What this station is
The BLUETTI AC180 stores 1,152 Wh of energy, as announced by the brand. Its outlets can give up to 1,800 W at the same time: add up the watts of everything you plug in and stay under that number. It is a mid-size station: enough for a router, lights and phones over a day or more, and a fridge for some hours.
Its battery is LFP (lithium iron phosphate). This type usually keeps most of its capacity after thousands of charges, so it suits a station you use often. At 16 kg, plan two hands or a trolley. Choose where it lives before an outage.
During a power cut
A simple day without power: the internet router on for 24 hours, two LED lamps for 6 hours, a phone charging for 3 hours, and the station itself switched on. That comes to 606 Wh per day. The BLUETTI AC180 covers about 1.6 days of that.
Add an average fridge (45 W on average) and the BLUETTI AC180 keeps it going for about 18 h on its own, or 14 h with the basic needs above on top.
The brand announces a switch-over time of 20 ms: if mains power drops, devices plugged into it keep running. Useful for a router or a computer.
Charging it
It accepts up to 500 W of solar panels. Even in full sun, a full charge takes at least 2.3 h. In practice panels give less than their rated watts, so count on longer, often a few days in winter.
Questions about this station
How many days of power cut does the BLUETTI AC180 cover?
About 1.6 days for the basics: router, two LED lamps, a phone and the station itself, 606 Wh per day. Each extra device shortens that time. Try your own list in the calculator.
How long can the BLUETTI AC180 run a fridge?
About 18 h for an average fridge (45 W on average), or 14 h if you also keep the router, two lamps and a phone going. A big or old fridge uses more.
Can the BLUETTI AC180 run a CPAP machine all night?
Yes. A CPAP without heated humidifier uses about 12 W. Over 8 hours, with the station itself switched on, that is 176 Wh per night, so about 5.6 nights. The heated humidifier uses much more: turn it off, or use the 12 V cable sold by the CPAP maker.
