This 12V car adapter jack allows you to plug your project into your car&rsquos cigarette lighter for power on the go.

This is a very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. 

If you need to charge LiPo batteries, this simple charger will do just that, and do it fast! The SparkFun LiPo Charger Basic is stripped down of all features and just does one thing well - charge 3.7V LiPo cells at a rate of 500mA.

The NCP1402 is a 3.3V DC-DC converter. 

The LiPower board is based on the incredibly versatile TPS61200 boost converter.
