Backup power for Canadian homes

Quick answer

Backup power is not one product category. It is a decision tree:

Need	Usually start with	Why
Keep Wi-Fi, phones, lights, laptop running	UPS or small power station	Low draw, easy indoor use
Keep fridge/freezer cold for a short outage	Power station or generator	Depends on runtime and load
Run a sump pump	Battery backup, water-powered backup, or generator	Starting surge and duty cycle matter
Run household circuits	Generator with proper transfer equipment	Electrical tie-ins require a licensed pro

Size a generator without guessing: → Generator size calculator → Generator transfer switch Canada

Keep the internet on during an outage: → Keep Wi-Fi on during a power outage → UPS vs power station

Plan CPAP or medical device backup carefully: → CPAP battery backup Canada → Portable power station runtime calculator

Decide between power station, UPS, or generator: → Portable power station Canada → UPS battery backup Canada → UPS vs power station

Calculators and tools

• Generator size calculator — Running and starting wattage estimates
• Fridge/freezer outage calculator — Food safety timing with official baselines
• Portable power station runtime calculator — Runtime estimates from capacity and load

Build your backup-power plan

1. List what actually needs power.
2. Measure or confirm wattage.
3. Separate low-draw electronics from motor loads.
4. Decide whether you need indoor battery backup, outdoor generator backup, or both.
5. Add safety gear: carbon monoxide alarms, certified cords, and professional electrical work where required.
