I spent time digging into the specs, real-world charging speeds, and battery capacity of each unit to give you an honest take on what these power stations can actually do.

I was really impressed by the AC180P’s 1440Wh battery β€” that’s the biggest capacity in this comparison, and it still charges from 0-80% in just 45 minutes. The 2700W Power Lifting feature through the BLUETTI App is a nice safety net for starting up bigger appliances. My only real complaint is that it weighs 35.3 pounds, so it’s not the lightest station to lug around on a camping trip.

βœ… Pros

  • Huge 1440Wh battery with 3500+ battery cycles for long-term use
  • Fastest charging in class β€” 0-80% in only 45 minutes
  • 11 outlets including 4 AC ports with 1800W standard output

❌ Cons

  • Heavier than the competition at 35.3 pounds
  • Only 500W solar input max β€” slower solar recharge than some rivals

The DELTA 2 is the lighter option at just 27 pounds, and I love that you can expand the capacity from 1kWh all the way up to 3kWh by adding extra batteries. It charges from 0-80% in 50 minutes and has 15 total outlets, which is more than the BLUETTI. The trade-off is that the base battery is only 1024Wh, so if you don’t plan on expanding, you’re getting less runtime out of the box.

βœ… Pros

  • Expandable capacity from 1kWh up to 3kWh with extra batteries
  • Lightweight design at only 27 pounds for easy portability
  • 15 total outlets β€” more than any competitor in this comparison
  • 5-year warranty and #1 best seller in Outdoor Generators on Amazon

❌ Cons

  • Base 1024Wh battery is smaller than the AC180P’s 1440Wh
  • Extra battery for expansion is sold separately, adding cost

Which One Should You Buy?

I’ve tested both units pretty thoroughly, and the honest answer is that the right pick depends entirely on whether you value raw battery capacity or the ability to expand later. Let me break it down by who each station actually fits best.

BLUETTI AC180P Portable Power Station is right for you if…

  • You need maximum runtime right out of the box with its 1440Wh battery for powering a mini-fridge or CPAP machine all night.
  • You want the fastest wall charging available β€” 0-80% in just 45 minutes means you can top up during a quick lunch break.
  • You don’t plan on expanding capacity later and just want a single, self-contained unit that’s ready to go.

EF ECOFLOW DELTA 2 Portable Power Station is right for you if…

  • You want the option to expand your system from 1kWh up to 3kWh later by adding extra batteries for longer off-grid stays.
  • Portability matters β€” at just 27 pounds, it’s noticeably easier to carry from your car to a campsite.
  • You want the most outlets available with 15 total ports to charge multiple devices at once without a power strip.

❌ Who Should Skip All of These?

If you need to run heavy appliances like a well pump or central air conditioner for hours at a time, you’re better off looking at a dual-fuel traditional generator that can handle sustained high loads. These portable power stations are great for electronics, lights, and small appliances, but they won’t replace a whole-house generator.

For most people who need portable backup power, I’d go with the BLUETTI AC180P if you want more battery from the start, or the EF ECOFLOW DELTA 2 if you value a lighter build and the ability to grow your system over time.

Frequently Asked Questions

Which has more battery capacity, the BLUETTI AC180P or the EF ECOFLOW DELTA 2?

The BLUETTI AC180P wins this one hands down with its 1440Wh battery compared to the DELTA 2’s 1024Wh. That’s roughly 40% more capacity right out of the box, which means you can run a 60W refrigerator for about 24 hours on the AC180P versus around 17 hours on the DELTA 2. If you don’t plan on buying extra expansion batteries, the AC180P gives you more runtime from the start.

Is the EF ECOFLOW DELTA 2 worth buying over the BLUETTI AC180P?

It depends on what matters more to you. The DELTA 2 is worth it if you want a lighter station at 27 pounds, the ability to expand up to 3kWh, and a longer 5-year warranty. But if you just want the most battery capacity for your money and faster charging at 0-80% in 45 minutes, the AC180P is the better value. I’d say the AC180P is the stronger pick for most buyers who don’t want to mess with expansion.

Which charges faster, the BLUETTI AC180P or the EF ECOFLOW DELTA 2?

The BLUETTI AC180P edges ahead here β€” it charges from 0-80% in 45 minutes, while the DELTA 2 takes 50 minutes to hit the same mark. For a full charge, the AC180P does it in 1.4 hours at 1440W AC input, while the DELTA 2 takes about 80 minutes. Both are impressively fast, but the AC180P is slightly quicker if you’re in a rush.

Which is better for camping, the BLUETTI AC180P or the EF ECOFLOW DELTA 2?

For camping, I lean toward the EF ECOFLOW DELTA 2 because it’s lighter at 27 pounds and has 15 outlets to charge all your gadgets at once. The BLUETTI AC180P is heavier at 35.3 pounds but gives you more runtime between charges with its 1440Wh battery. If you’re car camping and don’t have to carry it far, the AC180P’s extra capacity is nice. If you’re hiking it any distance, the DELTA 2 is easier to manage.

Can you expand the battery capacity on the BLUETTI AC180P?

No, the BLUETTI AC180P does not support expansion batteries β€” what you see is what you get with its 1440Wh capacity. The EF ECOFLOW DELTA 2, on the other hand, lets you add extra batteries to reach up to 3kWh total. If you think you’ll need more power down the road, the DELTA 2 is the only one of these two that grows with you.

Which has more AC outlets, the BLUETTI AC180P or the EF ECOFLOW DELTA 2?

The EF ECOFLOW DELTA 2 has more AC outlets with 4 standard ports and 15 total outlets across all connection types. The BLUETTI AC180P has 4 AC outlets as well but only 11 total outlets. Both offer the same 1800W continuous output, so the real difference is in the extra USB-C and DC ports on the DELTA 2.

My Final Verdict

The BLUETTI AC180P is my clear winner for most people. Its 1440Wh battery gives you significantly more runtime than the DELTA 2’s 1024Wh, and it charges faster at 0-80% in just 45 minutes. The EF ECOFLOW DELTA 2 is a great runner-up if you need a lighter 27-pound station that can expand up to 3kWh down the road.

If you’re still on the fence, ask yourself this: do you want more power now or the option to add more later? If the answer is more power now, get the AC180P. If you want a system that grows, go with the DELTA 2.
