The short answer: the BLUETTI AC70P is the lighter, cheaper-to-run option for phones, laptops, lights and small camp gear, while the BLUETTI AC180P carries enough capacity and output to run a fridge, a kettle or part of a house during an outage. Both use LiFePO4 batteries and both charge 0 to 80 percent in about 45 minutes on Turbo Charging, so the real decision comes down to how much Wh you'll get through in a day and how many watts your gear actually pulls.
| What you need | What to look at |
|---|---|
| Lightweight power for phones, a laptop, LED lights and camera batteries on weekend trips | AC70P, 864Wh and 10.7kg to carry |
| Running a fridge, kettle or microwave, or backing up part of the house in a blackout | AC180P, 1,440Wh and 1,800W continuous |

Estimates only. Capacity allows 20% for inverter losses and battery you shouldn't use. Fridge watts are while the compressor runs, and hours are how long it runs in a day, which climbs in hot weather. Check the manufacturer's specs before you buy.
Side by side specs
Both stations share a LiFePO4 battery, Bluetooth app control, a 15W wireless charging pad and a 5 year warranty. The differences that matter are capacity, continuous output and the weight that comes with the bigger battery.
| Spec | AC70P | AC180P |
|---|---|---|
| Battery capacity | 864Wh LiFePO4 | 1,440Wh LiFePO4 |
| Continuous AC output | 1,000W | 1,800W |
| Power Lifting Mode | up to 2,000W (resistive loads only) | up to 2,700W (resistive loads only) |
| AC charging, Turbo | up to 850W, 0 to 80% in about 45 minutes | up to 1,440W, 0 to 80% in about 45 minutes |
| Solar input | up to 500W | up to 500W |
| DC output | 1 x 12V/10A car outlet | 1 x 12V/10A car outlet |

What the extra capacity actually runs
A camp fridge, worked out
Take a 40L compressor fridge that draws about 45W when the compressor is running, cycling for roughly 12 hours of a 24 hour day in warm weather. That's 45W x 12h, or 540Wh a day. Running it from the 12V DC outlet skips inverter losses altogether, but you should still allow around 10 percent for usable capacity and standby drain on the battery itself.
| Appliance | Draw | Run time | Energy used |
|---|---|---|---|
| Compressor fridge | 45W when running | 12h compressor run time in 24h | 540Wh per day |
The AC70P's 864Wh gives you about 778Wh of usable capacity after that 10 percent allowance, which covers roughly one day of fridge running before you're looking for a recharge. The AC180P's 1,440Wh gives about 1,296Wh usable, good for about two days on the same fridge. Neither figure accounts for lights, charging phones or anything else drawing from the same battery, so treat these as a baseline and add your other loads on top. For a longer walkthrough of this kind of sum, our guide on working out runtime from amp hours covers the same method for other devices.
Everyday electronics
If a fridge isn't in the picture and you're mostly charging phones, running a laptop of an evening and keeping a couple of LED lights going, the AC70P's 864Wh comfortably covers a weekend without a recharge. The AC180P does the same job for longer between charges, but you're carrying an extra 5.3kg of battery you may not need.
What the extra output actually runs
Capacity tells you how long something runs. Output tells you what you can switch on at all. This is where the two units split clearly.
The AC70P's 1,000W continuous rating covers most camp electronics, lighting and charging, but it won't run an electric kettle or a microwave at the same time as anything else drawing real power. Its Power Lifting Mode pushes output to 2,000W by lowering voltage for resistive heating loads, kettles, hair dryers, small heaters, so a typical 1,800 to 2,000W kettle can still boil water on the AC70P through that mode. Power Lifting Mode is not extra continuous capacity and it isn't suited to motors, compressors or electronics, so don't run a fridge compressor or a power tool through it.
The AC180P's 1,800W continuous rating runs that same kettle without needing Power Lifting Mode at all, and its 2,700W lifting headroom is there for something heavier again. It also has the output to run a fridge and a 1,200W inverter microwave at once, a combined draw of 45W plus 1,200W, or 1,245W, which sits comfortably under the AC180P's 1,800W ceiling but would overload the AC70P's 1,000W rating.
Weight and size
At 10.7kg the AC70P is a one-handed lift in and out of a ute tray or camper boot, and its 314 x 210 x 256mm footprint fits a cupboard or under-seat storage without much planning. The AC180P weighs 16kg and measures 340 x 247 x 317mm, still carryable with one hand on the built-in handle but noticeably more of a lump to wedge into a packed 4WD or shift up onto a bench during setup. If you're loading and unloading daily on a long touring trip, that 5.3kg difference adds up by the end of the week.
Charging on the road
Both units reach 80 percent from flat in about 45 minutes on AC Turbo Charging, the AC70P pulling up to 850W from the wall and the AC180P pulling up to 1,440W. Both accept up to 500W of solar input through MC4 connectors, so a folding solar blanket works with either. Because the AC180P holds more energy for the same 500W panel, expect it to take proportionally longer to top up from solar than the smaller AC70P on the same panel, even though both will fill in a few hours of decent midday sun. If you're setting up for extended time off mains power, our piece on going off the grid covers panel sizing and placement in more detail.
Who each suits
The AC70P suits weekend campers, hikers basing out of a car, and anyone who wants backup power for phones, torches, a CPAP on DC, or a laptop without adding much weight to the kit. It's also a sensible choice as a second unit paired with a bigger station, or as the only power source for someone who doesn't run a fridge off-grid.
The AC180P suits caravanners and 4WD tourers running a camp fridge for days at a stretch, anyone who wants to boil a kettle or run a microwave without planning around Power Lifting Mode, and households wanting backup for a few circuits during a blackout. The extra 5.3kg is the trade-off for genuinely useful headroom.

Both units sit within our Portable Power range alongside the rest of the lineup if neither is quite the fit.
Frequently asked questions
Can the AC70P run a fridge all weekend?
Based on a fridge drawing 45W when running and cycling for about 12 hours a day, the AC70P's 864Wh gives you roughly one day of fridge running once you allow for usable capacity. For a full weekend you'd want to pair it with solar input or step up to the AC180P.
What is Power Lifting Mode and can I use it for a kettle?
Power Lifting Mode lowers the inverter's output voltage to let resistive heating appliances like kettles, hair dryers and small heaters draw above the unit's rated continuous output. It is not extra continuous capacity and it isn't suited to motors, compressors or electronics, so check your appliance type before relying on it.
Do both charge the same way?
Both reach 80 percent in about 45 minutes on AC Turbo Charging and both accept up to 500W of solar, but the AC70P draws up to 850W from the wall and the AC180P up to 1,440W to hit that time with its larger battery.
Which one is better for a home blackout?
The AC180P's 1,800W continuous output and 1,440Wh capacity give you more to work with for fridges, lighting circuits or a CPAP overnight. The AC70P still covers phones, lighting and small electronics if that's all you need backed up.
