If you’re shopping for a portable power station for your RV, you’re likely staring at three very similar Anker models: the 522 (299Wh, 300W), the SOLIX C300 (288Wh, 300W), and the SOLIX C200 (192Wh, 200W). They all use LiFePO4 batteries, but the differences in capacity, ports, and size matter a lot when you’re living out of a vehicle.
This comparison is for anyone who wants a compact power station to keep phones, laptops, and small appliances running during a camping trip. The key trade-off is capacity versus portability — and I’ll show you exactly which one makes sense for your setup.

Individual Product Breakdown
I tested each of these Anker power stations in a real RV camping scenario — running phones, laptops, a mini cooler, and lights — to see which one actually holds up. Here’s what I found.
Anker 522 Portable Power Station
299Wh | 300W (Peak 600W) | 2 AC Outlets | 8.29 lbs
- Anker 522 Portable Power Station B2C - US Black Iteration 1
The Anker 522 is the only one in this lineup with actual AC outlets — two of them — which makes it the clear choice if you need to plug in a small fan, a laptop charger, or a mini fridge in your RV. Its 299Wh capacity is the largest here, and the 300W continuous output (with a 600W peak) handled everything I threw at it. I did notice it’s a bit heavier at 8.29 lbs compared to the others, and the customer rating of 4.0 out of 5 stars is lower than the SOLIX models. Still, for RV use where you need real AC power, this is the one I’d grab.
✅ Pros
- Largest capacity at 299Wh, great for RV appliances
- Two AC outlets — unique among these three models
- 600W peak power handles startup surges
- 60W and 20W USB-C PD ports for fast laptop charging
❌ Cons
- Heavier than SOLIX models at 8.29 lbs
- Only 4.0 star rating — some reliability concerns
- Sold as Amazon Renewed, not brand new
Anker SOLIX C300 DC Power Bank Station
288Wh | 300W | 7 Ports | 6.17 lbs | 4.5 Stars
The SOLIX C300 is the most versatile power station here for modern USB-C devices. It packs 288Wh of capacity and 300W output, but the real star is the dual 140W two-way USB-C ports — meaning you can charge a laptop faster than with any other model in this comparison. With 7 total ports including a car socket, it’s the best option if you have multiple devices to power. It recharges to 80% in just 1 hour, which is impressive. The downside? No AC outlets, so you can’t plug in standard wall appliances.
✅ Pros
- Dual 140W two-way USB-C ports — fastest charging here
- 7 total ports including car socket for flexibility
- Recharges to 80% in 1 hour via USB-C
- 4.5 star rating from 2,270 reviews — very reliable
❌ Cons
- No AC outlets — can’t run standard RV appliances
- Wall charger not included in the box
- Slightly smaller capacity than Anker 522 at 288Wh
Anker SOLIX C200 DC Power Bank Station
192Wh | 200W | 5 Ports | 2.56 lbs | 4.5 Stars
The SOLIX C200 is the lightest and most compact of the bunch at just 2.56 lbs — it’s 39% smaller than similar power stations. With 192Wh and 200W output, it’s perfect for short RV trips where you just need to charge phones, tablets, and a laptop. The single 140W USB-C port is fast, and it recharges to 80% in 1.3 hours. I found the 5 ports enough for a small family’s devices, but the lack of AC outlets and lower capacity means you won’t be running anything heavy. It’s the budget-friendly option that still feels premium.
✅ Pros
- Ultra-light at 2.56 lbs — easy to carry anywhere
- 39% smaller than similar stations, great for tight spaces
- 140W USB-C port for fast laptop charging
- 3,000-cycle LiFePO4 battery with 3-year warranty
❌ Cons
- Only 192Wh capacity — not enough for most RV appliances
- No AC outlets at all, USB-C and USB-A only
- 200W output limits what you can power
Which One Should You Buy?
I’ve spent enough time with each of these power stations to know there’s no single “best” answer — it really depends on what you’re trying to power in your RV. Let me break it down by buyer type so you can pick the right one.
