How many watt-hours do I actually need?

For an apartment, 300–500 Wh covers phones, laptop, router and a small light for ~24h. A house with a fridge needs 1000–1500 Wh or more once you account for compressor cycling.

Lithium-ion (NMC) vs LiFePO4?

LiFePO4 (LFP) lasts 3,000–6,000 cycles vs 500–1,500 for NMC, handles heat better, and is safer. It costs more up-front but wins past year 2 of real use.

Can a power station replace a gas generator?

For 24–48h events, yes — plus it is silent, indoor-safe and needs zero fuel storage. For multi-day events you still want a gas generator OR a solar panel + expansion battery.

Does it run a CPAP overnight?

Most CPAPs draw 30–60W without the humidifier. A 500Wh station runs one for ~8 nights. Turn the humidifier off to double runtime.

Blackout & Power

Portable Power Stations for Emergencies

Pick by real use, not marketing. We break these down by household shape — apartment, house, CPAP or medical device, and whole-home backup — because the right station is different for each.

Apartment / Small Space

300–500 Wh — phones, laptop, router, small light

Apartments rarely need to power a fridge — the building generator or timing of outages handles it. Prioritize a station you can store in a closet and top-off from a wall outlet in 1–2 hours.

Recommended minimum: 300 Wh

House / Family

1000–1500 Wh — fridge cycling, fans, devices, small appliances

A house-sized station plus a 100W solar panel covers 24–36h of food-preservation and communications during a blackout. Look for LiFePO4 (LFP) chemistry for 3,000+ cycle life.

Recommended minimum: 1000 Wh

CPAP / Medical Devices

500–1000 Wh — quiet runtime for overnight use

Most CPAPs draw 30–60W without humidifier (double with). A 500Wh station runs a CPAP ~8 nights without recharge when the humidifier is off. Confirm your machine accepts DC if you want to skip the inverter loss.

Recommended minimum: 500 Wh

Whole-Home Backup

2000 Wh+ with expansion — fridge, furnace fan, devices

Only consider this tier if you have a modular station (EcoFlow DELTA, Jackery 2000 Plus, Bluetti AC) that accepts battery expansion. Pair with 200–400W of solar for true multi-day resilience.

Recommended minimum: 2000 Wh

Already own a station? Plan the refills.

Expansion batteries, solar panels, CO alarms, and backup cables are the difference between a station that works once and a system that keeps working.
