Provide optimum charging for all USB-chargeable devices.
Most chargers are designed with a one-size-fits-all approach; they don't support the requirements of individual devices. Griffin ChargeSensor?? technology senses the charging requirements of any device plugged into it， and adapts itself to that device. The result is a single， truly universal 12 volt charger that provides optimum charging for all your USB-chargeable devices.

Griffin's PowerJolt Universal charger sports a low-profile plug for your car's 12 volt accessory outlet， and a universal Type A USB socket， ready to accept your device's USB charging cable. An LED power indicator glows to signal that it's properly connected and ready to charge. And its built-in， self-resetting SmartFuse guards against power fluctuations as it charges.
