About this project

THE PROBLEM 

When you’re always on the go and usually charge your phone or tablet with a laptop or PC in the office or an USB port in the car, have you noticed that charging this way takes a really long time? And it’s almost impossible to actually increase your phone’s battery power if you’re using it as a GPS even while your phone is plugged in into your car's USB port; that's because your phone is using more power than the power your USB port can supply to your phone.   

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.

THE SOLUTION 

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).

HOW IT WORKS

A simple yet ingenious special chip inside the switch talks to your computer saying, ‘I’m not a phone; I’m not going to sync, so give me maximum charging energy.’ This message allows the cable to bypass the capped out maximum power a USB can output and connect straight to the mainboard. The special chip also provides over current protection (OCP) and short circuit protection, which guarantees the safety of both your computer and device while charging. 

TESTING DouBBleTime CHARGING CABLE

TEST PROTOCOL:

We used several power sources in our tests; used the USB charging cable from the original phone packaging for each phone or tablet and the USB ports of several different laptops (both PC and Mac). In addition, various vehicles with USB port were used for car charging tests.

TIMELINE

In order to bring more than just a concept and idea to Kickstarter campaign, we have completed the following milestones:

  • Design Complete
  • PCB Tooling Complete
  • Environmental and Field testing Complete
  • Supply agreement Complete with MFI licensed USB cable manufacturer
We need your help to complete the following:
  • Plastic mechanical tooling for the switch.  We need funding to pay for tooling (mold)
  • Packaging design
  • Website design
  • Working capital to pay for raw materials
 

Why Kickstarter?

When we first shared the DouBBleTime Charging Cable idea to friends and co-workers in Silicon Valley, everyone said “You should check out Kickstarter!” And we asked, “What is that? How can Kickstarter help us complete this project?”

After researching Kickstarter, we fell in love with the idea of crowd-funding and even contributed to a couple of cool campaigns. We also reached out to other project creators whose campaigns were successfully funded and loved the sense of community and help we received along the way!

This is our first campaign and we’re super excited to have our ideas become a reality through the Kickstarter community.

Risks and challenges

DouBBLeTime Charging Cable 7 months in the making and it has been a rewarding experience to take it from concept to working samples. These working samples have been tested extensively to prove charging times and safety. We have already set up agreements with key suppliers (certified MFi connector factory) and contracted manufacturer. And we have expertly-designed printed circuit boards in hand. These are just a few steps we’ve taken to make sure the product is delivered correctly and on time!

Our biggest concern and challenge will come from manufacturing of our product. From the quality of the mold we will be making to final assembly, we have a very high standard and expectation. Meticulously overseeing the manufacturing to ensure we produce tight fitting and well functioning product will be our biggest challenge that lies ahead of us.

FAQ

  • DouBBleTime was designed with "faster charging on the go" in mind, with the added bonus of data security when connected to an unknown power source. If you connect a regular USB charger cable to a wall outlet, charging time will be similar to that of our DouBBleTime charging cable, but you will be handcuffed to a wall outlet and this usage case is not our primary objective nor the spirit of this invention. DouBBleTime is about fast, very fast, charging on the go: from car USB port, laptop, etc