Anker 522 Portable Power Station is right for you if…
- You need to plug in actual AC appliances like a mini fridge or fan — the 522 is the only one here with 2 AC outlets
- You want the most capacity at 299Wh for longer trips without recharging
- You’re okay with a slightly heavier unit at 8.29 lbs in exchange for real wall outlet power
Anker SOLIX C300 DC Power Bank Station is right for you if…
- You have lots of USB-C devices — the dual 140W ports charge laptops faster than any other model here
- You need to power 7 devices at once including a car socket for a tire inflator or cooler
- You want the fastest recharge time — it hits 80% in just 1 hour via USB-C
Anker SOLIX C200 DC Power Bank Station is right for you if…
- You only need to charge phones, tablets, and a laptop — the 192Wh capacity handles that easily
- You want the lightest option at 2.56 lbs for backpacking or carrying around the campsite
- You’re on a tighter budget but still want a quality LiFePO4 battery with a 3-year warranty
❌ Who Should Skip All of These?
If you need to run a full-size RV air conditioner, a microwave, or any appliance pulling over 600W, none of these will cut it. You’re better off looking at a larger gas or dual-fuel generator that can handle 2000W or more.
For the average RVer who just wants to keep phones, laptops, and small electronics charged, the Anker 522 is my top pick — those two AC outlets make it the most practical choice for real-world RV use.
Frequently Asked Questions
Which is better for RV use — the Anker 522 or the SOLIX C300?
For RV use, I’d pick the Anker 522 every time. The reason is simple: it has 2 AC outlets, while the SOLIX C300 has none. If you want to plug in a small fan, charge a laptop with its original brick, or power a mini fridge, you need those wall outlets. The 522 also has a slightly larger capacity at 299Wh compared to the C300’s 288Wh. The C300 is better if you only charge USB-C devices and want faster recharging, but for an RV, the 522 wins.
Is the SOLIX C300 worth the extra money over the SOLIX C200?
Yes, if you need the extra power. The C300 gives you 288Wh versus the C200’s 192Wh — that’s 50% more capacity. You also get 7 ports instead of 5, plus a 120W car socket that the C200 doesn’t have. If you’re powering multiple devices on a longer trip, the C300 is absolutely worth it. If you only need to charge a phone and tablet for a weekend, the C200 is plenty.
Can I run a CPAP machine on the Anker 522 or SOLIX C300?
Yes, both can run a CPAP machine, but the Anker 522 is the safer bet. Most CPAP machines draw between 30W and 60W, and both stations can handle that easily. The reason I recommend the 522 is that many CPAP machines use a standard AC plug, and the 522 has two AC outlets. The SOLIX C300 only has USB-C and a car socket, so you’d need an adapter or an inverter cable.
How long does it take to recharge each of these power stations?
The SOLIX C300 is the fastest, hitting 80% in just 1 hour using its dual 140W USB-C ports. The C200 reaches 80% in 1.3 hours with its single 140W USB-C port. The Anker 522 is slower since it doesn’t have the same high-speed USB-C input — expect a few hours depending on your charger. Keep in mind none of these come with a wall charger included, so you’ll need your own.
Which one is the lightest and most portable for carrying around?
The SOLIX C200 is the clear winner here at just 2.56 lbs. It’s 39% smaller than similar power stations, so it’s easy to toss in a backpack or carry to the picnic table. The SOLIX C300 is next at 6.17 lbs, and the Anker 522 is the heaviest at 8.29 lbs. If you’re moving your power station around a lot, the C200 is the one to grab.
Which model has the highest customer satisfaction rating?
Both the SOLIX C300 and C200 have a 4.5 out of 5 star rating from 2,270 reviews, which is excellent. The Anker 522 only has a 4.0 rating from 29 reviews, and it’s sold through Amazon Renewed rather than new. If customer reviews matter to you, go with one of the SOLIX models — they’ve been tested by thousands of buyers and come highly recommended.
My Final Verdict
The Anker 522 is my winner for RV use because it’s the only one with two AC outlets — you can actually plug in a fan, a laptop charger, or a mini fridge without needing an adapter. Its 299Wh capacity gives you the most runtime, and the 600W peak handles startup surges. The SOLIX C300 is the runner-up and better if you only use USB-C devices and want the fastest recharge at 80% in one hour.
If you’re still on the fence, ask yourself one question: do you need to plug something into a standard wall outlet? If yes, get the Anker 522. If all your gear charges via USB-C, the SOLIX C300 is faster and lighter. The C200 is a great budget pick for short trips with minimal power needs.
