The XP3 uses a type C USB charging cable and the cables required to charge Sonim devices can be found on our website at: https://store.sonimtech.com/. Please DO NOT use a non-Sonim charging block or charging cable as this could damage the Sonim handset and would void the warranty.
Note: The XP5, XP6, and XP7 each use a propriety USB charging cable. If you need a charging cable for one of these devices, please visit our Sonim website at https://store.sonimtech.com/.
