A power outage is exactly when you do not want your security cameras to go dark. The good news: cameras are a tiny load, so a portable power station keeps them — and your internet — recording for hours.
The short answer
Wi-Fi cameras, an NVR, and a router together draw only 20–50 W, so a 500–1000 Wh unit with UPS mode keeps a camera system recording for 10–20+ hours and switches over instantly so you never miss footage. Our pick: the Bluetti AC180.
Camera system power & runtime
| Setup | Typical draw | On 768Wh | On 1152Wh |
|---|---|---|---|
| Single Wi-Fi camera | ~5 W | days | days |
| 4 cameras + NVR | ~30 W | ~22 hrs | ~33 hrs |
| Cameras + router + modem | ~50 W | ~13 hrs | ~20 hrs |
UPS mode is the key feature here: a true pass-through takes over in milliseconds, so your cameras keep recording the moment the grid drops — no gap in the footage when it matters most.

Frequently asked questions
How long can a power station run security cameras?
A single Wi-Fi camera runs for days; a 4-camera system with router runs ~13–20 hours on a 1 kWh unit.
Do I need UPS mode for cameras?
Yes, for continuous recording. UPS pass-through means no gap in footage when the power cuts out.
Will it keep my internet up too?
Yes — plug the router and modem in alongside; they only add ~20 W, so cloud cameras keep uploading.
