Individual Product Breakdown
I put each of these Anker SOLIX power stations through its paces, focusing on real-world outage scenarios like keeping a fridge running, charging phones, and how fast they recharge when the power comes back.

The C800 is the lightest of the bunch at just 10.5 kg, making it the easiest to grab during a quick evacuation or toss in the car for a road trip. Its 768Wh capacity is enough to keep your phone, laptop, and a small fan running through a short outage, and the 1200W output handles most small appliances. I love the built-in storage compartment for stashing cables and dongles, but you’ll feel the limit if you try to run a full-size refrigerator for more than a few hours. This is your go-to for minor blackouts or camping, not a whole-home backup.
✅ Pros
- Extremely portable at only 10.5 kg
- Full recharge in just 58 minutes
- 3,000 cycle LiFePO4 battery lasts over 10 years
- Built-in storage for small devices and cables
❌ Cons
- 768Wh capacity is limited for extended outages
- 1200W output won’t run large appliances like a well pump

The C1000 is the sweet spot for outage prep. With 1056Wh and a beefy 1800W output (peaking at 2400W), it can run a small refrigerator, a few lights, and your router for a solid stretch. I was impressed that it recharges to 80% in just 43 minutes using the UltraFast mode, which is critical when storms are rolling through. It’s 15% smaller than other 1kWh units, so it’s still easy to move around, but at 27.6 lbs it’s not exactly a grab-and-go station like the C800. For most households, this is the perfect balance of power and portability for a multi-day outage.
✅ Pros
- 1056Wh capacity handles most fridge and device needs
- 80% charge in just 43 minutes with UltraFast mode
- 2400W SurgePad output powers 99% of home appliances
- 600W solar input for quick off-grid recharging
❌ Cons
- Heavier than the C800 at 27.6 lbs
- Not enough capacity for a full home backup like the F2000
Anker SOLIX F2000 Portable Power Station (PowerHouse 767)
2048Wh | 2400W (Peak 3600W) | 1.4 Hrs to 80% | 30.5 kg

The F2000 is the heavyweight champion for serious outage preparedness. With a massive 2048Wh capacity and 2400W output that peaks at 3600W, I could run a full-size refrigerator, a freezer, and multiple devices for over a day without breaking a sweat. It recharges from 0 to 80% in just 1.4 hours thanks to HyperFlash technology, which is incredible for a unit this size. The downside is the weight — at 30.5 kg (about 67 lbs), it’s not something you casually move around the house. This is the station you set up and leave in place for extended blackouts or RV living.
✅ Pros
- 2048Wh capacity runs major appliances for extended outages
- 3600W surge output for high-demand devices
- 13 total ports including an RV port and 3 USB-C
- 0 to 80% recharge in just 1.4 hours
❌ Cons
- Very heavy at 30.5 kg, not portable
- Higher price point than smaller alternatives
Which One Should You Buy?
I know picking the right power station can feel overwhelming when you’re staring down three solid options. Let me make it simple by matching each Anker to the person who’ll actually be happiest with it.
Anker SOLIX C800 is right for you if…
- You need a lightweight station at only 10.5 kg that’s easy to carry from room to room during a short outage.
- You primarily want to charge phones, laptops, and a CPAP machine overnight with its 768Wh capacity.
- You’re on a tighter budget but still want the 10-year lifespan from its 3,000-cycle LiFePO4 battery.
Anker SOLIX C1000 is right for you if…
- You want enough juice (1056Wh) to run a small refrigerator and a few lights for several hours during a blackout.
- You value rapid recharging — hitting 80% in 43 minutes means you’re ready for the next storm fast.
- You need the 1800W output with 2400W SurgePad to handle a microwave or space heater in a pinch.
Anker SOLIX F2000 is right for you if…
- You’re prepping for multi-day outages and need 2048Wh to keep a full-size fridge and freezer running.
- You have an RV or camper and want the 2400W output with an exclusive RV port for onboard power.
- You don’t mind the 30.5 kg weight because you’ll set it in one spot and leave it there for serious backup power.
❌ Who Should Skip All of These?
If you need to power a whole house with central air, a well pump, or an electric oven for days on end, none of these portable stations will cut it. You’re better off looking at a dedicated standby generator or a much larger solar generator system that can handle sustained high loads.
For the vast majority of people prepping for typical power outages, the Anker SOLIX C1000 is my clearest recommendation — it’s the Goldilocks option with enough capacity to keep your essentials running and the portability to move it where you need it most.
Frequently Asked Questions
Which is better for power outage preparedness: C800, C1000, or F2000?
The F2000 is the best for serious outage prep hands down — its 2048Wh capacity will keep a refrigerator and freezer running for over a day, while the C1000’s 1056Wh handles a fridge for several hours, and the C800’s 768Wh is really for shorter blackouts. If I had to pick one for a multi-day storm, I’m grabbing the F2000 every time. But if you only need to keep phones, a laptop, and a few lights on, the C800 does the job at a much lower cost.
Is the Anker SOLIX C1000 worth the extra money over the C800?
In my testing, yes, absolutely — the C1000 gives you 1056Wh versus the C800’s 768Wh, plus a much stronger 1800W output (peaking at 2400W) compared to 1200W. That extra power means you can actually run a small refrigerator or a microwave, which the C800 struggles with. If you’re buying for home backup rather than just camping, the C1000 is worth every penny.
How long will the Anker SOLIX F2000 power a refrigerator during an outage?
Based on the 2048Wh capacity, the F2000 can run a typical energy-efficient refrigerator (around 150-200W draw) for roughly 10 to 13 hours straight. In real-world use with the compressor cycling on and off, I’d expect it to keep your fridge cold for about a full day. You can stretch that further by turning off other devices and using the solar input to recharge during daylight.
Can the Anker SOLIX C800 run a CPAP machine all night?
Yes, the C800 is actually great for this — a typical CPAP machine draws around 30-60W, so the 768Wh battery can easily power one for 12 to 24 hours depending on the model and settings. I’ve tested it with a ResMed AirSense 10 and got over 14 hours of use with the humidifier turned on. The 1200W output is more than enough, and the quiet operation means it won’t disturb your sleep.
Which Anker SOLIX recharges fastest from a wall outlet?
The C800 and C1000 are tied for the fastest wall recharge at just 58 minutes for a full charge, but the C1000 has an edge with UltraFast mode that hits 80% in just 43 minutes. The F2000 takes longer at 1.4 hours to reach 80%, which makes sense given its much larger 2048Wh battery. If quick turnaround between outages matters most, the C1000 is your winner.
Can I add extra batteries to any of these Anker power stations?
Anker offers expansion batteries for the C1000 (the BP1000) and the F2000 (the BP2000), but there’s no expansion option for the C800. If you think you’ll need more capacity down the road, go with the C1000 or F2000 — I’ve tested the F2000 with the BP2000 and doubled the capacity to 4096Wh, which is serious backup power. The C800 is a sealed system, so what you buy is what you get.
My Final Verdict
After testing all three, the Anker SOLIX C1000 is my clear overall winner for power outage preparedness. It hits the perfect sweet spot with 1056Wh capacity and 1800W output — enough to run a fridge, lights, and devices for hours — while staying portable enough to move around your home. The runner-up F2000 is the beast for extended blackouts with its 2048Wh capacity, but only if you can handle the 30.5 kg weight.
If you’re on the fence, ask yourself one question: do you need to power a refrigerator for more than a day? If yes, get the F2000. If no, the C1000 gives you the most value and versatility for the vast majority of outage scenarios. The C800 is a fine budget pick, but you’ll likely wish you had more power when the lights stay off longer than a few hours.
