The invention relates to a dual charging system comprising a rechargeable unit and a charging station. The charging station comprises retaining means and a base part, said base part having a charging seat with a projecting peg acting as a first electrode, around which an at least partly circumferential second electrode is arranged. The rechargeable unit comprises a notch, acting as a third electrode, and a fourth electrode, said third and fourth electrode is each arranged on the rechargeable unit to engage with the first and second electrode respectively of the charging seat when the rechargeable element is retained in the charging station. Hereby an advantageous charging system is achieved ensuring correct positioning of the rechargeable unit in the charging station, even under unfavourable conditions. |
