An apartment rules out the usual answer: a generator needs ventilation you do not have and a permit you will not get. What is left has to be safe to store in a closet, light enough to carry up a stairwell, and in 2026 still hold the fridge, the router, and a laptop.

Apartments remove the default answer before the shopping starts. A generator needs ventilation a flat does not have and permission a lease will not give, so the alternatives are a battery or nothing. That changes which specifications matter: the unit is stored in a hallway cupboard rather than a garage, carried up a stairwell with the lift out, and charged in a room where people sleep.
Shopping the same lists as a homeowner. The capacity that suits a house is regularly a two-person lift, which is a real problem on the fourth floor during the outage you bought it for. The subtler mistake is skipping chemistry: nickel-based packs are perfectly safe in a ventilated garage and are the wrong trade indoors, where thermal tolerance is worth more than the weight it saves.
This is a short list by construction, and its shortness is the finding rather than a gap in our coverage — very few products clear a refrigerator and still meet both constraints. The weight ceiling is a published threshold rather than a measured ergonomic limit, and it assumes one able adult and a staircase, which will not describe every reader.
13 of 80 tracked stations meet this list's eligibility rule, and the 10 highest-scoring of them are ranked above. The highest-scoring stations the rule excludes are EcoFlow DELTA Pro Ultra X, EcoFlow DELTA Pro 3 and EcoFlow DELTA 3 Plus. They rank well elsewhere on the site; they do not answer this question.
