Portable Power Stations for Home Backup

How to size a portable power station for a home outage using essential loads, runtime, and startup surge.

Start with the load, not the product

Home backup is not about powering everything. It is about keeping a short list of essential devices running for a known number of hours.

List essentials

Choose the refrigerator, router, lights, phone charging, and any medical device you actually need.

Measure hours

Eight hours is a useful starting point; longer outages need more capacity or a recharge plan.

Check surge

Compressors and pumps can draw several times their running watts for a moment.

Planning starting point: about 2,800Wh before reserve. Add 20–30% for battery aging, cold temperatures, and devices you forgot.

Common questions

What size do I need for a fridge?

A 1,000–2,000Wh station is a common starting range, but duty cycle and startup surge matter.

Can I run a space heater?

Technically some stations can, but runtime is usually short and the load is inefficient.

Can I recharge during an outage?

Only with a planned solar setup or another power source; do not assume the grid will return quickly.
