Verdict: the Anker SOLIX C1000 Gen 2 packs more power into a compact 1 kWh box than almost anything else in its class. It delivers 2,000 W from five AC outlets (3,000 W peak), recharges from empty in about 49 minutes with HyperFlash, switches to battery in 10 ms, stays around 20 dB under light loads and weighs 24.9 lb. It’s an outstanding all-rounder for home backup, CPAP and camping. Its trade-offs: it can’t be expanded, and it accepts less solar than the EcoFlow DELTA 3 Plus or BLUETTI Elite 100 V2.
| Best for | Home backup with bigger appliances, CPAP users, anyone who wants the fastest recharge |
| Not ideal for | Buyers who may need more capacity later; heavy solar users |
| Key numbers | 1,024 Wh · 2,000 W (3,000 W peak) · 10 ports · ~49-min recharge · 10 ms UPS · 24.9 lb |

All 10 ports, and what to plug into each
| Port | Best used for |
|---|---|
| 5 × AC outlets (2,000 W total) | Refrigerator, microwave or kettle in short bursts, TV, fans, lamps, CPAP power brick |
| 2 × USB-C 140 W | Laptops, including power-hungry models; tablets; more efficient than the AC outlet |

| 1 × USB-A 12 W | Older phones, headlamps, gadgets |
| 1 × 12 V car socket (120 W) | 12 V compressor coolers, water pumps and your CPAP maker’s DC converter |
Charging: HyperFlash, solar and car
| Method | Max input | Time to full (from empty) |
|---|---|---|
| Wall, UltraFast (HyperFlash) mode | 1,600 W | About 49 minutes |
| Wall, standard mode | 1,200 W | Around an hour or a little more (our estimate) |
| Solar panels | 600 W (11–60 V) | About 1.8 hours in ideal sun; typically 2–3 hours in real conditions |
| Car socket | Low | Many hours; best for topping up while driving |
The 49-minute recharge is the C1000 Gen 2’s signature feature: when a storm is forecast, even a short window of grid power is enough to fill it. For long outages where solar is your main source, its 600 W input is solid but not class-leading. See how to charge a power station with solar.
What it can run, and for how long
| Device | Typical draw | Estimated runtime |
|---|---|---|
| Average full-size refrigerator | 1.5 kWh/day (~62 W average) | ~12 hours |
| Efficient ENERGY STAR refrigerator | 1.0 kWh/day (~42 W average) | ~16 hours |
| CPAP, humidifier off | ~30 W | ~2.7 nights |
| CPAP, humidifier on | ~55 W | ~1.7 nights |
| Wi-Fi router and modem | ~15 W | ~35 hours |
| Laptop (via AC) | ~50 W | ~14–15 hours |
| Box fan | ~50 W | ~14–15 hours |
| 50-inch LED TV | ~100 W | ~8 hours |
| Microwave | ~1,000 W | ~50 minutes of total cooking time |
| Space heater on high | ~1,500 W | ~35 minutes |
Three real-world scenarios
1. A storm is coming
Your battery sits at 30%. With HyperFlash on, less than an hour on the wall gets you to full. During the outage, a refrigerator, Wi-Fi, a lamp and phones (roughly 90–100 W together) run for about 9 hours.
2. Cooking during an outage
With 2,000 W of output, it can run a typical microwave or electric kettle while the fridge keeps going. Keep these high-watt uses short: 10 minutes of microwave use (about 170 Wh) costs roughly as much energy as two and a half to three hours of refrigerator time.
3. CPAP in the bedroom
Plugged into the wall with your CPAP plugged into it, the C1000 Gen 2 takes over within 10 ms if the power fails at 3 a.m. At CPAP-level loads it’s rated around 20 dB, quieter than a whisper. It’s our top pick in best power stations for CPAP.

Frequently asked questions
Does it really recharge in 49 minutes?
That’s Anker’s figure with UltraFast (HyperFlash) mode enabled in the app, drawing up to 1,600 W from a standard outlet. In standard mode it charges at up to 1,200 W, which takes longer.
Can it run a refrigerator?
Yes. Its 2,000 W output and 3,000 W peak easily handle a refrigerator’s startup, and it runs an average one for about 12 hours.
Can I add an extra battery?
No. Anker made the Gen 2 fixed-capacity to keep it smaller and lighter. If expansion matters, look at the EcoFlow DELTA 3 Plus, which grows to 5 kWh.
Can I use it while it charges?
Yes. In bypass mode it passes up to 1,800 W from the wall to your devices while charging, and switches to battery in 10 ms if the grid fails.
Can I charge it in the cold?
Only above 32°F (0°C). It can supply power down to −4°F, but keep it indoors in winter and charge it at room temperature.
The bottom line
If you want the most output and the fastest recharge in a compact 1 kWh box, the Anker SOLIX C1000 Gen 2 is our pick. Choose the EcoFlow DELTA 3 Plus instead if you want to expand later or rely heavily on solar.
