I’ve been testing two popular small backup power stations side by side: the Anker 521 Portable Power Station (256Wh, 300W AC output) and the Jackery Explorer 240D Power Bank (256Wh, 200W DC output). Both pack LiFePO4 batteries for long life, but they serve very different needs.
This comparison is for anyone who needs a compact power bank for camping, emergencies, or road trips. The big question is whether you need AC outlets or can live with just USB-C ports. Let me break down exactly which one fits your setup.

Individual Product Breakdown
I tested both of these compact power stations for charging laptops, phones, and small gear to see which one handles real-world use better. Here’s what I found with each.
Anker 521 Portable Power Station Upgraded with LiFePO4 Battery
256Wh | 300W (600W Peak) | 2 AC Outlets | 8.2 lbs

The Anker 521 is the clear winner if you need to power anything with a wall plug. I love that it has two AC outlets plus a 60W USB-C PD port, so I can run a small fan or charge my laptop at the same time. The LiFePO4 battery is rated to last up to 10 years, and the 5-year warranty gives me peace of mind. My only complaint is that at 8.2 pounds, it’s noticeably heavier than the Jackery for backpacking.
β Pros
- 300W AC output with 600W surge for small appliances
- 6 total ports including 2 AC, 2 USB-A, 1 USB-C, 1 car outlet
- LiFePO4 battery lasts up to 10 years with 5-year warranty
- 60W USB-C PD for fast laptop charging
β Cons
- Heavier at 8.2 pounds compared to DC-only rivals
- No 140W USB-C port for ultra-fast device charging
Jackery Explorer 240D Power Bank
256Wh / 80,000mAh | 200W DC Output | 3 USB-C Ports | 4.85 lbs

The Jackery Explorer 240D is incredibly light at just 4.85 pounds, making it the better choice for tossing in a backpack. I was impressed by the three USB-C ports including one that outputs 140W, so it charges my MacBook Pro faster than the Anker can. The 1-hour fast charging from AC-DC dual input is a lifesaver when you’re in a rush. Just remember there are no AC outlets here, so you can’t plug in a lamp or mini fridge.
β Pros
- Ultra-light at 4.85 pounds, 46% lighter than comparable AC stations
- 3 USB-C ports with 140W max output for rapid device charging
- 0-80% charge in 1 hour with AC-DC dual input
- LiFePO4 battery maintains 70% capacity after 6,000 cycles
β Cons
- No AC outlets, so it won’t power standard wall-plug devices
- Only 200W total DC output limits what you can run
Which One Should You Buy?
I’ve spent enough time with both of these to know that the right pick depends entirely on what you plan to plug into it. Let me match you to the best option based on your specific needs.
Anker 521 Portable Power Station is right for you if…
- You need to power small appliances like a fan, CPAP machine, or mini fridge that require a standard 110V AC outlet
- You want a single unit that can charge a laptop via 60W USB-C PD and run a lamp at the same time using the 2 AC ports
- The 5-year warranty and 10-year LiFePO4 lifespan matter more to you than saving a couple of pounds in your bag
Jackery Explorer 240D Power Bank is right for you if…
- You only charge USB devices like phones, tablets, laptops, and drones and want the fastest possible 140W USB-C output
- Weight is your top priority β at 4.85 pounds it’s 41% lighter than the Anker for backpacking or hiking trips
- You need to recharge quickly between stops, since the 240D hits 80% in just 1 hour with AC-DC dual input
β Who Should Skip All of These?
If you need to run power tools, a portable air conditioner, or any device over 300 watts, both of these will fall short. You’d be better off looking at a larger power station with at least 500W of AC output or a gas generator for heavy-duty jobs.
For most people who just want a small backup for phones, laptops, and a few small electronics, I’d recommend the Anker 521 because those two AC outlets give you way more flexibility than the Jackery’s DC-only setup.
Frequently Asked Questions
Which is better for camping, the Anker 521 or Jackery Explorer 240D?
I’d pick the Anker 521 for most camping trips because the two AC outlets let me plug in a string of lights or a small fan. The Jackery is better if you’re backpacking and every ounce counts β it’s only 4.85 pounds versus the Anker’s 8.2 pounds. For car camping where weight isn’t a concern, the Anker’s AC ports give you way more flexibility.
Can the Jackery Explorer 240D power a laptop?
Yes, and it actually does it faster than the Anker 521. The Jackery has a 140W USB-C port that can charge a MacBook Pro at full speed, while the Anker tops out at 60W USB-C PD. Just keep in mind the Jackery has no AC outlets, so you’ll need a USB-C charging laptop or a DC adapter.
Which power station charges faster, the Anker 521 or Jackery 240D?
The Jackery Explorer 240D wins this one hands down. It can go from 0 to 80% in just 1 hour when you use the AC-DC dual input feature. The Anker 521 doesn’t have a fast-charge spec listed, so expect a slower recharge time in comparison. If you’re often in a hurry, the Jackery is the better bet.
Is the Anker 521 worth the extra money over the Jackery Explorer 240D?
That depends entirely on whether you need AC power. The Anker 521 gives you two 110V AC outlets and a 300W output (600W peak), which the Jackery simply doesn’t have. If you ever need to plug in a CPAP machine, a mini fridge, or a power tool charger, the Anker is worth the difference. If you only charge USB devices, save your money and go with the Jackery.
Which one lasts longer, the Anker 521 or Jackery Explorer 240D?
Both use LiFePO4 batteries, so they’re built to last. The Anker 521 is rated for up to 10 years of use with InfiniPower technology and comes with a 5-year warranty. The Jackery Explorer 240D is rated to maintain 70% capacity after 6,000 charge cycles. In real-world terms, both will easily outlast cheaper power stations, but the Anker’s warranty gives you more coverage.
Can I use solar panels with the Anker 521 and Jackery Explorer 240D?
Yes, both support solar charging. The Anker 521 works with optional 100W solar panels (sold separately), and the Jackery Explorer 240D supports up to 100W solar input as well. The Jackery also gives you more charging options with USB-C, car, and AC-DC dual input for faster top-ups when the sun isn’t out.
My Final Verdict
I’m giving the win to the Anker 521 Portable Power Station. That 300W AC output with two outlets is a big improvement for a small backup unit β it powers things the Jackery simply can’t, like a fan or CPAP machine. The Jackery Explorer 240D is still a great choice if you only charge USB devices and want the lightest possible pack at 4.85 pounds, but the Anker’s versatility wins for most buyers.
If you’re still on the fence, ask yourself one question: do you ever need to plug something into a wall outlet? If yes, the Anker 521 is your only real choice here. If all your gear charges via USB-C, grab the lighter, faster-charging Jackery and save a few pounds from your bag.
