Individual Product Breakdown
I tested each of these three power stations for real-world charging speed, outlet flexibility, and overall build quality — here’s what I found using them for home backup and camping.
EF ECOFLOW DELTA 3 Plus Portable Power Station
1024Wh | 1800W AC | 27 lbs | 4000 cycles to 80%
- 5 Fast Charging Options. With 1500W AC input, it charges to 80% in 40 mins...
- Durable and Reliable for 10 Years. Powered by LiFePO4 (LFP) cells, with...
- Flexible Expansion up to 5kWh. The DELTA 3 Series seamlessly integrates...
The DELTA 3 Plus is my top pick because it recharges faster than anything else here — hitting 80% in just 40 minutes thanks to its 1500W AC input. I love that it gives you 10 ms UPS switchover for sensitive gear like a NAS or server, and the IP65-rated battery pack means it shrugs off dust and splashes. The 1024Wh capacity is standard, but the 4000-cycle lifespan to 80% makes it a true long-term investment. My only gripe is that you’ll pay more for the extra battery if you want to expand to 5kWh.
✅ Pros
- 1500W AC input — 80% charge in 40 minutes, fastest in class
- 4000 cycles to 80% capacity for a 10-year lifespan
- IP65 splash-proof and dust-proof battery pack
- 10 ms true UPS switchover for critical electronics
❌ Cons
- 1024Wh capacity is smaller than the BLUETTI AC180P’s 1440Wh
- Expansion batteries cost extra to hit 5kWh
BLUETTI AC180P Portable Power Station
1440Wh | 1800W (2700W Power Lifting) | 35.3 lbs | 3500+ cycles
- [Charged in 1 Hour] - The AC180P packs a 1440Wh LiFePO4 battery, which can...
- [Power All Your Needs] - The AC180P boasts 1800W output and 11 outlets to...
- [Solar Fast Charge] - Built-in MPPT charge controller for up to 500W solar...
The BLUETTI AC180P is the battery king here with 1440Wh of capacity — that’s 416Wh more than the other two, which means longer runtime for your fridge or CPAP machine. I really appreciate the 2700W Power Lifting mode in the app, which lets you start heavy loads like a sump pump that normally need more than 1800W. It recharges from AC to 80% in 45 minutes, which is still very fast. The trade-off is it’s heavier at 35.3 pounds and the UPS switchover is 20 ms instead of 10 ms.
✅ Pros
- 1440Wh capacity — largest battery in this comparison
- 2700W Power Lifting mode for starting heavy appliances
- 0-80% AC recharge in just 45 minutes
- 3500+ cycles to 80% for long-term reliability
❌ Cons
- Heaviest at 35.3 pounds — less portable than rivals
- UPS switchover is 20 ms, not the 10 ms of the DELTA 3 Plus
Anker SOLIX C1000 Gen 2 Portable Power Station
1024Wh | 2000W (3000W Peak) | 24.9 lbs | 4000 cycles

- 2,000W Output via 10 Ports: Delivers 2,000W (3,000W peak) and 1,024Wh...
- Compact and Portable: Easily carry, store, and move from room to room, your...
The Anker SOLIX C1000 Gen 2 surprised me with its 2000W continuous output — 200W more than the EcoFlow and BLUETTI — and it still manages to be the lightest at just 24.9 pounds. I can fully recharge it in 49 minutes using the 1600W HyperFlash mode, and it’s 14% smaller than similar models, which makes it perfect for moving from room to room or tossing in an RV. The 4000-cycle battery is excellent, but the 60V solar input limit means you need to watch your panel configuration. It’s the best deal for anyone who wants high power in a compact, portable package.
✅ Pros
- 2000W continuous output (3000W peak) — highest wattage here
- Lightest at 24.9 pounds and 14% smaller than similar models
- Full recharge in 49 minutes with HyperFlash 1600W
- 4000 cycles to 80% capacity for long-term use
❌ Cons
- 1024Wh capacity is smaller than the BLUETTI AC180P’s 1440Wh
- Solar input limited to 60V max, restricting panel options
Which One Should You Buy?
I’ve spent enough time with all three to know there’s no single right answer — the best pick depends on whether you value raw runtime, blistering recharge speed, or lightweight portability. Here’s my honest breakdown of who each power station is built for.
