USB cables with magnetic connector
These magnetic USB cables help to protect the USB port of smartphones and other devices from breaking due to frequent connection or sharp bending of the wire. And in general, it is easier to connect the charger with them: you just need to bring the mating part and the connector will magnetize. However, not all cables support data transfer, some only allow you to charge the device. Usually, you can understand this by the number of contacts: if there are only two, then this cable is only for charging.
