I’ve been testing three compact power stations for short trips: the Anker 521 (256Wh, 300W), the BLUETTI AC2A (204Wh, 300W), and the new Jackery Explorer 240D (256Wh, 200W DC output). They’re all built with LiFePO4 batteries, but each takes a different approach to keeping your gear charged.
If you’re heading out for a weekend camping trip or just want backup power for a road trip, the big trade-off here is AC outlets versus size and weight. I’ve spent time with all three, and I’ll break down exactly which one fits your packing list.

Individual Product Breakdown
I ran each of these three power stations through a weekend of light camping and device charging to see how they handle real-world short trips. Here’s what I found.
Anker 521 Portable Power Station Upgraded with LiFePO4 Battery
256Wh | 300W (600W Peak) | 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 most well-rounded option for short trips if you need actual AC power. The 256Wh capacity and 300W inverter handled my laptop, phone, and a small fan without breaking a sweat, and the 60W USB-C PD port charged my laptop faster than I expected. It weighs 8.2 pounds, which is a bit heavier than the others, but the 5-year warranty gives me peace of mind. My only real gripe is that it takes longer to recharge than the BLUETTI AC2A.
β Pros
- 256Wh capacity with 2 AC outlets for true appliance power
- 60W USB-C PD output for fast laptop charging
- 5-year warranty and LiFePO4 battery for long life
- SurgePower handles up to 600W peak for small appliances
β Cons
- Heavier than competitors at 8.2 pounds
- No fast recharge mode like the BLUETTI’s 40-minute option
BLUETTI AC2A Portable Power Station
204Wh | 300W (600W Lifting) | 2 AC Outlets | 7.9 lbs
- [Light and Portable] - Weighing only 9.4 lbs, this entry-level unit blends...
- [9 Outputs & 1500W Power Lifting] - 9 outputs deliver 600W for camping...
- [50% Lower Power Consumption] - Upgraded with UltraCell tech and smart...
The BLUETTI AC2A is my pick if speed matters most. It recharges from 0 to 80% in just 40 minutes using its 270W Turbo Charging, which is way faster than the Anker 521. The 204Wh capacity is a bit smaller, but the 600W power lifting feature lets it handle small appliances that would stall other 300W inverters. It also has app control for remote monitoring. The downside is that 204Wh won’t last as long as the 256Wh units if you’re running multiple devices.
β Pros
- 0-80% charge in 40 minutes with Turbo Charging
- 600W power lifting for small appliances
- App remote control for monitoring and settings
- Lightweight at 7.9 pounds
β Cons
- Only 204Wh capacity β less runtime than the Anker 521
- No 60W USB-C PD port for fast laptop charging
Jackery Explorer 240D Power Bank

If weight is your main concern, the Jackery Explorer 240D is a big improvement at just 4.85 pounds. It packs the same 256Wh capacity as the Anker 521 but in a much smaller package, and the 140W USB-C port charges my laptop in no time. The catch is there are no AC outlets β it’s a DC-only power bank, so you can’t plug in anything that uses a wall plug. It’s perfect for charging phones, tablets, laptops, and drones on a short hiking trip, but not for running a mini-fridge or CPAP machine.
β Pros
- Ultra-light at 4.85 pounds with 256Wh capacity
- 140W USB-C output for fast laptop charging
- 0-80% charge in 1 hour with AC-DC dual input
- LiFePO4 battery lasts 6,000+ cycles
β Cons
- No AC outlets β DC output only at 200W
- Can’t power small appliances or devices with wall plugs
Which One Should You Buy?
I know every short trip is different, so I’ve broken down exactly which buyer each station suits best. Here’s who I’d send to each one.
Anker 521 Portable Power Station is right for you if…
- You need to power small appliances like a fan or mini-fridge with the 2 AC outlets and 300W inverter
- You want the best balance of 256Wh capacity and AC power without adding too much weight at 8.2 pounds
- You value a 5-year warranty and LiFePO4 battery that lasts up to 10 years
BLUETTI AC2A Portable Power Station is right for you if…
- You need a power station that recharges fast β 0 to 80% in 40 minutes with Turbo Charging
- You want to run small appliances that need a startup surge, thanks to the 600W power lifting feature
- You like controlling your station from your phone with the BLUETTI App for remote monitoring
Jackery Explorer 240D Power Bank is right for you if…
- Weight is your top priority β at 4.85 pounds it’s the lightest way to carry 256Wh of power
- You only need to charge USB devices like laptops, phones, tablets, and drones with the 140W USB-C port
- You want a power bank that charges quickly from 0 to 80% in 1 hour using AC-DC dual input
β Who Should Skip All of These?