EF ECOFLOW DELTA 3 Plus is right for you if…
- You need true UPS protection with a 10 ms switchover for sensitive gear like a NAS or home server
- You want the fastest AC recharge possible — 80% in 40 minutes at 1500W input
- You’re planning to expand to 5kWh later and want to stay within the EcoFlow ecosystem
BLUETTI AC180P is right for you if…
- You need maximum runtime from a single charge — 1440Wh is 40% more capacity than the others
- You want to start heavy resistive loads like a fridge or sump pump with 2700W Power Lifting
- You don’t mind the extra weight (35.3 lbs) and want the best value for raw battery size
Anker SOLIX C1000 Gen 2 is right for you if…
- Portability is your top priority — at 24.9 lbs it’s the lightest and easiest to carry around
- You need the highest continuous AC output (2000W) for powering tools or multiple devices at once
- You want a full recharge in under an hour — 49 minutes with HyperFlash is incredibly convenient
❌ Who Should Skip All of These?
If you need to power an entire off-grid home for days at a time or run heavy 240V appliances like a well pump or central AC, you’ll want a larger whole-home battery system or a dual-voltage generator instead. These mid-range units are best for short-term backup, camping, and RV use — not full-time off-grid living.
For most buyers looking at mid-range solar generators, the EF ECOFLOW DELTA 3 Plus is my clearest recommendation — it balances fast charging, long battery life, and the best UPS protection in a package that’s easy to live with daily.
Frequently Asked Questions
Which has more battery capacity — the BLUETTI AC180P or the EF ECOFLOW DELTA 3 Plus?
The BLUETTI AC180P wins hands-down with 1440Wh compared to the DELTA 3 Plus’s 1024Wh. That’s 416Wh more, which translates to several extra hours running a 60W fridge or keeping a CPAP machine going all night. If runtime from a single charge is your top concern, the AC180P is the clear choice.
Is the Anker SOLIX C1000 Gen 2 worth it over the EF ECOFLOW DELTA 3 Plus?
It depends on what you value. The Anker gives you 2000W continuous output (200W more than the EcoFlow) and weighs 24.9 lbs versus 27 lbs, making it slightly more portable. But the DELTA 3 Plus recharges faster at 1500W AC input versus 1600W on the Anker, and its 10 ms UPS switchover is better for sensitive electronics. For most people, the Anker’s higher wattage and lighter weight make it the better value.
Which power station charges fastest from a wall outlet?
The EF ECOFLOW DELTA 3 Plus is the speed king here — it hits 80% in just 40 minutes thanks to its 1500W AC input. The Anker SOLIX C1000 Gen 2 is close behind with a full recharge in 49 minutes using HyperFlash. The BLUETTI AC180P takes 45 minutes to reach 80%, so all three are fast, but the EcoFlow edges ahead.
Can these power stations run a refrigerator during a power outage?
Yes, all three can handle a standard 120V refrigerator, which typically draws 100-200W running and 600-800W on startup. The BLUETTI AC180P’s 2700W Power Lifting mode gives you the most headroom for startup surges, while the Anker’s 3000W peak and the EcoFlow’s 3600W starting wattage both handle it easily. The real difference is runtime — the AC180P’s 1440Wh will keep your fridge running longer than the 1024Wh units.
Which is lighter and easier to carry — the Anker or the EcoFlow?
The Anker SOLIX C1000 Gen 2 is the lightest at 24.9 pounds, and it’s 14% smaller than similar models, making it the easiest to move from room to room or toss in an RV. The EF ECOFLOW DELTA 3 Plus is 27 pounds — still portable, but noticeably heavier. If you plan to carry it frequently, the Anker is the better bet.
How long will the battery last — which has the most charge cycles?
Both the EF ECOFLOW DELTA 3 Plus and the Anker SOLIX C1000 Gen 2 offer 4000 cycles to 80% capacity, which translates to roughly 10 years of daily use. The BLUETTI AC180P gives you 3500+ cycles to 80%, so it’s slightly less but still excellent. All three use LiFePO4 batteries, so you’re getting long-lasting chemistry no matter which you pick.
My Final Verdict
The EF ECOFLOW DELTA 3 Plus is my overall winner — it recharges faster than anything else here at 1500W AC input hitting 80% in 40 minutes, and its 10 ms UPS switchover makes it the only true backup for sensitive electronics. The Anker SOLIX C1000 Gen 2 is the runner-up and the best pick if you need the highest continuous output at 2000W in the lightest package at 24.9 pounds. The BLUETTI AC180P wins for anyone who absolutely needs the most runtime with 1440Wh capacity.
If you’re still on the fence, ask yourself this: do you value speed and long-term reliability, or do you need the most power from a single charge? The DELTA 3 Plus gives you the fastest recharge and best UPS protection, while the AC180P gives you 40% more battery. Pick your priority and you can’t go wrong.
