EcoFlow DELTA 2 Max is a lithium iron phosphate power station built to grow: start with the unit alone and reach triple the capacity by adding two external batteries, sold separately, without changing anything already in place.
Plugged into the outlet it acts as backup, and when the light goes out the connected appliances don't turn off. On the panel there are four outlets and two generous USB-C ports, so a phone and a laptop charge without hunting for a separate charger. It accepts two solar inputs together: with the panels open, it fills up while you use it.
Twenty-three kilos take it out of the category of things you move every day: it sits in one spot and works from there, at home or in the garage. It's the choice for anyone who wants to start with a mid-size unit and expand it over time, instead of buying everything again once the capacity starts to feel tight.

The rest of the data comes from 2 pages 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.
