The EcoFlow DELTA 3 Classic is a power station with a lithium iron phosphate battery, three AC outlets and enough power to run several home appliances together: router, lights, a small fridge. When the power goes out it switches to the battery in ten milliseconds, and connected appliances don't notice.
It charges from the outlet in about an hour, or from the sun with a small panel. From the car it only charges: it has no twelve-volt outlet on the output side, so portable fridges and camper accessories need an adapter. The two USB-C ports charge a laptop and a phone together, with no separate chargers needed.
It's a first battery for anyone who wants to cover a short blackout or bring power along for a weekend. Anyone who needs to start a heavy appliance, or stay several days off the grid, needs more capacity and more power.

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.
