Stupid Martian power packs...

Unlike Ouroboros batteries, Martian power packs were notoriously unreliable. One such power pack was used in Kryten's Psi-Scan, and he notably struggled with it whilst trying to scan Dr. Hildegard Lanstrom's base.

Kryten still used it since he had an affinity for cheap, budget or economy models. ("Quarantine", Series V)
