Emergency Preparedness Gear Guide
Grid failures from storms, wildfires, heat waves, and infrastructure aging are becoming more frequent and lasting longer. A well-planned emergency power and water setup keeps your household functional when the grid goes down -- no gas generator fumes, no fuel runs, no noise complaints. This guide covers the equipment categories you need for reliable home backup and emergency preparedness.

Preparedness Priority Order
If you are building your emergency kit incrementally, prioritize in this order:
- 1. Water filtration -- clean water is the most immediate survival need
- 2. Portable power station -- keeps fridge, medical devices, and comms running
- 3. Solar panels -- renewable recharging for multi-day outages
- 4. Battery bank + inverter -- scale up for whole-home backup
What You Need for Emergency Preparedness
Each card links to our best-for guides with product rankings, spec comparisons, and our top recommendations for emergency and home backup use.
Portable Power Stations
Home backup units (2,000-10,000Wh+) that keep your fridge, medical devices, internet, and lights running during multi-day outages. Look for UPS-mode and automatic transfer switching.
- ✓ 2,000Wh minimum for 24h fridge + basics
- ✓ UPS / EPS mode for instant switchover
- ✓ Expandable capacity for extended outages
Solar Panels
Portable and foldable solar panels that recharge your power station during extended grid-down events. No fuel, no noise, no maintenance.
- ✓ 200-400W for recharging home backup units
- ✓ Portable/foldable for deployment flexibility
- ✓ IP65+ rating for outdoor weather resilience
Water Filtration
Emergency water filters and purifiers that make tap water safe when treatment plants fail, or process creek/lake water if municipal supply is disrupted entirely.
- ✓ Gravity filter for no-power operation
- ✓ Portable squeeze/pump filter as backup
- ✓ Removes bacteria, protozoa, and chemicals
Batteries & Charge Controllers
Standalone LiFePO4 batteries paired with charge controllers for DIY home backup systems or supplementing an existing solar installation.
- ✓ 100-200Ah LiFePO4 for essential loads
- ✓ Long shelf life with minimal self-discharge
- ✓ Compatible with existing solar/inverter setups
Inverters
Pure sine wave inverters that connect to battery banks for a DIY home backup solution. Inverter-chargers can recharge batteries from a generator or restored grid.
- ✓ 2,000-3,000W for fridge, router, lights
- ✓ Auto-transfer switch for seamless switchover
- ✓ Pure sine wave for sensitive electronics
Emergency Power Needs Checklist
Focus on critical loads first. A 2,000Wh power station can run a fridge, router, lights, and device charging for roughly 24 hours. Add solar panels to extend indefinitely.
| Appliance | Draw | Daily Est. | Priority |
|---|---|---|---|
| Refrigerator/freezer | 100-200W continuous | 2,400-4,800Wh | Critical |
| Medical devices (CPAP, O2) | 30-150W | 240-1,200Wh | Critical |
| Internet router/modem | 15-30W | 360-720Wh | High |
| LED lighting | 20-50W | 120-300Wh (6h) | High |
| Phone/device charging | 10-30W | 40-120Wh | High |
| Sump pump (intermittent) | 500-1,200W | 500-2,400Wh | Situational |
| Space heater | 1,500W | 6,000-12,000Wh | Consider propane |
Emergency Water Needs
FEMA recommends 1 gallon per person per day for drinking alone. With a quality gravity filter, you can purify water from almost any freshwater source if municipal supply fails.
| Need | Estimated Volume |
|---|---|
| Drinking water (per person) | 1 gal/person/day minimum |
| Cooking & sanitation | 1-2 gal/person/day |
| FEMA 72-hour minimum (per person) | 3 gal total |
| Extended outage target (per person) | 1-2 gal/day for 14 days |
Plan by Outage Duration
Different outage lengths require different levels of preparation. Here is how to scale your emergency gear.
4-24 Hours
Typical storm outage
- Power: 1,000-2,000Wh power station
- Solar: Optional
- Water: Stored water (3 gal/person)
1-3 Days
Severe weather / infrastructure
- Power: 2,000-5,000Wh + solar
- Solar: 200-400W portable panels
- Water: Gravity filter + 5 gal stored
1-2 Weeks
Major disaster / grid failure
- Power: 5,000Wh+ expandable + solar
- Solar: 400W+ panels
- Water: Gravity filter + local water source
