Best power station for

Home backup

Keep the fridge, Wi-Fi, lights and medical devices running through a blackout.

⚡ ~3,000 Wh/day 🔋 2,000 Wh+ 🔌 1,800W+ output

For power outages, capacity and output are king. You want enough storage to ride out a multi-hour (or multi-day) outage running a full-size fridge, Wi-Fi, phones, lights and any medical devices — plus enough continuous output to actually start that fridge compressor. Expandable units shine here: add batteries to cover longer outages.

Frequently asked

What size power station runs a fridge during an outage? +

A full-size fridge uses roughly 1–2 kWh per day. A 2,000 Wh station keeps it (plus phones and Wi-Fi) going about a day; 3,000–6,000 Wh or an expandable system covers multi-day outages.

Do I need an expandable system for home backup? +

If outages in your area last more than a day, yes. Expandable units let you stack extra batteries to reach whole-day or multi-day autonomy.
