Capacity is the fuel tank; output is the engine
Watt-hours (Wh) tell you roughly how much energy is stored. Watts (W) tell you how much equipment can run at once. A 1,024Wh station does not run a 1,000W appliance for a full hour in normal use because conversion losses, reserve settings, temperature, and surge behavior reduce delivered energy.
For planning, use 85% of the advertised capacity as a conservative starting estimate. A 1,024Wh unit therefore provides about 870Wh of planned energy. Measure the actual wattage of critical devices with a plug-in meter whenever possible.
Do not size life-sustaining medical equipment from a marketing runtime chart. Confirm power quality, startup behavior, battery runtime, and backup requirements with the device manufacturer and medical team, then maintain a second independent plan.
Choose by the outage job
Phones, lights, radio, router
A 300–600Wh station or several quality power banks may be enough. Buying 1 kWh only for phone charging wastes money and carrying weight.
Refrigerator plus communications
Start around 1 kWh, then measure the refrigerator’s real duty cycle and startup surge. Keep doors closed and follow USDA food-safety limits.
CPAP or other medical equipment
Use measured overnight energy with humidifier settings exactly as used. Confirm compatibility and maintain manufacturer-approved backup options.
Heating, air conditioning, cooking
Portable 1 kWh batteries are usually the wrong primary solution for sustained resistance heat, central HVAC, electric ranges, or water heaters.
Seven checks before buying
- 01
List the devices that are genuinely essential, not every appliance you would like to run.
- 02
Record running watts, startup surge, and hours of daily use from labels, manuals, or a watt meter.
- 03
Calculate daily watt-hours and add a 15% reserve for conversion losses and operating margin.
- 04
Confirm the station’s normal continuous output—not a temporary lifting or boost mode—covers simultaneous loads.
- 05
Check solar voltage and current limits before buying third-party panels; wattage alone does not establish compatibility.
- 06
Search the exact model number at CPSC.gov before purchase and periodically afterward.
- 07
Test the complete setup before storm season, including cables, extension cords, recharge time, and a no-power fallback.

Power-outage buying FAQ
Can a 1 kWh power station run a refrigerator?
Often, but not automatically. Confirm the refrigerator’s startup surge and measured daily energy. A station may have enough output to start the compressor yet too little capacity for the outage duration you expect.
Can a portable power station run a space heater?
Many can technically power a small heater, but a 1,500W heater can drain a 1 kWh station in well under an hour after losses. Treat resistance heat as an emergency short-duration load, not a practical overnight plan.
Is a fast UPS transfer time enough for medical equipment?
Not by itself. A manufacturer-listed transfer time is not a medical certification. Verify the exact device, power waveform, transfer requirement, alarms, and backup procedure with the equipment manufacturer and care team.
Should I buy the solar panel at the same time?
Only after checking panel voltage, current, connector, and the station’s input limits. Solar is valuable for multi-day outages, but shade, clouds, window glass, orientation, and available outdoor space can sharply reduce output.
