The data cable also has a charging mode

I believe everyone is not satisfied with the charge speed of their mobile phone, always hope to make time shorter, charging more quickly. Recently, a project named Doubbletime appeared on the Kickstarter. It is a USB cable for a smartphone device, capable of filling the phone with electricity half the time with a regular USB cable.

A conventional USB cable can be used to transmit data while charging the device, and this doubbletime cable is equipped with a switch that allows the USB cable to enter the "charge only" mode, allowing your device to be recharged faster.

Doubbletime's internal principle is not complicated, it has a simple special chip, and sends instructions to the computer not to synchronize the data, and then the information allows the cable to bypass the maximum output power of the USB and connect directly to the motherboard. Special chips can provide overcurrent protection and short-circuit protection, which ensures the safety of computers and devices. According to the actual test for the iphone, the current is about 500 ma before shutting down the data transfer function, and the current is about 1000 ma, and the charge speed is much faster.

In addition, when the data synchronization function is turned off, the security is relatively enhanced by blocking the data connection to protect the personal data of the stored devices and avoiding the exchange of data between your smartphone and unfamiliar devices. The role of this chip is to command the computer to avoid recognition as a smartphone, so the computer will not initiate the request for data exchange.

The Doubbletime data cable is available for PCs and Macs, with lightning and MICRO-USB two interfaces. It is still at the funding stage and the specific price and date of listing have not been announced.
