Our take
Its value drops quickly if the buyer expects one box to cover every emergency load.
Why it made the shortlist
256Wh moves it into a more useful weekend and short-outage tier, especially when the buyer can recharge daily or keep the load list narrow. For jackery explorer 240 portable power station, the useful comparison is how the product behaves in the buyer's actual routine rather than how large the headline numbers look. Its best use is a planned low-draw kit where the buyer knows which devices matter first.
Keep it for a short, named device list and move up a tier if the plan includes motors, heat, or unattended overnight runtime.
