The BLUETTI AC240 is a portable lithium iron phosphate battery storage unit that starts small and grows: on its own it covers an evening of work or a night of lights and a fridge, and with satellite batteries it reaches a home-sized capacity without the main unit changing. It has four AC outlets, and its resistance to rain and dust lets it be left where there's no roof: a boat, a job site, an open lean-to.
Connected to the grid it acts as a reserve, and when power fails it takes over without the computer restarting. The four outlets, though, share the same power and don't each have their own: two heavy loads together trip the protection. For starting a compressor or a pump, which for an instant draw much more than they consume afterward, there's a separate function to switch on that raises the ceiling.
It charges from the outlet or the sun, and from the grid a full charge takes about as long as an errand. Thirty-three kilos are moved with the handle but not carried on a shoulder: its place is the garage, the equipped van, the corner near the electrical panel. It suits anyone who wants to start small and expand when capacity gets tight, not anyone looking for something to load into the car every weekend.

The rest of the data comes from one page on the manufacturer's site, cited row by row in the table above.
A manual or a datasheet counts as a source even when the original file is hosted elsewhere: what matters is the document, not the server. Where that happens, it is stated above.
These numbers are calculated, not stated: they have no source to cite, they have a formula you can redo. The price used is the manufacturer's list price, which is stable and the same in every country — not a shop's price on the day.
Chosen by the declared use tier and footprint, not by price: we don't publish prices.
