I’ve spent time testing both the EF ECOFLOW DELTA 3 1000 Air and the BLUETTI AC70, and honestly, choosing between them comes down to what you value more: a super compact 22-pound unit with 960Wh of capacity, or a 22.5-pound station with a beefier 1000W inverter that can handle bigger appliances.
If you’re a camper or someone prepping for short power outages and you want the lightest possible setup without sacrificing battery size, this comparison is for you. The real trade-off here is raw output power versus overall capacity and portability.

This is the battery champ of the two. With a 960Wh capacity packed into a unit that’s just 22 pounds and roughly the size of a rice cooker, it’s incredibly easy to move around. I love the 10ms UPS switchover, which means my computer never blinks during an outage, and the X-Stream fast AC charging gets it fully juiced in only 2 hours. The downside is the 500W AC output — even with X-Boost, you won’t run a full-size fridge or power tools without some limitations. This is best for keeping lights, fans, and small electronics running all night long.
✅ Pros
- 960Wh capacity is the largest in this weight class — great for overnight camping
- Fully recharges in just 2 hours via AC, so it’s ready fast
- Ultra-compact at 8.7 x 8.8 x 10.4 inches, easy to stow anywhere
- 10ms UPS backup keeps sensitive electronics running without interruption
❌ Cons
- 500W AC output is lower than the competition — can’t run larger appliances
- Only 3 power outlets limits how many devices you can plug in at once
BLUETTI AC70 Portable Power Station
768Wh LFP Battery | 1000W AC / 2000W Power Lifting | 22.5 lbs | 45 Min to 80%
- [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...
If raw power is your priority, this is the one. The BLUETTI AC70 cranks out a true 1000W continuously, plus a 2000W power lifting mode that can briefly handle things like a small microwave or a refrigerator compressor. I was impressed by the fast charging — it hits 80% in just 45 minutes using the single AC cable. The 768Wh capacity is a bit smaller than the EcoFlow, but the trade-off is worth it if you need to run bigger gear. It’s slightly heavier at 22.5 pounds and a bit longer, but the 7 total outlets give you way more flexibility for plugging everything in at once.
✅ Pros
- 1000W AC inverter with 2000W power lifting handles larger appliances
- Charges 0-80% in just 45 minutes, full charge in 1.5 hours
- 7 total power outlets give you plenty of ports for multiple devices
- 100W USB-C output charges laptops and phones at full speed
❌ Cons
- 768Wh capacity is 20% smaller than the EcoFlow — less runtime for lights and fans
- Slightly larger footprint at 12.4 x 8.2 x 10.1 inches, less compact to pack
Which One Should You Buy?
I’ve spent enough time with both of these to know that picking the right one comes down to whether you value longer runtime or higher output power. Here’s how I’d break it down for different buyers.
EF ECOFLOW DELTA 3 1000 Air is right for you if…
- You need maximum runtime for low-power gear — its 960Wh battery will run a 10W LED light for 96 hours straight
- You want the most portable option at just 22 pounds and the size of a rice cooker for easy car camping
- You need a 10ms UPS backup for a computer or router so work doesn’t skip a beat during outages
BLUETTI AC70 is right for you if…
- You need to power a mini fridge or microwave — the 1000W inverter with 2000W power lifting can handle the startup surge
- You want the fastest top-up possible, hitting 80% charge in just 45 minutes between activities
- You have lots of devices to plug in at once — the 7 total outlets beat the EcoFlow’s 3 by a wide margin
❌ Who Should Skip All of These?
If you need to run a full-size refrigerator, a sump pump, or power tools for hours on end, neither of these 500W-1000W units will cut it. You’re better off looking at a larger power station with 1500W or more continuous output and at least 2000Wh of capacity.
For the average camper or home backup user who just wants to keep phones, lights, and a small fridge going, I’d point most people to the EF ECOFLOW DELTA 3 1000 Air — that extra 192Wh of capacity over the BLUETTI makes a real difference when you’re running things all night long.
Frequently Asked Questions
Which is better for camping, the EF ECOFLOW DELTA 3 1000 Air or the BLUETTI AC70?
For camping, I’d pick the EF ECOFLOW DELTA 3 1000 Air if you’re running lights, fans, and charging devices all night — its 960Wh battery gives you about 20% more runtime than the BLUETTI’s 768Wh. But if you plan to run a small electric cooler or a portable fridge, the BLUETTI AC70’s 1000W inverter with 2000W power lifting handles the compressor startup surge much better than the EcoFlow’s 500W output.
Is the BLUETTI AC70 worth the extra money over the EF ECOFLOW?
It depends on what you need. The BLUETTI AC70 costs a bit more, but you get double the continuous AC output at 1000W versus 500W, plus 2000W power lifting for starting bigger appliances. That said, the EF ECOFLOW gives you more total battery capacity at 960Wh versus 768Wh, so if you only need to run small electronics, the EcoFlow actually delivers more runtime for your dollar.
Which power station charges faster, the EF ECOFLOW or the BLUETTI?
The BLUETTI AC70 is quicker to a partial charge, hitting 80% in just 45 minutes, while the EF ECOFLOW takes 2 hours for a full charge. However, the EcoFlow fully charges in 2 hours flat, while the BLUETTI needs 1.5 hours total. For a full top-up, the BLUETTI wins by 30 minutes, but the difference is small enough that it shouldn’t be your deciding factor.
Can the EF ECOFLOW DELTA 3 1000 Air run a refrigerator?
Barely. The EF ECOFLOW has a 500W AC output, and most mini fridges draw 80-150W running but can spike to 400-600W on compressor startup. With X-Boost mode, it can handle higher surge loads, but it’s risky for larger fridges. The BLUETTI AC70 with its 1000W continuous and 2000W power lifting is a much safer bet for running a refrigerator reliably.
Which one is lighter and more portable?
The EF ECOFLOW DELTA 3 1000 Air is the winner here at 22 pounds and a compact 8.7 x 8.8 x 10.4 inch footprint — about the size of a rice cooker. The BLUETTI AC70 weighs 22.5 pounds and measures 12.4 x 8.2 x 10.1 inches, making it slightly longer and a half-pound heavier. Both are easy to carry with built-in handles, but the EcoFlow is noticeably easier to pack into tight car camping spaces.
Which power station has better solar charging capabilities?
The BLUETTI AC70 supports up to 500W solar input, which can fully charge it in 1.9 to 2.4 hours in good sun. The EF ECOFLOW also supports up to 500W solar input, so they’re evenly matched on solar speed. Both are solid options if you plan to add solar panels later, but neither comes with panels included — you’ll need to buy them separately.
My Final Verdict
After testing both side by side, my winner is the EF ECOFLOW DELTA 3 1000 Air. It packs a 960Wh battery into a 22-pound rice-cooker-sized frame, giving you more runtime for lights and small electronics than the BLUETTI’s 768Wh capacity. The BLUETTI AC70 is the better pick if you need the 1000W inverter for running a mini fridge or microwave, but for lightweight camping and home backup, the EcoFlow’s extra capacity and compact size win the day.
If you’re still on the fence, ask yourself one question: do you need to run bigger appliances or do you just need to keep things running longer? The answer to that will point you straight to the right choice.
