When an ice storm takes down the lines, homeowners start their generators. Renters usually sit in the dark. You can’t wire a transfer switch into a building you don’t own, and you should never run a gas generator on a balcony. A portable power station is the practical answer: a large rechargeable battery with ordinary wall outlets, which you can carry in, plug into, and take with you when you move. This guide covers what to power first, how to size a power station, what it realistically won’t do, and how to keep it charged when the outage lasts more than a day.

Step 1: Decide what actually matters

In a winter outage, most renters need four things, in this order:

1. Medical devices. A CPAP machine or other powered medical equipment comes first. Check the device’s power label and talk to your supplier about backup options.

2. The refrigerator. A full fridge loses its safe temperature after a few hours without power. Keeping it running saves both money and food.

3. Communication. Phones, a laptop, and your internet router and modem. These draw very little and keep you connected to outage updates and work.

4. Light and comfort. LED lamps, a heated blanket, a fan for a pellet or gas furnace whose controls need electricity.

Step 2: Know your numbers

Two numbers matter on every power station.

  • Watts (W) is how much power it can deliver at one moment. It must exceed the combined draw of everything plugged in at once.
  • Watt-hours (Wh) is how much energy is stored in the tank. It sets how long things run.

To estimate runtime, BLUETTI’s own formula for the AC180 multiplies capacity by 85% usable depth of discharge and 90% inverter efficiency, then divides by the load plus about 15 watts the unit uses itself.

In plain terms: a 1,152 Wh station gives you roughly 880 Wh of real-world energy. Run a 60- watt load (a router, a laptop, and a lamp together) and you get about 12 hours.

Step 3: The heat problem, stated honestly

A portable power station will not heat an apartment. A standard space heater draws about 1,500 watts and will drain even a large unit in under an hour. Plan to stay warm by other means: layered clothing, sleeping bags, closing off unused rooms, and an electric blanket, which uses a small fraction of a heater’s power while keeping you warm in bed.

If your building’s furnace or boiler runs on gas but needs electricity for its controls or blower, ask your landlord whether a plug-in connection is possible. Do not modify building heating equipment yourself.

Step 4: Pick the right size

For most one and two bedroom apartments, a power station of roughly 1,000 to 1,500 Wh with at least 1,500 W of output covers the essentials for a day: the fridge, communication, lights, and medical devices.

Our starting recommendation is the BLUETTI AC180 [AFFILIATE LINK]. It stores 1,152 Wh, delivers 1,800 W continuous, uses a LiFePO4 battery rated for 3,500+ cycles to 80% capacity, and weighs about 37 pounds, light enough to carry up apartment stairs. It recharges from a wall outlet in about 45 minutes to 80%. source.

If you need more runtime, the AC180P version raises capacity to 1,440 Wh in a similar package.

Step 5: Recharging during a long outage

A power station is only as useful as your ability to refill it.

  • Before the storm: keep it at full charge. Top it off whenever a winter storm warning is issued.
  • Solar: the AC180 accepts up to 500 W of solar input. A folding panel set in a south- facing window or on a balcony railing can recover meaningful energy even on short winter days, though output drops sharply in clouds and snow.
  • Car charging: most stations can trickle-charge from a car’s 12-volt socket while you drive. Never idle a car in a garage to do this.  Charging stations: libraries, warming centers, and businesses with power often let you recharge during extended outages.

Safety rules that are not optional

  • Never run a gasoline, propane, or diesel generator indoors, in a garage, or on a balcony. Carbon monoxide kills, and it travels into neighboring units.
  • Install a battery-powered carbon monoxide detector if your apartment doesn’t have one.
  • Never plug a power station into a wall outlet to back-feed the apartment’s wiring. Run devices directly from the station or through a heavy-duty extension cord.
  • Keep the station on a hard, dry surface with space for ventilation.

Your outage checklist

  • Power station charged to 100%
  • Plug-in watt meter to check device draws  Heavy-duty extension cord  Battery-powered CO detector
  • LED lanterns or lamps
  • Electric blanket and warm layers
  • Phone charging cables in one bag
  • Cooler and ice packs as a fridge backup
  • Utility outage line and app saved on your phone

The bottom line

You don’t need to own a house to stay powered through a winter outage. A mid-size portable power station keeps your food cold, your phone charged, your internet up, and your medical devices running, and it moves with you when your lease ends.
