The first item in the kit is a USB Wall Charger that outputs 5V at 2A. This switching 'wall wart' power supply is perfect for powering your USB devices when a computer is not readily available. The output is regulated to 5V, ensuring a steady and reliable power source.
Next, there is a Wall Adapter Power Supply that also provides 5VDC at 2A, but with a barrel jack connector. Like the USB charger, this 'wall wart' is a switching power supply, meaning it regulates its output to a stable 5V. It can provide a much higher output current, up to 2000mA, making it an excellent choice for power-hungry devices.
The third item in the kit is a Wall Adapter Power Supply that delivers 9VDC at 650mA through a barrel jack connector. This high-quality 'wall wart' power supply is also a switching power supply, regulating its output to 9V. It can deliver a higher output current, up to 650mA, making it suitable for devices requiring a 9V power source.
Finally, the kit includes a Wall Adapter Power Supply that produces 12VDC at 600mA, also with a barrel jack connector. This AC to DC 'wall wart' is a switching power supply, regulating its output to 12V and providing a higher output current, up to 600mA.
With the SparkFun Power Supply Sample Kit, power supply concerns for your next project will be a thing of the past. However, remember to include a USB Cable for your project if you plan on using the USB Wall Charger and don't have one already.
