Best portable power stations with 3,500W AC output

Top pick: EcoFlow Delta Pro 3 — it's the one that comfortably clears the 3,500W bar (4,000W continuous), with a big 4,096Wh battery and a 10ms UPS switchover, so it can carry a fridge, well pump or a few circuits through an outage. It's heavy, so treat it as a home-backup unit rather than something you carry to a campsite.

• Pecron F3000LFP — rated 3,600W with 4,500W peak in a lighter ~63 lb body; the better choice if you need to move it around.
• Pecron E3600LFP — LiFePO4, ~79 lb, strong owner ratings; a solid mid-weight alternative.
• Aferiy P310 — the most capacity for the money and expandable, but check its AC rating before buying.
• BLUETTI Apex 300 — best if you want a modular system you can grow later.
• Jackery HomePower 3600 Plus — simplest all-in-one solar bundle for a cabin or shed.

Note: the Delta Pro 3 and Apex 300 are the only ones here whose AC output is stated clearly at or above 3,500W; for the others, confirm the continuous rating on the listing.
