The BLUETTI Elite 400 is a lithium iron phosphate power station designed to stay connected to the home grid, not for travel: when power fails it switches to the battery so fast that a computer left on doesn't notice, and whatever is plugged into its outlets doesn't shut down. The buttons on the panel are enough to set it up, and the app is for finer adjustments, like automatic shutoff thresholds.
It has wheels and a telescopic handle, and moves like a trolley case: almost forty kilos cross a garage or a hallway without needing to be lifted. Charging from the outlet is fast in the most aggressive mode, and the dedicated solar input accepts panels with MC4 connectors, in series or in parallel, to keep it charged even away from an outlet.
It's the storage unit for anyone who wants a reserve that stays put in one place — near the fridge, in the garage, in a utility room — plugged in and forgotten until it's needed. Anyone looking for something to load into a car every weekend should look at a different size.

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.
