WHY DOES A PC/USB PORT CHARGE SO SLOW?
A regular USB cable is made to communicate (transfer data) and to act as a power supply between your USB port and your device.
When you connect your device (i.e. phone, table, etc.) to your USB port(on your laptop or in your car), USB port automatically prepares to communicate with your device and provide limited electric energy: to sync AND charge. Simply put, attempting to transfer data and charge at the same time is the main reason why charging is so slow.
Turning the switch ON to DouBBleTime mode results in faster charging time for your device when plugged into your computer or USB port in your car.
Fast Charging AND Secure
An added bonus of DouBBleTime Charging Cable-it protects your personal and private data stored on your devices by blocking data connection. When DouBBleTime mode is turned ON, the cable prevents accidental data exchange when your device is plugged into a foreign charge source. DouBBLeTime mode achieves this by blocking off the data communication between your phone and USB ports, allowing only power charging to take place (at DouBBle the charging pace compared to a regular usb cable).
