Morphology
The meaning 'a device that supplies electrical power' is directly derivable from combining 'power' (electrical energy) with 'pack' (a packaged unit or module), yielding the straightforward interpretation of a packaged power unit. This noun–noun compounding is a regular, cross-linguistically common pattern, so a B1 learner who knows both constituents would readily infer the MWE's meaning.
Etymology
Power pack probably comes from the simple idea of a small pack or bundle of batteries that holds power. So today power pack means a device that gives electrical power to equipment.
