Individual Product Breakdown
I put each of these power stations through its paces — checking battery capacity, AC output, charging speed, and real-world usability for camping and home backup. Here’s what I found for each one.
EF ECOFLOW DELTA 3 1000 Air Portable Power Station
960Wh LFP Battery | 500W AC Output | 10ms UPS | 22 lbs

The EF ECOFLOW DELTA 3 1000 Air impressed me right away with its 960Wh capacity — that’s the biggest battery of the three by a solid margin. I love that it recharges fully in just 2 hours with AC power, and the 10ms UPS switchover means your gear never blinks during an outage. The trade-off is that the AC output is limited to 500W, so you won’t be running big power tools, but it handles home essentials like lights, fans, and a fridge without breaking a sweat.
✅ Pros
- Largest capacity at 960Wh — runs a fridge for hours
- Ultra-fast 2-hour AC recharge
- 10ms UPS keeps sensitive electronics safe
- Compact design at just 8.7 x 8.8 x 10.4 inches
❌ Cons
- Only 500W AC output — not for high-wattage appliances
- No app control or built-in storage compartment
BLUETTI AC70 Portable Power Station
768Wh LFP Battery | 1000W AC (2000W Lifting) | ≤20ms UPS | 22.5 lbs
- [Power for All Essentials] - With a capacity of 768Wh, 1000W inverter and...
- [1.5 Hours AC Charging] - No bulky power adapter, a single cable is enough...
- [Up to 500W Solar] - Fully charge the AC70 solar generator in 1.9-2.4 hours...
The BLUETTI AC70 is a fantastic all-rounder that I’d recommend to anyone who needs more raw AC power. Its 1000W inverter can surge to 2000W with power lifting, which means it’ll start up a small fridge or a power tool that the EcoFlow can’t touch. The 768Wh capacity is solid, and I appreciate the ≤20ms UPS backup and the ability to recharge from 0-80% in just 45 minutes. My main gripe is that the battery is 192Wh smaller than the EcoFlow, so it won’t run your gear quite as long on a single charge.
✅ Pros
- 1000W AC output with 2000W power lifting
- Fast 45-minute charge to 80%
- App remote control for monitoring
- ≤20ms UPS backup for sensitive devices
❌ Cons
- 768Wh battery is smaller than the EcoFlow’s 960Wh
- Heavier than the competition at 22.5 lbs

- Fully Power Multiple Appliances: No more compromising. Plug in multiple...
- More Power and More Ports: Plug in up to 10 appliances all at once and...
- Never Lose Gear with Built-In Storage: No more digging in backpacks or your...
The Anker SOLIX C800 blew me away with its charging speed — a full recharge in just 58 minutes is the fastest of the bunch by a long shot. It also packs the most AC power here at 1200W (1600W peak with SurgePad), so it can run more demanding appliances than the other two. The 768Wh battery matches the BLUETTI, and I love the built-in storage compartment for stashing small devices. The only downside is that solar input is limited to 300W, which is lower than the 500W the EcoFlow and BLUETTI can handle.
✅ Pros
- Blazing fast 58-minute full recharge
- 1200W AC output (1600W peak) — most powerful here
- Built-in storage compartment for small gear
- InfiniPower tech for 3,000+ battery cycles
❌ Cons
- Solar input limited to 300W — slower solar recharge
- Battery capacity is 192Wh less than the EcoFlow
Which One Should You Buy?
I know choosing between three solid power stations can feel overwhelming, but the right pick really comes down to what you value most. Here’s how I’d break it down for different situations.
EF ECOFLOW DELTA 3 1000 Air is right for you if…
- You need the longest runtime for home essentials like a fridge or fan — its 960Wh battery is the biggest here
- You want a UPS with 10ms switchover to keep your computer or router running during a brownout
- You value a compact, lightweight design at 22 lbs that’s easy to carry around the house or campsite
BLUETTI AC70 is right for you if…
- You need 1000W of continuous AC power with 2000W lifting capability to start up a fridge or a small power tool
- You want app control to monitor and adjust settings from your phone
- You’re in a hurry and need a 45-minute charge to 80% before heading out the door
Anker SOLIX C800 is right for you if…
- You absolutely need the fastest recharge — a full 0-100% in just 58 minutes is unbeatable
- You want the most AC power at 1200W (1600W peak) to run a wider range of appliances
- You like the built-in storage compartment to keep small devices organized and safe
❌ Who Should Skip All of These?
