The BLUETTI AC240P is a portable lithium iron phosphate battery storage unit designed to stay outdoors: its resistance to rain and dust makes it suited to a job site, a boat, a storage room with no door. It has four AC outlets, and its starting capacity covers a day of work away from the grid.
It grows by adding batteries from its family, up to more than five times the capacity it starts with: it's the same machine that in its second year covers far more than it did in its first. Connected to a home outlet it acts as a reserve, and when the grid drops, it takes the place of power before a work session is lost. A motor's startup surge needs a separate function to switch on, which briefly raises the power ceiling.
From the outlet it recovers most of its charge in three quarters of an hour; from the sun it needs a clear day and real panels. At thirty-three kilos with the handle it can be moved but not carried around: it's a block to put in one place and leave, and the more batteries added alongside it, the more that place needs planning in advance.

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.
