What a power station can do in a winter outage
A battery station keeps the essentials running indoors with no fumes: the fridge, a modem and router, phones, lights, a CPAP machine. Many gas furnaces also need a small amount of electricity for the blower and controls; check the furnace label for its draw before relying on a station for it.
What it cannot do is heat a room for long. A typical 1,500 W space heater would empty even the 2,048 Wh BLUETTI AC200L (paid link) in little more than an hour. Plan for warm clothing and blankets, and use the station for the things that need electricity.
Cold-weather charging
Lithium batteries should not be charged below freezing. BLUETTI, for example, lists a charging range of 32 to 104°F for the Elite 100 V2. Keep the station indoors and charged before the storm arrives.
How we picked
Capacity and expansion for multi-day outages, a published UPS switchover time so the internet stays up when the grid drops, and a fast wall recharge for the short spells when power comes back. Our fridge runtime guide shows how to estimate hours for your own appliances.

Frequently asked questions
- Can a portable power station heat a room in a power outage?
- Not for long. A 1,500 W space heater would empty a 2 kWh station in a little over an hour. Use it for the fridge, internet, lights and medical devices.
- Can I charge a power station in the cold?
- Lithium batteries should be charged above freezing. BLUETTI, for example, lists 32 to 104°F for charging the Elite 100 V2. Keep the station indoors.
- Is a power station safe to use indoors?
- Battery power stations make no exhaust, which is why they are used indoors during outages. Follow the manufacturer's manual for ventilation and placement.
