A useful hurricane backup system is not necessarily the one with the largest battery or highest output. It is the one that can start your critical appliances, supply their daily energy, and recharge when an outage lasts longer than expected.
For a Florida household, that may mean keeping food cold, running fans or one room air conditioner, supporting medical equipment and maintaining communications. Identifying those requirements before comparing products is the most reliable way to avoid buying too little power or paying for capacity you will rarely use.

Calculate the Loads That Matter
Start with the equipment that cannot remain off. Record its running wattage, starting requirement and expected hours of use.
Motor-driven appliances require special attention. A refrigerator may consume only 100–250W while running but demand considerably more power when its compressor starts. Pumps and air conditioners can produce even larger starting surges.
The following is an illustrative daily-energy calculation:
| Equipment | Example use | Daily energy |
| Refrigerator | Compressor cycling all day | 1,200Wh |
| Two 50W fans | 12 hours | 1,200Wh |
| Router and modem | 20W for 16 hours | 320Wh |
| LED lighting | 40W for 5 hours | 200Wh |
| CPAP without heated humidification | 40W for 8 hours | 320Wh |
| Total appliance use | 3,240Wh |
Allowing for approximately 15% in conversion losses, the battery would need to provide about:
3,240Wh ÷ 0.85 = 3,812Wh per day
This does not mean every household needs a 4kWh system. Refrigerator consumption, CPAP settings and fan use vary, so actual devices should be measured with a plug-in electricity meter.
Cooling can change the requirement completely. Adding a 900W room air conditioner for eight hours consumes another 7.2kWh. The total battery requirement would then exceed 12kWh per day after losses. That is why cooling one room for limited periods is more realistic than attempting to operate central air continuously from a compact battery.
Compare the Main Backup Options
The following are broad 2026 planning ranges. Actual prices depend on capacity, installation, permits and local conditions. Recent AP coverage also notes that backup requirements differ substantially between short outages, heat waves and hurricanes.
| Backup option | Best suited to | Main advantage | Main limitation | Approximate cost |
| Portable power station | Apartments and essential household loads | Quiet, no exhaust during use and rechargeable | Runtime limited by stored energy | $200–$5,000+ |
| Portable fuel generator | Pumps, room AC and extended outages | High output while fuel is available | Noise, fuel and CO risk | $400–$2,500+ |
| Standby generator | Automatic partial- or whole-home backup | Starts automatically and supports large loads | Installation and maintenance | $8,000–$20,000+ installed |
| Installed home battery | Quiet automatic backup, especially with solar | No fuel and can serve household circuits | High initial cost and finite capacity | $10,000–$30,000+ installed |
A portable power station is generally the simplest option for indoor essential loads. A portable generator provides more output per dollar but must operate outdoors. A standby generator is better when central AC or automatic operation is essential. An installed home battery makes the most sense when the home already has solar or requires quiet, automatic backup.
Summarize
For most households preparing for hurricane season, a portable power station with roughly 2–4kWh of capacity, at least 2,000–3,000W of continuous output, solar charging, and room for expansion offers the most practical starting point.
It can keep a refrigerator, lights, internet equipment, phones, fans, and selected small appliances running without the fuel storage, fumes, and nighttime noise associated with a gas generator.
Homes that need to operate central air conditioning, electric water heating, well pumps, or several hardwired circuits should move beyond a standard portable unit and consider a higher-capacity 120V/240V backup system.
For outages that may last several days, the plan should also include a reliable way to replenish the battery. Buying more capacity extends runtime, but a workable recharging strategy is what makes the system sustainable.
