  • the retractable prongs 66 of the charger device 46 allow the overall size of the device 46 to be reduced. This is particularly useful when traveling because the charger device 46 may be comfortably carried in the user's pocket or may take up only a small portion of a user's luggage.
  • the prongs 66 can be extended and retracted using one hand: a single push of the enlarged end 100 extends the prongs 66 from a retracted position and a push of the enlarged end 100 while pushing the prongs 66 against a surface retracts the prongs 66.
  • both the extending and retracting actions can be performed in situations where vision is limited by tactilely locating the enlarged end 100.
  • Another advantage is that by providing a retracted position for the charger device 46, the chance of snagging the prongs 66 on clothing or damaging luggage contents is reduced. Further, the chance of accidental stowing of the prongs is reduced by one or more physical features described above. For example, a user's action of inserting the prongs into an electrical outlet (whether due to friction with the outlet or misalignment of the prongs with the respective sockets) will not ordinarily cause the prongs to be stowed.
  • a charger unit (50) comprising:
  • a charger unit (50) as in aspect 3, wherein an end surface (106) of the end (100) may further comprise one or more features for facilitating user-location thereof, the one or more features comprising a color, a texture, a word, a logo, a symbol an characters.
