The Short AnswerA typical full-size refrigerator runs 10 to 14 hours on a 2000Wh power station, or 5 to 7 hours on a 1000Wh unit. The exact number depends on your fridge's efficiency, the ambient temperature, and how often the door opens. Here's how to calculate it precisely for your situation — and how to run a fridge for days, not hours.How to Calculate Fridge RuntimeRefrigerators cycle on and off, so they don't draw their full wattage continuously. A modern full-size fridge uses roughly 100–200 watts while the compressor runs, averaging about 1–2 kWh per day in real use. To...

How to Size a Portable Power Station the Right WayThe most common mistake buyers make is guessing. Buy too small and your power station dies mid-outage; buy too big and you've overspent by hundreds. Sizing a portable power station comes down to two numbers: the watts your devices draw (can the station run them at all?) and the watt-hours of capacity (how long will it last?). Here's how to get both right.Step 1: Add Up Your Running WattsList every device you need to power at the same time and add up their wattage. Rough draws: LED lights 10W each, phone...

EcoFlow vs Bluetti: The Head-to-HeadEcoFlow and Bluetti are the two most capable portable power station brands in 2026 — both offer LFP battery chemistry, fast charging, and expandable capacity. The differences come down to charging speed, ecosystem depth, and specific model features. Here's how they stack up.Battery Chemistry: A TieBoth EcoFlow's DELTA 3 series and Bluetti's AC series use LFP (lithium iron phosphate) chemistry rated for 3,000+ cycles. Both significantly outperform NMC alternatives like older Jackery models. On battery longevity, this is a genuine tie.Charging Speed: EcoFlow WinsEcoFlow's X-Stream technology charges the DELTA 3 Plus from 0 to 80% in...

What to Look for in a Home Backup Power StationA portable power station for home backup needs three things: enough capacity to run your essentials, enough output wattage to handle startup surges, and fast enough recharging to stay ready between storms. Here's how to think about each.How Much Capacity Do You Need?Add up the wattage of everything you need to run and multiply by hours. A practical 12-hour emergency checklist: Refrigerator (150–200W) × 8 hours → 1,200–1,600Wh CPAP machine (50W) × 8 hours → 400Wh LED lights + router (50W) × 12 hours → 600Wh Phone and laptop charging (100W)...
