For a furnace blower, the EcoFlow DELTA 3 Plus has the output and add-on batteries. For longer outages, the Jackery Explorer 2000 v2 doubles the capacity. For a fridge and essentials, the Jackery Explorer 1000 v2 is plenty, and for phones, lights and a CPAP the RIVER 3 Plus or BLUETTI Elite 30 V2 cost far less.

The right size depends on what you’re trying to keep running:
| Goal | Output needed | Capacity to aim for |
|---|---|---|
| Phones, lights, router | 300 W+ | 250–500 Wh |
| Add a CPAP overnight | 300 W+ | 300–500 Wh |
| Add a fridge | 1,000 W+ | 1,000 Wh+ |
| Add a furnace blower | 1,500 W+ | 1,000 Wh+, expandable ideal |
These are starting points. Your actual needs depend on your appliances — the winter runtime calculator will give you a better estimate in two minutes.
Plan where it will live. In winter, a power station belongs in the heated part of your home. Most won’t charge below 0°C and some stop working around −10°C. Check each model in the cold-weather spec database.
Plan how the furnace connects. Most furnaces are hard-wired and need a transfer switch or inlet installed by an electrician before a power station can run them. Read our guide to running a furnace on a power station.
Best for: Home backup and cabins that need to run bigger loads
Cold limits not published
High output, fast UPS switchover and expandable capacity make it the most flexible pick for winter outages.
Best for: Longer outages with a furnace blower and fridge
Keep it indoors below freezing
About twice the capacity of the Explorer 1000 v2 with 2,200 W output; same published −10°C operating floor, and not expandable.
Best for: Grab-and-go backup and three-season camping
Keep it indoors below freezing
Lighter than rivals at this capacity, with clearly published cold-weather limits — a rare plus.
Best for: Phones, lights, internet and a CPAP — with room to expand
Keep it indoors below freezing
A small LiFePO4 unit rated to run down to −10°C, with a sub-10 ms UPS switchover and an add-on battery option.
Best for: Keeping phones, lights and a CPAP going on a budget
Cold limits not published
Small and cheap — fine for small electronics, not for heaters or a furnace.
For phones, lights and internet, 250–500 Wh is often enough for a night. For a fridge, aim for 1,000 Wh or more. For a furnace blower, you want 1,500 W or more of output and as much capacity as your budget allows — or an expandable unit.
Power stations are silent, produce no exhaust and can be used indoors, which matters in winter when you can't open windows. Fuel generators produce far more total energy and are better for multi-day outages, but must be run outdoors, away from windows, because of carbon monoxide.
