Power station comparisonsWhich one
should you buy?

Start from the capacity you need. Under 700 Wh covers phones, laptops, a CPAP overnight and a weekend of camping lights. Around 1 kWh runs a full-size fridge for most of a day. Around 2 kWh carries a fridge, a router, lights and a few chargers through a night-long outage. From 3 kWh up you are shopping for home backup, often with 240 V output and a transfer switch. The filters below group every duel by these sizes, so you compare rivals that play in the same league.

Then look at the three gaps that decide most duels. Continuous and surge output, because that is what starts a well pump or a space heater. Solar and wall charging speed, because a station that refills in an hour is a different tool from one that takes four. And expansion, because a model that accepts extra batteries can grow with you while a sealed one cannot. Weight, port layout and UPS switchover time settle the rest.

Upgrade duels are a separate question. When a brand retires a model, the older unit often stays on sale at a discount for months. Our Should you upgrade? pages weigh that discount against what the successor adds, so an owner knows whether to switch and a shopper knows whether the older unit is still the better buy.

Across brands, the four line-ups overlap more than their marketing suggests. EcoFlow, Anker SOLIX, BLUETTI and Jackery all build their current stations on LiFePO4 cells rated for thousands of cycles. The real differences are in app features, fast-charging behavior, warranty length and how each brand prices its expansion batteries. Every brand vs brand duel spells those out for one specific pair, with the price gap of the day.
