This problem will soon belong to the past for your guests – with the ratiotec TowerBank.
The TowerBank consists of the charging station, which you can connect to the power via the power supply, and six powerbanks. Since different ports are required depending on smartphone type, the set includes two powerbanks with microUSB, USB-C and Lightning* cables.
Recharging the powerbanks works by simply putting the stacked powerbanks on top of the station.
Allow your guests to charge their smartphones and provide an even more comfortable stay.
