Turn your coffee bar, hotel, bar, restaurant and exhibition booth to a service paradise.

While your guests charge their smartphones, they are able to study the menu and the beverage list,
which can be placed inside the power bank housing, without any hurry.


With this power bank your guests can charge their tablets and smartphones
while enjoying their time in your establishment in good company.

Even MP3 players and Bluetooth headsets with micro-USB ports can be charged.


Your advantage:
guests stay longer and so they consume more drinks and food.
