Worried your smart lock will leave you stranded in a blackout? Good news: the lock itself is fine — the real risk is losing the Wi-Fi that makes it “smart.” Here is how a power station keeps it all working.
The short answer
Most smart locks run on their own AA batteries and still open by keypad, app-over-Bluetooth, or physical key during an outage. What you lose is remote/app control and auto-lock logging, because those need your Wi-Fi router and smart-home hub — which go down with the grid. A power station keeps that network powered so everything stays connected. A small unit is plenty.
What actually loses power
| Device | Power source | Outage impact |
|---|---|---|
| Smart lock | Own AA batteries | Still works locally |
| Wi-Fi router / modem | Wall power | Down — lose remote access |
| Smart-home hub / bridge | Wall power | Down — lose automations |
So the fix is not powering the lock — it is keeping your router and hub alive. They draw only ~20–30 W combined, so even a small power station with UPS mode runs them for a day or more.

Frequently asked questions
Will my smart lock work in a power outage?
Yes, locally — keypad, Bluetooth, or key still work on its own batteries. You only lose remote app control if your Wi-Fi is down.
Do I need to power the lock itself?
No — power your router and hub instead. That is what keeps the lock connected and your automations running.
How small a unit do I need?
A router and hub draw only ~20–30 W, so even a 300–768 Wh unit runs them for a day or more.
