Why?

The reason behind the design of the portable power supply is simple: To provide access to a highly portable, variable power supply to engineers, students and hobbyists building and programming electronics in spaces where a typical power supply is difficult or impossible to use (remote areas, small labs, on-the-go programming, etc).  With the addition of a highly accurate current measurement module and Bluetooth connectivity, users can monitor the power consumption of their devices while programming, debugging or during deployment in the field.

Features

• 0 - 12V regulated output voltage
• 0 - 2A current output with current limiting function
• E-Paper Display
• Current measurements down to micro Amps, maybe nano Amps
• Bluetooth Connectivity
• Sub 1-GHz connectivity (optional)
• Fixed 5V USB output connection
• Micro USB connector for serial output
• Lithium Ion battery pack
• Power supply connector (used for charging)
