This is a 4-in-1 office accessory tailored for my wireless phone charger and Samsung Active 2 Watch charger. The product is compatible with the Ribivaul wireless charger and the magnetic wireless charger for the Samsung Active 2 Watch - however, you may need to add double-sided tape to the back of the chargers if they are loose. In addition, this product can store up to 5 USB drives and up to 5 pens with a maximum diameter of 0.54".
