations
| Spec | Anker SOLIX C1000 Gen 2 | EcoFlow Delta 3 Plus | Bluetti AC180 |
|---|---|---|---|
| Capacity (Wh) | 1024 | 1024 | 1152 |
| AC output, continuous (W) | 2000 | 1800 | 1800 |
| AC charge time | 49 min (UltraFast) | 56 min | 80% in 45 min |
| Max solar input (W) | 600 | 1000 | 500 |
| Weight (lb) | 24.9 | 27.6 | 35.3 |
| Warranty (years) | 5 | 5 | 5 |
| Price | Check price | Check price | Check price |
- EcoFlow Delta 3 Plus: same capacity and a similar charge time, more solar input (1,000 W) and expandable to 5 kWh, but 1,800 W output.
- Bluetti AC180: a little more capacity (1,152 Wh), 1,800 W output, slower solar (500 W) and heavier (35.3 lb).
The C1000 Gen 2's edge is output and weight. The Delta 3 Plus wins if you might add capacity later. See the full Delta 3 Plus vs C1000 Gen 2 comparison. For the brands overall, see Anker SOLIX vs EcoFlow.
Who should buy it
And who should look elsewhere
Good fit: essentials backup (fridge, router, lights, CPAP); a home office that needs a reliable UPS; car camping; anyone who wants the most output and the fastest recharge in a 1 kWh station they can carry.
Look elsewhere if: you want to add capacity later (the Delta 3 Plus expands to 5 kWh), or you need whole-home backup (consider the Anker SOLIX F3800 Plus). For battery chemistry trade-offs, see LiFePO4 vs lithium-ion.

FAQ
Quick answers to common questions
How long will the C1000 Gen 2 run a refrigerator?
About 10–11 hours for a typical fridge plus a router, or a little longer for the fridge alone. Real results depend on your fridge's average draw.
How long does the C1000 Gen 2 take to charge?
About 49 minutes from empty to full in UltraFast mode (1,600 W), when the battery is above 68 °F. Standard AC charging runs at 1,200 W.
Can the C1000 Gen 2 be used as a UPS?
Yes. It switches over in 10 ms, fast enough for most computers and routers.
Is the C1000 Gen 2 expandable?
No. It has no expansion battery port, so 1,024 Wh is its full capacity.
Is it LiFePO4?
Yes. It uses LiFePO4 (LFP) cells rated for 4,000 cycles to 80% capacity.
What warranty does it have?
Five years.
