Battery chargers Nikon (eg P7700 and D5100 or Nikon 1V2) are actually quite handy, if they can operate with the built and aside foldable US plug. For Euro-plug but is an adapter that snaps securely into place on the charger and can be removed by selective, simultaneous jump in two small holes again with only two pens or screwdrivers. Very impractical so if you want to transport the charging unit in the camera bag as space-saving and a miserable fumbling it. US plug, fold out, plug travel adapter, charge the battery, after playing just detach the adapter and fold the US plug again: Here the mumbi travel adapter came into play. Although the charger has the Reisestecker little more game in the socket - especially hanging - than in their original state, but that affects the charging in any way. The travel adapter fits even then in the cavity on the charger, which sits while charging the battery. That's how I wanted it. Easy and space-saving. Thank mumbi!
