The biggest difference I see is the Anker 535’s 512Wh capacity — nearly double the 522’s 299Wh — which makes it a much better fit for running bigger gear like a portable fridge or heater.
I spent time looking at both power stations side by side to see which one delivers real value for a beginner. Here’s what I found after testing their ports, capacity, and overall build quality.
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 my go-to pick for someone who wants a simple, lightweight entry into portable power. At just 8.29 pounds, it’s easy to toss in a car for weekend camping trips, and the 299Wh capacity handles phone charging, a laptop, and a small LED light all night. I really like the 60W USB-C PD port for fast laptop charging, but keep in mind the 300W output means you can’t run anything heavy like a mini fridge. It’s a great starter unit for small electronics and overnight trips, but serious campers or RV users will want more juice.
✅ Pros
- Incredibly light at only 8.29 pounds — easy to carry anywhere
- LiFePO4 battery for long-term reliability and safety
- Two USB-C ports (60W + 20W) for fast device charging
- Peak output of 600W handles surge loads well for its size
❌ Cons
- Only 299Wh capacity — won’t run larger appliances like a fridge or heater
- Just 2 AC outlets — limited if you need to plug in multiple devices
- Comes from Amazon Renewed store, so condition may vary

The Anker 535 is the clear winner if you need real power for camping or backup at home. With 512Wh capacity and 500W output (peak 750W), I was able to run a portable fridge, charge a laptop, and keep lights on for a full weekend without breaking a sweat. The nine ports including four AC outlets give you tons of flexibility, and the 60W USB-C PD port is fast and convenient. It’s heavier at 16.8 pounds, but that’s a fair trade for the extra capacity and the 5-year warranty that gives me real peace of mind.
✅ Pros
- 512Wh capacity is nearly double the 522 — runs larger gear like fridges
- 9 total ports including 4 AC outlets — plenty for group camping
- LiFePO4 battery with InfiniPower tech rated for 10-year lifespan
- Comes with a superior 5-year full-device warranty
❌ Cons
- Heavier at 16.8 pounds — not as portable for hiking or quick trips
- Higher price point means a bigger upfront investment for beginners
- Solar panel is sold separately if you don’t get the bundle
Which One Should You Buy?
I know picking between these two can feel like a toss-up, but the right choice really comes down to what you plan to power. Here’s how I’d match each station to a specific type of buyer.
Anker 522 Portable Power Station is right for you if…
- You only need to charge phones, tablets, and a laptop overnight — its 299Wh capacity and 60W USB-C port handle that easily.
- You want something lightweight for car camping or day trips — at 8.29 pounds it’s easy to carry and won’t take up much trunk space.
- You’re on a tighter budget and want a reliable LiFePO4 battery to start with — this is the most affordable way to get into Anker’s portable power lineup.
Anker 535 Portable Power Station is right for you if…
- You need to run a portable fridge, heater, or TV while camping — its 512Wh capacity and 500W output can handle real appliances.
- You want a power station that can serve as backup power for your home — the 9 ports and 4 AC outlets give you flexibility during outages.
- You plan to use it regularly and want long-term reliability — the 5-year warranty and InfiniPower tech make this a station built to last over a decade.
❌ Who Should Skip All of These?
If you need to power heavy tools like a table saw, a well pump, or run a full home backup for days, neither of these battery stations will cut it. You’d be better off looking at a gas-powered inverter generator or a much larger solar generator setup with 2000Wh or more.
For most beginners just getting into portable power, my honest recommendation is the Anker 535. The 512Wh capacity gives you room to grow into bigger gear, and the 5-year warranty means you won’t outgrow it in a season. But if you’re only charging small electronics and want to keep things simple and light, the Anker 522 is a fantastic entry point.
Frequently Asked Questions
Which is better for camping, the Anker 522 or the Anker 535?
I’d give the edge to the Anker 535 for serious camping. With 512Wh of capacity and 500W of output, it can run a portable fridge, charge phones, and keep lights on for a full weekend without needing a recharge. The 522’s 299Wh works fine for overnight trips where you’re just charging phones and a laptop, but you’ll hit its limits fast if you bring any larger gear.
Is the Anker 535 worth the extra money over the Anker 522?
For me, yes — if you plan to use it for more than just charging small electronics. The 535 gives you nearly double the capacity (512Wh vs 299Wh), more than double the AC outlets (4 vs 2), and a 5-year warranty compared to the 522’s 90-day limited warranty. If you only need to top off your phone and tablet on short trips, the 522 is plenty. But the 535 is a station you can grow into.
How much does each power station weigh and how portable are they?
The Anker 522 weighs just 8.29 pounds, which makes it genuinely easy to carry with one hand or toss in a backpack for a hike. The Anker 535 is heavier at 16.8 pounds — still manageable, but it’s more of a carry with two hands or roll it on a cart situation. If portability is your top priority, the 522 wins hands down.
Can the Anker 522 or 535 run a mini fridge?
The Anker 535 absolutely can — its 500W output and 512Wh capacity will run a 12V mini fridge for about 8 to 10 hours depending on the model. The Anker 522, with only 300W output and 299Wh capacity, will struggle. You might get a few hours out of it with a very small cooler-style fridge, but I wouldn’t rely on it for a full day trip.
How long does it take to recharge each power station?
Both stations can recharge to 80% in about 2.5 hours using the included AC adapter and USB-C port. That’s a real advantage of the newer Anker designs — you’re not stuck waiting all day. If you add a solar panel, the 535 comes with a 100W panel option that also hits 80% in about 2.5 hours in direct sunlight, thanks to its 23% conversion efficiency.
Which one has a better warranty?
The Anker 535 is the clear winner here with a 5-year full-device warranty, which is well above average for portable power stations. The Anker 522 only comes with a 90-day limited warranty since it’s sold through the Amazon Renewed store. If long-term peace of mind matters to you, the 535’s warranty alone could justify the higher price.
My Final Verdict
If you’re a beginner looking for your first portable power station, my winner is the Anker 535. Its 512Wh capacity and 500W output give you room to power real gear like a fridge or TV, and the 5-year warranty means you won’t be shopping for an upgrade next season. The Anker 522 is a solid runner-up for anyone who just needs to charge phones and laptops on lightweight overnight trips, thanks to its 8.29-pound frame and 299Wh battery.
If you’re still on the fence, ask yourself one question: do you see yourself ever wanting to run a mini fridge, heater, or multiple devices at once? If yes, go with the 535. If you’re strictly charging small electronics and want the lightest possible option, the 522 will serve you well.
