Our verdict

A slim, mountable battery backup for signage, POS and edge gear, with surge protection on every outlet and tolerance for warm spaces. Its small capacity suits light loads, not a full desktop workstation.

Overview

A lead acid battery inside a slim plastic case takes over when wall power drops, so digital signage, POS terminals and edge devices stay running. The unit mounts on a VESA pattern, a DIN rail or a wall, letting it hide behind a display or inside a kiosk.

Mounting flexibility is the standout: it goes behind a screen, on a rail or on a wall instead of taking floor space. Capacity is small and the output waveform is not stated, so it belongs on light commercial loads.

Who it's for

Point of sale counters, kiosks and network closets with little room or limited cooling suit this unit. Home users powering a large desktop rig need a higher capacity model.

Pros and cons

Pros
  • Mounts on VESA, DIN rail or wall
  • Every outlet has battery backup
  • Handles warmer operating spaces
  • PowerChute Serial Shutdown compatible
Cons
  • Low capacity for larger loads
  • Few outlets for a busy kiosk
  • Replacement battery sold separately
  • Output waveform not listed

Performance notes

How long connected gear stays up depends on the load drawn against the battery capacity, so a light POS terminal runs far longer than a display near the full rating. Heat ages lead acid batteries, so a hot cabinet shortens battery life even within the raised temperature tolerance, which is where the replaceable battery matters.