If you need to run a CPAP machine all night, power a mini-fridge for a weekend, or run any device that draws over 300W continuously, you’ll want a larger station with at least 500Wh capacity and a bigger inverter. These three are strictly for light device charging and small electronics on short trips.
For most people taking a weekend camping trip or road trip who need to charge laptops, phones, and maybe a small fan, I’d grab the Anker 521 β it gives you the best mix of capacity, AC outlets, and durability without breaking the bank.
Frequently Asked Questions
Which is better for a weekend camping trip, the Anker 521 or the BLUETTI AC2A?
I’d take the Anker 521 for a weekend trip because its 256Wh capacity gives you more runtime than the BLUETTI’s 204Wh. If you’re running a laptop and charging phones for two days, that extra 52Wh makes a real difference. The BLUETTI AC2A is better if you know you’ll have access to wall power during the day and want to top up fast in 40 minutes.
Is the Jackery Explorer 240D worth it over the Anker 521 if I only charge USB devices?
Yes, absolutely β the Explorer 240D is lighter at 4.85 pounds compared to the Anker’s 8.2 pounds, and it still has the same 256Wh capacity. You also get a faster 140W USB-C output versus the Anker’s 60W USB-C PD, so your laptop will charge quicker. Just remember you’re giving up the two AC outlets, so if you ever need to plug in a wall-powered device, the Anker is the better choice.
Which power station recharges the fastest?
The BLUETTI AC2A wins here by a long shot. It goes from 0 to 80% in just 40 minutes using its 270W Turbo Charging, and it’s fully charged in about 70 minutes. The Jackery Explorer 240D takes about 1 hour to hit 80% with AC-DC dual input. The Anker 521 is the slowest of the three with no fast charging mode mentioned in its specs.
Can the Jackery Explorer 240D power a mini-fridge or CPAP machine?
No, it can’t β the Explorer 240D only has DC output with no AC outlets, so it won’t power anything that uses a standard wall plug. You’d need the Anker 521 or BLUETTI AC2A for that, since both have two AC outlets and a 300W inverter. The Anker’s 256Wh capacity is also better suited for running a small CPAP machine for a single night.
Which one has the longest battery lifespan?
The Jackery Explorer 240D has the longest lifespan at over 6,000 charge cycles before dropping to 70% capacity. The Anker 521 and BLUETTI AC2A both use LiFePO4 batteries too, but the Anker is rated for up to 10 years of use, while the BLUETTI is rated for 3,000+ cycles. All three will last years for short trips, but the Jackery is the clear winner if you want the most cycles.
Is the BLUETTI AC2A’s 600W power lifting a gimmick or actually useful?
It’s genuinely useful for small appliances that need a startup surge, like a mini-fridge or a small pump. The 300W inverter can briefly handle up to 600W to get those motors spinning, then settle back to normal. That said, it won’t run a 600W appliance continuously β it’s just a temporary boost to handle startup spikes that would shut down the Anker 521’s inverter.
My Final Verdict
For short trips, the Anker 521 is my clear overall winner β it gives you 256Wh of capacity, two AC outlets, and a 60W USB-C PD port in a package that’s versatile enough for almost anyone. The BLUETTI AC2A is the runner-up if you prioritize speed, with its 40-minute recharge time and 600W power lifting for small appliances. The Jackery Explorer 240D is the specialist choice for ultralight packing at just 4.85 pounds, but you pay for that with no AC outlets.
If you’re still on the fence, ask yourself one question: do you need to plug anything into a wall outlet? If yes, go with the Anker 521. If you only charge USB devices and want the lightest bag possible, the Jackery Explorer 240D is your match. Don’t overthink it β the right pick is the one that matches the gear you actually carry.
