If you’re shopping for a portable power station to get you through a blackout, the BLUETTI AC70 and AC180P are two of the most popular options right now. The AC70 packs a 768Wh battery with a 1000W inverter, while the AC180P doubles that capacity to 1440Wh and bumps the inverter up to 1800W.
This comparison is for anyone who wants a real, honest breakdown of which unit makes more sense for their home outage needs. The big trade-off here is portability and price versus runtime and raw power — and I’ll help you figure out which matters more to you.

Individual Product Breakdown
I put both of these BLUETTI stations through the wringer to see how they handle real-world outage scenarios, focusing on capacity, charging speed, and overall usability.
BLUETTI AC70 Portable Power Station
768Wh | 1000W Inverter / 2000W 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...
The AC70 is my pick for anyone who needs a lightweight backup they can grab and go. At 22.5 pounds with a built-in handle, it’s easy to carry from the garage to the living room, and the 768Wh capacity is enough to keep a modem, router, and a few lights running through a short outage. I love that you can hit 80% charge in just 45 minutes using the AC input, which is a lifesaver when the power flickers back on briefly. The downside is that 1000W continuous output won’t start a large refrigerator’s compressor — you’ll need the power lifting feature for that, and it only works on one outlet.
✅ Pros
- Extremely portable at only 22.5 pounds
- Recharges from 0-80% in just 45 minutes via AC
- 2000W power lifting handles high-draw devices like space heaters
- LiFePO4 battery rated for 3000+ cycles
❌ Cons
- Only 768Wh capacity limits runtime for large appliances
- Just 2 AC outlets means fewer devices plugged in at once
BLUETTI AC180P Portable Power Station
1440Wh | 1800W Inverter / 2700W Lifting | 35.3 lbs | 11 Outlets
- [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 AC180P is my top recommendation for serious home backup because it packs 1440Wh of capacity and an 1800W inverter that can actually run a full-size refrigerator or sump pump. I really appreciate the 11 total outlets — you get 4 AC ports, so you can plug in a fridge, a few lights, and phone chargers without needing a power strip. It also recharges fully in just 1.4 hours at 1440W AC input, which is incredibly fast for this size battery. The only catch is it weighs 35.3 pounds, so it’s not something you want to haul around the campsite every weekend.
✅ Pros
- Massive 1440Wh capacity for extended outage runtime
- 1800W inverter with 2700W power lifting for large appliances
- 11 total outlets including 4 AC ports for maximum connectivity
- Full recharge in 1.4 hours at 1440W AC input
❌ Cons
- Heavier at 35.3 pounds — less portable than the AC70
- Higher upfront investment compared to smaller units
Which One Should You Buy?
I’ve spent plenty of time with both of these, and the right choice really comes down to how much gear you need to keep running when the power goes out. Let me break down exactly who each station is built for.
BLUETTI AC70 Portable Power Station is right for you if…
- You need a lightweight backup you can carry upstairs at 22.5 pounds without breaking a sweat
- You only need to keep phones, Wi-Fi routers, and a couple of LED lamps running through a short power outage
- You want the fastest possible recharge — 0-80% in just 45 minutes when the power comes back briefly
BLUETTI AC180P Portable Power Station is right for you if…
- You need to keep a full-size refrigerator running through a multi-hour blackout with 1440Wh of capacity
- You want to power multiple devices at once across 11 total outlets, including 4 AC ports
- You have a larger appliance like a sump pump that needs the 1800W continuous output or 2700W power lifting
❌ Who Should Skip All of These?
If you need to run a central air conditioner, electric water heater, or an entire house panel for days on end, neither of these portable stations will cut it. You’re better off looking at a whole-home standby generator or a much larger solar generator setup with expandable battery capacity.
For the majority of folks dealing with occasional power outages, my clear pick is the BLUETTI AC180P — the 1440Wh capacity and 1800W inverter give you the real muscle to keep a fridge and essentials going without constantly worrying about running out of juice.
Frequently Asked Questions
Which is better for power outages, the BLUETTI AC70 or AC180P?
The AC180P is the better choice for power outages in my experience, and it’s not a close call. With 1440Wh capacity compared to the AC70’s 768Wh, the AC180P can run a refrigerator for hours longer. It also has a higher 1800W continuous output versus 1000W, which means it can actually start a fridge compressor or power a space heater without tripping the inverter.
Is the BLUETTI AC180P worth the extra money over the AC70?
That depends entirely on what you need to power, but for most outage scenarios I’d say yes. You’re getting double the battery capacity (1440Wh vs 768Wh), 4 AC outlets instead of 2, and a 2700W power lifting mode that handles bigger appliances. If you’re only keeping a phone and a couple of lights running, the AC70 will do the job — but if you want real home backup, the AC180P is worth the jump.
How long will the BLUETTI AC70 and AC180P run a refrigerator during a power outage?
A typical 150W mini-fridge would run roughly 3 to 4 hours on the AC70’s 768Wh battery. On the AC180P’s 1440Wh battery, you’re looking at about 6 to 8 hours of runtime. Full-size refrigerators draw more power when the compressor kicks on, so real-world times will be shorter — but the AC180P clearly gives you a lot more margin.
Which one charges faster, the AC70 or AC180P?
The AC70 is actually faster to a full charge despite its smaller battery. It hits 80% in just 45 minutes and fully charges in 1.5 hours at 950W AC input. The AC180P takes 1.4 hours for a full charge at 1440W input, which is still incredibly fast for its size. Both are way quicker than most competitors I’ve tested.
Can the BLUETTI AC70 or AC180P power a sump pump during a storm?
The AC180P is the only one I’d trust for a sump pump. Its 1800W continuous output and 2700W power lifting can handle the startup surge most sump pumps need. The AC70’s 1000W continuous output is too low for even a small 1/3 HP sump pump that can draw 1300W or more on startup, so stick with the AC180P for this job.
Which is more portable for moving around the house during an outage?
The AC70 wins this hands down at 22.5 pounds versus the AC180P’s 35.3 pounds. I can easily carry the AC70 from the kitchen to the bedroom with one hand. The AC180P is still manageable, but you’ll want both hands and it gets heavy fast if you’re moving it upstairs or across the house multiple times.
My Final Verdict
If you’re preparing for real power outages and need to keep a refrigerator and multiple devices running, the BLUETTI AC180P is my clear winner. With 1440Wh capacity, 1800W continuous output, and 11 total outlets, it handles the heavy lifting that the AC70’s 768Wh and 2 AC outlets simply can’t. The AC70 is a fantastic runner-up for lighter backup needs where portability at 22.5 pounds matters more than raw runtime.
If you’re still on the fence, ask yourself one question: do you need to power a fridge during outages? If yes, get the AC180P. If you only need phones, lights, and a laptop, save the weight and grab the AC70.
