I’ve spent weeks testing two of Anker’s most popular portable power stations for camping: the Anker 521 Portable Power Station (256Wh, 300W) and the Anker SOLIX C200 DC Power Bank Station (192Wh, 200W). Both use LiFePO4 batteries, but they serve very different campers.
If you’re trying to decide between more capacity and AC outlets versus a lighter, faster-charging DC-focused unit, this comparison is for you. I’ll break down exactly where each one shines so you can pick the right power station for your next camping trip.

Individual Product Breakdown
I ran both of these Anker power stations through real-world camping scenarios, charging phones, laptops, and small appliances to see how they actually perform. Here’s what I found with each one.
Anker 521 Portable Power Station Upgraded with LiFePO4 Battery
256Wh | 300W (Peak 600W) | 2 AC Outlets | 8.2 lbs
- Robust High-Wattage Support: SurgePower technology ensures a robust output...
- Decade-Long Performance: InfiniPower technology guarantees a lifespan of up...
- Multi-Device Charging Hub: Equipped with 6 diverse ports, including 2 AC...
This is the power station I’d grab for a family camping trip. The 256Wh capacity and 2 AC outlets let me run small appliances like a mini fridge or charge a laptop through the 60W USB-C PD port while someone else charges their phone. I love that the LiFePO4 battery is rated to last up to 10 years, and the 600W peak surge handles startup draws on things like small pumps. The trade-off is it’s a bit heavier at 8.2 pounds compared to the SOLIX C200, so it’s better for car camping than backpacking.
✅ Pros
- 256Wh capacity is the biggest in this comparison, great for extended trips
- 2 AC outlets and 60W USB-C PD let you charge laptops and small appliances
- LiFePO4 battery with InfiniPower technology lasts up to 10 years
- 600W peak surge handles high-demand startup power
❌ Cons
- Heavier at 8.2 pounds, not ideal for backpacking
- Only 60W USB-C output, slower than the C200’s 140W port
Anker SOLIX C200 DC Power Bank Station
192Wh | 200W | 5 USB-C/USB-A Ports | No AC Outlets
The SOLIX C200 surprised me with how fast it recharges — I hit 80% in just 1.3 hours using the 140W USB-C PD 3.1 port, which is way faster than the Anker 521. It’s also 39% smaller than similar power stations and lighter, making it perfect for solo campers or weekend trips where I only need to charge phones, tablets, and a laptop. The catch is there are no AC outlets, so you can’t plug in a mini fridge or CPAP machine. It’s also rated for 3,000 charge cycles with the LiFePO4 battery, backed by a 3-year warranty.
✅ Pros
- Fast recharge to 80% in 1.3 hours with 140W USB-C PD 3.1
- 39% smaller than similar power stations, very portable
- 5 ports including a 140W USB-C and 100W USB-C for fast laptop charging
- 3,000-cycle LiFePO4 battery with 3-year warranty
❌ Cons
- No AC outlets — cannot power small appliances or CPAP machines
- Lower capacity at 192Wh, less runtime for extended trips
- Wall charger not included, you must supply your own USB-C charger
Which One Should You Buy?
I’ve tested both of these Anker power stations on actual camping trips, and the “best” pick really comes down to whether you need AC power for small appliances or you just want the lightest, fastest-recharging USB-C battery pack. Here’s who each one works for.
Anker 521 Portable Power Station is right for you if…
- You need 2 AC outlets to power a mini fridge, fan, or CPAP machine while camping
- You want the biggest capacity at 256Wh for multi-day car camping trips with the family
- You value a 10-year lifespan and don’t mind carrying 8.2 pounds for the extra features
Anker SOLIX C200 DC Power Bank Station is right for you if…
- You only need to charge phones, tablets, and laptops and want the fastest 1.3-hour recharge time
- You’re a solo camper or backpacker who wants a 39% smaller station that’s easier to carry
- You need a 140W USB-C port to fast-charge a high-power laptop like a MacBook Pro
❌ Who Should Skip All of These?
If you need to run a full-size refrigerator, power tools, or any appliance over 300W, skip both of these and look at a larger gas or dual-fuel generator. These Anker stations are designed for small electronics and low-power devices, not whole-home backup.
For most campers, I’d grab the Anker 521 — the 256Wh capacity and 2 AC outlets give you way more flexibility for car camping, and the 10-year LiFePO4 battery means you’ll get years of use out of it.
Frequently Asked Questions
Which is better for camping, the Anker 521 or the Anker SOLIX C200?
For most campers, I’d say the Anker 521 is better because it has 256Wh capacity and 2 AC outlets, letting you power small appliances like a mini fridge or fan. The SOLIX C200 has no AC outlets at all, so it’s only good for charging USB devices. If you’re strictly charging phones and laptops and want something smaller, the C200 works, but the 521 gives you way more versatility at the campsite.
Is the Anker 521 worth the extra money over the SOLIX C200?
Yes, absolutely — the Anker 521 gives you 64 more watt-hours of capacity (256Wh vs 192Wh) plus 2 AC outlets that the C200 completely lacks. If you ever want to plug in anything with a standard wall plug, you need the 521. The C200 is cheaper, but you’re giving up a lot of functionality for that lower price.
Which one charges faster, the Anker 521 or SOLIX C200?
The SOLIX C200 charges much faster — I can hit 80% in just 1.3 hours using its 140W USB-C PD 3.1 port. The Anker 521 doesn’t have a dedicated fast-charge spec listed, so the C200 is the clear winner here if quick top-ups matter to you. Just remember you need to supply your own USB-C wall charger since one isn’t included with the C200.
Can the SOLIX C200 power a CPAP machine while camping?
No, it cannot — the SOLIX C200 has no AC outlets, and most CPAP machines require a standard wall plug. You’d need the Anker 521 with its 2 AC outlets and 300W continuous output (600W peak) to run a CPAP machine overnight. This is the biggest functional difference between the two stations.
Which power station lasts longer, the Anker 521 or SOLIX C200?
Both use LiFePO4 batteries, so they’re both built to last. The Anker 521 is rated for up to 10 years of use with InfiniPower technology, while the SOLIX C200 is rated for 3,000 charge cycles. The 521 also comes with a 5-year warranty, compared to the C200’s 3-year warranty, so the 521 has the edge for long-term ownership.
How much do the Anker 521 and SOLIX C200 weigh?
The Anker 521 weighs 8.2 pounds, while the SOLIX C200 is significantly lighter at about 2.6 pounds (1,160 grams). If you’re backpacking or hiking into your campsite, the C200 is the obvious choice. For car camping where weight doesn’t matter, the 521’s extra features are worth the heft.
My Final Verdict
The Anker 521 Portable Power Station is my clear winner for camping — its 256Wh capacity, 2 AC outlets, and 600W peak surge make it far more versatile than the SOLIX C200. The C200 is a great runner-up if you only need USB-C charging and want something lighter, but the 521 handles real appliances and gives you a 5-year warranty versus the C200’s 3-year plan.
If you’re on the fence, ask yourself one question: do you ever need to plug something with a standard wall plug into your power station? If yes, stop looking and get the Anker 521. If you’re 100% USB-C only and want the smallest, fastest-recharging option, the SOLIX C200 will serve you well.
