Jackery Explorer 3000 v2 is a power station with lithium iron phosphate cells built to keep several home appliances running together, not a laptop and a lamp. There are three AC outlets, so one doesn't have to be unplugged to start another. Capacity, though, is fixed: no batteries added later.
It charges from the grid, the sun or the car outlet. For the sun it has two separate inputs, and each accepts two panels: anyone connecting four fills up while working, without touching anything. When power fails it steps in on its own, fast enough that a running computer doesn't turn off.
It moves, but isn't carried: its home is a corner of the garage, the job site or the van. At low load it's quiet, and that matters for anyone leaving it on in a bedroom overnight. It suits anyone who wants a fixed home reserve for the unexpected, or for working outdoors with several appliances running together.
Best balance of technical score and price among the 3 sheets in the Home backup category (flat-sized tier): list price €1481, technical score 50/100.

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.
