What this station is
The Anker SOLIX C800 Plus stores 768 Wh of energy, as announced by the brand. Its outlets can give up to 1,200 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 10.9 kg, you carry it with one hand for a short walk, like a full shopping bag.
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 Anker SOLIX C800 Plus covers about 1.1 days of that.
Add an average fridge (45 W on average) and the Anker SOLIX C800 Plus keeps it going for about 12 h on its own, or 9.3 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 300 W of solar panels. Even in full sun, a full charge takes at least 2.6 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 Anker SOLIX C800 Plus cover?
About 1.1 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 Anker SOLIX C800 Plus run a fridge?
About 12 h for an average fridge (45 W on average), or 9.3 h if you also keep the router, two lamps and a phone going. A big or old fridge uses more.
Can the Anker SOLIX C800 Plus 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 3.7 nights. The heated humidifier uses much more: turn it off, or use the 12 V cable sold by the CPAP maker.
