Match the output to your device

The 3S Mini supports output voltages from 9 V to 19 V, with a maximum current of 3 A. Check your device’s power requirements before ordering. Its output must match the required voltage, and its current demand must stay within the UPS limit.

Four connector sizes are included in its output connection options. This gives you a choice of common barrel connections, but you should confirm the exact size your equipment needs.

A 4.4 Ah lithium battery powers the UPS, while its compact body measures 95.5 × 136 × 30 mm and weighs 400 g. It can fit neatly alongside compatible equipment without taking up much space.

Check compatibility before ordering

  • Confirm your device operates within the 9–19 V output range.
  • Check that its power demand does not exceed 36 W or 3 A.
  • Confirm which of the four listed connector sizes your device requires.
  • Check that a Type F EU mains plug suits your installation.
