How long it actually holds the line

74Wh gives about 63Wh usable: around 5 hours on a 12W router, 1.75 hours at the full 36W, and most of a working day on a modem plus one camera. AC input keeps it topped up whenever mains is present.

Who it suits

Networking equipment in offices and small server rooms, where the load is small but uptime is contractual. Also used for access control and intercom systems.

Before you order

36W covers a router and a modem comfortably; adding cameras may exceed it. Ask for a load table.
Confirm the battery chemistry used at this size, because cycle life varies significantly between them.
Check the DC output voltage options against the equipment you intend to protect.

Listing note

Publish a load table showing which combinations stay inside 36W. A router plus a modem is comfortable; adding two cameras is not, and that gap is where most returns originate.
