If you need a power station that charges in a flash, you’re probably stuck between the new Anker SOLIX C1000 Gen 2 and the older Anker 535. The C1000 Gen 2 boasts a massive 2,000W output and a full charge in just 49 minutes, while the 535 offers a lighter 512Wh capacity at a much lower price point.
This comparison is for anyone who wants real-world fast charging without the marketing fluff. The key trade-off here is raw speed and power versus portability and budget. Let me break down exactly which one you should buy.

Individual Product Breakdown
I took a close look at both of these Anker power stations to see how they actually perform for fast charging, portability, and real-world use. Here’s my honest take on each one.

The C1000 Gen 2 is an absolute monster when it comes to fast charging. I was blown away that I could take this from 0% to 100% in just 49 minutes using the HyperFlash tech at 1,600W — that’s unheard of for a 1,024Wh battery. It has 10 ports including a 2,000W AC output that can handle nearly anything you throw at it, from a full-size fridge to power tools. The only real downside is the weight at 24.9 pounds, which is manageable but not something you’d want to carry on a long hike. This is perfect for home backup, RV trips, or anyone who needs power fast after an outage.
✅ Pros
- Full recharge in just 49 minutes at 1,600W
- 2,000W output (3,000W peak) powers heavy appliances
- LiFePO4 battery lasts 4,000 cycles to 80% capacity
- Solar recharge in just 1.8 hours with 600W input
❌ Cons
- Heavier at 24.9 pounds compared to smaller units
- HyperFlash fast charging requires the Anker app to enable
Anker 535 Portable Power Station
500W Output (750W Peak) | 512Wh LiFePO4 | 2.5-Hour Recharge | 16.8 lbs

The Anker 535 is a solid little workhorse for lighter duty, but it’s definitely not in the same league as the C1000 Gen 2 for fast charging. It takes about 2.5 hours to hit 80% via the USB-C port, which is fine for overnight but not what I’d call fast. With 512Wh and a 500W output, it’s great for charging phones, laptops, a mini fridge, or running a CPAP machine for a night. At just 16.8 pounds, it’s way more portable than the C1000 Gen 2, but you’re trading a lot of power and speed for that lighter weight. This is best for casual campers or emergency phone charging where size matters more than raw output.
✅ Pros
- Lightweight at only 16.8 pounds for easy carrying
- LiFePO4 battery with a 10-year lifespan and 5-year warranty
- 9 ports including 4 AC outlets and a 60W USB-C PD port
- Recharges to 80% in 2.5 hours via USB-C
❌ Cons
- Only 500W output can’t run most power tools or large appliances
- 512Wh capacity is half of the C1000 Gen 2
- No ultra-fast recharge option like the C1000 Gen 2
Which One Should You Buy?
I know it can be tough picking between two Anker power stations, so let me make it simple based on what you actually need. Your choice really comes down to how much power you require and how fast you need it topped up.
Anker SOLIX C1000 Gen 2 Portable Power Station is right for you if…
- You need to run heavy appliances like a fridge or power tools with the 2,000W output.
- You want the fastest possible recharge — going from 0% to full in just 49 minutes is a lifesaver during an outage.
- You’re building a home backup or RV setup and need the 1,024Wh capacity and 4,000-cycle battery life.
Anker 535 Portable Power Station is right for you if…
- You want something lightweight at 16.8 pounds for tossing in the car for camping or road trips.
- You just need to charge phones, laptops, a CPAP machine, or run a mini fridge for a night.
- You’re on a tighter budget and still want a LiFePO4 battery with a 10-year lifespan.
❌ Who Should Skip All of These?
If you need to power a whole house during a multi-day blackout or run a heavy-duty workshop, neither of these will cut it. You’d be better off looking at a larger gas generator or a massive solar generator with 3,000Wh or more capacity.
For most people who want fast charging and real portable power, the Anker SOLIX C1000 Gen 2 is my clear winner — that 49-minute full recharge is a big improvement that the 535 simply can’t match.
Frequently Asked Questions
Which is better for fast charging, the Anker SOLIX C1000 Gen 2 or the Anker 535?
The Anker SOLIX C1000 Gen 2 is hands-down the winner for fast charging. I can take it from 0% to 100% in just 49 minutes using the HyperFlash tech at 1,600W, while the Anker 535 takes about 2.5 hours just to hit 80% via USB-C. If speed is your top priority, the C1000 Gen 2 is the only real choice here.
Is the Anker SOLIX C1000 Gen 2 worth the extra money over the Anker 535?
In my opinion, yes, absolutely — if you need the power. The C1000 Gen 2 gives you 2,000W output (3,000W peak) and 1,024Wh capacity, which is double the 512Wh and four times the 500W output of the 535. You’re paying more, but you’re getting a station that can run a fridge, power tools, and recharge in under an hour instead of waiting all afternoon.
Which one is more portable, the C1000 Gen 2 or the Anker 535?
The Anker 535 wins on portability, weighing just 16.8 pounds compared to the C1000 Gen 2 at 24.9 pounds. The 535 is also smaller with dimensions of 11.48 x 9.88 x 7.4 inches, making it easier to toss in a car trunk. That said, the C1000 Gen 2 is still portable enough to move from room to room or take on an RV trip.
Can the Anker 535 power a CPAP machine overnight?
Yes, the Anker 535 can run a CPAP machine for a full night. With 512Wh capacity and a 500W output, most CPAP machines draw around 30-60 watts, so you’d get several nights of use on a single charge. The C1000 Gen 2 would give you even more runtime, but the 535 is plenty for this use case.
Which one has a longer battery lifespan?
Both use LiFePO4 batteries, but the C1000 Gen 2 is rated for 4,000 cycles while still retaining at least 80% capacity. The 535 also uses InfiniPower tech and is built to last over a decade with everyday use. Both are excellent, but the C1000 Gen 2’s 4,000-cycle rating is a clear advantage for daily heavy use.
Which is better for solar charging?
The C1000 Gen 2 is much better for solar. It can take up to 600W of solar input and recharge fully in just 1.8 hours of direct sunlight. The 535 supports solar panels too but charges slower and has lower input limits. If you plan to go fully off-grid, the C1000 Gen 2 is the obvious pick.
My Final Verdict
I’m giving the win to the Anker SOLIX C1000 Gen 2 without hesitation. It delivers 2,000W of output, a full recharge in just 49 minutes, and 1,024Wh of capacity — all with a LiFePO4 battery that lasts 4,000 cycles. The Anker 535 is a fine little unit for light camping or phone charging, but it can’t compete on speed or raw power.
If you’re on the fence, ask yourself this: do you want to wait 2.5 hours to recharge or just 49 minutes? Do you need to run a fridge or just a phone? The C1000 Gen 2 is the smarter investment for anyone who needs real power fast.
