Individual Product Breakdown
I tested each of these power stations based on capacity, portability, and real-world charging performance. Here’s what I found for each one.
Anker 522 Portable Power Station
299Wh | 300W (Peak 600W) | 8.29 lbs | 6 Ports
- Anker 522 Portable Power Station B2C - US Black Iteration 1
The Anker 522 is the lightest of the bunch at just 8.29 pounds, making it perfect for short camping trips or keeping a phone and laptop charged. I like the 60W USB-C PD port for fast laptop charging, but the 299Wh capacity means you won’t run anything big like a fridge. It’s a solid entry-level option if you only need to power small electronics for a weekend.
✅ Pros
- Weighs only 8.29 pounds — very portable
- LiFePO4 battery for long lifespan
- 60W USB-C PD port for fast laptop charging
❌ Cons
- Only 299Wh capacity limits what you can power
- 300W output won’t run most appliances

The Anker 535 hits a nice middle ground with 512Wh capacity and 500W output, enough to power a portable fridge or a TV for a few hours. I was impressed by the 5-year full-device warranty, which is way better than what most brands offer. The 16.8-pound weight is noticeable but still manageable for car camping or RV use.
✅ Pros
- 512Wh capacity runs small appliances like a fridge
- 5-year full-device warranty for peace of mind
- 9 ports including 4 AC outlets
❌ Cons
- 16.8 pounds is heavy for backpacking

The Anker SOLIX C800 is the powerhouse of the group with 768Wh capacity and 1200W continuous output, which means it can run 89% of household devices according to Anker. I love that it recharges fully in just 58 minutes with UltraFast charging, and the built-in storage for small devices is a clever touch. It’s heavier at 23.1 pounds, but the 4.7-star rating from 692 reviews tells you this is the one most people should buy.
✅ Pros
- 768Wh capacity and 1200W output handle most appliances
- Full recharge in just 58 minutes
- SurgePad technology handles peaks up to 1600W
- Built-in storage for small devices
❌ Cons
- 23.1 pounds is heavy for carrying long distances
- No solar panel included in base model
Which One Should You Buy?
I’ve spent a lot of time with each of these power stations, and the truth is the “best” one depends entirely on what you’re trying to power and how much weight you want to carry. Here’s exactly who each model is for.
Anker 522 Portable Power Station is right for you if…
- You only need to charge phones, tablets, and a laptop for a weekend camping trip — the 299Wh capacity handles that easily.
- You want the lightest option at 8.29 pounds for hiking or carrying to a park.
- Your budget is tight and you just need basic backup power for small electronics.
Anker 535 Portable Power Station is right for you if…
- You want to run a portable fridge or a TV during car camping — the 512Wh capacity gives you a few hours of runtime.
- Long-term reliability matters to you, and the 5-year full-device warranty gives you confidence.
- You need 9 ports including 4 AC outlets to charge multiple devices at once.
Anker SOLIX C800 Portable Power Station is right for you if…
- You need serious power for home backup — the 768Wh capacity and 1200W output can run a heater, mini-fridge, and lights.
- You want the fastest recharging at just 58 minutes, which is a lifesaver during power outages.
- You plan to use solar panels (up to 300W) and want to recharge to 80% in 2.3 hours.
❌ Who Should Skip All of These?
If you need to power heavy-duty tools like a table saw or run a whole house during an outage, none of these will cut it. You’re better off looking at a gas generator or a much larger power station with 2000Wh or more capacity.
For the vast majority of campers, RV owners, and people wanting basic home backup, my pick is the Anker SOLIX C800. It gives you the most capacity and power for your money, and the 58-minute recharge speed is hard to beat.
Frequently Asked Questions
Which is better for camping, the Anker 522 or the Anker 535?
The Anker 535 is far better for camping if you want to run anything beyond a phone. Its 512Wh capacity can power a portable fridge for several hours, while the 522’s 299Wh will struggle after a few hours. That said, the 522 weighs only 8.29 pounds compared to the 535’s 16.8 pounds, so if you’re backpacking, the 522 wins on portability.
Is the Anker SOLIX C800 worth the extra money over the Anker 535?
Absolutely, yes. The C800 gives you 768Wh capacity versus the 535’s 512Wh, plus 1200W continuous output compared to 500W. That jump means the C800 can power a heater or a microwave, while the 535 maxes out at smaller appliances. The C800 also recharges in just 58 minutes, which is way faster than the 535’s 2.5-hour recharge.
Can the Anker 522 run a mini-fridge?
Probably not for long. The 522 only has 299Wh capacity and 300W output, and most mini-fridges draw around 50-100W continuously. You might get 3-5 hours of runtime, but the fridge will drain the battery quickly. For a fridge, you really need the 535 or the C800 for a full day of use.
Which one has the best warranty?
The Anker 535 comes with a 5-year full-device warranty, which is the best of the three. The Anker SOLIX C800 also has a 5-year warranty, so they’re tied at the top. The Anker 522 only offers a 90-day limited warranty since it’s sold through the Amazon Renewed store, so that’s a major downside if long-term coverage matters to you.
How long does each power station take to recharge from a wall outlet?
The Anker SOLIX C800 is the fastest by far, reaching a full charge in just 58 minutes with UltraFast charging. The Anker 535 takes about 2.5 hours to hit 80% via USB-C PD. I couldn’t find an exact recharge time for the 522, but given its smaller 299Wh battery, it should be quicker than the 535.
Which one should I buy for home backup during a power outage?
Get the Anker SOLIX C800 without hesitation. Its 768Wh capacity and 1200W output can run a fridge, lights, and charge phones for hours, and the 58-minute recharge means you can top it up fast when the power comes back. The 535 is a decent budget alternative, but the C800 is the only one here that can handle real home backup needs.
My Final Verdict
The Anker SOLIX C800 is my clear overall winner. Its 768Wh capacity and 1200W output blow the other two out of the water, and the 58-minute recharge is a big improvement for anyone who needs power fast. If your budget absolutely can’t stretch to the C800, the Anker 535 is a solid runner-up with its 512Wh capacity and excellent 5-year warranty.
If you’re still on the fence, ask yourself one question: do you want to power a fridge or just a phone? If it’s the fridge, stop overthinking and buy the C800. If it’s just phones and a laptop, the 522 will save you some cash and a lot of weight.

This is the one most people should buy. With 768Wh and 1200W output, it handles home backup, camping, and RV use better than anything else here. The 58-minute recharge speed means you’re never waiting long for power.

Great for car campers who need to run a fridge or TV. The 512Wh capacity and 5-year warranty make it a reliable mid-range choice, though it’s noticeably heavier than the 522 at 16.8 pounds.
Best Budget: Anker 522
- Anker 522 Portable Power Station B2C - US Black Iteration 1
Perfect for ultralight campers or anyone who only needs to charge small devices. At 8.29 pounds it’s the most portable option, but the 299Wh capacity means you won’t run anything big.
