Map the outage dependency chain before choosing equipment.
This is a static decision aid, not personalized safety advice or a product recommendation. Choose the closest situation and verify each dependency before acting.
Apartment or renter
Prioritize indoor battery or UPS options for essential small loads. A fuel generator is not apartment equipment.

- Which devices actually need power
- Expected outage duration
- Building rules and manufacturer instructions
Safety boundary: Do not run a fuel generator indoors, in an apartment, or in an enclosed or attached space.

Keep internet equipment online
Back up the full local chain: ONT or modem plus router. Powered Wi-Fi does not guarantee the provider network remains online.
Verify next
- ONT or modem power
- Router or mesh power
- Provider-side outage behavior
Safety boundary: A battery can power your equipment; it cannot guarantee upstream ISP availability.

Home office and short interruptions
Use UPS behavior and graceful shutdown as the decision frame before considering longer-runtime backup.
Verify next
- Equipment tolerance to transfer time
- Whether graceful shutdown is enough
- ONT/router dependencies if connectivity matters
Safety boundary: This planner does not size electrical circuits or provide wiring instructions.

Long outage or generator owner
Treat a battery as a quiet indoor layer and a fuel generator as an outdoor sustained-power or recharge layer.
Verify next
- Loads that need quiet indoor power
- Manufacturer recharge compatibility
- Fuel and runtime planning using official guidance
Safety boundary: Never operate a fuel generator indoors or in an enclosed/attached space, and never improvise a connection to house wiring. Permanent connections require qualified electrical work and proper transfer equipment.
