About this product

A 36W DC uninterruptible power supply built for the equipment that keeps your internet alive: routers, fibre modems, NAS boxes and small network switches. It holds a single 18650 cell and feeds the device through its own barrel DC connector, so on a power cut the router keeps running instead of rebooting. The output can be set between 5V and 24V, and that is the first thing to check: match it to the voltage printed on your router or modem power adapter, and confirm the barrel plug diameter and polarity as well. Network gear draws very little, so 36W is normally enough for a router and a modem together. How long it holds up depends on the load and the cell you fit, and the listing does not state a runtime, so ask the seller if that matters to you.

Pros & cons

Pros

  • 5V to 24V selectable DC output matches the voltage of most router, modem and NAS power adapters
  • Uses a replaceable 18650 cell, so a worn battery can be swapped instead of replacing the whole unit
  • 36W is enough for low-draw network gear such as a router, modem or small switch
  • Feeds the device through its own DC barrel connector, with no AC inverter stage in between

Cons

  • Rated at 36W, so it cannot carry a desktop PC, monitor or other high-draw appliance
  • You must confirm the device voltage, the barrel plug outer diameter and the polarity yourself, a mismatched plug will not fit
  • The listing gives no runtime figure; backup time depends on the load and the cell fitted, so confirm with the seller before ordering
