EcoFlow DELTA Pro is a portable lithium iron phosphate storage unit that lives at home or follows a job site: it has wheels and an extendable handle, because forty-five kilos don't lift by hand. Plugged into the outlet it acts as a fixed reserve, and with two external batteries, sold separately, capacity rises when needed.
The output peak is double the continuous power, and that's what decides whether a fridge's compressor or a circular saw actually start instead of tripping the protection. When the grid drops, the switch to the battery is fast enough that a running computer doesn't turn off.
It charges from the outlet, the sun or the car, and outdoors the panels are enough to keep it working away from the grid. It's the unit for anyone who has to power real appliances: at home during a long outage, or where the grid doesn't reach at all.

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.