If you need to run a heavy-duty appliance like a full-size air conditioner, a well pump, or a large power saw, these portable stations won’t cut it — you’re better off looking at a dual-fuel gas or propane generator with much higher wattage. Also, if you plan to live off-grid for days at a time, you’ll want a larger setup like an EcoFlow DELTA Pro or a whole-home battery system that can handle more solar input and storage expansion.
For the most common buyer — someone who needs reliable backup for a weekend camping trip or to keep a fridge running during a short outage — the EF ECOFLOW DELTA 3 1000 Air is my top pick thanks to its 960Wh battery, compact size, and 10ms UPS protection. It’s the best balance of capacity, portability, and value in this group.
Frequently Asked Questions
Which is better for camping — the EcoFlow DELTA 3 1000 Air or the BLUETTI AC70?
For camping, I’d give the edge to the EcoFlow DELTA 3 1000 Air because its 960Wh battery gives you more runtime for lights, a cooler, and charging phones overnight. The BLUETTI AC70 does have a stronger 1000W inverter, but most camping gear doesn’t need that much power. The EcoFlow is also slightly more compact at 8.7 x 8.8 x 10.4 inches, which makes it easier to pack in the car.
Is the Anker SOLIX C800 worth the extra money over the BLUETTI AC70?
I think it depends on how much you value charging speed. The Anker SOLIX C800 recharges fully in 58 minutes, which is faster than the BLUETTI AC70’s 1.5 hours for a full charge. The Anker also has a higher 1200W AC output compared to the BLUETTI’s 1000W. But both have the same 768Wh battery capacity, so runtime is nearly identical — you’re really paying for that extra speed and power.
Which power station has the longest battery life?
The EF ECOFLOW DELTA 3 1000 Air wins this one hands down with its 960Wh battery. That’s 192Wh more than both the BLUETTI AC70 and the Anker SOLIX C800, which both pack 768Wh. In real terms, that extra capacity means the EcoFlow can run a 60W fridge for about 16 hours, while the other two would tap out closer to 12.8 hours.
Can these power stations run a refrigerator during a power outage?
Yes, all three can run a standard mini-fridge or an energy-efficient full-size refrigerator. The EF ECOFLOW DELTA 3 1000 Air’s 500W output is enough for most fridges, but the BLUETTI AC70 and Anker SOLIX C800 have a higher 1000W and 1200W output respectively, which gives you more headroom for the compressor startup surge. The EcoFlow will run it the longest thanks to its 960Wh capacity, while the Anker will recharge the fastest when the power comes back.
Which one is best for solar charging?
If you’re planning to rely on solar panels, I’d pick the EF ECOFLOW DELTA 3 1000 Air or the BLUETTI AC70, since both can handle up to 500W of solar input. The Anker SOLIX C800 is limited to 300W, which means slower solar recharge times. The BLUETTI AC70 can fully charge from solar in about 1.9 to 2.4 hours with a 500W panel, while the Anker would take around 2.3 hours to reach 80% with its max 300W input.
Which power station has the fastest AC recharge time?
The Anker SOLIX C800 is the clear winner here — it goes from 0 to 100% in just 58 minutes with UltraFast charging mode. The EF ECOFLOW DELTA 3 1000 Air takes about 2 hours for a full charge, and the BLUETTI AC70 takes 1.5 hours (reaching 80% in 45 minutes). If speed is your top priority, the Anker is the one to get.
My Final Verdict
After testing all three, the EF ECOFLOW DELTA 3 1000 Air is my clear overall winner. Its 960Wh battery gives you the longest runtime of the bunch, the 10ms UPS switchover protects your sensitive gear, and it’s surprisingly compact at just 22 pounds. The Anker SOLIX C800 is the best runner-up if you prioritize raw AC power and super-fast charging — its 1200W output and 58-minute recharge are hard to beat.
If you’re still on the fence, ask yourself this: do you need more runtime or more power? For most people camping or dealing with short outages, the EcoFlow’s extra 192Wh of battery will make a bigger real-world difference than a few extra watts of AC output. That’s why it gets my top recommendation.
