So you want to charge your phone faster? DouBBleTime can help. It is a fast charging cable with a switch that enables charge only. When you turn the switch on, the cable will enable you to charge your gadget faster. DouBBleTime also blocks data connection, so your device won’t perform an accidental data exchange.
Here is how DouBBleTime 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 cable may not perform miracles, but it does enable you to charge your iPhone or other smartphones a bit faster. It also keeps your data safe. Early Kickstarter supporters can get one of these cables for $15.
